NOTE: Motor must be cooled down for the test.
1. Check thermal device connector (yellow wires)
at control board.
2. Disconnect thermal device connector from control
board socket. Make sure contacts are clean and
secure.
3. Measure resistance of the thermal device. If reading
is not correct, replace motor.
Check Motor Thermal Switch: Unplug thermal
wires. Set meter to ohms. Meter should read the
proper resistance for each model (see table below).
4. Quick test for Ultras
