How to carefully remove the cover from the relay of an Ariston refrigerator: instructions with photos and tips

Refrigerators Ariston are known for their reliability, but even they sometimes require intervention - be it replacing the relay, cleaning contacts or diagnosing faults. One of the first difficulties that users encounter when performing DIY repairs is removing the protective cover from the start relay. The procedure seems simple, but without knowing the nuances it is easy to damage the plastic latches, tear off the fasteners, or even get an electric shock.

In this article we will figure out how to properly dismantle the relay cover on refrigerators Ariston Hotpoint, Indesit (similar in design) and other popular models. You will learn what tools you will need, how to avoid common mistakes and what to do if the lid gets stuck or the latches are broken. And to make it easier for you, we have added step-by-step photos, video tips and relay compatibility table for different series of refrigerators.

We warn you right away: if you have never dealt with electrical appliances, it is better to entrust the work to a specialist. But if you are ready to act carefully, let's get started!

1. Preparation: tools and safety precautions

Before touching the relay be sure to unplug the refrigerator. Even if it is not working, the capacitors in the circuit can retain charge. Let the equipment stand for 10–15 minutes - this is enough for all the elements to discharge.

You will need:

• ✂️ Flat screwdriver (preferably with a thin blade, for example, for a watch)
• 🔧 Phillips screwdriver (size PH1 or PH2)
• 📸 Smartphone (to photograph the location of the wires before disconnecting)
• 🧲 Magnet (to hold small screws)
• 🧤 Rubber gloves (protection against accidental electric shock)

If the relay cover is held on by latches (and not by screws), also prepare plastic spatula or a mediator - they will help to carefully pry cover without damaging it. Metal tools are not suitable here: they can leave scratches or break fragile plastic.

⚠️ Attention: Some refrigerator models Ariston (for example, series MBA 2201 or HB 1801) have relays with seals manufacturer. Removing them may void the warranty. Check whether the warranty period is valid before starting work.

2. Where is the relay located in the Ariston refrigerator?

In most models Ariston the starting relay is located next to the compressor - at the bottom of the rear wall of the refrigerator. To get to it:

1. Move the refrigerator away from the wall (minimum distance - 50 cm).
2. Remove the bottom decorative panel (if there is one) - it is usually secured with latches or two screws.
3. You will see a black or gray plastic box (relay) attached to compressor.

On some models (for example, Ariston MRBF 2684), the relay may be hidden under the metal casing of the compressor. In this case, you will have to first unscrew the casing and then work on the relay.

What does the relay look like? This is a small box (about the size of a pack of cigarettes) with:

• 🔌 Two or three terminals for connecting wires
• 🔧 A screw or latch on the lid
• 🏷️ A sticker with marking (for example, DANFOSS 103N0240 or ARI 4-1)

How to distinguish the starting relay from the thermostat?

The thermostat is usually located inside the fridge compartment (behind the plastic panel) and connected to the light bulb. The relay is always located outside, next to the compressor and has a characteristic rectangular shape with terminals.

3. instructions: how to remove the relay cover

Now let's move on to the main thing. Depending on the type of fastening of the cover (screws or latches), the steps will be slightly different.

Method 1: Cover with screws

This is the simplest option you need:

1. Unscrew 1-2 screws on the relay cover (usually they are located in the corners).
2. Carefully lift the cover up - it should come off without effort.
3. If the cover “fits” tightly, slightly rock it from side to side.

Method 2: Cover with latches

Care is required here. Proceed as follows:

1. Insert a flat-head screwdriver or plastic spatula into the gap between the cover and the base of the relay.
2. Lightly press the first latch (you can usually hear a characteristic click).
3. Repeat the action on the opposite side.
4. Lift the lid, holding the latches depressed.

If the latches do not budge, do not use force you will break them. Try slightly heating the lid with a hairdryer. (temperature no higher than 50°C) so that the plastic becomes softer.

What what to do if the cover is “stuck”?

Sometimes due to overheating or prolonged use, the relay cover literally soldered to the base. In this case:

• 🔥 Gently warm up the joint. with a hairdryer (keep at a distance of 10–15 cm).
• 🧴 Apply a few drops WD-40 or alcohol into the gap between the lid and the body.
• ⏳ Wait 5-10 minutes and try removing the lid again.

⚠️ Attention: If the cover is cracked or deformed when removed, do not reuse it. Buy a new relay assembly - it will cost inexpensively (from 300 to 800 rubles depending on the model), but it is guaranteed to last longer.

4. Types of relays in Ariston refrigerators and their features.

Not all relays are the same. In refrigerators Ariston there are three main types:

If your relay is of the third type (sealed), Attempting to open it may damage the internal components. In this case, the only solution is to replace the relay assembly. The cost of a new relay for Ariston starts from 500 rubles (for example, ARI 4-1), but for electronic models the price can reach up to 2000 rubles.

