Speed Queen Electric Dryer Trips Breaker

It trips instantly in heat mode. In no heat mode it runs fine.
Arcing on neutral...
Any ideas? Fairly new dryer, 5-6 years old probably.

“Bad connection on the thermal fuse. That caused heat which burned up the fuse externally. The temp limit switch may be just fine, but I’ll replace that also.”

Electric dryers can do funky things at times. One problem I ran into or rather had with my DE306 is the wire that went from the heating element to the high limit thermostat burnt out on me, and it did heat, but was making a burning smell. I happened to have the correct gage and color of wire, and I had it up in running with in a couple of days.

I actually posted in a thread awhile back (didn’t make a thread about it), but here’s what the wire looked like

Yep....

... looks like you found the problem!

A little poor contact, high resistance, additional heat, and finally the wire burns off the contact, falls away, and shorts to ground.

I'm sure the new thermal switch (and new wiring terminations!) will take care of the problem.

What Turbokinetic said. Agree 100%.

You should change those incorrect terminal block screws also. The far right is correct.

Probably going to have to replace the terminal block cause I’m sure someone forced those incorrect screws in. And might as well order new correct terminal block screws as well.

Burned heater terminal connections

Speed Queen and several other electric dryer manufacturers have trouble with terminals burning in the heater circuit. Only whirlpool uses actual silver plated terminals and almost never has this problem they’ve done it right for a long time.

You may also want to replace the heating element on this dryer if the mail terminals are even slightly discolored from overheating.

On the terminal block as long as the connections are good and tight it really doesn’t matter what type of screws are used.
