refrigerator has voltage running through outer casing?
 
My daughter was playing with my non contact voltage tester and to my surprise it lit up when she touched the refrigerator. I put a meter on a bare spot on the back and found that it has about 60 volts on it but very low amps. Any idea what could be causing this? I'm not that great with a meter but it appears that it is shorted to ground.

the non contact voltage tester is more than likely picking up the voltage from the anti-sweat heaters that keep condensation from forming on your fridge.

The fridge is running normal right?...then don't worry about it...

for fun...take the N.C.V. Meter to the supermarket and point it on the glass frozen food doors if you don't believe me.:thumbup:

Thanks. That makes since. I'll give it a try. Fridge works fine. I just didn't want anyone to get hurt.

What two points did you measure and get 60 volts? You shouldn't have any voltge at the outside casing, except for normal static voltage running around the ground/neutral circuit. Its usually only 5% not 50

NO it is not, what is normal about 60 volts running through the cabinet of a refrig??

Measured door hinge and grounded to my electric stove burner. Only getting 11 volts now. Strange. The NVC has a lower range of 50 volts.

Measure from the cabinet to the grounding prong hole on the outlet and see what you get.

I did not say anything about 60v running thru a cabinet is normal...

the refrigerator is running normal was a question to the op...

stop making trouble...and twisting my words...furthermore,60v to the cabinet don't you think the breaker would have tripped?...this is known as a short to ground!

I have young ones of my own! And IMHO if the op believes there is a problem I'm quite sure she will call a pro..:whistling2:

how is that twisting your words? You told her not to worry about it. She said she had 60 volts when she tested with voltmeter, to me that is something to worry about.

that is exactly the reason she came on here asking for advice, and imo she got bad advice from you.

Update: no voltage detected now. NVC meter is no longer detecting anything either. Not sure why. I also found that I have an open ground on the outlet so even more dangerous I think. Time to get some help and/or a new refrigerator. Thanks again.

The voltage is probably from the door heater. That is what is energized when you switch from energy saver to reduce exterior moisture. Im not sure if it turns off on the defrost cycle or not.

Plug it into a GFCI outlet. If the outlet trips, then you know that you have current leakage. If it doesn't, then you know that it was a fluke. As for the ground, if all of the outlets have the ground wire connected at both the outlet & the breaker/fuse panel, and you are able to measure voltage from Black to Ground, but nothing from White to Ground, you are good to go.
