Heat but no blower Lennox

[tdohse]

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

Hi Tony,

I don't have any data on that unit, would need wiring diagram to see if anything else in circuit. However, from what you've said, that is most likely the problem.


If you need help getting the part, call Mark toll free at 1-877-263-7860 and give him the info off of old sequencer to match it up.


Thanks,
Robert
