Drum will not turn

Our Roper Electric dryer RES7745RQ0 will not work. The timer works, it heats, but the drum will not turn. We have cleaned it thoroughly and replaced the belt. We have tested the door switch, on/off switch, & it has power to the motor. What could be the problem?

    You should not have heat unless the motor is running to close the centrifugal switch in the motor. If the motor is running and the belt is good, it should be turning.

    Please verify what the dryer is or is not doing and report back.

If the motor is not running and the heater glows red you have a defective start switch on the motor.

Roper dryer works on high heat only


DID U CHECK THE HI LIMIT AND THE CYCLING THERMOSTAT? AS WELL AS THE MOISTER SENSOR?

Dryer venting issues slow drying, fire flare ups, to hot, noise and clothes ripping etc

A lint filter that is full of lint will restrict airflow and lengthen dry times.
A blower wheel that is not firmly attached to the drive motor can slip and therefore not move air fast enough to properly dry clothes or even reduce airflow to the point where the high limit thermostat may trip and turn off the heat circuit.
In gas dryers, defective gas valve coils can create a symptom of taking too long to dry if they are intermittent. Check for proper flame ignition for the complete dry cycle to determine if this may be the cause.

The drum seals are used to prevent excess air from entering the dryer drum and act as a cushion between the drum and the front and rear bulkheads. The drum seals are made up of a felt like material. If the seal is torn or is worn then clothing can become stuck in the gap when the drum is turning. This can produce a scraping or thumping noise and the clothes can also be ripped and/or have black marks on them.
DOOR SEAL When the door is closed in gas and electric dryers the door seal helps to keep cooler air from entering the drum.

The vent tube or line itself. If it is kinked, smashed, to long, or filled, clogged with lint build up it can not only cause slow dry times but create a fire safety hazard. Try to stay away from using plastic or flimsy cellophane venting, aluminum is best!

To provide better air flow and heat dissipation try the following
Note the length of your dryer vent is a determining factor in how efficient your dryer will perform. If the total length of your pipe exceeds 25 feet then your dryer simply won't be able to perform as should, especially if your pipe runs vertically and through the roof. This is where a booster fan is sometimes needed. Booster Fans provide the extra push of air to exhaust the moisture and lint to the outside. These fans operate only when the dryer is activated, this is done by sensing the air flow through the pipe by a pressure switch mechanism or an electrical sensing relay which in turn activates the booster fan blower. I personally try to avoid adding booster fans simply because they are usually placed in a crawl space or attic and are therefore "Out of sight and out of mind." What I mean is... the unit could malfunction and you would never be aware of it. The result would be a restriction in the pipe which would cause a build up of lint at the fan. In addition, it's recommended that lint traps be placed before the fan itself which has to be cleaned out frequently. These can also easily be overlooked.

1. On gas and electric dryers that have an "Auto Dry" cycle, the cycling thermostat is often used to advance the timer as well regulate the drum temperature. Essentially, thermostat will alternately turn on the heat source or the timer motor when the temperature has been satisfied. To check this thermostat, you will have to check for power to the timer motor with a multi-meter, during a cycle. This is a live voltage test and caution should be used.

2. Some dryers will use a cool down thermostat to tumble the clothes without heat, at the end of the dry cycle. Power is routed through this thermostat to the drive motor to keep it running until the drum temperature has dropped to a specific temperature. If this thermostat fails it can cause the drum to turn indefinitely or until the door is opened. You can check the thermostat for continuity with a multi-meter. This test should only be made with the power removed from the dryer.

Lastly check the moister sensor for OHMS according to ur schematic as it must show a certain amount of ohms as per ur unit. When unit has been on short while

Model RES 7646KQZ Drum turns, heat comes on, timer works, shuts off after 2-3 minutes.


either the high limit thermostat switch on the element case is weak or the cycling thermostat switch on the dryer blower housing is weak you can bypass both to test but dont leave them this way after youve found the bad component

I have a Roper Dryer Model REX3514PQO. The dryer


Sounds like you have a broken drum belt.
If you have to replace your drive belt and if you have a front loading machine.
First you will need to unplug your dryer from the electric.
Remove the front of the machine, this will expose the belt and drum, remove the drum and belt and this will expose the drum rollers, idler arm bracket with pulley, and motor with pulley.
While you have the drum out, I would also recommend that you lubricate the drum rollers at the shaft of the roller with a good grade of machine oil like 3 in One oil. This will save you problem later with the rollers getting noisy, also check your drum rollers for flat spots, if they have flat spots on them this will cause a noise like a thumping type noise. You will need to replace the drum rollers if they have flat spots on them.
If the belt is not broken, then I would check to see if the timer switch is working properly, if not then you may need to replace it.
Good luck,
I hope this helps

Roper Electric Dryer Heats but drum won't spin


Yank the filter out the top. Remove the 2 screws in the filter housing. Use a putty knife to pop the top and then remove the screws holding the front on. NOTE: raise up on the front panel slightly so you won't damage the bottom clips. Get the front out yer way and remove the drum. Clean out the dryer and oil the rollers and idler. Use this handy ROUTING GUIDE to see how to put the belt back.
