Many owners of household appliances are faced with a situation where a puddle suddenly forms under the refrigerator, or an unpleasant burning smell appears in the back of the unit. Often the cause of these problems is an overfilled or misaligned condensate pan, which is located directly above the compressor motor. Water can drip onto a hot engine, causing the formation of steam and corrosion, which in the long run leads to the failure of expensive components.
Independent dismantling of this part does not require deep engineering knowledge, but requires compliance with safety rules and accuracy. Compressor tray performs the important function of collecting moisture generated during defrosting of the evaporator, and its incorrect installation may interfere with air circulation in the technical area. Before starting work, you must completely turn off the power to the refrigerator by unplugging the power cord from the outlet to eliminate the risk of electric shock.
In this article we will analyze in detail the process of removing, cleaning and reinstalling the tray, paying attention to the nuances of various designs of refrigeration units. You will learn what tools you will need, how to avoid damaging fragile plastic elements, and what to look for when inspecting a water drainage system. Proper maintenance of the technical area will extend the life of your refrigerator and prevent damage to the floor covering.
Design features and purpose of the tray
To effectively troubleshoot the problem, it is important to understand exactly how the moisture collection system in your refrigerator works. Evaporatorlocated inside or behind the back wall of the freezer, is covered during operation frost. The defrost mode is periodically activated, the ice melts, and the resulting water flows down the grooves to the back of the housing. It is there, in the lower technical niche, above the motor, that the receiving condenser tray is located.
The operating principle of this system is based on the natural evaporation of moisture. The compressor becomes very hot during operation, and this heat is transferred to a metal or plastic tray installed above it. Water entering the tray quickly evaporates without requiring manual intervention. However, if the system is clogged or the geometry of the installation is broken, the water does not have time to evaporate and overflows.
There are several types of tray designs, which depend on the model and manufacturer of the refrigerator:
- 🧊 Plastic removable trays —the most common option, which is a container made of heat-resistant plastic, which is simply inserted into the grooves.
- 🔩 Metal trays with fastening - often found in older models or industrial refrigerators, can be fixed with bolts or latches.
- 💧 Integrated systems - the tray can be part of the compressor casing or welded to the frame, which requires more complex dismantling.
⚠️ Attention: In some models of refrigerators Indesit and Ariston the tray can be fixed on guides, which over time become deformed due to high temperature. When dismantling, act without sudden jerks so as not to break the plastic.
Understanding the type of structure will help you choose the right dismantling tactics. If you are unsure of the type of fastening, it is better to first carry out a visual inspection with a magnifying glass or a flashlight without touching the parts. Often it is enough to simply highlight the niche to see the fixing elements.
Necessary tools and preparation of the workplace
High-quality preparation is the key to successful repairs and the absence of damage to surrounding objects. You don't need complex professional tools, but having the right tools will make the task much easier. The work will be carried out in a limited space, so it is important to organize access to the rear wall of the unit.
To carry out the work you will need the following set:
- 🔧 Screwdrivers - Phillips and flat (preferably with dielectric coating of the handles).
- 🧤 Protective gloves - rubber or thick fabric, etc. how there may be dust, rust and detergent residues in the niche.
- 🧼 Container for water and rags —for draining liquid from the tray and wiping the surface.
- 🔦 Flashlight —for illuminating a darkened technical niche.
Before removing the tray, you need to move the refrigerator away from the wall. Make sure the floor under the feet is dry to prevent the unit from slipping. If the refrigerator is built-in, you will need to unscrew the fasteners securing it in the furniture niche and carefully pull out the body. Access to the rear panel must be free from all sides.
Be sure to wait until the compressor has completely cooled down if the refrigerator has just been running. The temperature of metal parts can reach 60-70 degrees Celsius, and accidental contact can cause burns. Also check that the drainage hose is not strained and does not interfere with access to the motor area.
Step-by-step instructions for dismantling the tray
The process of removing the tray may vary depending on the model, but the general algorithm of actions remains the same. The key is consistency and not trying too hard. If the part does not fit, it means that you have missed some kind of fixing element.
Perform the steps in the following order:
- Disconnect the refrigerator from the power supply and move it away from the wall at a convenient distance.
- Remove the back metal or cardboard panel covering the compressor. Usually it is attached to 4-6 screws or plastic latches.
- Visually assess the position of the tray. It can lie on top of the frame, hang on brackets or be inserted into the grooves of the casing.
- If there is water in the tray, carefully place the container and slightly tilt the pan to drain the liquid over the edge without splashing it onto the motor.
- Gently pull the tray towards you or up (depending on the type of fastening), releasing it from fasteners.
In some cases, especially in refrigerators Liebherr or Bosch, the tray may be blocked by the drainage tube. The tube is often inserted directly into the pan hole. In such a situation, you should not pull the tray with force. You must first carefully disconnect the tube by lightly squeezing the locking tabs or turning the connecting assembly.
If the tray is bolted, use a suitable screwdriver. Often, due to vibration, the thread can “stick”. In this case, treating with WD-40 or a similar rust solvent will help. Allow the compound to penetrate the thread for 5-10 minutes before unscrewing.

