Hello. I'm focusedMaintenance of household electricityA dry-good-man's-man。
A lot of friendsCologne acI don't know what the code means. I don't know who to fix it. Today, the cologne home air conditioner + central air conditioner completes the whole malfunction code, the meaning of the malfunction, the maintenance method, and it's dry
I. Coron home air conditioningFault codeAnd maintenance resolution
E series failure code
E1
Impairment meaning: indoor ambient temperature sensor failure/percool protection
Possible causes: sensor short circuits, loose lines, dirty filters, fluorine deficiency
Maintenance methods: cleaning of filters; power outage restarts; inspection of sensor plugs; direct replacement of sensors with resistance abnormalities
E2
Fault meaning: indoor tube temperature sensor failure/heat overheating protection
Possible causes: pipe-temperature damage, internal muck, low wind volume, excessive refrigerant
Maintenance methods: cleaning of internal evaporation units; inspection of internal wind machines; replacement of pipe temperature sensors
E3
Fault meaning: outdoor ambient temperature sensor anomaly/system high pressure protection
Possible cause: outdoor detection failure, outloading, fan failure, too much refrigeration
Maintenance methods: cleaning of outer wings; inspection of wind turbines and electric appliances; replacement of sensors
E4
Fault meaning: compressor exhaust temperature overprotected
Possible causes: fluorine deficiency, external heat dispersion, exhaust sensor damage, four valves gas
Maintenance methods: leakage of fluorine; cleaning of exterior aircraft; replacement of exhaust temperature sensors
E5
Fault meaning: indoor and outdoor communication failure
Possible cause: loose connections, faults, break lines, end oxidation, damage to the main plate
Maintenance methods: re-plugging of communication lines; inspection of lines; replacement of main panels for remaining anomalies
E6
Fault meaning: outdoor disk sensor failure/module overheating protection
Possible cause: bad outside detection, heat spread, frequency module over hot
Maintenance methods: inspection of external sensors; cleaning of external aircraft; replacement of modules as necessary
E7
The meaning of failure: voltage abnormality protection/model conflict
Possible cause: excessive or low voltage, unstable power supply, compressor overload
Method of maintenance: measurement of voltage in normal range; inspection of power lines
E8
The meaning of failure: compressor overheating protection/high temperature protection
Possible causes: dissipation, loads, sensor anomalies
Maintenance methods: cleaning of internal and external machines; inspection of compressor temperature; replacement of main panel as necessary
E9
The meaning of failure: cold weather/frost protection
Note: normal working condition
Method of maintenance: no maintenance required, waiting for minutes of automatic recovery
E0 / er
Fault meaning: disconnection between display and main board
Maintenance methods: power outage restarts; line checks; still faulty change of main panel
F series frequency failure code
F0
Fluorinated systems, refrigerant leakage protection
Possible causes: fluorine leaks in pipes, loose connections, ageing seals
Method of maintenance: fluorinated vacuums filled with leaks
F1
The meaning of failure: ipm variable frequency module protection
Possible causes: module overflow, overheat, short circuits, reduction in compressor insulation
Maintenance methods: check compressor insulation; clean off-site; replace frequency module
F3
Fault meaning: compressor exhaust temperature sensor failure
Maintenance methods: inspection of detection lines; direct replacement of sensors
F4
Fault meaning: a direct parent voltage anomaly
Possible causes: power instability, module failure, compressor problems
Maintenance methods: power inspection; replacement of the frequency module
F5
The meaning of failure: freezing protection of indoor aircraft
Possible causes: filtration, low internal wind rate, fluorine deficiency
Maintenance methods: cleaning of filters; inspection of wind machines; replenishment of refrigerants
F6 / p6
Fault meaning: outdoor wind engine failure
Possible cause: wind engine failure, electrical damage
Method of maintenance: replacement of electric capacitor; inspection of electrical generators, replacement as necessary
P-series protection code
P1
Fault meaning: compressor overload, overflow protection
Possible causes: compressor casks, heat spread, current detection anomalies
Maintenance methods: cleaning of off-sites; measuring currents; compressors still in need of overhaul
P2
Fault meaning: refrigeration protection
Maintenance methods: cleaning of interior; inspection of wind; detection of fluorine
P3
The meaning of failure: heat overheating protection
Maintenance methods: cleaning of interior; checking of refrigerants; replacement of sensors
P4
Fault meaning: indoor tube temperature sensor failure
Maintenance methods: with e2 approach
Ii. Colon central air colon colon
E0: sensor abnormality. Device
E1: outdoor temperature sensor failure
E2: indoor tube sensor failure
E3: high pressure protection → check for high pressure switches, heat dispersion, refrigerant volumes
E4: system high pressure protection
E5: low pressure protection
E6: system pressure abnormalities → refrigeration system overhaul
E7: internal and external communication failure. Check the connection, main panel
E8: team overload protection. Check currents, heat spreads, wind machines
F1: variable module protection
F3: compressors run abnormally, professional compressors
F4: air exhaust sensor failure
F6: external ring temperature sensor failure
F8: external module communication failure check lines, change main panel
Iii. Generic rapid maintenance steps (new hands can also do)
1. Deactivation: 10 minutes before power is removed, and many misreporting can be eliminated
2. Prioritization of cleaning: cleaning of filters, internal evaporation units, outer wings
3. Screening of voltage: normal range 198 ~ 242 v for household use
4. Sensor failure: 10 k resistance value around 25°c, large deviation change
5. Communications malfunctions: focus on the looseness of connections, dermalization, reverses
6. Compressors/module type malfunctions: self-dismantling is not recommended and professional masters are sought
The above is the cologne air conditioning home + the whole cac failure code + the maintenance solvency, which is complete, and it is recommended that it be stored and that the air conditioning code be removed from search。
I'll keep updating all brands of air conditioners, refrigerators, washing machines, etc. Such as greeley, may, hale, hae-shin, coron, tcl. I'll fix it myself, i'll save money, i'll save my friends, i'll pay attention, i'll pay attention next time
