1) SYMPTOM:
a. Motor over temperature.
2) SOLUTION:
a. Check the connection of the motor cable at the MCB (Figure A).
b. Use a multi-meter to check the motor wire circuit. Set the multi-meter to Ohms and place both terminals on the blue wires of the
motor cable (Figure B). There should be an Ohm reading of 0. If there is an Ohm reading above 0, replace the motor. If the Ohm reading is 0,
replace the MCB.
