Freeze-up protection
When the indoor unit heat exchanger temperature is below 32°F(0°C) during cooling operation.
Supposed
Causes
Operation halt due to clogged air filter of the indoor unit.
Operation halt due to dust accumulation on the indoor unit heat exchanger.
Operation halt due to short-circuit.
