Why my Mitsubishi Electric Air Conditioner does not run?
- R
  Richard WigginsSep 12, 2025
  If your Mitsubishi Electric Air Conditioner doesn't run, it could be due to a few reasons. First, there might be a power failure; in this case, press the [ON/OFF] button after the power is restored. Another possibility is that the power supply is turned OFF, so ensure it's ON. Also, check if the fuse in the power supply is gone and replace it if necessary. Finally, the earth leakage isolator might be gone, so put it back in.

Why is no cool or warm air coming from my Mitsubishi Electric Air Conditioner?

  Shannon EdwardsAug 25, 2025
  If cool or warm air isn't coming out of your Mitsubishi Electric Air Conditioner, it might be because the restart-preventing circuit is active for 3 minutes to protect the compressor. Wait for a while, as it can take up to 3 minutes for the compressor to start. Also, if the Fresh Master operation started during heating or defrosting, wait until the defrosting operation ends before heating begins.
