Coleman Evcon EB20B Electric Furnace

[BrianS]

I was wondering if the attic fan was bad would it cause the whole furnace not to work? My furnace stopped working and I went and removed the door and their was a red light flashing with no beeping above a green light. I looked on the furnace and it said if the red light was on and their was beeping their was something wrong with the attic fan. I went on top of the roof and looked at the fan and it will not move by hand at all. I changed the thermostat and there are no lights at all now. I can get the blower fan to kick on but the furnace itself will not do anything . Any suggestions? Thanks

Hi,

Use this to troubleshoot the blend air system:

It is just wired into the wiring, should not have any effect on the furnace operations.


Probably a bad sequencer if no heat, but blower works.


Sequencer # 3120A3571 can be seen and ordered through PayPal from left side of this page:
