Another thermostat question

I have the single zone thermostat in my Ď17 345rl. I canít get the ac, heat pump or, furnace to work. Any thoughts. I would try a reset but, canít find the manual for it. Also have checked breakers. The unit will switch modes and temps but, wonít turn the fan on or anything else. TIA.

Try turning it off for about 5 seconds and then back on.

I have an issue as well. We have 2 zones but on the main zone if I switch it to the furnace , the AC unit also turns on the fan. The only way I can get just the furnace to go on is to turn the AC breaker off. It’s on the warranty list for the end of the summer . . . . . I gues we are there.

Yep did that a few times. Even left it off for an hour at one point.

I found this youtube about that thermostat, but no manual. You might call Dometic if you can't get it working. You do have power to the heater and A/C?

I saw that video thanks. Not sure about the power though. No volt meter with me.

Do you have the fan set on Auto when you run the furnace. If not you'll get what you describe.

I just checked double checked and no it is not on auto. It’s very strange.

New twist to my problem. This morning I get up and it’s cold in the coach. So I turned on the fireplace to take the edge off. Then I thought try the furnace. As I scrolled through the thermostat I see the heat pump option had disappeared. Turned it to furnace and it fired up and worked.( unlike the last two days.) about 5 minuets later I scroll through again and, the heat pump option is back and, working. Can’t wait for tonight when I get back from work to see if the a/c is back working. Either way I have an appointment on Friday at the dealer for some warranty work including this problem.

There are known issues with the newer thermostats. If you call Dometic they will most likely send you a new one.

Thanks DQ. All I’m working fine again. The rig is going in Friday for this and other minor problems. If they don’t figure out the thermostat problem I will call Dometic.

Looks like a thermostat in bed room which will not operate furnace or heat pump. AC only

I dropped the rig off last weekend for warranty work including the thermostat and ac controls. We also have no heat or blower from the fireplace, just lights.

Dealer called yesterday to tell me they were done. I was told there were some bare wires up on the main unit that they fixed. He said they must have made contact while going down the road. Not saying he’s wrong but, when this all started the unit had been set up for two months and not moved. We’ll just have to get it set up again at the next job and see how things are. The good thing is the dealer only had it for and a half and got all the items fixed. This is one of the good guys.
