Also shown as

On a single-zone system, E7 isn't expected. Check the manual and call a dealer if you see it.

Safety first: unplug the air conditioner (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix Gree E7

  1. Match the modes

    Set every indoor unit on the system to the same mode, all cooling or all heating, from each unit's remote.

  2. Agree on a plan in the house

    If one person keeps switching their room to heat while others cool, the code will keep returning. Pick one mode for the season.

When to call a technician

If E7 shows even when every indoor unit is on the same mode, have a dealer check the system setup.
