How do you know if your fan relay or motor is bad It is getting

Resolved Question:

How do you know if your fan relay or motor is bad? It is getting power but will not turn on. Went out of town and left my fan on for 5 days straight by accident. Outside AC unit turns on now that I replaced the thermostat, but no fan. How much would it cost me to have it replaced?

Hi,

 

If you are getting voltage to the motor and it is not running then its defective, or the capacitor is defective. More than likely the motor, the cost varies it can range between 200 and 450 dollars.

 

Thanks

Mark,

The capacitor has little black circles that looks like burns on it. Would this be an indication that it is bad and is there a way to test the capacitor? Capacitor is $98 and motor is $419. So hopefully capacitor. Thanks

Hi,

 

That would be an indication of a bad capacitor, tell me the numbers on it and I can probably give you a better source, those things are only about 30 dollars.

 

Thanks

I am at work for the next few hours and don't know the specific part number, but my unit is a Goodman A32-10 if that helps. I can check when I get off if you will be available then. I hope this fixes my problem, the military wages can make things tight.

Hi,

 

Yeah I'll need the numbers, 100 for that part is high and 420 for the motor is very high. here's the thing, if you replaced the motor you would have to change the capacitor also, so if you happen to buy the capacitor and it ends up being the motor it won't go to waste as you would have to buy it with the new motor anyway,

 

Thanks

Hi,

 

OK I see two terminals on it ? Sound right ?

 

Thanks

Yes. I did a Google search and found a new one on Ebay for $5.99 plus shipping. It looks exactly the same as the one I have.
Expert:  Mark Henley replied 5 years ago.

Hi,

 

That's about right, that's wholesale pricing. The only number that really matters on there is the microfarad rating which is 7.5. and you also want the same style for easier mounting , most are round but same are square. I would give it a try , you will also be surprised at what you can get the motor for if you have those numbers and end up needing it.

 

Thanks

I will try that first and see. Luckily it is in the 70s in Fort Worth and not the summer. Is there a way to request you if I need more help later?
Expert:  Mark Henley replied 5 years ago.

Hi,

 

Yes, in your question just put my name in it, thats the easiest way.

 

Thanks
