HVAC

[69DAWG]

So this is my problem. I run the furnace at night to keep the temp up. I get up in morning cut it off and try and turn the hvac but it will not come on at all. Not even thr fan. I had bedroom fan going for the noise but then I cut that off and that will not come back on. Any ideas fir this problem? I turned off breakers and battery shut off and nothing. Please help

Need more details. What RV do you have? What part of HVAC is not working? HVAC is any equipment that keeps your RV at the desired temp, so it includes heater, a/c, heat pump, etc. Do you have one thermostat or zones?

I have a 2021 Georgetown. The both roof units will not cut on for some reason. All breakers are good. Even just the fans will not come on. Furnace works fine.

Are you connected to shore power?
Do other 120v items work?

[69DAWG]

Yes connected to shore and everything else in the rv is working. They units have been working so don't understand why they will not come on.

Will the fans come on if you set the mode to fan only? Does the thermostat control both the furnace and the a/c’s. Do you have only one thermostat or do you have a separate one for each a/c?

Not knowing which thermostat your Georgetown has, this just a wild guess. You wake up and turn off the furnace and turn on the HVAC expecting the heat pump to come on. Does your Georgetown have the heat pump feature? If it does, is it set up to automatically switch to furnace when the outdoor temperature gets down 40-45 degrees?


Heat pumps do not work well below 40 degrees.

A common feature of electronic heating/cooling thermostats is a temperature gap between heat and cool. This hysteresis prevents rapid h/c switching. You may be in that zone.

Happy camping

How long have you waited after turning the furnace off when switching to A/C?

No the fans won't even come on and yes I get up cut the furnace off and the try and turn on the heat pump but nothing. I do that to try and save propane. So I guess the units will not cut on unless the outside temp is above 45?

You got it, bro. If you leave it set to heat pump mode it will automatically switch back and forth as needed. Heat pump above 45, furnace below 45.

I have a auto heat setting. So I guess it hS to be on that so it will switch to furnace when it gets below 45 outside correct?
