Air handler fan bumping on, off several times after normal stop.
by Rocky Jones
I don't have model numbers with me but is a Trane 1994 model air handler and I think it is a 1200 type. I am thinking it is something with fan delay relay. Sometimes when the unit stops after a normal stop you can hear the blower fan bumping on and off several times. I have turned the system off at the thermostat and it still behaves the same.
