Thermostat Problems / Possible Change Out - Will It Work?
Our new Forester has the small Dometic single zone digital thermostat. Our 15k AC/Heat pump is acting crazy. When in heat pump mode, something in the roof unit will click eratically, the fan will start and stop real fast, maybe do that a second time, then it will finally stay on. When in AC mode, fan mode set in auto, if you set it low enough for high fan to kick on, it will run in high on start up. When the temp get's lower, instead of a smooth transition from high to low fan, the fan will completely shut off (compressor still running), then the low fan will kick on. I have no manual on how the thermostat / roof unit is supposed to work in THIS motorhome.
I've had many a 15k Duotherm AC's, and never have I had one act like this. I'm thinking the way it's operating, it's just a matter of time before it burns something up. I can only hope it has the soft start capacitor or it'll be gone soon with this quick start / stop thing going on.
I'm thinking maybe it's the thermostat, but not sure. Either way, I do not like this thermostat. It won't even show actual room temp, just whatever you set it at, unless I'm missing something. I'd like to change it out with the Dometic Comfort Control center like I had in a fifth wheel once.
Does anybody know if the Comfort Control type will directly replace the single zone thermostat, in regards to wiring and function? It's made for the same roof unit, but not sure if the control box in the roof unit is the same. Does anybody know what might be causing all the clicking and eratic behavior of the roof unit? I'm hoping it's just the t-stat.
Hoping the AC gooroos can help me out here.
