The flame on my Whirlpool dryer shuts off after a few minutes. The flame sensor shows continuity when it's cold and then registers infinity after it warms up. The flame then stays on for a few minutes then goes out. On the 2 lead gas valve coil the ohm reading is 1303. On the 3 lead coil the 2 outside leads read 580, the middle and the left read 1425 and the middle and right read 2000. Any help will be greatly appreciated.
