AC Fan Runs Constantly
Welcome to the forum!!
If your thermostat is square LED readout made by Dometic, then its real simple. The arrows on the right set the temp, and the button on the left sets the "mode".
Pushing the left button will cycle the mode from FAN to COOL to HEAT and OFF.
In FAN mode the right arrows will set the fan to "AUTO, HI or LO".
If the fan is set to either Hi or Lo and you set the thermostat to cool, the fan will operate all the time. If the fan is set to AUTO it will cycle with the compressor.
Come this winter when you set the thermostat to heat, if the fan is on Hi or Lo and your plugged into shore power, the AC fan will run along with the furnace fan. Set to AUTO it won't run with the furnace.
Hope this explains it in easy to understand terms.
