COLEMAN EB20B- furnace fan will not cut off

[brianjordan]

I have a coleman eb20b furnace. I cannot get the blower to cut off. the only way is to cut it off at the breaker box. Is this the fan relay or could it be in the sequencer? everything else seems to be working properly I have tapped on the relay hoping it would release but no luck. any ideas?

Hi,

For a/c , the blower relay controls the blower.

For heat, the sequencer controls it and it goes through the blower relay.


Blower Relay # 3110-3301 in Coleman Electric Furnace parts page.


Can also be a shorted wire in furnace blower circuit.



Thanks,
Robert