Before purchasing a new relay, be sure to check its compatibility with your model of the old refrigerator. the relay must completely match the new one (down to the last digit!).

5. Common mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when working with relays. Here are the most common:

• ⚡ Power not turned off — can lead to electric shock or burnout of the relay board.
• 🔧 Lost screws —if you drop a screw inside the compressor, you will have to disassemble the entire unit.
• 📸 Unphotographed wires —without a wiring diagram it is easy to confuse the terminals.
• 🔨 Using inappropriate tools —for example, pliers instead of a screwdriver.
• 🧲 Use of a magnet near an electronic relay —may damage the microcircuits.

To avoid problems:

• 📝 Keep a record —fix the order of disconnecting the wires.
• 🕒 Take your time —it’s better to spend the extra 10 minutes before breaking the part.
• 🔍 Check the contacts if they are oxidized, clean them with alcohol or an eraser.

⚠️ Attention: If after removing the cover you see burn marks on the relay board, soot or swollen capacitors - do not turn on the refrigerator before replacing the relay. This is a sign of a short circuit, and restarting may damage the compressor.

6. What to do after removing the cover?

When the cover is finally off, you have several options depending on the purpose:

• 🔧 Cleaning the contacts — if the relay is unstable, wipe the terminals with alcohol or fine sandpaper (null).
• 🔄 Replacing the relay —if the part is burned out, install a new one, observing the polarity of the wires.
• 🔍 Diagnostics of the compressor —check the resistance of the windings with a multimeter (norm: 20–40 Ohms for the working winding).
• 📏 Checking the gaps —in mechanical relays, the gap between the contacts should be 0.5–1 mm.

If you are replacing a relay, pay attention to color marking of wiresB. refrigerators Ariston usually the following scheme is used:

• 🔴 Red - power (phase)
• 🔵 Blue - zero
• 🟢 Green/yellow —grounding
• ⚫ Black —output to compressor

After connecting a new one relay do not rush to close the lid. First turn on the refrigerator for 5-10 minutes and check:

• 🔊 Are there any extraneous sounds (clicks, hums).
• ❄️ Does the compressor start turn on the cold.
• 🌡️ Is the relay overheating (should be warm, but not hot).

1) Correct connection of the wires.

2) Serviceability of the socket (try another device).

3) Integrity of the fuse on the relay board (if any).-->

7. When is it better to call a specialist?

Not all breakdowns can be repaired yourself. Contact a specialist if:

• 🔥 The relay burns out again after replacement - this indicates problems with the compressor or electrical wiring.
• ⚡ The refrigerator produces an electric shock when you touch the body - a leak to the ground is possible.
• 🔊 The compressor is humming, but it doesn’t start - the starting capacitor may need to be replaced.
• 💥 If there is smoke coming from the relay or a burning smell is heard - this is a sign of a short circuit.

The cost of calling a technician in Moscow and the regions varies from 1,500 to 3,000 rubles (excluding spare parts). In service centers Ariston diagnosis will cost 1000–1500 rubles, but they provide a guarantee for the work.

If you decide to repair the refrigerator yourself, but something went wrong, do not continue experiments. It is better to spend money on a professional than to damage the compressor (replacing it will cost 8,000–15,000 rubles).

FAQ: Frequently asked questions about the Ariston refrigerator relay

Is it possible to remove the relay cover without disconnecting the refrigerator from network?

No! Even if the refrigerator is turned off with the button, dangerous voltage remains on the relay (up to 220V). Always remove the plug from the socket and wait 10-15 minutes for the capacitors to discharge.

How to understand that the relay has burned out?

Signs of a faulty relay:

• The refrigerator does not turn on, but the light inside is on.
• The compressor tries to start, but immediately turns off (clicks are heard).
• The relay heats up to a high temperature (you cannot hold your hand).
• There are traces of melting on the cover or terminals.

What is the difference between relays for Ariston and Indesit?

Many relays are interchangeable, since Ariston and Indesit belong to the same group of companies. For example, the relay ARI 4-1 is suitable for both brands. However, in electronic models (for example Ariston MRBF 2684 vs Indesit BIAA 13), the board firmware may differ. Always check the markings!

Is it possible to repair a relay with your own hands?

Mechanical relays (with a spring and contacts) can sometimes be repaired: you can clean the contacts, bend the spring, or replace a burnt resistor. But it is not practical to repair electronic relays with a board - it is easier and cheaper to buy a new one.

How much does a new relay cost for Ariston?

Relay prices in 2026:

• Mechanical (ARI 4-1, DANFOSS 103N) - 300–800 rub.
• Electronic (EVR 3, ARI 7-3) - 1200–2000 rub.
• Universal (for example, SEA 110) - 900–1500 rub.
