Stackable Kenmore dryer won't start. I checked continuity of thermal fuse (rear of drum) what looks like another smaller thermal fuse on back panel and were good. The thermostat (next to fan) measured 48 ohms. The door switch has 3 wires. I checked outer wires; it is open- when i push button it is closed. I went to check start button, only to find out it is a master board.

Is the reading on the thermostat what I should get, and if not, will that cause it to not start? Is there anything else to check? Is there a way to check master board? Any info will help. I'd prefer not to have to get a new board unless i'm sure that is it.
