Probably overheating. Check the outdoor coil and see if it is stopped up with dust, grass etc. If so, disconnect power to the unit, and clean the condenser coil with water or air. Be careful not to bend the fins if you use a water sprayer.

How to troubleshoot thermostat wiring?


I'm not sure if the thermostat is wired correctly. First, the thermostat is wired directly to the outdoor unit (compressor/condenser unit). It is NOT directly connected to the indoor unit. It connects to a low voltage control panel in the outdoor unit that sends a signal to your indoor fan/evaporator. This wire is called the fan relay switch and physically runs between the low voltage controls of the indoor and outdoor units. If the fan relay is bad it's possible that the unit runs continuously. To prevent destroying your outdoor unit there is a safety feature that prevents the indoor fan from shutting down while the outdoor unit is running. If the indoor fan did shut down while the outdoor unit was running than you would slug your compressor. That is, your compressor normally sees refrigerant gas but is instead seeing refrigerant liquid. That would not be good since this scenario would destroy your compressor. It sounds like a faulty fan relay. The actual contactor portion of the relay is in the outdoor unit.

The outdoor unit doesnt work for ac panasonic cs c9mkp,i have following the instruction on manual book.


After switching the indoor unit to cool, the indoor fan starts and the light flashes, lower the temperature setting to 16 degree centigrade. When the light stops flashing the outdoor fan and the compressor start, if not check the wiring connection going to the compressor contactor. Check if there is power supplying the holding coil of the contactor. If the contactor works, check the power on both contact points by using a volt meter. If the outdoor fan only works, you need to check line working pressure. If the standing pressure is low, compressor will not start.

Indoor fan slow to rotate in heat mode and no heat/compressor


The indoor fan will not run at normal fan speed untill the indoor coil reaches 32oC. This is done so that a cold draught is not felt when outdoor unit is not running. Check to make sure the outdoor unit is operating. If the outdoor fan is running but there is no indoor fan after 5 mins then you must likely have a gas issue or a fault compressor circuit.
