The compressor is the “heart” of the refrigerator, and sometimes to diagnose malfunctions or preventive cleaning it is necessary to remove its protective cover. However, incorrect actions can lead to damage to the sealed system, leakage of freon, or even a short circuit. This article will help you figure out how to remove the cover safely, what tools you will need and what to pay attention to when working with different types of refrigerators - from Soviet ZIL and "Minsk" to modern Samsung, LG or Indesit.
We will not convince you that the task is simple - it requires accuracy and understanding of the equipment. But if you are ready to follow the instructions, you can do it without calling a specialist. The main thing is take your time and follow the precautions that we will discuss below.
Preparation for work: tools and safety measures
Before you start dismantling, make sure that you have everything you need. Without the right tools, you risk stripping fasteners, damaging plastic parts, or causing injury. Here is the minimum set:
- ⚒️ Phillips screwdriver (usually PH2) - for most modern models.
- ⚒️ Flat screwdriver - may be needed to pry up latches or old screws.
- 🔧 Wrench (more often 8 or 10 mm) - for fastening the compressor to the frame.
- 📸 Smartphone or camera - to fix the location of parts before disassembly.
- 🧤 Rubber gloves - protection from sharp edges and possible residues oil.
Also prepare the work space: the refrigerator should be on a flat surface, and there should be enough space around it to maneuver. If the compressor is hot, let it cool for at least 30 minutes to avoid burns and deformation of the plastic during dismantling.
⚠️ Attention: If your refrigerator is connected to the system No Frost or has electronic control, before disassembling, be sure to unplug it and wait until it is completely defrosted (at least 12 hours). Otherwise, moisture may get on the contacts and cause corrosion.
Types of compressor covers: how to determine your model
Compressor covers differ depending on refrigerator brand, year of manufacture and compressor type (linear, inverter). Let's consider the main options:
| Refrigerator type | Lid material | Type fastenings | Features |
|---|---|---|---|
| Soviet (ZIL, Minsk, Biryusa) | Metal (steel) | Screws or bolts | Often rust, require WD-40 to unscrew |
| Modern budget (Indesit, Atlant) | Plastic | Latches + 1-2 screws | Can be fragile, easily broken when pressed hard |
| Premium (Samsung, LG, Liebert) | Plastic/metal | Hidden latches or magnets | Require special tools (for example, plastic blades) |
| Inverter compressors | Plastic with rubber seals | Combined (screws + latches) | Often have additional thermal insulation |
To accurately determine the type of cover, inspect the back wall of the refrigerator. If you see:
- 🔩 A metal plate with 4 screws - this is a classic version (for example, Stinol or Nord).
- 🔄 A plastic panel without visible fasteners - most likely latches (typically for Beko or Whirlpool).
- ⚡ The inscription “Inverter Compressor” —this means there is an inverter compressor inside, and the cover may have additional protection.
⚠️ Attention: Some models Samsung i LG the compressor cover is connected to the condenser (by the grill on the back wall). If you remove it, the air circulation may be disrupted - this will lead to overheating. Before dismantling, check if there is a sign on the cover “Do not remove.”
Step-by-step instructions: how to remove the cover from the compressor
Now let's move on to practice. Below is a universal instruction that is suitable for 80% of models. If your refrigerator has specific features, we will indicate them separately.
Disconnect the refrigerator from the power supply and let cool for 30 minutes|
Take a photo of the location of the lid and fasteners|
Prepare tools (screwdrivers, keys, gloves)|
Ensure good lighting (use a flashlight if necessary)-->
Step 1: Disconnection and defrosting
Unplug the refrigerator. No Frost, wait 12-24 hours for complete defrosting. For drip systems, 1-2 hours are enough. Make sure there is no condensation on the back wall - moisture may get on the compressor contacts.
Step 2: Removing the rear panel (if required)
For some models (Atlant, Pozis) the compressor is closed not only by its cover, but also by a common rear panel. To remove it:
- Unscrew the screws around the perimeter (usually 4-6 pieces).
- Carefully. pull the panel towards you - it can be held on by plastic latches.
- If the panel does not budge, check for hidden screws under stickers or rubber feet.
Step 3: Removing the compressor cover
Now we move on to the cover itself. The actions depend on the type. fastenings:
- 🔧 Screw fastening:
- Unscrew all the screws (usually 3-4 pieces).
- If the screws are rusty, use WD-40 or kerosene.
- Remove the cover by pulling it up and slightly yourself.
- 🔄 Latches:
- Take a plastic spatula or flat-head screwdriver.
- Carefully pry the cover on one side, then on the other.
- Do not use force - the plastic may crack!
- Pull the cover towards you with force.
- If it does not give in, check if there are additional screws under the rubber plugs.
- 🔌 Compressor (black or gray cylinder with tubes).
- 🔋 Start relay (small box with wires).
- 🔥 Capacitor (grid or coil).
- 🔌 Power not turned off: If you forget to remove the plug from the socket, you can get an electric shock when you touch the contacts. Always check that there is no voltage with a tester.
