My aerator circuit is not working. The motor works fine on

Customer Question

My aerator circuit is not working. The motor works fine on another circuit. My generic outlet tester says "open ground" when I check everything with my VOM I get continuity between ground and neutral 110v between hot and neutral, and 110v between hot and ground. Any ideas?

Hello and welcome to Just Answer. My name is ***** ***** I will be happy to assist you with your electrical question.

1) What is the N to G voltage?

Customer: replied 5 months ago.
2
Expert:  Kevin replied 5 months ago.

OK, that is a normal voltage then from N to G.

Have you plugged another load into the receptacle, does it work?

Customer: replied 5 months ago.
No I haven't.
Customer: replied 5 months ago.
Just tried a drill an it doesn't work.
Expert:  Kevin replied 5 months ago.

Check the meter in another known working receptacle. Possibly a low or dead battery on the meter?

Customer: replied 5 months ago.
My VOM
Expert:  Kevin replied 5 months ago.

Does the circuit have other receptacles or lighting on it? Do those work?

Yes, your VOM

Customer: replied 5 months ago.
Oh yes. It's fine
Expert:  Kevin replied 5 months ago.

Does the circuit have other receptacles or lighting on it? Do those work?

Customer: replied 5 months ago.
No. It's dedicated to the aerator motor
Expert:  Kevin replied 5 months ago.

OK, check the voltage directly at the breaker.

How many amps is the breaker and is the voltage 120v?

What is the motor FLA rating?

Customer: replied 5 months ago.
Ok. Stand by
Expert:  Kevin replied 5 months ago.

ok

Customer: replied 5 months ago.
124v at the breaker
Expert:  Kevin replied 5 months ago.

That is good then

Customer: replied 5 months ago.
20 amp breaker
Expert:  Kevin replied 5 months ago.

Try "rolling" the circuit hot wire over to another known working 20 amp single pole breaker.

Expert:  Kevin replied 5 months ago.

Does the circuit contain a GFCI?

Customer: replied 5 months ago.
Ok. Could take a little time
Expert:  Kevin replied 5 months ago.

No problem, just reply back to me and we can continue. Take your time............thanks.............Kevin:)

Customer: replied 5 months ago.
Ok. Switched breaker and still nothing. This thing is beating me up
Expert:  Kevin replied 5 months ago.

Does the breaker ever trip? What is the motor FLA rating?

Customer: replied 5 months ago.
No breaker doesn't trip. Not sure of the motor but it works fine when I run an extension cord from another circuit
Expert:  Kevin replied 5 months ago.

Hmmm.... am running out of ideas here.

Get a 3 prong extension cord and plug it into another know working receptacle and then take measurements and compare the hot and neutral using the female end of the extension cord to the motor receptacle.

See diagram shown below:

Customer: replied 5 months ago.
Ok. I just don't get why my outlet tester says open ground and the ground and neutral show continuity. Totally baffling
Expert:  Kevin replied 5 months ago.

How old is the home? Are you sure the circuit is grounded or possibly a bootleg ground exists at the receptacle?

At the female cord HOT, measure from there to the receptacle neutral. Should measure approx 120

At the female cord neutral, measure from there to the receptacle hot, should measure approx 120

At the female cord ground, measure from there to the receptacle neutral, should measure 0 volts or close to it

At the female cord neutral, measure from there to the ground at the receptacle, should also measure 0 volts or close to it.

Outlet testers have been known to result in false readings.

Customer: replied 5 months ago.
My other outlets are reading 122. Yes all those readings I gave you in my initial statement. 110v neutral to hot, 110v hot to ground and .2 grnd to neutral. House was built in 68
Customer: replied 5 months ago.
I put a new female end on the plug. I figure the male is fine since it works on other circuits.
Customer: replied 5 months ago.
If the neutral and ground are bonded at the breaker box, and I have continuity then doesn't that mean it's grounded?
Customer: replied 5 months ago.
Ok Kevin. I truly appreciate your help. I found the problem and am feeling very stupid. There is a timer box on the other side of my basement that I wasn't aware of. It had kicked off. Hit the reset and all seems to be working well. Geeeeze.
Expert:  Kevin replied 5 months ago.

Yes, N to G bonded at the panel means that it is grounded.

OK, glad that is was just the timer that was causing the problem. Sounds like you are back in business? Good job.
