Mitsubishi Electric · Air Conditioning

What does Abnormality not recurring mean?

After setting up the 'Failure Mode Recall Function' by pressing OPERATION SELECT and TOO COOL buttons simultaneously, then RESET, if the left OPERATION INDICATOR lamp does not blink, it means the abnormal condition is not currently present or recurring. This makes it difficult to pinpoint the exact cause at that moment.

Common Causes

  • The original abnormal condition was transient or has resolved itself.
  • The abnormality is not currently active.
