duo-therm 3106463.007 replacement thermostat
« on: September 15, 2017, 11:27:48 AM »
Greetings again. I'm in need of a replacement for my 20 yr old thermostat indicated in the subject line. Mine is a 4-button model which I have been unable to find on the internet. Everything I've found is either digital or has 5 buttons. Neither of these indicate what thermostats they replace. Anyone know if the new digital models or the 5 button model is a replacement for the one I currently have? Mine is a 2-zone model. The buttons on mine are: fan, mode, up, down. It connects to the heater/air conditioner via what looks like a phone type jack.

I see a few of the old Dometic thermostats still available on Ebay.

Your old one may also be repairable.

The conversion to the 5-button model requires a change to the zone controller. There is a kit for it:

Thanks for all the info. I'll check out the repair and conversion first. I haven't been a big fan of ebay, which is why I probably didn't come across the old thermostat in my searches.
