My mothers 800 Series drier shuts off after running for about 10 minutes. After it cools down it can be restarted, then shuts down again. It has two temperature sd swtiches on the air exhaust. Could one of these be bad causing the shutdown?

Not enough water VOLUME and pressure to supply the pump with a steady flow of water. Water is cavatating (adding air to the water) and the piston is heating up and jambing. Try using a larger size hose diameter and a shorter hose to supply the pump.

could be thermal overload in motor its a motor protector in the motor when the motor gets hot it cuts power to the motor when motor cools it closes and resets age of drier counts some times you can take drier apart and blow dust out of motor and will fix now if the door is not closing tight vibration can cause door switch to break contact that will do it too most of time motor or relay must be replaced

Your dryer motor has a thermal overload built in to it. If your symptom is shutting down allow to cool and it works again for a few minutes the shuts down again.

Hello,

Sorry to be the bearer of bad news but what your describing is a classis sign of a bad motor. When the motor is bad it will run will its cool...when it heats up it shuts off and will restart for a short time when colled off till once again hot and shuts off again.

does check engine light come on.check for fuel and spark when it doesnt start

Sounds like you may have a bad motor. If the motor is overheating it will shut down on its overload.

If its a shorted contact in the timer you could mark the spot where it stops and restart it again. It should stop exactly at that point.

after it has shut down check for gas at the fuel rail with the key on their should be gas squirting out constantly it sounds like the fuel pump is going out

Hi, I have a spare TU-PT700U that may be of use for you to solve your problem without having to replace your system.  My Panasonic onyx series monitor was stolen out of my house, but they left behind the TU-PT700U and cable.   If interested, respond to my craigslist post..

sounds like a tipical crankshaft position sensor will fix your car

based from your story, you are tiggering a thermal overheat protection device. as the device heats up, it would trip off the dryer, and comes back on again after a few minutes but as the heat increases, the device is being triggered faster until the device would no longer trips back because the dyer is so hot that it would take about 10 mins to cool down. i think this is just a secondary problem, your primary problem could be lack of air passing through the heating element. please check the stroller blade for dirt of flint and debri, check also the outlet duct, it could be clogged with flint also. i hope i was able to solve your problem.
