Daikin error code e7

Daikin error code e7

E7 indicates that the fan motor in the outdoor unit is not working properly. Particularly, this can be due to the fan’s speed dropping below the specified limit for 15 seconds or more, and there seems to be nothing to stop the fan motor from working properly.

There connection between the fan speed sensor and the main control board fails

Once the problem occurs for the fourth time, the system shuts down.

The most likely causes are:

  • Faulty fan motor
  • Lack of connection between fan motor and the PC board due to a loose or faulty connector
  • The fan has gotten stuck due to a foreign object or debris building up on it
  • In clearing condition, it normally operates for 5 minutes.
