Gets hot and stops

Sound like thermostat is not working. Should turn off heating elements when drying temp. is reached.

make sure all the venting is clear of build up and debris,, clogged venting will not allow the moisture to escape the dryer resulting in damp and undry clothes ,, don't forget to check the outdorr vent and clear anything built up inside of that too

Your dryer has some internal ductwork. If it gets clogged, your dryer can't dry properly. In most dryers, to get to the internal ductwork to clear the clog, you have to substantially disassemble the dryer. A quick way to check for internal clogs is to remove the lint filter and use a flashlight to inspect the inside of the duct. If it looks clogged and you can't clear it using your vacuum. Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance.

Make absolutely sure the venting is clear going outside.
But, sounds like the Motor overheating.

have your blower motor checked

Howdy: In back of the dryer is a thermostat (inside) that lint hangs to. If it reads too hot it should stop heating. If not working then blows breaker. Inspect please, we do not want a electric fire. Good luck - Doug

Check and make sure your exhaust vent is clean and clear of any blockage.

All the blend doors and vents are controlled by vauum. If you look in the rear firewall behind the brake master cylinder you will see a vacuum check valve with lines entering the cabin of the vehicle. The yellow colored ones are for your central locking,the green for a/c system, and red for your heater/water valve,clear for your source. Try isolating your vac. systems by unplugging lines and capping them off. Any leak in either system can adversly affect another system. So isolate your leak and then you will have to test your actuaters in the leaky system. If you unplug the red line and cap it off-the water will stop entering your heater core.

Problem common with blocked vent, need to check house vent...dryer has blown the thermal fuse. found behind the back panel small white fuse(usual two blue wires)....clear the vent and replaced the fuse. run on air dry first to check vent, should feel close to a hair dryer on low.

Your dryer lint vent pipe out the back of the machine or maybe out the side is partially plugged. You have to pull the machine out and clear that pipe or rebuild it out to a soffit vent or static vent if it is in the attic, or out through your crawl space. This will make a huge difference. If that hot air and moisture doesn't get out of the machine it just goes back into your clothes.
Good luck!!
