Roper dryer timer will not advance and there is no

I fixed a roper dryer with a no heat problem and I did a youtube video you can google Roper Dryer no heat if my movie does not show but I gonna post it for you.

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

If the timer does not advance even on the time dry cycle then you have a bad timer motor. You would need to replace the timer to rectify the problem. Hope this helps _MJ_

my roper dryer does not heat up i checked thermostat, thremo fuse and heating element they show working could it be my timer when dryer is running timer does nt advance it stays in the same position.

If you have a TIMED cycle,the timer should advance heat or not. In the AUTO dry cycle the timer will not advance without heat. Unplug the dryer. Remove the rear panel of the dryer and check the heat element, relays and thermostats with a volt meter set for ohms. No reading indicates a bad part. Remember to remove at least one wire from each component before testing.

you either have a tripped curcuit breaker or your heating element is blown. If the timer cannot sense that the heater is in the curcuit it will not advance check your curcuit breaker first. flip it on and then off and let me know if you have heat

Will the dryer move forward in timed dry? if it does not then you need a new timer. If if will advance in timed dry but does not advance in auto mode then the high limit needs to be replaced on the heater.

hi i think the motor is unstable so the drying ability is decresing check and service it

hi first thing to do is clean all the venting and try again. thanks the appliance doc

  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!!!!!
