Fridge woes

The van had been booked in at Kaitaia Tractors to get a change of transmission fluid. We had topped the fluid up ourselves whilst at Tauranga Bay but Garry pointed out that it probably needed a complete change. It’s handy having someone who knows about such things, he could tell by the smell of the fluid on the dipstick that it needed changing – who knew to take a sniff at the dipstick? Speaking of dipstick, the ones in the van are incredibly long…as in around 5 ft long!

We were due at the workshop first thing Monday morning so we headed into Kaitaia on Sunday to get a few chores done; laundry, shopping, dumping, getting fuel etc but we also has another pressing chore to attend to. The fridge wasn’t working, in fact it had well and truly died. How did we know for sure? From the very strong ammonia smell that happened on our way into Kaitaia. We knew straight away what was the problem so the fridge was immediately switched off and windows opened. We need to get it removed as soon as possible for safety reasons. But we have a freezer full of fish as well as other delights. What are we to do?

We were spending the night at the RSA and on booking in there and chatting with the bar staff, they very kindly offered to put out freezer contents into their large chiller. Brilliant, what a very kind offer. With that dilemma sorted, after delivering the van to the workshop on Monday morning we headed back into town to try and a) find someone to cap off the gas and remove the fridge b) find a replacement.

We knew we didn’t want another 3 way fridge, that is running off gas/12v/240v, we wanted a straight domestic 240v fridge. Initially we thought we also needed to have installed another solar panel dedicated to the fridge with its own battery, inverter and controller however that was proving impossible to find someone to do all of that. I made contact with Wayne Hunt from Motorhome Solar, as he did all our upgrades of our solar system a few years ago, yes he said, we can comfortably run an inverter compressor fridge on our system very easily, the brands to go for are Samsung or LG, he tells us. Great, now I know what to look for I can do some research. But what brilliant service from Wayne, his continued customer service is outstanding and we can highly recommend his company for good, honest, reliable service.

The other factor was the cost, approximately $3800 for a new 3 way fridge plus fitting including the services of a gas fitter versus $850 for a digital inverter fridge which we could fit ourselves (with help). A no brainer really. With the type of fridge sorted, the immediate priority was to find a gas fitter to remove the old fridge. Again, our fingers did the walking and we found a gas fitter in Kaitaia who could come first thing Tuesday morning and cap off the gas. Valentino from North Flow turned up as promised, on time, checked out our gas system, disconnected everything and then proceeded to get the fridge out of the van.

Getting the old fridge onto the trailer, Valentino offered to take it to the rubbish tip for us, how kind is that?

With specifications in hand we let our fingers do the walking, actually we got Mr Google to help us to find the right fridge. We are limited on size of a new fridge as it has to fit in the recess we have, not such an easy task it seems as fridges are rather large these days. After an exhaustive afternoon spent googling, going to visit shops, suppliers and phoning all over Northland trying to find the right one, mostly being told that they are unavailable, or I have to wait 2-3 weeks, with one place telling me it was a 6 week wait, I finally found a very helpful man in Whangarei at Barrell’s 100% Extreme Store. He went out of his way to be helpful, checking on stock, checking other stores before going straight to the manufacturer. He could get one delivered to us by the end of the week, he told me, brilliant, he even gave a bit of a discount too.

We have to say that the people of Kaitaia were extremely helpful and friendly, from the many businesses we made enquiries with, to staff at the RSA, the café we frequented (Manaaki on 25), where the staff and food were fantastic, we cannot fault the locals from being exceptionally helpful and friendly.

Going without a fridge for a week is going to be a challenge, as well, we needed to keep those frozens frozen for a day or two. Next purchase, a chilly bin and salt ice. The bin was packed with the ice and the frozens carefully placed inside with the the lid closed and taped down, everything should remain frozen until out next destination.

Chilly bin fridge!

We had a one night stop in Kerikeri before continuing on to Uretiti DOC camp where I knew that the managers Steve & Adrien would allow us to put our frozens into their freezer. We just had to wait a few days for the fridge to be delivered, and as promised I had a phone call to say they could deliver it to us on Saturday morning.

Fridge has arrived and is going well running off our solar array.

Sunday afternoon Garry arrived to help us with fitting the fridge into the recess. Some adjustments had to be made because the new fridge is taller than the old one, plus it has to be secured in place. Child proof locks were also purchased to secure the doors so they don’t accidentally swing open whilst we are on the move.

Oh look at all those wires. Remnants of the original American wiring plus new wiring. It was all tested, what could be removed was removed, the rest tidied up and carefully stashed. New wall linings were installed to complete the tidy up.

