My 7 yr old Gibson AC compressor fan stops running after about 1 hour. What are the most likely part failure.
Although you did not say if the compressor continues to run for a few more minutes, I would assume this is the case. Otherwise, post a comment here, there may be other issues.
These fan motors have an internal thermal shutdown device to prevent it from overheating and creating a house fire in the process. The time that it takes to make it stop makes me think it's probably related to overheating of the motor. Does it run any longer if it's a bit cooler outside?
If it is overheating, there could be several reasons (least expensive first):
That's pretty much it in general terms. There may be other reasons, especially if there are more details to the issue you can share. Most important: what happens to the compressor when the fan stops. Does it cut off immediately (or, more accurately, do they both get shut off together) or does it continue to run until the pressure becomes too high and internal safeguards shut it off. If there's anything you want to add to the story, post a new comment here.
<strong>The power to the unit has to be shut off before you start!</strong>Thank you for your prompt reply to my post. As it turns out the Fan Motor was "dragging" and the Cap. was not up to par. what ever that means. Result, a new motor and Cap took care of the issue.
thanks again for your input.