Cleaning and maintaining the drainage system
After you managed to remove the tray, you have the opportunity to conduct a complete audit of the system. Most often, problems with leaks are not associated with a breakdown, but with a banal blockage. The water draining from the chamber contains food particles, mold and mucus, which over time turn into a dense plug.
For proper cleaning, follow these steps:
- 🚿 Rinsing — rinse the tray thoroughly with warm water using a mild detergent. Use a brush to remove plaque from the bottom and corners.
- 🧼 Disinfection - treat the surface with a solution of soda or a weak solution of vinegar. This will kill bacteria and eliminate the unpleasant odor.
- 💨 Blowing out the drainage - check the drain hole in the tray and the drainage tube itself. If necessary, blow them out or clean them with soft wire.
Pay attention to the condition of the tube itself. If it is cracked or has lost its elasticity, it may be leaking water past the tray. In this case, it is better to replace it with a new one, choosing a similar diameter. Also check where the tube enters the tray - a leak often forms there due to a loose fit.
| Element | Symptom of malfunction | Remedy method |
|---|---|---|
| Tray | Cracks, chips | Replacement or repair with epoxy resin |
| Drainage tube | Clogging, petrification | Rinsing with hot water, cleaning brush |
| Fasteners | Rust, play | Replacement of fasteners, anti-corrosive treatment |
| Motor insulation | Wet insulation | Dry with a hairdryer, replace when wet |
Don't forget to clean the compressor itself from dust and cobwebs, using a dry brush or vacuum cleaner at minimum power. A clean motor works more efficiently and overheats less, which contributes to better evaporation of moisture from the tray.
What to do if the tray is cracked?
If the plastic tray is cracked, do not rush to buy a new one. For temporary or even permanent repairs, you can use food-grade epoxy resin or a special plastic sealant. Thoroughly degrease the surface around the crack, apply the compound and let dry according to the instructions. The main thing is to make sure that the material is safe and can withstand temperatures up to 80 degrees.
Typical mistakes and precautions
Even a simple operation to remove the tray can lead to complications if common mistakes are made. Beginners often underestimate the importance of the correct sequence of actions, which leads to breakdowns.
The most common mistakes when servicing this area:
- 🚫 Ignoring the power outage —working with electrical appliances without disconnecting from the network is strictly prohibited.
- 🚫 Use of force —if the tray cannot be removed, it means that the tube or latch is in the way. A jerk will cause the plastic to break.
- 🚫 Use of aggressive chemicals —strong solvents can corrode the plastic of the tray or damage the paint of the compressor.
⚠️ Attention: Never use sharp metal objects (knives, screwdrivers) for picking in the drainage hole or gaps of the tray. You could accidentally puncture the evaporator tube or damage the insulation on the wires, resulting in costly repairs.
It is also important to reinstall the tray correctly. It must stand strictly horizontally or with a minimal slope towards the drain (if provided for by the design). The distortion will cause water to overflow over the side to one side, ending up on the floor or on the frame of the refrigerator.
When installing, make sure that the drainage tube is inserted tightly and all the way. If the connection is leaky, water will drip past the tray, creating the illusion that the unit itself is leaking. Check the reliability of the fastening by slightly shaking the tray with your hand.
Assembling and checking the operation of the system
After cleaning and drying all elements, the assembly stage begins. Place the tray in its original place, making sure that it is securely fixed. If bolts were used, tighten them tightly, but not fanatically, so as not to strip the threads in the plastic bushings.
Connect the drain pipe. Make sure it is not twisted or kinked. Water should drain by gravity without obstacles. You can do a test by pouring a small amount of water (about 50-100 ml) into the drainage hole inside the refrigerator compartment and watching how it appears in the tray.
Install the rear protective panel and secure it. Plug in the refrigerator. During the first hours of operation, carefully watch the back wall. The absence of drops of water on the floor and dryness around the compressor will indicate the successful completion of the work.
It is recommended to carry out preventive cleaning of the tray and drainage system at least once a year. This will prevent the formation of traffic jams and the appearance of unpleasant odors. Regular maintenance is the best way to avoid sudden breakdowns.
Why can the tray be hot?
The tray is heated by the operating compressor, which is located directly below it. This is normal and necessary for condensation to evaporate. Temperatures can reach 50-60 degrees. However, if the tray is red-hot or smoke is coming from it, immediately turn off the refrigerator - this is a sign of overheating of the motor or a malfunction of the thermal relay.
Is it possible to operate the refrigerator without a tray?
For a short time - yes, but not recommended. Without a tray, water will drip directly onto the floor, creating puddles and increasing the humidity in the room. In addition, the absence of a tray can disrupt the air flow around the compressor, which will lead to its overheating and increased energy consumption.
How to understand that the tray is cracked?
If, after cleaning and proper installation, water continues to appear under the refrigerator, but the tray itself is visually intact, check its bottom for microcracks. They are often hidden under a layer of dirt. A dry and clean tray is easier to inspect using a flashlight.
Do you need to lubricate the tray fastenings?
There is no need to lubricate the fastenings if they are not rusty. In case of corrosion, you can use graphite lubricant, but avoid getting oil on the rubber tube seals, as oil can destroy the rubber.
