LED1 of indoor mainboard is OFF.

Trouble shooting process:

1. Test the outdoor power supply (230VAC and +310VDC) with a multimeter. If 230VAC is available but 310DC not, the SPDU （ IPDU, HT ） module is damaged, replace it with a new one. If both 230VAC and 310DC are available, go forward to step 2.

2. Measure the voltage across Jumpers 1 and 4 of Terminal CN3 on the outdoor mainboard with a multimeter. If +12DC is not available, the SPDU （ IPDU, HT ） module is damaged, replace it with a new one. If +12VDC is available, go forward to step 3.

3. Within two minutes after the machine is supplied with power and turn on, measure the AC voltage between positions 1 and 3 on the terminal of outdoor unit with a multimeter. If the value varies between 0 and 80 VAC, the outdoor mainboard is damaged, replace it with a new one. If the value is constant at about 30V, the indoor mainboard is damaged, replace it with a new one.

Check the status of LED2 on the maindboard of outdoor unit and the running condition of outdoor unit within 3 minutes after startup.

Within 3 minutes after the machine is supplied with power and turned on with the remote controller, the outdoor unit stops shortly after startup, and the compressor will start up again 10 seconds after the machine stops. The above process repeats again and again.

1. The wiring of compressor is incorrect or the connection is poor;

2. The compressor is damaged

CASE1CASE1

At the stopped state, LED2 blinks （ 1Hz ） for several times, and after pause of 2 seconds or so, it blinks for the same times again.

LED2 blinking for 20 times indicates that the compressor might be damaged.

CASE2CASE2

LED2 blinking for 19 times indicates that Module SPDU might be damaged

Electrify the machine again and turn it on with the remote controller, then measure the temperature at the exhaust temperature sensor of the compressor on the outdoor unit.

If the temperature exceeds 115 ℃shortly after the machine starts up, the cryogen may have been leaked during installation, or there may be leakage in the piping system, or there may be other causes to make the exhaust temperature too high.

CASE1CASE1

Malfunctions occur after running for some time even though the measured temperature is below 115 .℃

Pull out the exhaust sensor and measure its resistance at standard temperatures. If the results deviate much from those in the resistance-temperature table, the sensor is damaged and needs replacing.

CASE2CASE2

Pull out the exhaust sensor and measure its resistance at standard temperatures. If the results do not deviate or deviate a little from those in the resistance-temperature table, the outdoor mainboard is damaged and needs replacing.

If malfunctions are reported before or upon the compressor being started up, Module SPDU is damaged and needs replacing.

CASE1CASE1

The compressor is started normally, but malfunctions are reported after it has run for some time.

If the power supply is in order, the system may have been over or under charged with gas, which can be judged through the pressure of the measuring system.

CASE2CASE2

Check the power supply. If the voltage is too low or too high, the machine is not damaged. It is the power supply that needs to be changed or improved.

CASE1CASE1

CASE2CASE2

With this malfunction, LED2 on the outdoor mainboard blinks 3 times at a frequency of 1Hz and an interval of about 2 seconds for 3 times.

If the wind temperature is below 50 and t℃he malfunction is reported after the machine has run for some time, check whether the sensor or the temperature monitoring circuit of the indoor mainboard is in order. See countermeasures for sensor troubles.

CASE1CASE1

If both the sensor and the temperature monitoring circuit of the indoor mainboard are in order, shoot the trouble as follows:

1. Check whether the indoor unit blows poorly due to blocked filters or poor condition of the fan. If yes, clean the filters or reinstall the fan. If not, go forward to Case 2.

2. Measure the pressure of the system. If the pressure is too high, the system is over charged with gas, otherwise go forward to Case 3.

3. Find other causes to make the temperature of coil pipes on the indoor unit too high and take according measures.

If the air conditioner is started normally, check whether the battery in the remote controller is powerless, whether the remote controller is damaged and whether the signal receiver works well

CASE1CASE1

If there is no response after the emergency button is pressed down, shoot the trouble as follows:

1. Check whether there is voltage of 230VAC between Positions 1 and 2 on the terminal of the indoor unit. If not, check the power supply and the damage of the power cables. If yes, go forward to Step 2.

2. Check the FUSE of the indoor mainboard. If burned out or broken, replace the fuse, or go forward to Step 3.

3. Check with a multimeter whether the voltage between the two ulterior positions on Terminal CN1-2 of the indoor mainboard is 10VAC ～ 14VAC. If no, the transformer needs replacing. If yes, the indoor mainboard might be damaged and needs replacing.
