Carrier heat pump model 38BYC024341 fan doesn't spin

When the heat is turned on, the heat pump fan doesn't spin. I hear the sound of the unit trying to start the fan, but nothing happens. I was able to get the fan spinning by pushing the fan with a small stick. Once the fan started spinning, it seemed to be working.

What is the typical cause of the problem and how easy is it to fix?

the typical problem from your description is a failed capacitor. It is easy to change if you can find a wholesaler that will sell one to you locally.

If your fan blades still spin freely or start with help then the capacitor is a good place to start. It can be a good idea to test the capacitor if you can before buying a new one. There are a ton if videos and how tos on it. Then you wont just be a 'parts changer' Keep in mind safety when working around capacitors, they can store a charge and need to be discharged safely.

Another big 'tell' is the fan shaft. There will be vertical play in it but no side-to-side. any rubbing on the interior of the motor will cause it to heat up and can signal a slow decline in a fan motor's life.

Last is wiring to make sure there is nothing stripped, bare etc that may cause a low voltage-high amperage situation to be going on.

good luck

changing the capacitor is cheaper than buying a meter to test the old one. $10 -20 for a new capacitor. $100 for a quality, trustworthy meter.

Wow, you get dual run caps way cheaper than we do here in Phoenix for a retail customer! Seeing how this is a DIY site it could be that basheesh could have a meter. Not out of the realm of possiblily.

I am kind of old school like that. I was taught to never just swap parts till you find the offending one.

Thanks for the advice. I will check the capacitor and see if that is the problem.

If the top of the capacitor is swollen it has definitely failed.
If it is not swollen it still may not be okay.


A swollen example...
