This information consists of a summary of first-line field maintenance, which captures the logic of failure of the main hangers, cabinets, variant air-conditioning plants in guley, america, haile, tcl, chishu, and covers only the principles of equipment, the causes of failure, and the standardized overhauling process for both maintenance practitioners and the general household。
I. Underlying principles of air-conditioning failure
The majority of ac failures originate from sensor elements, circuits and refrigeration systems:
Temperature sensors: room temperature, dissociation of the tube detector from environmental aging resistance, which is the trigger for the failure of air conditioners, 25°c standard barrier of 5k, 10k, 15k, and parameter deviations that trigger self-protection of equipment
2. Internal and external communication malfunctions: fm connection line decorating, end oxidation, data transmission interruption pop failure code
3. System pressure anomaly: external heat dispersion congestion, cold-supplied imbalance, triggering high-pressure protection stoppages。
Mainstream hf failure + overhaul programme
Gream ac
1. E1 high-pressure protection: external condensers are ash-covered, refrigerated overfilled, high-pressure switches are damaged; overhauls are performed: electrical flushing of exterior wings is broken, all-time meter detection switches are broken and operation of measured refrigerant pressure。
2. E6 communication failure: failure of online lines, main panel communication elements; overhaul of the sub-routing line, distinguishing between liner or mainboard problems。
3. E8 evaporater's high temperature protection: insufficient filter congestion, deterioration of pipe-temperature probes, cleaning of filters, replacement of matching specifications sensors。
Beautiful fla
1. P1 voltage protection: in-house voltage fluctuations, faulty wires, damage to power plate components, priority measurement of municipal voltage
2. E5 overload protection: external wind failure, compressor casks, fluorine deficiency。
Hal air conditioning
E2 tube sensor failure: old spot short circuits that can be repaired by replacing fittings against the original plant's resistance value。
Self-check without code cold door failure
Winds are not cool: owners clean their own internal filters, and masters screen their external windmills and refrigerant stocks
2. Inner leaks: clogged and bent drains, tilted fuselage installed, drained and flattened
3. Frequent start-up: temperature control element parameters are abnormal and electricity is unstable。
Iv. Home maintenance free of charge (zero base operating, no machine dismantling)
1. Cleaning of filters before their use in alternate seasons to avoid evaporation engines freezing
2. Maintain 30 centimetres of ventilated space around the outer aircraft in order to eliminate miscellaneous objects
3. A short 15-minute monthly start-up of idle hours and maintenance of compressors。

I'd like a complete version of the full-text malfunction manual, acrobatFault codeCombination, focus on quick wrench, private mail keyword: air conditioner information, free access to complete PDF files。
Transmit this section to the maintenance team, the sub-district owners, and receive additional information on the central air conditioner, internal windpipe overhaul; invite friends to follow the account numbers and unlock the details of the parameters of the main frequency plate。
Following daily updates of refrigerators and dry maintenance at the laundry plant, attention is continuously being paid to regularly adding new in-house integration technical files. Follow-up public number wrench
Exoneration label
Dismantling involves high-voltage and cooling operations, and non-licensed professionals are requested not to demanage machines. The information is used only as a technical study reference, with some variations in the parameters of batching。
