My daughter's electric dryer won't run. It starts up & runs for about 1 minute before stopping. We have checked & cleaned out the ducts & filters, but no luck. My thought it may be one of the sensors, but not sure about how to check them. I would like to find a repair manual for this Bosch Dryer that would take me step by step as to what to check. I do have a volt-ohmeter & other tools. Thanks . . . Ray 1/9/2012
