The Panasonic air conditioner error H32 indicates a communication failure between the indoor and outdoor units, primarily due to an abnormality in the outdoor heat exchanger temperature sensor. This can cause the air conditioner to stop functioning, with the timer or error lamp blinking, and may prevent some indoor units in multi-split systems from operating. It is essential to address this issue promptly to restore normal operation.

Common Symptoms:

  • Air conditioner stops operation with timer or error lamp blinking
