As technology evolves, the type of household electricity becomes more abundant and, as far as air conditioning is concerned, the array, wall, frequency, intelligence, etc. Are fully functional。
However, after a long period of use, air conditioners have suffered minor malfunctions, and today they share common failures and maintenance methods。
Methodology/step
1. Compressor inoperable
Reason for failure: power failure
Method of exclusion: dismantling of malfunctions by universal-use watch and electronic pen. The fuse is broken, the fuse is replaced, and the wire is broken。
Reason for failure: power pressure is too low
Method of exclusion: measurement of voltage values on a single scale and, if necessary, power-pressure devices。
Causes of failure 3: loose or broken wire connections
Method of exclusion: inspection of wire connections, re-insulation of loose plugs, tightening of plugs, professional overhaul。
Wind machines are not operational
Reason for failure: poor contact with the main switch
Method of exclusion: the main switch contact point electrical resistance is measured on a universal scale and should be repaired or replaced when the resistance is too large or zero。
Fault cause 2: fan wire damage
Method of exclusion: replacement of fans with the same specifications and the same speed with a universal watch。
Causes of failure 3: loose bolts between wind engine electrics and wind leaves
Method of exclusion: tightened screws。
Causes of failure 4: break-down or short of fan capacitors road
Method of exclusion: inspection of capacitors and replacement of capacitors of the same specifications。
3. Compressor start and stop frequency
Reason for failure: inappropriate room temperature control
Method of exclusion: increase, as appropriate, the margin between indoor control temperature and primary temperature。
Reason for failure: over-temperature
Method of exclusion: improvement of the working environment, such as the installation of a fence, avoidance of sunlight, installation of air conditioners in a well-ventilated environment, etc。
Reason for failure 3: condensers are dirty
Method of exclusion: clean the condenser and remove the dust from the outer surface of the condenser。
4. Non-regulated heat-refrigeration function of hac
Reason for failure: electromagnetic switch to valve loop failure
Method of exclusion: the electro-magnetic membrane measure is used to convert to the valve wire, and if it is broken or burned, a new electro-magnetic valve of the same size should be replaced。
Reason for failure: failure of electrical heating unit
Method of exclusion: replacement of electro-heated silk or temperature protections of the same specifications with a universal watch check。
Causes of malfunction 3: temperature controller failure
Method of exclusion: the temperature controller of the same specification shall be replaced with a universal meter to check the thermostat, and if it is still ineffective after de-stereolysis of the contact point。
5. Leakage
Reason for failure: the horizontal tilt angle of window air conditioner installation is insufficient
Exclusion method: window air conditioners are re-installed in the correct manner。
Reason for failure: drain blockage
Method of exclusion: clean-up of congestion。
Reason for malfunction 3: inadequate level of interior installation
Method of exclusion: re-equipment of indoor aircraft using a horizontal device。
If you need to address specific problems (in particular in the fields of law, medicine, etc.) you are advised to consult professionals in the relevant fields in detail。
