Dryer turns itself off/on/off/onoff/on problem

I answered a service call. This stackable electric dryer had a tripped reset button. I pressed the red button. It started and ran okay. I let it run for awhile to make sure that the fuse didn’t blow again. It continued to run.

After a few minutes it shut off and then started again by itself; this repeats endlessly… on/off/on/off/on/off/etc/etc

Eventually, if the load is very small and very light the clothes will dry. There is warm air but not enough to dry a load of towels. I saw a similar off/on/off/on complaint posted elsewhere for this model but no solutions.

I can find no service information or wiring diagram anywhere.

Anybody fixed this problem? $200+ Control board? $15 Sensor?
What is it?

Sorry no one has gotten back to you sooner, but I think it is because none of us have experience on a Bosch. I certainly don’t

Hopefully my response will prompt an answer for you if someone is qualified to respond.

Good luck, and sorry you have not been helped.
