On the back side of the dryer sits the heater and various safety clixons. Any of them that would be OPEN ( no continuity) would be the problem. Here are some repair pictures

See that white skinny component by the blower? That is the thermal fuse
Below it is the control T-stat. Now when that filter housing is clogged
The temps rise considerably faster. This control turns the heating element on and off during the drying session. So if you have this:

The autodry feature is not gonna work so good. Why?

See that orange wire attached to the high limit thermostat?
That feeds power to the timer motor if the heater element is not on.
Bad control thermostat AND/OR air restrictions are the Autodry type dryer's worst enemy.
Try first cleaning the dryer and see if that makes a difference.
If it still has problems then change out the control thermostat.

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

My Roper dryer ran a cycle with no heat then when I turned it off and tried to turn it back on...it will not come on at all. What might be the problem, I have checked the electric source and it is fine.


Hello, It is possibly the thermal fuse. Be sure to clean out the vent hose and the vent pipe to the outside to prevent over heating. If the vent system is ok then replace the thermostat as well as the thermal fuse. You can goto - http://www.searspartsdirect.com/partsdirect/index.action - to buy parts and get a parts breakdown of most brands. Just enter your model number and select model search.
Good Luck

CK IF YOU HAVE 220V COMMING IN OR THE HEATING ELEMENT IS GOOD. OR CK THE THM FUSE.IS NO GOOD. BUT IF DRYER RAN OVER NIGHT AND DIDNOT TRUN OFF YOU HAVE TIMER PROBLUM. THE DRYER SHULD TRUN OFF EVEN YOU HAVE HEAT IN THE DRYER OR NOT.
