Electrical outlet is reading “correct wiring” but doesn’t work

electricalreceptacle

Last night I noticed the fridge in my garage was no longer working. I unplugged the fridge and plugged a cell phone charger into the same outlet and it didn’t work either, I checked the circuit breaker and nothing was tripped and I tested and reset the GFCI outlets. I used a voltage detector pen and it indicated the outlet had power. I then used a receptacle tester and it indicated hot/ground reversed. So I checked all the outlets in the string leading to the main breaker and couldn’t find any with the hot and neutral reversed. I installed a couple new outlets anyway and disconnected and then reconnected the neutral wires. Now the receptacle tester says correct wiring but the outlets still do not work. Help?

Ah, the "magic 8-ball" testers.

The legends are useless. Hot ground reverse suggests it is seeing power between hot and neutral, and neutral and ground. Nothing says the voltage is 120V. For lack of a neutral, HN and NG lamps were in series seeing 60V each. This was a lost neutral. Hot and neutral were never reversed. I hope you did not reverse them in an effort to clear this message!

A hot-neutral reversed combined with a lost neutral would also read "correct" and yet not work.
