I own a GE electric dryer Model # DBXR463EG7WW. My dryer will not heat. I replaced the Safety thermostat Part Number:WE4M160 and it fixed it. I did 5 loads and no problem. I went to finish the last 2 the next morning and it wouldn't heat again. The place I ordered the part from sent me another Safety thermostat, maybe it was a manufacturer defect. It did not solve the problem. I then replaced the Safety thermostat (thermal fuse) Part Number:WE4M137 and Thermostat (4-wire) Part Number:WE4M181 and again still no heat. I then replaced the Mica Heater Part Number:WE11M10001 and again still no heat. I then replaced the Thermostat Part Number:WE4M216 and still no heat. Today I replaced the Temperature switch Part Number:WE4M411 and it is still not heating. I am running out of options and money. Am I able to test all of the parts for continuity? What else could be the problem?
