Waeco CF50

yes mine went the same way , they had to drill into it place glue this new unit ontop of it, cost about $110

Yep, I've got a post on here about the same thing. Cost is around $110 to $150 if they do the "fuse upgrade" as well. They'll replace the thermostat (thermistor) and it takes a couple of days. Not a huge deal to fix but now I know about it I've met heaps of fellow campers with exactly the same problem. The good news is that once fixed it should go well for a long time with no troubles. Good luck.

Waeco CF50 fridge thermistor replacement

My Waeco CF50 recently decided to freeze everything solid for the second time in its life. The first fault was fixed under warranty, as was the warped lid.

The second fault I decided to fix myself, like the intermittent 12V power connector, the faulty interior light connection (replaced with high intensity LEDs) and the non-responsive buttons.

I found this post Waeco CF50 Thermistor archive during my research and thought Id post a follow up - which requires a new post on account of it having been archived. There would have to be plenty of folks out there with the same fault, which notably is the thermistor itself which had gone out of calibration rather than it having fallen off its mounting.

With already having had this fixed once I was able to 'reverse engineer' the fix. This is simply to remove the outer casing around the compressor, remove the compressor bolts, drop the compressor down a few centimeters, drill a hole through the insulation, glue a new thermistor to the evaporator then insulate and seal it all up again. If you're the type of person that's comfortable dismantling things its quite straightforward, providing you're capable of drilling a hole though the insulation but not into the evaporator.

I would post pictures and a disclaimer about my care but lack of responsibility should you ruin your fridge/life/wife etc, but there's no need. When you order a spare thermistor if you ask nicely it comes with clear instructions and suitable thermal mounting paste/glue. All for $22 plus postage.

Its all very straightforward. I anticipate saving around $300 by doing this repair myself should the fridge last as long as 3 years assuming the failure rate is around once every 2 to 3 years, which it would appear to be in my circumstances.

Interestingly the fridge has run quite happily almost continuously for over 12 months. It was only when it was switched off for a week that the thermistor failed almost immediately upon restarting.

I hope this is of some use to someone out there some day.

Check that the emergency switch hasn't been accidentally turned on. I forget what it is called but it is over ride, bypass or something. That happened to me one time and it kept going. It is to over ride the electronics if there is a failure.

Thanks everyone for your replies.
I have checked emergency switch and I am confident fault is thermister.
Just wanted to know what to expect $ wise.
I will be reasonably accept $150 after over 9 years of full time use .its been in 3 different vehicles.
unbolt it out of cruiser today and drop it to a service man.
cheers
