What to do if Panasonic Air Conditioner won't turn on?
If your Panasonic Air Conditioner isn't turning on, consider these possibilities: * Check for a power outage or interruption. If there was a power failure, try pressing the power ON/OFF button on the remote controller. * Verify that the operation (power) button is on. If the breaker is off, turn it on. If the breaker has tripped, it's important to consult your dealer without attempting to turn it on yourself.
