Hi all,
I have a problem with one of the thermostats on my coach. It's a Duo-therm ducted AC with furnace and heatstrip functions. The thermostat looks like this:
The problem I'm having is: it functions only when the temp setting is between approximately 80 and 90, no matter what the inside temp is. It works, but the setting doesn't match truly what the inside temp is. This makes it difficult to set it to the temp you would want it to be.
Any ideas what might be wrong? I'm not certain, but think the actual thermostat is located in the unit in the ceiling...that's what I hear "click" when the temp setting is adjusted.
If anyone has encountered this problem before and/or knows a fix, please help.
thanks a bunch!!
