I replaced the sequencer on this unit a while back. Last winter my unit worked fine but this winter I have had issues with the fan starting . It worked fine during the summer with the AC. I believe it is an issue with the low speed on the motor. It does work intermittently but sometimes won't start....

I think maybe I left out something. The fan will not run at all when the switch is set to "auto" . I tested the switch and it's ok.

OK, finally got around to replacing the sequencer, but fan still runs all the time. There are 2 "auto/on" switches. I tested the switch on the control box and it is ok. The other switch does not seem to have any effect but I have not tested it. This is the switch on the furnace itself. Any...

Hello,
I have an Intertherm model FEHB-020HA electric furnace with AC. When in heat mode the blower runs constantly. The heating elements seem to be kicking off as they should Where should I look to solve this issue.
