Nordyne Electric Furnace blower fan will come on with ac but won't with heat. but you can put fan on on and it works but if you put it on auto nothen. and you can hear when you trun the heat on after a bit the click like it is trying to tell the fan to come on. then it get hot but no fan.
Was told it could be relay so we changed that. didnt see any change. was told it could be transformer or sequencer. So not sure what it could be. Help.

Thank you

Hi Sue,

Most likely a bad sequencer. Will need furnace model number to help further.


Thanks,
