Our dryer does not heat any longer but it worked well since we moved into our home approximately 3 years ago. I don't know how old it is but it is in great condition. It runs well but just suddendly stopped heating. I took it apart and was going to order a heating element and to play it safe I was going to order the thermal cut-off for the heating element which included the high limit thermostat for $22.55. But now that I was looking further, I saw a dryer thermal fuse and a dryer cycling thermostat. Now I'm looking at more parts and of course more money. Without a multimeter, how do I know which to replace? Order all four and take a chance or just the heating element? thanks.

Forgive my ignorance, but do you mean the 3 wires going into the dryer from the 220 outlet?
My neighbor had a multimeter and the heating element was good, the thermal fuse was good, the thermostat going to the element was good but the other circuit, but I believe the cut-off for the dryer might be bad because it did not sound when we hooked up the prongs to the multimeter. Next I would like to check what you mentioned then I will probably need to check the other thermostat to the other side of the dryer that has the 2 red wires and 2 purple wires going to it. I neglected to have my neighbor check it out as I brought the other parts to him that I thought might be bad. Thanks.
