If rotating, go to step 4. 2. undefined: If not rotating, go to step 3. 3. undefined: Attempt to rotate the condenser fan by hand. If it feels sticky or binding, replace the fan motor. 4. undefined: Measure condenser fan supply voltage at CON4 pins 24–23 in Test Mode 1. Expected: 11.4–12.6 V. If out of range, replace the Main PCB. 5. undefined: Measure condenser fan feedback voltage at CON4 pins 22–23 in Test Mode 1. Expected: not 0 V or 5 V. If 0 or 5 V, replace the fan motor. 6. undefined: Measure condenser fan PWM voltage at CON4 pins 21–23 in Test Mode 1. Expected: not 0 V or 5 V.
