My Roper REX5635EW1 clothes dryer will not heat. I used an ohm meter to determinew the heating element and heat setting switch are fine. The control also seems to be ok as I have readings from the switch terminals as I run it through the cycle. What else could it be?
Dryer diagnosis can be challenging. While you wait for the expert to review the symptoms for your model, you can check a similar question from a previous expert post if you like. I attached below. If you decide you would like to schedule a technician to diagnose and make repairs, an option is Sears Home Services below.
The wiring diagram for your dryer is shown in the first image below. The L1 leg of the heating circuit is traced in red and the L2 leg is traced in green. If the L2 leg of power is missing, the dryer will not heat. I recommend that you check the house circuit breakers or fuses to make sure that they are not tripped or blown. The dryer will run with only the L1 leg of power supplied to the dryer. If the L2 leg of power is missing, the dryer will not heat.If you find no problems with the house breakers or fuses, then I recommend that you check the voltage at the dryer outlet. The diagram in the second image shows the voltage that you should measure at the outlet. You indicated that you were using a volt/ohm meter to perform checks on the dryer. Use extreme care when checking the live voltage at the outlet. NOTE: You should only check this live outlet voltage if you are completely confident in your technical ability to safely measure it .If the outlet voltage is okay, then you could have a problem with one of the other components in the heating circuit. You indicated that you checked some of those components. The thermal fuse is not in the heating circuit but there is a thermal cut-off fuse on the side of the heater box that could be blown. I provided a diagram of the components in the third image. I recommend that you unplug the dryer and check the thermal cut-off fuse, the high limit thermostat and the operating thermostat using your meter. You may find the cause of your problem in one of these components.These tips may help you resolve this heating issue in your dryer. If you need more assistance, reply with additional details.If you need parts, you can order them from the Sears PartsDirect website.Be sure that you unplug the dryer when accessing internal components.If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician.

Thank you for the expert advice. I was able to determine from my Internet research that the high limit thermostat is an open/closed condition and it was open. I found the replacement kit online for $4.95 plus shipping at a highly rated vendor. The old mechanic in me said that if it isn't working I should tear it apart and see why it did. Once apart I saw the bi-metal disk, points, and ceramic pill and couldn't resist cleaning the points and resetting the disk to see if it would work. Of course it did. The new one should arrive tomorrow. Oh how I miss the old days when you could fix things instead of throwing them away and replacing them. May you have a Blessed day today on this Easter Sunday.