Of course it did not all go to plan, and new plans were constantly evolving. By the end of Monday we had the fridge in situ but not secured, as the final problem had to be overcome.

The fridge levelling feet at the front of the fridge were the problem and with no wriggle room left at the top we had to come up with another plan. The biggest issue was the left hand foot was under the base of the fridge but the right hand foot was under the hinge of the door, the door sits outside the cabinetry. After a good nights sleep with many ideas running through everyone’s heads, Garry came up with the perfect solution, we needed a piece of angle iron cut to length for the width of the fridge, this could be mounted flush with the base of the fridge with a long bolt threaded through the angle iron into position with locking nuts to effectively become the adjustable foot, as an added bonus it meant that the fridge would be bolted to the floor securely.

Looking through the vent hole and doorway, yes that is the fridge inside the door.
It looked like a building site outside.

A trip into Whangarei was required where we found a very helpful engineering company who had exactly the angle iron that we wanted plus they cut it to length and rounded off the edges. Perfect. Bolts were sourced and purchased and back we went to Uretiti. Holes were drilled, I painted the angle iron with rust proofing paint and once the paint dried it was all put into place. However, one of the bolts for the feet was too short to go through all the wood, so I had to go back into Whangarei to buy one more bolt. I was back by 5:30pm, bolt put in, angle brackets had already been secured to the back of the fridge and side bracing put in. It was all done. Woop woop.

We can’t thank Garry enough for all his help and able assistance, and it’s been a bit of a mammoth task as of course not everything went to plan.

Getting there, the final adjustments being made, Garry on the floor and Roy holding the fridge in place.
Voilà, new fridge in situ, bolted down in every way possible.
The old fridge was probably only as tall as the underside of the energy rating sticker, I now have much more usable fridge & freezer space.

We’ve now had the fridge running for a week or more and energy wise it is very very efficient, we get down to anything between 85% to 87% full overnight so we are thrilled with its performance. It is certainly going to save us some LPG usage with it paying for itself over a very short period of time. As well, it has ice making capabilities which has a certain member of the touring party delighted, lots of ice for his rum!!

We’ve got the power!

We thought we had sorted out our power issues however it wasn’t to be. The voltage dropped out overnight on a couple of occasions, other times it was ok and there was no rhyme nor reason to the voltage drop so we presumed that the batteries were probably on their last legs. It was time to get new batteries.

As a bit of background, we installed our battery bank of 4 x 230amp AGM deep cycle batteries just over 10years ago. It was all done by Absolute Power in Clevedon who did an amazing job. Last year we upgraded our solar capacity to 800W, and also upgraded our solar controller and charger, those upgrades being done in Hamilton at Motorhome Solar. We talked, at that time, about wether we needed to replace the batteries but they were tested and were ok. However, I will put my hand up and say 5hat we probably overloaded them this summer as during the day we switched the fridge over to power rather than run off gas. I think it was a step too far to expect the batteries to cope with the extra loading.

In consultation with Wayne of Motorhome Solar, over many messages pinging back & forth, we needed to get things organised. Wayne sorted a supplier of the new batteries for us in Christchurch. Which was after much discussion of what sort of batteries to go with i.e. AGM versus Lithium. We came to the conclusion that ;

a) we look after our batteries, as 10+years of continuous usage is probably double the life expectancy that many people get from them. (Note to self, leave the fridge on gas until we have to replace the fridge which we will do with an domestic fridge to run off dedicated solar, battery and inverter. I thought we would give it a go this last summer swapping the fridge over to power, in hindsight, not a good idea with old batteries! And yes, Wayne did say it was probably not a good idea but we thought we would give it a go anyway 🤦‍♀️. Lesson: Do as you are told! ).

b) we are not heavy power users i.e we don’t have or use a microwave, electric toasters or kettles (we use gas) and we don’t watch TV and if we do it is probably only to watch the news and then the TV gets switched off.

c) we are not restricted by the weight of batteries

d) taking into account the above, we could not justify the extra cost involved with lithium.

We were scheduled to have the new batteries installed on the Monday morning. On the preceding Friday we visited the battery supplier in Christchurch to just check out where exactly it was located, to familiarise ourselves with the route and to check that if indeed the van would fit into their premises. Just as well we did check as they tell us that they are just the wholesalers and don’t fit the batteries but they have booked us in with an auto electrician at another location. Off we trot to the friendly guys at Hornby Auto Electrical where we discover that indeed it would be a tight fit for our van to get into their forecourt plus they would have to ensure that their forecourt was completely cleared of all other vehicles to accommodate us. Hmmm, what are we to do? An easy solution they say, they would come to us and install them in situ where we are parked at Weedons NZMCA park. Excellent.

