Customer Question
in a trailer house that...
I am having issues with my thermstat kicking my AC on. I live in a trailer house that only has TWO wires to the thermostat. The unit has a switch for heat off cool as well as a fan switch that says on off and I think something else... I talked to my AC guy today about why my AC was running all of the time. He said, because it is only two wires...I cannot put the thermostat to COOL. He said I had to leave it on HEAT. ???? any ideas????

Customer reply replied 2 years ago
no. I have to flip the lower switch to the fan to ON...then it will run. It is not cooling any more tho.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago

I am not sure. I bought this trailer used. I cannot find a name on it anywhere.
HVAC Technician: BillyHvac, Journeyman HVAC Tech replied 2 years ago
your unit is an older version where the switch is on the furnace and you have to set seasonally for what you want. When in heat the thermostat is a heat thermostat...when in cool it is a cool thermostat.
The fan is supposed to kick on automatically in heat or cool without having the fan switch set to on.
In your case the relay or switching in the furnace is defective.
All that switching happens there..not in the thermostat.
You will likely need to have the switching relay replaced in the furnace....or upgrade to a 4 wire system...which in the trailers is not always easy
