Motor Resistance
Disconnect power from the dryer.
Disconnect the J8 connecter from the board. Set your meter to resistance setting. Check resistance
between the BROWN wire on J8 and the RED wire on the J5 connecter. This will read LOWER THAN the lowest
resistance because it is a parallel circuit. Follow ohms law. 1/R1 + 1/R2 + 1/R3 = 1/RT
The START winding is 3.14 OHM. If that is open, you may not detect this easily because it will read the RUN
winding, 3.36 OHM. Resistances are very close. If both or the overload is open also it will read the BLOWER
motor winding 15 OHM. All resistances are approximate.
If reading open, possible idler switch
