What to do if Mitsubishi Electric CITY MULTI PEFY-AF1200CFMR-E Air Conditioner drain pump is not working?
- JJade Henderson MDAug 10, 2025
If your Mitsubishi Electric Air Conditioner's drain pump isn't working right, start by checking the drain pump mechanism itself to ensure it's functioning properly. Also, verify that water is draining correctly; a clogged drain pump or drain piping could be the issue. Inspect the float switch for normal operation and test its resistance in both the on and off positions. If these steps don't resolve the problem, the indoor unit control board might be faulty, specifically the drain pump drive circuit or float switch input circuit, and it may need replacement. Finally, check the solenoid valves on the indoor unit for leaks, especially if the other checks don't solve the issue.
