Chigo inverter air conditioner shows P1, Chigo inverter air conditioner shows P

Chigo inverter air conditioner shows P1, indicating that the evaporator temperature protection of the air conditioner is faulty, if there is a system failure, please contact a professional for repair, you need to clean the evaporator or replace the indoor unit of the air conditioner.

When the indoor evaporator temperature exceeds 60, the air conditioner will trigger the evaporator temperature protection and turn off the compressor when the indoor evaporator temperature exceeds 60. When the temperature of the air conditioner drops below 48, the Chigo inverter air conditioner will return to normal working state and the compressor will be turned on again. However, due to the impact of temperature protection failure, Chigo inverter air conditioner will not be able to start.

It's not the 300V voltage of the inverter air conditioner.

The air conditioner shows that F1 is an open circuit in the indoor environment or a poor contact problem with the temperature sensor. Check the indoor temperature sensor bag and the indoor motherboard, and replace the indoor temperature sensor bag if the room temperature sensor bag is damaged; If it is a problem with the indoor motherboard, replace the indoor motherboard.

Meaning of Chigo inverter air conditioner f fault**:

1. F1 - communication failure of indoor and outdoor machines;

2. F2 - indoor ambient temperature sensor failure;

3. F3 - Failure of the temperature sensor of the indoor coil (including: inlet, pipe, and outlet);

4. F4 - indoor fan failure;

5. F5 - outdoor module failure;

6. F6 - outdoor ambient temperature sensor failure;

7. F7 - outdoor coil temperature sensor failure;

8. F8 - compressor suction (return) temperature sensor failure;

9. F9 - compressor exhaust temperature sensor failure;

10. FA - current and voltage transformer fault;

11. FC - abnormal failure of compressor drive;

12. FD - power supply phase sequence error or phase loss fault;

13. FE - abnormal failure of return air sensor;

14, ff - other faults;

15. FH - outdoor DC fan failure.

Hello dear, happy to answer your <>

Chigo inverter hang-up empty Wu did not adjust the P2 fault** is to detect the outdoor fan motor, there is a problem to replace; 2.The module is overheating. If the system is abnormal, clean the condenser or replace the external unit.

It is recommended to find the original professional cavity maintenance personnel to check it. Chigo Air Conditioner Fault **P2 means Low Voltage Overcurrent Protection. The possible causes and solutions are as follows:

1. The power supply voltage is lower than 187V, because the Chigo air conditioner is a wide power supply design, but if it is lower than this number, the air conditioner cannot be started. Solution: Solve it after installing a voltage regulator.

2. The internal filter screen and the condenser of the external unit are too dirty. Solution: Just wash it.

3. There is a problem with the starting capacitor or the compressor itself. Solution: You need to find a professional repairman to solve it.

Chigo air conditioner display P1 indicates that the indoor pipe temperature sensor is faulty.

The workaround is:

1. First of all, repair the fault** to determine that the machine shows that P1 is too high or too low voltage protection. The door-to-door measurement of the user's power supply voltage, the standby state is 225V, which meets the operation requirements of the air conditioner.

2. The multimeter detects the L, N terminal of the outdoor unit, the indoor motherboard has a 225V voltage output, when the measurement module P, N DC 300V input terminal finds that the DC bus voltage is unstable, the monitoring module P and N voltage repeatedly decreases from 300V, when it drops to less than 113V, the whole machine reports that the P1 voltage is too high or too low protection, and finally the module P and N voltage is 0.

3. After a few minutes, module P and N have a 300V DC input voltage.

The P1 fault of Chigo air conditioner is the voltage protection condition of the air conditioner, when the voltage of the air conditioner is too high or too low, the air conditioner will also show P1. The normal voltage of the air conditioner is 225V, and if the voltage is met, the air conditioner will not have a P1 fault** display.

The reason and the solution to the answer to the cover are as follows:

1. The display of P1 is due to the air conditioner's power supply voltage being too high or too low, resulting in the air conditioner reporting fault;

2. Check the fault** to determine that the machine shows that P1 is too high or too low voltage protection. Door-to-door measurement of the user's power supply voltage, the standby state is 225V, which meets the operation requirements of inverter air conditioner;

3. Use a multimeter to detect the L, N terminal of the outdoor unit, the indoor motherboard has a 225V voltage output, when measuring the P, N DC 300V input terminal of the measurement module, it is found that the voltage of the bus is unstable, and the voltage of the monitoring module P and N is repeatedly slowly reduced by 300V, and when it drops to less than 113V, the whole machine reports that the P1 voltage is too high or too low protection.

4. According to this phenomenon, it is preliminarily determined that the fault point is in the room.
