Where do I get a new Dometic temperature sensor for the bedroom?

May 10, 2015, 11:59:28 am

I would like to replace the remote A/C temp sensor that is in the bedroom.  It just doesn't seem like it's sending accurate information.

I've looked and searched and I can't seem to find one online or a part number.

Can anyone provide me with a link and/or part number?

I think it's this thing in the photo?

Thanks

I believe that's a Dometic 3106486.008  ... may need to reuse your existing black cap though.

Dometic CCC and CCC2 Polar White 20' Remote Sensor Kit - Air Conditioner... claims to have it.

Thanks Steve.  That's not exactly what I thought was in there but that's exactly the info I needed.  I'm also realizing I have to replace the entire wire not just a sensor, and that wire runs up to the circuit board on the roof. 

Using the part number I found specs for Ohms at various Temps, guess I will test that before I pull a whole new wire.

Thanks again for the part number,  I have a much better understanding of how it works now.

I'd be willing to bet it is the same thermistor that is in the front thermostat, though it could have a slightly different ohm value due to the additional resistance of the wire's length.  If you buy the kit, you probably should not cut off any of the wire's length.  Or, as suggested by others, without running a new wire, it might we worth a try to simply solder in another thermistor in the bedroom location.  I've changed several thermistors in front thermostats because they became erratic.

I have been experiencing the same problem with zone 2 (bedroom unit) and the the thermostat is a 5 button Dometic CCC.  Spoke with a Dometic tech and he felt it either has to do with the  thermostat or remote sensor.  The first thing he suggested was to do a system reset on the thermostat by turning the on off switch to off and then at the same time press the mode and and zone buttons at the same time while turning the thermostat back on.  FF should show on the LCD display until you release the buttons.  If EE appears there is a communication problem.

Since doing the reset I was only able to run zone 2 for about an hour, it seems to have fixed the problem but the jury is still out until more run time.

Our rear AC control is on the left side of the bed right where I breathe on it when on my left side. I can adjust the temp by simply rolling over r stopping breathing. Same thing with the heat control. It's on the right side and in colder times the wife has similar control on it. We never adjust either...just toss and turn when we get uncomfortable.

You may want to spray a little compressed air over the sensors. Sometimes dust may affect how they work.

Thanks for all the responses.  Unfortunately re-initializing the thermostat didn't do the trick, tomorrow I'll try compressed air.  If that doesn't work, this goes on the back burner until June, when I'm going to replace the rear A/C shroud, and I can check Ohms.
