Fridge on the blink

Postby bromleyxphil » Sun Oct 28, 2018 7:36 am

Literally it seems to work perfectly sometimes then decides not to, it’s the freezer compartment that suffers the most. I can’t figure out any particular pattern at the moment but it was on last night when I went to bed and hasnt started up yet this morning. The temperature outside is around 0 degrees but that’s never been an issue before. I know Steve had a thread on this but I can’t find it and the search doesn’t work. Waeco CR1140 by the way.

This may be an explanation but doesn't quite explain it if you've never had problems before.

My CR140 is crap, turns on the off then on again.... day and night... it always has been and after constant arguing with Dometic they have now decided that as it is out of it's warranty, they wash their hands of it...

Not impressed!

They pointed me towards a local service engineer to find the problem, and when I rang him, he knew nothing about these faulty fridges..... This got me concerned but then it turned out he does not deal with compressor fridges....

I re-contacted Dometic to inform them of that and they eventually got back saying he has agreed to have a look and I will be charged for the privilege....

I think it is about time to create a Facebook page about how bad these fridges actually are, see how many people come out of the woodwork with the same issues....

I had loads of issues with one of the Dometic toilets, and after years of trying to get hold of Dometic to discus the issues with them, I managed to contact the head of the technical department who was a nice friendly and informative chap, so job sorted.

The same chap also told me to contact him about the fridge, and this was the first time I thought I was actually going to get somewhere with them, but then he left/moved and I was left dealing with the usual brick wall again....

Well it’s worked perfectly since I publicly denounced it!! I think the fact that I have vented the back to the outside has made it sensitive to zero degrees. It works in very cold and very hot but not in the middle. I will monitor it and report further when we have more zero days.

The normal dometic fridges don't work in cold weather. It's even in the spec.
The reason it that it's a cheap design. There is only one thermostat ( in the fridge, not in the freezer). And only one cooling circuit.

The freezer works by accident almost. If the compressor runs to cool the fridge, then it cools the freezer. But, if it's a cold day the fridge is cool enough and the compressor does not need to run. And therefore the ice-cream melts. Of course if it's really really cold the ice-cream won't melt anyway.

I hope that helps.

I think that is exactly my problem Mark. I have vented my fridge to the outside which is great in hot conditions but an issue 0 to +4 ish. I am going to work out a cover for the external vents and monitor it closely around that temperature. I may end up warming the back of the fridge with an internal vent. I will report progress on this later.

Well whilst driving along today the entire door of my Waeco CR140 just F$%*/@g fell off.

The bottom hinge socket in the door is actually made with plastic that is less than 1mm thick

Thats going to last

Aaaaarrrrrggggghhhh

Yup, that's about the long and short of it.

FWIW I ran a heater ducting pipe along the floor at the back of ours precisely to avoid the ambient temp in the fridge's installation location falling too low to operate properly.

Again FWIW, I also ran a similar system behind the leisure batteries to keep them in a 'happy' temperature range. Like compressor fridges, cold batteries perform poorly.

Bad luck Neil - hope you can figure a quick fix.

Brian - are you out there? You spoke of a 'Failure of Dometic Products' facebook page. I think it'd be a good time...

Since I wrote this page: http://www.triptruck.net/#/issues-and-f ... 4589698446 I have a few more personal fails to add.

Mmm, is this a case of domestic rather than dometic?
I'll get my coat :D
