Hello from Chuck
Problem with Dometic Duotherm Comfort Cntrol Thermostat led me to the Airstream Forum
. That's the Good News
. Bad news is that our Duotherm Comfort Control (four button) Thermostat
does not work consistently and we have been advised that the corrective action is to replace it with a new five button Comfort Control Thermostat. This isn't a simple matter of removing one thermostat and replacing it with another. The new thermostat requires a new control module on each air conditioner unit. Price for parts is about $290. plus labor. Another downside of replacing the thermostat is that the new thermostat has the same electomechanical design as the old thermostat according to Dometic staff.
There was an article in the FMCA magazine which described the problem and a possible fix. We tried the fix and it did correct the problem for a short period of time. The thermostat is now back to a malfunction mode.
Question: Has anyone found a real fix for the four button Dometic Duotherm Comfort Control Thermostat short of replacing the unit with a new thermostat and control modules?
Based on discussions on the internet. I'm not alone on this matter. In advance I thank you for any help you may provide.
