Hello everyone, Lin Fei to answer the above questions, air conditioning maintenance code replication, air conditioning maintenance code many people do not know, now let's take a look!

Guangdong Zhigao Air conditioning Co., Ltd., founded in 1993, is headquartered in Nanhai District, Foshan City, an industrial town in the Pearl River Delta. Is a large modern enterprise group mainly engaged in the production and sales of domestic and commercial air conditioners. Therefore, today, Bian Xiao shares with you the fault code of Zhigao air conditioner, hoping to help friends in need.

Part one: some fault codes of household Zhigao air conditioners.

First, Chi Ko 285, 325, 388, 418 wall-mounted air conditioning fault code table:

Fault content running lamp LED1

Driving light timing light

The failure of the indoor coil temperature sensor flashes every 8 seconds.

The room temperature sensor fault flashes twice / lights up for 8 seconds.

The abnormal fault light of the outdoor unit is lit for 5 times / 8 seconds.

The indoor fan failure flashes 6 times / 8 seconds.

Once it is on, it turns on for 0.5 seconds and goes out for 0.5 seconds.

Only detected in standby state, showing indoor coil sensor failure and indoor temperature sensor failure.

If the indoor fan runs for 30 seconds without feedback signal, turn off the air conditioner and show the indoor fan failure.

two. Shigao crystal color series wall-mounted air conditioner fault code:

Including: 02, 16, 18, 19, 20.

Fault content digital tube display code description

Displays the on / off status of the room temperature sensor fault L2. If a failure occurs at the same time, the code L1 will be displayed and the room temperature will be displayed immediately after repair.

Failure of indoor coil temperature sensor

L1 indoor fan failure

When the L6 indoor fan is running, if there is no feedback signal within 30 seconds, turn off and display the L6.

Abnormal failure of outdoor unit

After E5 turns off the display "E5", the setting temperature is valid, but the digital tube does not display. You can restart the computer with the "emergency" or remote control "on / off" button, and the digital tube will show the room temperature.

Three. "Tian" series and well-off series hang up (51 and below 51) model fault code

Including: 25, 26, 42, 43, 45, 46, 47, 48, 50, 51, 52.

Therefore, the accessible traffic light LED1 states

The sensor flashes twice / 4 seconds at room temperature and displays when off.

The sensor flashes 3 times / 5 seconds and displays when off.

The outdoor unit flashes abnormally 4 times / 6 seconds, which is displayed when it is turned on or off.

No AC zero detection signal (PG only) flashes 6 times / 8 seconds and displays when the machine is turned off.

In a flash, it turns on for 0.5 seconds and turns off for 0.5 seconds. For example, 2 flashes / 4 seconds: 0.5 seconds on, 0.5 seconds off, 0.5 seconds on, 0.5 seconds off.

Stop for 2 seconds, a cycle lasts 4 seconds, and so on. For non-inverters, the following explanation for lamp flicker will not be repeated.

Note: no fan feedback, no AC zero detection signal, all indoor fan failures.
