Is your inside fan not working on your AC unit? This maybe the solution. Air Conditioning repair in Rancho Cucamonga Ca. with Apco Appliance and Air. This unit wasn’t cooling but the outside condencer would run. The problem is that the inside blower motor must run also and it wasn’t. If this unit had a circuit board at the furnace blower then the problem would be the thermostat or circuit board more then likely, but it didn’t. This unit has a fan relay switch that is ingaged by a 24 volt coil. The relay coil was getting the 24 volts but the contacts were not connecting inside the relay to send power to the fan motor. Sometimes you can smack it with the handle of a screw driver and they will start working again. Remember that you must turn the power off to any unit you attempt to work on.
