Hi,

That can be due to combustion motor being faulty, the centrifugal switch inside the motor being faulty or the comb. motor air pipe being damaged/clogged.


Most often it is the motor or switch and since the switch cannot be bought separately from the motor, either way requires a new combustion motor.


Let me know if interested in ordering info. Would need an hvac tech to test everything to see which one is at fault for sure.


Thanks,
Robert
