240v Dryer Outlet Issues


I've been trying to troubleshoot my dryer for the past couple months to no avail. So far I've replaced the heating element, and then the electronics control board per what the technician's guide said to do.

I've been inspecting the outlet (which I should have done initially) and I'm getting around 120v from each hot wire to the neutral and to the ground. I'm not getting around 240v from one hot to the other however. I am only getting 104v and I was wondering if this is actually normal, and if not what could be the problem?

I am testing voltages from the end of the cord btw, since my multimeter isn't able to get a reading in the deep 240v outlet.

240v Dryer Outlet Issues


Ayuh,.... You should be gettin' 2 legs of 120v each, for a combined 240v...

Which it sounds as though ya are....

240v Dryer Outlet Issues


My only question is when you go from the two hot sources it won't read around the full 240v?

Any electrical work lately?
Do you have fuses or breakers?
Have you reset the breaker?

240v Dryer Outlet Issues


Moved into a new apartment and the dryer worked for about a week before it stopped working. Haven't been able to solve the problem in the few months since then. It has a set of two breakers to the outlet that I've reset a few times.

Are you testing the outlet voltage with the dryer plug totally removed?

Did this dryer previously work plugged into that outlet?

240v Dryer Outlet Issues


It worked for around a week in the same outlet and then stopped working. No the plug is still attached to the back of the dryer, do you think it would read differently if unhooked from the back?

There should be a double pole breaker.
Start with that issue when you call your landlord.

It is a double pole, my mistake for making it sound like two separate breakers. That's just the way I think of it since it spreads over two breaker spots.

Turn the breaker fully off, then back on.

And if measuring the voltage with the dryer still plugged in, one "hot" might be working and the other "hot" not working. But the hot voltage travels through the dryer to the other hot. Thus you get a reading.

With the dryer unplugged, that non-working hot would (should) not have any reading.

Possible just half the double breaker tripped or there is a wiring problem like a loose connection (landlord problem if a rental).

P.S. Turn OFF the breaker before unplugging it from the outlet (if you are going to do that). Do not disconnect the wire from the back of the dryer for testing the voltage!!!!

what sort of tool would I need to test the actual plugs of the 240v outlet. The contacts on my multimeter aren't long enough to get a reading from any of the outlet plugs so I don't have a way to test it without the dryer being plugged in.

You're dealing with 240v at high amperage... ever heard of Arc Flash?
