it's mobile home no I don't live there that's my sister's place it's been doing it for a while when it's on cool if Rhymes Rhymes runs at very don't shut off it has a red and white wire coming from the lower one that's an older Coleman it has a switch for cold heat on furnace not put a Braeburn thermostat on it that has heat cool off and the AC will not shut off when it gets to room temp I'm wondering can I bypass that switch on the furnace to run a new start wire to make it like a regular furnace would work
HVAC Technician: airheatman, HVAC Technician replied 8 months ago

OK now here is the reason I ask.Normally in an older mobile home installation, there will be two thermostats mounted on wall.One for heat with only two wires fed from a transformer in furnace and then a second thermostat for ac with at least 3 wires fed from a transformer in the outdoor unit.Are you there now?

We can definitely convert whatever is there to work with a single heat cool thermostat if you have the patience and can follow my lead.
