Heating, Air Conditioning, Fridge, HVAC/Heater blower malfunction


I have a Coleman 3500 690-A Mobile home heater.  The blower won't come on at all unless I manually cut it on.  The heating elements cycle on then off.  I have tried turning the breaker off for a few hours, then turn it back on.  The heater blower cycled once and then no more. What is the problem?


Sounds like a bad blower motor or possible a bad motor run capacitor from here. Do not run your heat if your blower fan does not come on as your tripping on the high limit.suggest calling for service, try putting the fan switch at the thermostat to ON from auto, if your blower starts and stays running then run your heat until you can call for service
