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archive during my research and thought Id post a follow up - which requires a new post on account of it having been archived.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.

Indeed.

Oh, except the Engel uses a similar thermistor for temperature sensor.

But this wasnt supposed to be an Engel vs Waeco thread .... there are enough of those already :-)

I should add that in fact it's a thermocouple that's used. However if I put thermocouple people would have a hard time searching for this post since it's commonly (and incorrectly) referred to as a thermistor.

Hate to state the obvious Terry but you're having a bad run with that Waeco. :-( All I can think is lucky you don't go anywhere where you need to rely on it. (failure rate is around once every 2 to 3 years)

Terry,
Same problem in distant past. Techie offered to install a spare ($19) as he did the warranty job. Spare remains unused, touch wood.
