Refrigerator does not work, does not cool, does not start or start in seconds and stops repairing skills。
First, plug in the refrigerator plug, open the fridge door and hear the refrigerator start, but only about 10 to 20 seconds will stop automatically。
It stopped automatically
Checks if the thermostat switch is normal and loose, and if the switch is particularly mild, it leads to abnormal temperature control or damage to the thermostat。
Check the thermostat
When the power is removed, when the refrigerator is out of power, and the back of the fridge is opened, it comes with a screwdriver。
Open the back
When the back covers open, you find a box at the top that's a drainage box, two screws fixed, which can be removed, space larger, easy to detect。
Compressor out
Drain
The largest is a compressor, which is accompanied by a starter and an overheating protection。
Launcher
Small black lids can be broken directly and must be checked for complete power outages before opening, must be carefully electrocuted and must remove power plugs。
Take off the lid
It is then used to reach the 200 slots, measure the plugs, connect the bottom of the plugs with a black and a red one, and test the normality of the resistance with two zero-fire plugs。
Volume plugin
Next two plugs
It is normally in 20 or 30 om, i. E., the compressor is coiled and can be measured or, if not shown, the compressor is damaged. If more than 20 europes are normal, of course it means that the lines are fine。
24 euros
It is possible to plug in the power supply to the 750 slot, and it is normal for the starter to have electricity, if around 220 volts。
It's working
Further check and remove the trigger below and the heat shield above。
Pull out the starter
Pull the heat shield
Check if it's good or bad. When it's removed, the power is plugged in, the starter is separated from the overheating protection, the universal watch is still at the 750-point of the communication booth, the red and black forms are connected to the starter and the overheating protection, to see if there's a voltage of around 220 volts, or if there's no connection。
The electricity is normal
When you pull the power, you break the starter line, and you find two holes in the starter, and you move it to the block 200, and the red and black tabs are inserted into two holes on the starter。
Launcher
Volume start
The table shows a normal range between 15 and 20 om. If it's too big or a few euros, it means it's broken。
Range normal
Thermal protections can be removed from the circuit, the table can be struck to the binary stage, the red and black graphs can be exposed to the plugins on the thermoprotect, and the sound of the graphs indicates a normal state of access, which, if not visible, is broken。
Heat protection
We've just measured the starter, and there's another way to detect it, to just pick up the starter and shake it, and if it makes a sound, the starter is defective or damaged。
Launcher
Overheating protections cannot be detected in this way, and their own sound is swayed. Next, is the volume compressor normal? The newly removed compressor plugs have three outlets, the top of which is the public end, and the bottom two needles are the starting and running end, respectively. The 200-storey block will be used to measure the start-up end and the public end, bearing in mind the appearance。
Start-up and public
Volume running end and public end, remember the table。
Operation and public
Again, the start-up end and the running-end table show that this amount is approximately equal to the sum of their tables, and the compressor is normal。
Start and run
We're going to check the thermostats in the fridge. First, the power is out, the light covers are out, the light bulbs are off
Pull the power
Lights and bulbs off
There's a snap, some screws in front, and if you can't find it, then it's either hidden, or it's just visible. The screwdriver pulls it out, inside it's hidden screws off
Open the mask
Unload the screws
You can turn it over slowly, pull the switch button down, there's a screw in it, take it off。
Pull down the time button
Unload the screws
If the knob is particularly loose, it means it's broken
Is the rotation particularly loose
Is the sensor head normal? Checking if the inside line is non-existent is also its replacement process。
The power was plugged in, the thermostat in the refrigerator was moved to the third to fourth gear, and the compressor was activated in a dozen seconds。
The hand-held compressor surface is hot and the side-spreader is cold, indicating a leak in the refrigerator, i. E., a leak in the inside of the tube, which is of no repair value and which is expensive to replace
Handheld compressor
The 2 touch compressor is cool, indicating that the heat protector next to the compressor has been burned, malfunctioned or can be taken off to measure whether it is good or bad。
Heat protector
The temperature of the compressor is non-refrigeration and can be measured below
Measuring starter
The 4 compressor is warm, and while the power is plugged in, open to measure the heat protection. If there is a voltage, it is normal and if there is no voltage, the thermostat in the refrigerator is damaged
The voltage is normal
Test the thermostat
This is the point where the refrigerator was shut down in seconds, the detonator was normal with a voltage thermal shield, and the voltage indicated that the thermostat inside was normal, indicating that the compressor was damaged and the compressor replaced。
If not replaced, it will be possible to detect the three needles above the compressor with a one-size-fits-all table and, as with the tests above, the start-up end and the operating end are equal to the (start-up and public-to-operate and public) end, if normal, proving that the compressor has not been damaged, i. E., the cask。
Compressor normal
7 compressor casks, with a piston inside the compressor, which can only be struck on the surface or around the compressor with a hammer at the same time as starting
Take the hammer
Knock on the compressor
When the number of blows is struck, the steel drums in it are re-introduced, at which point if the simultaneous compressor returns to normal working sound for about 20 minutes and the compressor becomes normal。

This is the solution for all failure detection repairs, whether for domestic or vehicle refrigerators, provided they have compressors. See the comment section on the question。
