Question about Roper REX4634KQ Electric Dryer
The most common cause of no heat to an otherwise functioning dryer is failure of the thermal cutout.
As well as the electric line fuses in the circuit there are devices that look like this or this screwed to the exhaust air duct with wires to the terminals
, inside the dryer. If there is a lint blockage in the duct or fan or outside vent hood, the air tempoerature rises and melts out this thermal cutout (also thermal fuse, heat protector, heat cutout & any other names different makers use) before causing a fire.
Test with an ohmmeter or battery and lamp bulb, conducts good, no conducts fail-replace.
Despite the number of models of dryer there are only a few thermal fuses, and the local parts guy WILL have the blown one on the shelf, as GE if not as roper part.
Whil the dryer case is opened is a good time to vacuum out the exhaust vents, fan impeller, and vent hood. ounce of prevention and all that

In electric dryers with an AUTO cycle; the heater runs on 220 volts, but the timer motor runs on 110 volts. There is a resistor in the system to cut down the voltage. If the resistor is bad, you will see the same symptoms as if a thermostat was bad. The timer motor will not run in the automatic cycle. You need to make sure that you test for continuity in the resistor.
I've looked at two parts diagrams for your washer and cannot find a sensor anywhere in either, so the thermostat is what tells the timer to advance once the dryer reaches a preset temperature.
The thermostat will only tell the timer to advance if the dryer reaches the proper temperature, if you have some clogging in the vents, the dryer may never reach the proper temperature, and thus not advance on the auto cycle. but i'm sure you've probably checked that. I'm baffled. Let me know how it pans out if you can. Thanks. I'm still trying to find a wiring diagram for that model.

If your dryer is not heating, then check if the power cord is plugged into the wall. It may be loose or disconnected. Inspect the fuses and circuit breakers they may have burned out or tripped. Usually, dryer will still tumble but not create heat if a fuse or a circuit breaker is not working. Now, check whether the heating element in your gas dryer is burned out by using an ohm meter to check for continuity. If the continuity is not there then you would need to replace the element. After checking the element, check out the thermal fuse to see if it's burned out. The thermal fuse is attached to the exhaust duct on the back panel of the gas dryer. It's usually surrounded by a black resin material situated in a housing made of white plastic. If the fuse looks like it
