Tempstar ductless mini-split indoor unit shows F7 and outdoor fan does not operate correctly

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Failed DC fan motor, Faulty fan speed sensor (Hall effect), Loose fan motor connector, Faulty outdoor control board

Safety first: Turn OFF power at the outdoor disconnect.

Steps:

1. Inspect fan area: Ensure the fan blade is not obstructed and can spin freely by hand.
2. Check motor connector: Locate the multi-pin connector from the DC fan motor to the control board and ensure it is fully seated.
3. Visual inspection: Look for water intrusion or corrosion at the connector.
4. Restore power and test: If the fan still does not run and F7 returns, the motor or board likely needs replacement by a technician.
