U. S. Air conditioning maintenance methods and common malfunctions
I. Electricity protection
1. Extract the wire from the main plate current sensor to observe if there is any further malfunction; if there is further malfunction, the main plate is malfunction。
Check if performance systems are dirty, compressors, performance systems。
Ii. Non-facility screening of primary chips and computer communications
1. Check the normal connection between electrical controls and computers。
2. Replacement of the indoor electrical control master plate。
Iii. Method of screening for low-temperature protection faults in the vacuum mode
1. Check if the sensor's own line group is decorated; replace it, if any。
2. Check the robustness of the connection between the sensor body and the electric control main plate and adjust if there are problems。
Iv. Indoor evaporation sensor temperature openings or short circuits, indoor room temperature sensors openings or short circuits, condenser sensors detection of abnormal malfunctions
1. Checks whether the sensor's own line is decorated or fractured; replaces it if any;
2. Check the robustness of the connection between the sensor body and the electric control main plate and adjust if there are problems。
V. Wind speed out of control
1. Check whether wind-wheel assembly has been loose or fatal; if so, adjust。
2. Check the robustness and reliability of the internal electrical winder; adjust if there are problems。
3. Acoustic a/c vent mode, if the wind machine is unable to move, detects the flow of voltage between the strong winder and the black line:
4. The ac turns on the wind mode if the wind works properly:
(1) detection of direct current voltage between one third of the winder feedback port:
1 no voltage output is judged to be the main plate failure。
When 2 has a voltage output, measure the voltage between two thirds of the winder feedback port:
A. If the voltage is measured at 5. 5 v, the failure of the main plate is judged。
B. If a voltage of 2. 5-3v is measured, it is interpreted as electrical failure。
Vi. Indoor evaporation unit high or low temperature protection failure screening methods
1. Check if the sensor's own line group is decorated; replace it, if any。
2. Check the robustness of the connection between the sensor body and the electric control main plate and adjust if there are problems。
Temperature
1. Check the reliability of the connection between the electrical temperature insurance and the electric control main plate and adjust if there are problems。
2. The temperature fuse is removed from the main plate and the main plate is then plugged into the main plate for short-linking, which is malfunctioning if the temperature fuse is protected by the air conditioner。

U. S. Air conditioning service - central air conditioning service, multi-line, water refrigerator 24-hour telephone maintenance (4o-878-6287) u. S. Electrical maintenance: air conditioning non-electricity, non-working, non-refrigeration, noise, water leaking, fault code, fault code, etc。
Common malfunctions of u. S. Air conditioners: non-refrigeration, smelly, other failure codes for air conditioners, such as codes: e1 outdoor communication failure e2 zero detection error e3 wind speed lost e4 temperature fuse protection e5 outdoor temperature sensor failure e6 indoor temperature sensor failure
The u. S. Air conditioners are always malfunctioning
1. Main panel failure of the air conditioning outdoors;
2. External communication problems of indoor aircraft;
3. Outdoor clashes between the out-of-house frequency module and power failures;
4. Outdoor fans have broken down and have been unable to provide normal electricity;
5. The circuit boards under the control of the interior aircraft were blown up;
6. Compressors for outdoor machines display overload protection;
7. Refrigeration systems are blocked;
Freon leaks within air conditioning;
9. Inadequate power supply and insufficient voltage, which prevents air conditioning from working;
The u. S. Electronics company is a technical service company that provides a variety of indoor air-conditioning, central air-conditioning ventilation system cleaning services and comprehensive solutions in such locations as writing buildings, hotels, entertainment sites, restaurants, malls, government offices, hospitals, schools, terminal buildings, railway stations, factories, power plants and houses。
