Question about Intertherm P3RA-048K Air Conditioner
I have no problems when the ac is on cool, but when it's on heat, the fan cuts on and off repeatedly. This started about 4 days ago. I've changed the thermostat wjth no improvement.
Either the circuit board or the relay that controls the fan in heating is dropping the fan out. it probably uses a different blower speed for cooling than for heating.. you'll need a meter to check if it is losing power.
Please rate this it matters to fixya.
