Our dryer runs but we have no heat. Happened in the middle of a load.

Or Not!!!!!!!! No seriously, your model does not come up, but if you have the model where the back comes off the dryer, you might only need to replace the thermal fuse. It is white in color, and is about an inch and a half long, by a half inch wide. It has 2 wires coming to it. You can take the 2 wires off, and put the terminal ends together, and put some tape around it so it does not hit metal, and plug it in and see if it works, If so DO NOT run the dryer with the thermal fuse jumped out. It is a saftey. If it does not come on, it is either the ignitor, or the sensor. I would need to know if the ignitor comes on, after that to help you the rest of the way. Tom
