Here is the obstacle code of Hitachi air conditioner, hoping to help the majority of Hitachi air conditioner users! Hitachi KFR-25x2gw, BPMT displays the cause of the problem by flashing time /5 seconds of cold or thermal protection flashing /2 times of forced outdoor operation time flashing for 5 seconds /3 times of indoor and outdoor communication failure time flashing for 5 seconds /4 times of indoor and outdoor abnormal time flashing for 5 seconds/10 times of motherboard failure time flashing for 5 seconds in DC fan room/1/0 times of eepm data error/BPMT inverter cabinet air conditioner LD30/ Kloc-0/LD302LD303LD305 causes switch off overload (1) Switch off overload (2) Switch off (3) Note: delete the compressor lead and set the working mode. During normal operation, LD303 is on, indicating that the outdoor circuit is normal. Hitachi 5P air conditioner fault code 0 1: indoor protection device action, indoor substrate PCN 1, CN 16, CN20.02: outdoor protection device action, outdoor substrate PCN3, PCN4.03: abnormal signal (indoor/outdoor), indoor substrate CN2, outdoor substrate PCN65438. (generally short of freon) 1 1: abnormal suction thermistor, indoor substrate: THM3. 12: abnormal exhaust thermistor, indoor substrate: THM4. 13: abnormal antifreeze thermistor, indoor substrate: THM5.20: abnormal compressor exhaust thermistor. 22: environmental thermistor is abnormal, outdoor substrate THM2.24: outdoor pipeline temperature thermistor is abnormal, outdoor substrate THM 1.25: airflow control thermistor is abnormal, and outdoor substrate THM4.38: outdoor protection circuit is abnormal. 4 1: The cooling load is too large. 42: The heat load is too large.
Could you tell me the fault code of Hitachi air conditioning indicator?
Hitachi air conditioner fault code E 1 compressor high-voltage protection E2 indoor antifreeze protection E3 compressor low-voltage protection E4 compressor exhaust temperature protection E5 compressor overload protection E6 communication fault E0 indoor ambient temperature probe fault F 1 evaporator temperature probe F2 condenser temperature probe fault F3 outdoor temperature probe fault F4 exhaust temperature probe fault.
What does Hitachi central air conditioning fault code e, 00 mean?
It's the protection of the compressor. There is something wrong with the compressor outside the air conditioner.
Hitachi air conditioning fault code daquan
Hitachi air conditioner fault code A, cabinet machine KF (Rd)? Fault analysis: (Fault display: 1? 18 - 2 ? Why is the failure of 19 indicator always on, timing indicator flashing and temperature indicator flashing eliminated? The fault code is an external machine fault (insufficient refrigerant). Troubleshooting: (1) The problem of pipe temperature itself (pipe temperature resistance ω10k at 25℃) (2) Compressor failure: bad or compressor capacitance (3): Serious fluorine leakage (4) Pipeline system blockage caused by fluoride addition: It depends on the specific situation of the wall (5) Voltage problem: Due to overheating protection of low-pressure or high-pressure compressors (6 Why is the flicker fault solved? The fault code shows the internal loop temperature fault. Troubleshooting methods: ① indoor temperature break (resistance value is10kΩ at 25℃) ② main control board break 3. 1 1? Why is the flicker fault solved? The fault code indicates that there is a temperature fault in the pipeline. Check as follows: (1) Temperature damage of inner tube (resistance at 25℃ is10Ω), short circuit or open circuit (2) Why do you eliminate flicker fault caused by main control board damage? The fault code shows that the temperature of the outer tube is broken. It can be found that: ① the temperature of external pipeline is bad; ② Poor connector contact; ③ The main control board is broken; 5.8? Why is the flicker fault eliminated? The fault code is displayed as overvoltage protection. During the heating process, the following situations may occur: ① the temperature of the inner tube is damaged; ② The external fan is damaged or the fan capacitor is damaged; ③ The radiator of the internal evaporator is dirty or blocked; ④ The internal fan speed is low; ⑤ The circuit board is damaged by 6.7? Why is the flicker fault eliminated? The fault code indicates overheating inside the machine. Can be checked: ① the temperature in the pipe is not good; ② The internal motor is not good; ③ The radiator inside the evaporator is dirty and blocked; ④ The circuit board is not good; 7.6? Why is the flicker fault solved? The fault code is displayed as indoor icing (during cooling). It may be: ① the temperature in the pipe is not good; ② The internal motor is not good; ③ The radiator inside the evaporator is dirty and blocked; ④ The circuit board is not good; 8.4? Why is the flicker fault of 2 1 solved? The fault code indicates overheating. There may be: ① the temperature of the outer tube is not good; ② The external fan is not good; ③ The external heat sink is dirty and blocked; ④ The circuit board is not good; 9. The display is normal, and the cold and hot effects are not good. Why? It may be: ① the room area does not match the air conditioning type selection; ② Room heat dissipation; ③ Excessive or deficient freon; ④ Insufficient suction and exhaust pressure; ⑤ The fan air volume is small; ⑤ Others.
