I have an old GE electric furnace. When I try to turn on the air conditioning the outside fan works but the furnace does not come on. I went downstairs and I could hear that power was reaching the furnace so I turned off the power at the circuit breaker, and then turned it back on and nothing happened. I turned off the circuit breaker again to check and see if the fan blades were stuck and I was able to spin them freely. I decided to try spinning the blades and turning the circuit breaker back on and it worked, however it shut off again in about thirty minutes. I tried testing the heat and it worked under the same conditions and for the same length of time. :confused:

It could just be the fan motor capacitor is defective but it is also possible the motor itself is going bad.

I have ordered a new capacitor, will report back once I have installed it. Thanks for the information.

I just replaced the capacitor and it worked! Thanks again!

Glad you got it running.
