I have a Miller Model CMF80-PG propane furnace serial number MA0488-00496. When the T-stat calls for heat, the burner comes on and a short while later the blower kicks in but only runs for 2-3 minutes and shuts off for a minute or two before starting again. This continues until the set temperature is reached. I don't remember it being like this last winter when I bought the place. Any ideas?

Hi,

Is it just the blower motor kicking on and off ?



Thanks,
Robert

Thanks for getting back Robert. Yes, it is just the blower motor.

Hi,

Will have to contact distributor and see if they have a replacement Fan & Limit Switch and if so, what new part number is.


That would be first suspect. You can test it to see if it is opening and closing during cycle.




Thanks,
Robert

Thanks Robert. I will try and test it this weekend. Please let me know what you find.

Not sure that's the problem, but without being there, it would be my first suspect problem.
