Why does my Mitsubishi Electric PLA-M71EA2-ER.UK log check codes for non-reoccurring issues?
- J
  Jordan WrightAug 8, 2025
  If the trouble with your Mitsubishi Electric Air Conditioner is not reoccurring, but a check code has been logged, it might be due to temporary issues such as protection devices activating in the refrigerant circuit (including the compressor), poor wiring connections, or electrical noise. Here's what you should do: 1. Consider these temporary defects. Re-examine the symptoms, installation environment, refrigerant level, weather conditions when the issue occurred, and wiring. 2. After servicing, reset the check code logs and restart the unit. 3. Note that this could indicate that there is no abnormality in the electrical components, controller board, or remote controller.
