Try check your timer, and see if you have voltage going to motor. Also check to see if you belt is installed. If broken there is a switch to the belt also. Try check you Door Lid Switch.

Roper dryer res7648kq0, replaced heat element, thermal fuse, cycling thrm, thermal kit, checked outlet, circuit breaker, still not heat, will not advance on AUTO, but will on timed cycle. Now what?


Wow.
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.

thanks,

Mike

We have brought home two new roper dryers now because neither one of them heats up. we hooked up a brand new 3 prong plug to the new dryers and plugged them into the existing 220 outlet that our old dryer...


You need to double check that your wiring it up correctly at the junction block on the machine. if thats correct. Most likley is that you actually only have 110 volts going to the machine it will run fine but will not HEAT. check voltage at plug or where its wired into back of unit you should have 110 volts on two out of three with the third being ground if you dont you have a bad outlet or breaker in elec.panel

Dryer electric when i push the start button nothing happpens


Make sure you have 220 Volts of power at outlet, check circuit breakers. Then, with dryer door open, look for door switch actuator on door. It may be broken. Use flat screwdriver to manually push door switch in, then push start.

LER4634E WHIRLPOOL FRONTLOAD ELECTRIC DRYER WORKED GREAT


If you have a access to an AC voltmeter, measure the two slanted connections in the wall socket for ~220 volts. If near zero, measure at the load side of the dual breakers for the same voltage. If still at or near zero, one of the breakers has gone south. Replace the pair of breakers.
If you measured 220 volts as above, then the problem is within the dryer--probably a burned out heating element or open thermal fuse. Major tear-down to find and fix as the heating element is behind the drum.

Dryer not heating


Electric dryers run on 220 volt, it is usually a double breaker at your main panel, however, depending on the electrician and how old the wiring is you might have two breakers, so start there first. If not, there are several parts to this dryer. It could be an element, a thermal fuse, high limit thermostat, or as simple as a burnt wire. Most important please turn off power before working on this.

The other thing that most people forget to check is the outlet pipe or vent pipe. If they get blocked, when the heat turns on, and it is blocked, the dryer will detect it and immediately turn off the heat but the drum will still turn. Bed Bath and Beyond has a dryer vent clean out kit that hooks to a shop vac.
Hope this helps!

Dryer does not heat up and now wont start!


Recheck for 220 at plug. May have tripped breaker.
PULL PLUG FIRST!!
Remove rear panel. Check for continuity at white thermal fuse located near bottom center on the blower housing. It should close to 0 resistance. Also check hi-limits on side of heater housing. Also should be close to 0 resistance. If any are open, replace and clear venting. Also remove 4 screws on bottom of filter housing and pull bottom of housing out. Reach in and remove lint.

Re: no heat and timer not moving


  If the timer is set for a auto dry cycle,  the timer won't advance if not heating.  You need to check for 220 volts at outlet.  It's possible to have only 1 110 volt circuit.  May be a bad breaker. or outlet.  If you have 220 volts at outlet,  you need to have an ohm meter to check continuity of the thermal fuses and the heater.   Access by removing rear panel.  UNPLUG FIRST!!!!!
