Doughrainer, When you say "Per Dometic", what do you mean by that?

The original thermistor and the new Dometic thermistor that I purchased, both act the same.

I also purchased a pack of thermistors that are intended to solder into a circuit board. They are not the same, but similar. I soldered on some wires and surrounded in heatshrink. It works like it should. It turns the fan on high in freeze mode.

So the question is, is it the Dometic thermistors that are the problem or the circuit board? If there are only a few people with this problem, it isn't a big deal. But if thousands of us are having this problem, then Dometic should have their TS people just send a part as soon as a customer says they are having this problem. But so far, they are acting like this is an isolated and rare problem. They are telling me to call/pay a technician.

1. PER DOMETIC---That means I called Dometic and asked for the parameters. THEY said the upper control module.
2. I AM a Dometic Service tech(40 years and still working)
3. You MUST be an engineer. ONLY an Engineer would post what you posted and state there MUST be a inherent problem, instead of a minor glitch. HOW do you know if it is a few people, or possibly thousands?
4. I have rarely had a problem with the Dometic Freeze Thermisters. Maybe 2 or 3 in 20 years since this model thermistor was introduced. AND the failure was not sending the signal to shut the compressor down---failed to react to freezing evap temp.
5. If out of warranty, then you are OUT of warranty. If you are in warranty, get it to a Dometic service center. Doug
