E8 means the outdoor discharge temperature sensor is reporting a fault. Discharge temperature is a compressor-circuit reading, not the room temperature you set on the remote. The owner step published for this code is to record E8, switch power off at the breaker for a few minutes, and switch it back on. If the code returns, call support with E8 and your model number. The page marks the repair pro-only. Do not open the outdoor electrical box or unplug sensors on the compressor discharge line. That check belongs to a licensed HVAC technician.
