I'll have to disassemble the entire thing. Which sucks balls

Tore my parents down last weekend and it's in my shop waiting on new drum rollers and a new drum belt that will be here next week. It's not terrible to tear them down. There's really nothing to them.

ETA: This is what was happening to theirs to cause it to overheat.

Most dryers have a felt seal at the front and rear of the drum to prevent heat from escaping the drum. If the seal is worn out or missing, the heat will not be drawn through the drum properly, causing the dryer to get too hot. Check the drum seal to ensure that it is creating a reliable seal around the drum. However, this is rarely the case. Before replacing the felt seal check all the more commonly defective parts. If you have determined that all of the other components are working properly, replace the felt seal.

It's not always the thermostat and electric parts. The rollers that supported the drum and the drum belt were all going bad. The drum had slipped down some causing it not to operate correctly. When spinning, the drum rubbed against the metal of the front of the machine and caused friction plus it allowed the felt to be misaligned.
