Two of the dryers I have repaired have the same problem. The dryer
runs but no heat. It turned out one phase of the 220v to the dryer has
broken. The connector was corroded. So go buy a part ~ $1 and
reconnect the phase.
Actually there are several wires in a dryer that can burn off and create this
condition. Check all the wires and their connections looking for loose or burnt
One of the 220 leads burning off is pretty common. Then the element.
I had that trouble with a new dryer, and so called the store. They
told me to check the electric supply. Check for 240V between the hot
wires as well as 120V between either and neutral. Also, check that the
exhaust isn't blocked.
In addition to the fact that it is likely a cheap and easy fix, a DIY
for many people, you may find that it works much better than it has for
years. You may have been running on half power 120V for some time.
