Outdoor Fan Intermittent

Outdoor fan does not rotate or stops intermittently - Cooling capacity maintenance

Mitsubishi Electric · MSZ-AP Air Conditioners

What does Outdoor Fan Intermittent mean?

The outdoor unit's fan may not rotate even when the compressor is running, or it may start and stop frequently during operation.

Common Causes

  • When the outside temperature is low during cooling operation, the fan operates intermittently to maintain sufficient cooling capacity and prevent over-cooling.
