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 do I get the fault codes up on a Panasonic split air conditioning system CUE24FKR


14.2.2 To Make a Diagnosis1 Timer LED starts to blink and the unit automatically stops the operation.
2 Press the CHECK button on the remote control continuously for 5 seconds.
3 "- -" will be displayed on the remote control display.
Note: Display only for "- -" (No signal transmission, no receiving sound and no Power LED blinking)
4 Press the TIMER ? or ? button on the remote control. The code "H00" (no abnormality) will be displayed
and signal will be transmit to the main unit.
5 Each press of the button (? or ?) will increase error code
number and transmit error code signal to the main unit.
6 When the latest abnormality code on the main unit and
code transmitted from the remote control are matched,
Power LED will light up for 30 seconds and a "beep" sound
(continuously for 4 seconds) will be heard. If no codes are
matched, Power LED will light up for 0.5 seconds and no
sound will be heard.
7 The breakdown diagnosis mode will be canceled unless
pressing the CHECK button continuously for 5 seconds or
operating the unit for 30 seconds.
8 The LED will be off if the unit is turned off or the RESET
button on the main unit is pressed.

Note:
"O" - Frequency measured and fan speed fixed.
The memory data of error code is erased when the power supply is cut off, or press the Auto Switch until "beep" sound heard following by pressing the "CHECK" button at remote controller.
Although operation forced to stop when abnormality detected, emergency operation is possible for certain errors (refer to Error Codes Table) by using remote controller or Auto Switch at indoor unit. However, the remote controller signal receiving sound is changed from one "beep" to four "beep" sounds.

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.

first check the compressor amps and the condenser fan rotation are correct if ok check power come to the compressor without interuption (from control in the indoor unit)if the remote setting are ok correct voltage to the compressor may high pressure stop it or low pressure compressure overheat.and if this was repeated many time the best to change the compressor.
