Advice 1: How to replace compressor in refrigerator

Unfortunately, the refrigerators sometimes break down. In some types of breakdowns there is a need to replace the compressor of the refrigeration unit. This type of repair requires specific professional knowledge and skills, and special equipment. So trust the replacement compressor should be only qualified staff of service enterprises.
How to replace compressor in refrigerator
You will need
  • - packing the valve;
  • - oxygen-propane torch;
  • tanks to the burner;
  • and measuring devices;
  • - a set of tools.
Instruction
1
Free refrigerator - remove all food, remove shelves and drawers. Unplug the refrigeration unit from the electrical network and expand it in such a way to get free access to its rear side. It was there, in a niche on the metal traverse is the compressor.
2
Lift the compressor. Carefully bend the tube and slide the compressor forward to see 5-7 For steel pipe is not broken, if it should proceed with the greatest caution.
3
Will nantokite filling up and remove the freon from the cooling system. For this it is necessary to pinch the capillary tube and turn on the compressor of the fridge for 3 minutes. During this time the freonpresent in the unit, percacets in the condenser. Take a special piercing valve and hook it up to the filter-dryer. Connect a hose to otvaloobrazovanija tank followed by a filter-drier by connecting the selection valve. Open the cylinder valve for 30 seconds and collect the freon. Close the device.
4
Solder in place of the filling tube is copper. The length of the copper tube should be 6 cm, diameter - 6 mm. Soldering parts of the refrigerator can be done with a soldering iron, or air-propane torch.
5
Make the incision into the capillary tube. The incision should be placed at a distance of 3-5 cm from the filter-dehydrator. Break off the tube at the incision. Unsolder the filter drier from condenser and remove it.
6
Desolder the compressor from the suction and discharge tubes. Clean the old solder tube of the refrigerator and install a plug.
7
Remove the plugs from the new compressor. Wire connections of the compressor with the tubing of the refrigeration unit. Install filter drier to condenser, and insert a capillary tube. Solder the compressor. Carefully inspect the soldering joints on all sides with a mirror. Make sure that soldering is produced evenly and not left neproblem.

Advice 2: How to check compressor on refrigerator

Fridge today is in every house, but, like every complex technical device, it can fail. The most common cause of failure – is a malfunction of the compressor. What can be signs of issues that occurred in the compressor how to diagnose and repair?
How to check compressor on refrigerator
Instruction
1
When the refrigerator heard noises and knocks. Check the suspension of the casing of the compressor by adjusting suspension bolts. If the cover relies on 2 – 3 springs, then install the bolts so that between the bottom bolt and the support remained a gap of 8 – 10 mm. If the cover rests on 4 springs, then adjust the position by moving the vertical brackets with springs. If your fridge is the internal suspension of the compressor, the repairs can be made only in a special workshop.
2
Increased consumption of electricity. If your kitchen is not 35-degree heat, next to your refrigerator, no heating and heating devices in network high voltage and the power consumption is clearly more than is required, then the faulty motor-compressor. Be breakage in this case can result from:
a) short circuits in the winding;
b) jamming of moving parts of the motor;
C) increased capacity of the compressor.
Unfortunately, these faults alone can not be repaired. For a more accurate diagnosis and repair of the refrigerator must be given to the workshop.
3
The lack of cooling. The main reasons for this failure, refrigerant leakage, blockage of zeolite cartridge, failure of the compressor. For more accurate diagnostics turn on the compressor and touch the discharge tube. If it heats up – leaking freon most likely not. Check out zeolite cartridge: when clogged it won't cool off. In order to completely verify the absence of leakage of freon, zoom to the inlet of the evaporator and listen – if there is a leak and freon in the capillary, there will be heard the characteristic sound of oil-air mixture. If extraneous sounds are not heard, the reason clearly in the compressor. This damage can only be addressed in the workshop.

Advice 3: How to connect a refrigerator compressor

If you need a compressor, you can take this device out of an old refrigerator and adapted to the case. In this case it is important to connect to provide such a compressorhave a long and stable work.
How to connect a refrigerator compressor
Instruction
1
Remove the compressor from the fridge. For this you may need to break the attachment. Then cut the tube (must be two of them) and the cable that connects to the temperature sensor. In this tester, measure the resistance of the cable and note the closed contacts, otherwise then it will be difficult to assemble a circuit. Removing the device, try to preserve the existing oil.
2
Turn on the compressorto make sure it is working. Check how it heats up and define the input and output. Further input will be possible to put a filter for cleaning air, and the output required install oil filter. For these purposes, you can take a simple car filter for fine purification of gasoline, which costs about 20 rubles.
3
Find regular serviceable relay. If you know the brand of the refrigerator, it is best to take relay from this device. Refer (if you got documentation on the fridge, the scheme can be viewed here: http://masterskie.info/elektroshema.htm) and connect it the same way as it was located on the fridge. In that case, if the winding in the engine is faulty, the relay will constantly disconnect the compressor and let it immediately burn.
4
Equip unit with a receiver. It can be easy to purchase, and you can do it yourself as follows: take an ordinary plastic bottle, twist the lid two holes and put in two pipes for input and output. Knead up some epoxy and pour it in a bottle. Close the bottle and flip it over. The resin is drained and permanently attach the cap with tubing to the bottle.
5
To connect the compressorand with the desired device, use the hoses for a washer that can be purchased in the shop.
6
Follow the oil level in the housing of the compressorand prevent it from overheating. Work time should not be more than 45 minutes.
7
Observe safety precautions when working with electrical appliances. Remember, all wires should be insulated, and all work can be done only with dry hands. No one can guarantee that a homemade compressor will run long and reliably, so it's easier to buy a device than to do it myself.