- 🔧 Frozen screws: If the fasteners are rusty, do not try to unscrew them by force - use penetrating lubricant and a ratchet wrench.
- 💥 Damage to the tubes: The compressor tubes are thin and bend easily. Do not lean on them or use them as a lever when removing the cover.
- 🔥 Compressor overheating: If you turn on the refrigerator immediately after assembly, the compressor may overheat. Wait 10–15 minutes for the oil to drain down.
Step 4: Inspect the compressor
After removing the cover you will see:
Do not touch the tubes and contacts - they may have residual voltage! oil. cleaning, use a soft brush or vacuum cleaner. If needed diagnostics — check the integrity of the wires and the absence of oil leaks.
Common mistakes and how to avoid them
Even experienced professionals sometimes make mistakes when working with a compressor. Here are the most common of them and ways to prevent them:
Another typical problem is loss of parts. For example, when removing the cover, rubber seals or small screws may fall out. To avoid this, use a magnetic tray or container for fasteners.
What to do if the cover cracks during removal?
If the plastic cover breaks, do not try to glue it with superglue - it will not withstand the vibrations of the compressor. It is better to order a new part (the article number is usually indicated on the cover itself) or make temporary protection from thin metal or plastic, securing it with ties.
Features for inverter compressors
Inverter compressors (Samsung Digital Inverter, LG Linear Compressor) have a more complex design. Their covers are often equipped with:
- 🔊 Additional noise insulation (foam rubber or rubber gaskets).
- 🔌 Electronic sensors (for example, thermocouples).
- 🛡️ Protective screens from dust and moisture.
- First, disconnect all sensor connectors (remember their location!).
- Do not pull the wires - they may come off the board.
- If the cover is secured with latches, use plastic spatulas to avoid damaging the seals.
When dismantling such covers:
⚠️ Attention: For inverter compressors Samsung series RB the cover can be glued around the perimeter. To remove it, carefully run a fishing line or thin wire along the seam, heating it with a hairdryer. Do not use a knife - you risk damaging the compressor winding.
When it is better not to remove the cover yourself
There are situations when disassembling the compressor at home is impractical or dangerous. Contact a technician if:
- ⚡ The refrigerator is under warranty (self-repair will void it).
- 🔥 The compressor gets very hot or turns off 5-10 minutes after starting.
- 💧 There is a puddle of oil under the refrigerator (a sign of depressurization system).
- 🔊 The compressor hums, but does not start (the start relay may need to be replaced).
- ❄️ The refrigerator does not freeze, but the compressor works (freon leak).
- Dust removal: Use a soft brush or vacuum cleaner with a narrow nozzle. Do not blow air under pressure - dust may get into the engine.
- Cleaning the capacitor: Walk over the grille with a damp cloth soaked in a soapy solution. For persistent contamination, use a special cleaner (for example, CRC Contact Cleaner).
- Checking the contacts: If there is oxidation on the relay terminals, clean them with fine sandpaper (600–800 grit).
- Lubricating moving parts: For fans (if any), use silicone lubricant. Do not use WD-40 or machine oil!
- Are all connectors connected (especially on the start relay).
- Are they damaged? wires.
- Has the thermal fuse tripped (if any).
- Cracks or chips in the plastic.
- Broken latches or fasteners.
- Deformation from heating (the lid has become "lost").
- Lack of seal edges.
- The compressor will heat up more.
- Dust will clog the condenser faster.
- The risk of moisture getting on the contacts increases.
It is also not recommended to remove the cover if you are not confident in your abilities. For example, for models Liebert or Haier the compressor can be integrated into a single unit with a condenser, and improper disassembly will lead to loss of refrigerant.
Cleaning and Maintenance After Removing the Cover
If you removed the cover for cleaning, follow these guidelines:
After cleaning, let all parts dry (at least 1 hour), then reassemble the refrigerator in the reverse order. Do not turn it on immediately - wait. 10-15 minutes so that the oil in the compressor is distributed evenly.
FAQ: Frequently asked questions about removing the compressor cover
Is it possible to remove the compressor cover if the refrigerator is running?
No. The compressor is under voltage, but the tubes are under high freon pressure. Turn off the refrigerator. from the mains and wait until the compressor stops completely (it must cool down).
What to do if, after removing the cover, the compressor does not start?
Check:
If everything is in order, but the compressor does not hum, the winding may have burned out. In this case, you need a technician.
How to understand that the compressor cover is damaged and needs to be replaced?
Symptoms:
If the cover does not fit tightly, the compressor will overheat. Replace it with an original one (the part number can be found in the instructions or on the manufacturer's website).
Does it need to be lubricated after cleaning?
No. The refrigerator compressor is a sealed system, and there is lubrication. it is not required inside. Oil is already filled by the manufacturer for the entire service life. You can lubricate only fans (if any) or moving parts condenser unit.
Is it possible to use a refrigerator without a compressor cover?
Short-term (for example, for diagnostics) - yes, but not longer than a day. Without a cover:
If the cover is broken, make temporary protection from available materials (for example, thin plastic).
