I have a bosch propane dryer that will run however will not heat. The propane tank is 50% full and has not been recently filled. Our hot water heater works fine. The dryer is 3 + years old. Is there a safety switch or reset button that needs to be reset? IS there a intenal lint trap that is clogged. I am thinking there may be something clogged? How about a oxygen sensor in the unti?

Please help my wife is on my case big time??

Some helpful starting hints before I go home tonight would get me on track...

Thanks Brian J from Michigan
