It's due to short of gas. Find leak and arrest and then charge gas.

Make sure your indoor blower is blowing, If not you have either a control problem or a bad blower motor.

I have a panasonic split system in the kids bedroom its an ECONAVI indoor unit is CS-E9NKR we have not used this A/C since last summer, now the compressor will not start, only the indoor unit operates


Typically on a mini split the outdoor unit is powered and the indoor unit gets its power from the outdoor unit. If the unit is a year old you might have lost your charge. Look at the connections at the indoor unit and outdoor unit. You will typically see oil or a dirty area on your copper were there is a leak.

I have an LG split system air conditioner model number LSZ244VN-4 it is coming up with a fault code of CS after it has been running for approx 5 minutes


There is no CS code. Please read as C5.
Fault Code 05 and 53 (CH05 is displayed at indoor unit, 53 is displayed at outdoor unit)
This fault code indicates a communication error between the indoor and outdoor units; this is usually caused
by wiring errors or condensate pumps connected to the inter-connecting cable.
The communication between the units is a fluctuating DC voltage commonly called a serial signal, it can be
easily lost if the wiring is not done correctly. If there is a communication error fault CH05 will appear within 5
mins of powering up the system.
Testing
• Check Outdoor and Indoor Power Supply Voltages ( 230V ±10% ) and correct as necessary.
• Check for any mis-wiring or loose connections and correct as required.
• Check the resistance between communication line and GND. (Normal: Over 2M).
• If one Indoor unit operates normally Outdoor PCB is generally normal.
Turn on the power and start the indoor unit in cooling, set the temperature to 18ºC; the serial communication
signal will only be present for the first 3 mins of operation.
Set your meter to DC Volts, Test between terminals 5 (Red probe) and 2 or Earth (Black probe) of the outdoor
unit, you should see a fluctuating 0-72 Vdc.
If the Voltage is not present disconnect the terminal 5 cable, test the Voltage between this wire (Red probe)
and 2 or Earth (Black probe), you should see a steady voltage in the range of -0.1 to -10.0 Vdc. If No Voltage
is present either the cable or Indoor PCB must be faulty. This can be determined by checking the voltage
output on the Comms terminal of the Indoor unit, with the Comms wire disconnected. If No Voltage is present
the Indoor PCB must be faulty, if present, cable must be at fault.

I have a Panasonic CS/CU-W18DKR - on cooling it works fine, auto aswell as fan, but on heating when it is on manual fan control it used to blow all the time, but not for some reason it only blows...


When the unit heats inside, the outdoor unit cools, and if the outdoor cooling coil gets too cold the system turns off indoor fan, and changes gas flow direction to de-ice the outdoor coil. Ensure both coils, and the filters are clean and if there is still a problem check system gas pressure for leaks.

How to wire up an E40 ceramic lamp holder for use with compact flurescent (sic) or high intensity discharge lights? (GENERAL ELECTRICAL KNOWLDEGE) Lights are used in factory High & Low Bay lighting;...


If this is being used as a socket for a 120-volt lamp (such as a compact fluorescent with self-contained ballast or an incandescent lamp), you wire the black (hot) AC line conductor to the brass-colored screw and the white (neutral) conductor to the silver-colored screw. If the socket is equipped with pigtails instead of screws, use pressure connectors (wirenuts) to connect black to black, white to white.

If you are using HID lamps, you don't wire directly to the AC line. These lamps must be used in a fixture with the correct ballast transformer, capacitor and ignitor (for pulse-start lamps) for the lamp wattage. If you are replacing the socket in such a fixture, follow the wiring of the old one when installing the new socket.

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.

Try to check the resistance of your room air and coil thermistor may be its out of range the reading of both thermistor is 8000 to 10000 ohms @ 25deg C temperature. if its higher or lower then the thermistor is out of range and need replacement. And try also to check your terminals and connector for loose.
