70 Series electric dryer.. no heat.. its not the heating element

[dans70dry]

About 1 month ago the dryer quit heating up.  Took it apart and the heating element was burnt in two. Replaced and has worked fine up until now.  Doesn't heat again.. this time it is not the element.  What else could it be?

Model 110.60942990

If lint gets on an element it can die quickly. Did you check for lint in the machine?

With your electric meter,check for 220 volts to the terminal block on the rear of the dryer first.
If 220 volts is present,unplug the dryer and check the thermal cutout on the heat canister as well as the hi-limit thermostat and the control thermostat,all should have continuity on your electric meter.

If the heater and the safety's are ok then the timer or the electrical connection may be bad.
The motor runs on 120 volts but the electric element needs 240 to operate. If a breaker is old and weak it will fail only on the heat circuit. The timer points can get fried over time with the load associated with the heating element.

I checked the thermister, it was fine.  Checked continuity on the thermal fuse.. everything checked fine.  When you press the switch it runs, but as soon as you let up it stops running.  Only if you press the switch and continue holding your thumb on it does it rotate, but never get heat.  checked element works fine.  Put it all together in the dryer and it doesn't heat up.

Could it be the "even heat control"?  anything else I could check.?

That start switch must be it. OR you has a broken belt.  Open the door and push in the safety then start the dryer to see if the drum turns. Let us know
Note: on some dryers their is a dang relay. Reg could give you the down low.

I'm not sure if the parts & wiring diagrams I have for that model are correct,
but there may be (2) identical Relays in the Control Panel.

One operates the Drum Motor, the other operatrates the Heater.

Besides the Start Button, they are both controlled by the Even Heat Board.

There shoud be 48v DC across the Relay Coil (smaller)Terminals.

I agree, thermostat is a good start.

Disregard the above post.

Flip the control panel back and next to the start switch there are two identical relays. One is a heater relay. And the other is a motor relay. If the dryer is not heating and you have to hold the start button in to make the dryer run, I would sugest replacing both relays.

Good to know Matt.
