The system has already determined that the thermistor is faulty so I wouldn't bother checking it as they are cheap and easy to obtain. The thermistor in question is one of two located at the right hand side of the indoor heat exchanger (the metal radiator-like assembly). One is the air temperature sensor and the other is the pipe/heat exchanger sensor. The air temp. thermistor is the one just in front of the heat exchanger held by a plastic clip. The pipe/heat exchanger sensor is the one that sits in a small metal tube near the copper pipes leading to the heat exchanger. It is usually a fairly tight fit because of a small metal insert to keep it in place. Use some small needle nose pliers on the metal insert to pull the thermistor out - NOT THE WIRES! Of course, make sure power to the A/C is completely off first.
You will probably have to replace both of the thermistors as they usually have the wires going to the same single plug on the controller board.

SOURCE: panasonic cs-pw9gke i need wiring diagram

Split A/C-Cold:

You need four wires(two #10 and two #12) to the outdoor unit, leaving you house, and three wires(#10) coming from the breaker to tye indoor unit inside your house.

Split A/C-Cold and Hot:

You need five wires(two #10 and three #12) to the outdoor unit, leaving your house, and thee wires(#10) coming from the breaker to your indoor unit inside your house.

This ypical arrangment(all of them use three wires fro the breaker), yet there are other units which may require 6-7 wires connected to the the outdoor unit depends on the added features to the unit.

SOURCE: Panasonic CS/CU-A242KR Air conditioner leaking water

OK lets see what we can help you with here. The condensate drain is clogged. There are a couple of ways to clear this clog so lets give it a try. If you know where the drain for the a/c is located outside (usually by the outside condenser unit) it will be a pipe that is just sticking out of the side of the house, if you find it take a wet/dry vac and place it on this pipe and turn the vacuum on and make a seal with your hand this should unclog the drain. If you don't find this pipe outside the house then go to the furnace and you will see at the bottom of the furnace a pipe (PVC) white, this is the drain for the unit inside. Take the wet/dry vac and have it at the ready in the event the clog is further down the line than at the furnace itself now the fittings on this pipe should not be glued together due to the ability to access for this very purpose. Take the pipe apart at one of the fittings and place the wet/dry vac on the end of the pipe towards the furnace and using your hand make a seal and evacuate the line. Do this to both sides since you don't know where the blockage is. If you are unable to separate the pipe at any fitting you will need to cut the pipe and at the spot of the cut you will need to repair it with a sleeve. Remember that the drain pipe is plastic and is made of pvc so you can get a repair coupling from any home improvement store for this repair.
Hope this helped you some

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.

PANASONIC CS-CU E24PKR fault code H00


H00 No abnormality detected - Normal operation

You may have a problem with the outdoor controller, the indoor controller or both. Power outages can do some strange things to the electronics. Turn the A/C isolator off for five minutes and back on again to be sure the problem is still there. You could also try this:

• To clear memorized error (Protective operation) status
after repair:
1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.

We have 2.0 HP inverter wall mounted LG aircon, when we turn on the ac, the indoor unit only is running and shut down after 3 mins. What is the solution?


Hi Marie, does the green indicator light on the front panel flash after it shuts down? If it does...count how many times it flashes this will refer to a fault code diagnostic.

Remote doesn't work on air con


Should be current detect pcb faulty, or compressor drawing too much current.
I don't have your model a/c, but panasonic fault codes stay pretty much the same
Normally panasonics have this info on the inside of the access panel.
Plus fault codes from the indoor unit make it easier to look up.

if the compressor is running, check the amps and refrig pressures.
