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。

Five auto repair methods commonly used by car maintenance staff
In auto maintenance, make no arbitrary judgement of the good or bad of any sensor or implementer, let alone replace it, many repairers read the fail code at the outset, but sometimes a small detail computer can also miss, or even fail-out, and, in short, you can try it in the following simple ways:IntuitiveIn case of failure, the power lines of the various sensors and implementers should first be checked, and most of the failures are generally du
