The reason why the air conditioner can't start running, and how it's handled
Reasons why air conditioners are not operational and how they are handled:
(i) reason analysis
The fuses in the dedicated circuits of ac1 were burned, or the power switch was in poor contact, or the power supply was missing. Currently, many users combine to use one power source, which is not normal due to the irregular operation of other appliances。
2 air conditioners use too low a power source to activate a cooler compressor in an air conditioner when the voltage is less than 10% of the single-phase normal voltage (220v), i. E. 198v or less。
Dials on the 3 temperature controller are not dialed to the appropriate position, e. G. To a higher position, when the power is attached, the temperature in the air-conditioning room does not reach the maximum temperature set (drive point temperature) and the compressor is not operational。
4 high pressure relays, such as too high condensing pressure, causing high pressure relays to stop the operation of compressors。
Low pressure relay actions, such as inadequate refrigerants in refrigeration systems, have led to low pressure on compressors to absorb gases, resulting in low pressure relays to stop the operation of compressors。
6 when the currents of compressors and fans are excessive, the excess protection relays are cut off by cutting the power。
(ii) method of exclusion
First, check the cause of the breakout of fuses inside and outside the air conditioner and make sure that measures to prevent further burnout are not adequate and should be adjusted and maintained in a timely manner. Households with air conditioners are advised to have dedicated power supply, which would largely prevent such failure。
If local power voltage is often in a low state, it should be used with a steady voltage of reliable quality, and households with larger household appliances should be advised to use dedicated power。
3. Transferring the dials from the temperature controller to the required slot, i. E., to the temperature required for the air-conditioning room。
The causes of the excess condensation pressure were examined and removed to restore the pressure to normal。
Examine the reasons for the refrigerant deficiency in the refrigeration system and remove it and restore its inhaling pressure to normal stress。
6 checks the reason for overloading of compressors and fans and excludes them; presses the double button to protect relays。
