This error may be caused by an overheating or freezing of the heat exchanger, or high pressure control for heating and freeze-up protection for cooling. Usually, it is caused by a dirty air filter, a short circuit, or a problem with the temperature sensor in the heat exchanger. Also, if the indoor unit has a clogged air filter, it may be that the indoor unit has a short circuit or the thermistor in the heat exchanger is defective.
Normally, circuit breakers in molded-case equipment will trip if there are issues with the insulation around the equipment. So, before you restart the system, you should first check for any problems with the insulation. Resetting circuit breakers without first checking the insulation in the case may damage your equipment.
