AC outside fan fixes itself?
late last night I awoke from sleep and realized it was just too hot. I checked and found that the air coming from the registers was not cool. I went outside and saw that the unit was hot and buzzing loudly (assuming that means the compressor was running). However, the fan was not spinning. I immediately shut the unit off. I do some research and think that it probably has a bad capacitor, but when I go to cut the unit back on a couple hours later, it works perfectly.
What would cause a fan to randomly not start and then fix on its own? Should i preemptively call a technician or just wait and see if it happens again? I not sure if i want to risk it happening again and potentially overheat a crucial component.
Any help appreciated. thanks

It's probably the fan capacitor beginning to fail. You can either leave it alone and keep a close eye on it to see if it happens again and try the "stick test" (try pushing the fan with a stick to see if it will run with a push start). Or, you can bite the bullet and just go ahead and replace the fan capacitor. The capacitors are fairly inexpensive so, while that may not be the culprit, you're not out much if that doesn't solve the problem.

Could have a dead spot in the motor winding, it won't start on a motor winding dead spot area.
Could also be a fan run capacitor going bad.
It is hard on a compressor if the condenser fan does not start & run. If the fan-cap is incorporated within the compressor run-cap, just get the required mfd for the fan motor.