As per our arrangements on Monday morning we got a phone call from them to say that the young man was on his way.

An expert and his apprentice!

The installer tells us it’s always a concern when they fit on-site as they are not sure what they are going to need, as in, is our existing set up a good one? is the cabling the right size? etc but he tells us he was delighted to see that we have an excellent set up so it will be a simple swap in and out of the batteries.

One new blue battery in place

A quick and painless (apart from paying the account) process, it was all done very efficiently and neatly. We can now happily continue on our travels knowing that we have the power.

Fridge woes

It was blowing a gale, with horrendous horizontal rain….halfway through the day I could hear that the fridge was click click clicking away as though it was trying to ignite without success however all lights showing on the face of the fridge said that it was still going ok. In a brief respite from the weather we checked the back of the fridge (accessed from the outside) and it seemed that the flame was going ok but the starter thingy whatsit (that is it’s correct techie name) just kept on going and wasn’t detecting that the flame was actually present.

The outside vent and access to the rear of the fridge

Our fridge is a three way fridge, gas, 240v power or 12v, however we have had the 12v capability removed as it uses far too much power and would kill our batteries, therefore the fridge will only go on gas or 240v power. And as we very rarely, if ever, plug into power, it runs mainly on LPG gas. We presumed that the clicking noise something to do with the fact that the wind was directly blowing into the vent and rain was coming in horizontally on that side of the bus, possibly extinguishing the flame.

Fast forward to the following day which dawned bright, clear, sunny and no wind, however we discovered that the locker under the fridge vent was water logged so the rain was really coming in that direction with great force. Roy tried all the usual things to try and fix the fridge, he cleaned everything, blasted it with compressed air etc etc, until he determined that the control box starter thingy (another techie name) was faulty. He was sure he actually had a spare one but couldn’t remember where he had put it…..so, all the lockers got emptied, boxes opened and searched, he went through everything and couldn’t find it so he presumed he had carefully filed it at Antony’s for safe keeping.

Meanwhile we switched the fridge over to power and thought we would run it off the inverter and batteries during the day. We were already at 100% full by the time we thought of that option and with the inverter on, the control said we were consistently putting in 1 or 2 amps all day which made us think perhaps it wasn’t working properly on power.

Fast forward again to the afternoon, Roy went off for a nana nap, I decided to dry out and clean out the locker that had got wet which contains lots of containers with all those handy things like nuts, bolts, screws, fuses, wires, electrical connectors, and lots and lots of essential tools and bits, all neatly stacked in labelled containers. In tidying everything up before putting it all back neatly…..I opened one of the “miscellaneous” boxes and guess what I found? Yep, the little green box thingy all carefully wrapped up in bubble wrap!!! Once Roy woke up, he replaced the starter in the fridge workings and off it went perfectly on gas. Phew!

The replacement ignitor

But just to check, that evening we switched the inverter on, set the fridge over to 240v power and guess what? It uses around 27amps….amazing, so the system works really well during sunny days that means our power system is well setup and works extremely well.

We figure that for over the summer months, we shall run the fridge on power during the day and gas overnight, and see how it goes especially whilst we are at Shakespear, hopefully it will reduce our gas consumption considerably.

The fridge workings exposed, with new drainage hose attached and new ignitor in place

PS to the tale of the fridge, we thought initially that the wet locker was from the rain, but no, on inspection the drain hose at the back of the fridge to the outside (that white crinkly concertina pipe stuff) had completely broken down and shattered into tiny pieces with the water now dripping down into the locker below.

Some years ago we had replaced large section of the hose but the last remaining 6inches of pipe at the fridge end had deteriorated so we needed another hose to connect directly with the fridge outlet. The replacement piece we had on there just wasn’t doing it as it was very stiff and I couldn’t bend it enough to directly connect it to the back of the fridge. You must realise that I am trying to do this from the outside (the back of the fridge) through a narrow gap which can only be reached if I stand on a step, angle myself into all sorts of twisted positions to feel my way past all the other pipes and wires…..so, thinking cap on. What can we use for a better drain pipe of the correct dimensions…..light bulb moment, the clear flexible hose from one of the solar showers fitted perfectly and was pliable enough to squeeze directly onto the outlet pipe at the back of the fridge. Voila, it works perfectly.

The woes of RV fridges!!!
