Roper electric dryer. Clothes not drying. Temp ok/timer not?

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

it might be the washer it is not spinning as much water out of the clothes as when it was new try double spinning the water out of the clothes

Hi, If your dryer seems to run forever and doesnt turn off, it could be because of a clogged vent or internal ductwork. Your dryer may have an automatic cycle that turns off the dryer when the clothes are dry. It does this with a special thermostat or moisture-sensing system.
Normally, this is what happens during an automatic cycle:
The thermostat tells the dryer to heat until the interior of the dryer reaches a pre-set temperature--say 135 degrees. When the dryer reaches the pre-set temperature, the thermostat tells the timer to begin advancing. (If there's a moisture sensor, the timer advances only if the moisture content of the clothing is low enough.) The timer advances until the interior cools, then the thermostat tells the timer to stop advancing, and tells the dryer to start heating again. This cycle continues until the clothes are dry. But if the vent is clogged, the dryer may never reach the proper operating temperature, so it doesn't send the signal to the timer and the dryer continues to run indefinitely, even if the clothes are completely dry. To fix the problem, clean the vent and/or internal ductwork.

chage the timer

The vent may be stopped up, or the vent hose crimped so the air cannot escape, you can check the air flow at the vent on the outside of the house while the dryer is running.
try cleaning the vent and the lint screen with a vacuum cleaner, you may need to replace the vent hose, this should solve the problem

forget temp ck..first ck air flow at rear of dryer be sure strong air flow present if not remove back ..remove 4 screws holding blower housing to inside wall remove the 2 screws under lint screen on top ..clean blower housing if housing clear ck vent line all the way to end outside for restrictions ..reinstall line to dryer be sure not to crimp or flatten hose when pushing dryer back to wall ...quick ck dry a load with rear vent hose disconnected if cks ok definite vent restriction

Most common cause of this is a clogged venting going to the outside to test this remove the vent from the back of the dryer and run a load if it drys ok them you know you have a venting issue and will need to be cleaned out if not plz repost and we can look deeper into it

Check your lint filter. Put it under running water to see if the water goes through it. Chances are it is clogged up. Wash it and put it back. Should do the trick.

Either the heater element is breaking or is loose and getting only 110V instead of 240V.  First I would check the wall outlet with a voltmeter for 240V between Line1 and Line2.  Also check the connections and continuity for the heater element.
