Dryer runs very hot and shuts off

Not much left. I would check the venting. These are a few things to look at.

While your dryer is still running, and before you disconnect its power supply, place your hand over the exterior vent while it is running. You should be able to feel a strong air flow. If the air flow is weakened at all, check the following areas:

A common culprit for an impeded dryer air flow is a blocked lint filter. Remove your dryer's lint filter.

If you clean your lint filter regularly, check the venting hose. Make sure it is securely connected to your dryer and the external vent. Also, if your venting hose is kinked, it could create lint build up and poor air flow. Do a check of your dryer's venting hose to make sure it is not bent in an awkward position.

Unplug the dryer and pull the unit away from the wall. You are going to need to get in behind it. Remove the end of the hose that connects to your dryer. Take a look for lint build up, or any other sort of blockage. Also do a check for any holes or tears in your venting line. Plus check the venting line inside the dryer, and use a vacuum cleaner to remove any excess lint. Repeat this process periodically.

Reattach your venting hose in the shortest, most direct way. Avoid letting the hose drag down low, because those low points are prime lint-accumulating areas.
