SOURCE: Error code E39 for Mitsubishi Heavy Industry Ceiling cassett type

E39 Fault is thermister, Mitsubishi way of saying im not going to start because there is something wrong. Generlly it is compressor fault or short of gas. Im guessing if you turned the power out. Waited twenty seconds, turn it back on. Now if you go to the outdoor part. Wait exactly 3 mins. If you hear the compressor try to start and fail then it would more then likely be your compressor if you dont hear anything and the unit faults out it will either be a board or short of gas.

Either way If the unit is under five years old get a warrenty agent out to look at it.

Sorry I couldnt tell you for sure but MHI are very vague when it comes to fault codes

SOURCE: LG split (3 indoor) LMU360CE

The LED #2 is only flashing while in disconnection or short in Thermistor (3 sec off / 0.5 sec on). If you want to change it, note: this is not an easy job to do! You will need to remove the top panel, then remove the control paneland then the front panel to gain access to the thermistor. The part isnot available to the public and requires an authorized service techfrom LG to take care of this problem. You will need a special tool toremove the front door seal spring clamp.
But you can call customer service @ 800 243 000 and see if theycan transfer you over to parts. Just give them the model and serial #and see if they would be willing to sell you the thermistor part. Youwill also need the door seal spring clamp removal tool to make the jobeasier.

SOURCE: U4 System transmission between indoor and outdoor units Daikin

Sounds like an interconnecting wiring error. Check wiring connection i.e. wires are connected in right order 1 to1 2 to 2 etc. from indoor terminal board to outdoor terminal board. Also check for slack or loose connections.
Hope this helps I take the time to answer your question so please rate me

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.

A/C Unit SAMSUNG -Outdoor unit model= MH080FXCA 4A was connected to 3 indoor units:


It's possible you have a bad data wire on one of the systems. Swap the data wire or both if two with a different wire. (1&4--2&3) whatever. Whatever you do inside obviously do outside. Might have extra resistamce that is throwing the error but will be fine for a ground wire.Or do one system at a time, being sure to change your dip switch settings until you figure out the problem unit. Good Luck!!

I have a contractor that wants to install a 36000btu outdoor unit(model # mh080fxca4a) and two indoor 18000btu indoor units(model #mh052fnca). What would be the output of the outdoor unit? The contractor...


Yes it rated for a maximum out put of 36,000 btu (3 ton) with the right indoor fan coil units which based on the model numbers should give the 36,000 btu's combined when both fan coil units are on, otherwise 18,000 btu's (1.5 ton)per fan coil.

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.
