E9: Outdoor IPM module fault

E9 means the outdoor IPM module is reporting a fault. The IPM is a power module on the outdoor control side. It is not a filter reminder and not a mode you can clear from the remote. Note E9, turn the breaker off for a few minutes, then turn it back on. If E9 returns, call support with the code and the model number. This repair is pro-only. Do not replace the outdoor board yourself and do not swap parts from another unit. A licensed HVAC technician should test the module. Keep the model number and the purchase date handy when you call.

What to do

1. 1Note the code, switch the unit off at the breaker for a few minutes, then switch it back on. If the code returns, call support with the code and your model number.

Sensor, board, fan motor and refrigerant repairs need a licensed HVAC technician. Have your model number and purchase date ready when you call.
