Heat but no blower Lennox
Posted: Tue Nov 17, 2009 2:21 am
Hello,
I have an old Lennox electric furnace (E2SD 511-1 DM). I had a hot burning smell coming out of the return. I have the thermostat set to hold at 66 and the house will heat to 72+ from the heat coming out of the return. The fan is not on. The furnace is also warm. Is this a bad sequencer (12SH22) causing this, since the fan is not kicking on and the elements are heating? I have replaced the thermostat without any effect. If I cycle the circuit breaker everything works for awhile and then the symptoms return.
I am looking at replacing the sequencer and am wondering if there are additional components I should replace as well.
Kindest regards,
Tony
