Electrical – How to test a three prong dryer receptacle for open neutral/ground

dryerelectricaltesting

I have a dryer that recently stopped working. After speaking with more than one appliance repair person, and trying more than one dryer, I'm sure the dryer is fine and some electrical fault is to blame.

The receptacle has voltage. A multi-meter reads 110 from each hot to neutral and 220 across both hot wires. I suspect an open neutral but my landlord is adamant that my dryer must be broken because there is power to the receptacle.

I would like to somehow show him a fault so he will stop blaming my dryer (and the second dryer I tried that also didn't work). I see that for normal outlets I can buy an inexpensive tester that plugs in and shows off a variety of faults using three colored lights. I can't find one anywhere that is designed to test the dryer plug. I believe it's a 1030 R. I've included a picture below in case I'm wrong.

Where can I get a circuit tester for this type of outlet? If that isn't really an option how can I use a multi-meter to test for the same things?

The dryer itself is the only load that is needed. Open the panel where the cord connects to the dryer and try to turn it on and measure the voltages from both legs to the ground/neutral and across the hot leads if the voltage drops out you will be able to pinpoint the loss with any meter. You may need to have someone push the start button while taking the measurements.
