4. Service procedures

(2)Air conditioner does not operate

1Circuit breaker trips (or fuse blows).

(a)When the circuit breaker is set to ON, it is tripped soon.

There is a possibility of ground fault.

Check insulation resistance.

If resistance value is 1MΩ or less, it is a defect of insulation.
