I have a LUX 500 air conditioning unit for my home that's split (part of the unit's in the attic, the other part's outside). Recently the fan has stopped working, so no air at all's blowing out. Is there a simple fix to this?

Does it run when you set the tstat to fan/fan only?
If not, the cheapest 1st thing to do is find and replace the capiciter with exact match
If that doesn`t help/or work I `m afraid the motor probably needs replacing
