Relay in the Stinol refrigerator: where is it located, how to check and replace

Refrigerators Stinol are among the most reliable in the post-Soviet space, but even they are not immune from breakdowns. Most often, problems are associated with the start-up relay, which is responsible for starting the compressor and protecting against overloads. If your Stinol suddenly stops freezing, makes strange clicks, or doesn't turn on at all, this small but critical device may be the culprit.

Finding a relay in the refrigerator Stinol is not as difficult as it seems - if you know where to look. In this article we will analyze exact locations relays in different models (from Stinol 101 to Stinol 107), show photo of schematic placement, and also explain how to check its functionality without calling a technician. You will learn what tools are needed for replacement, how not to confuse a relay with a thermostat, and why sometimes the problem lies not in the relay itself, but in the compressor.

Important: if you have never dealt with electrical appliances, it is better to entrust the diagnosis to a professional. Working with high voltage requires caution - in Stinol refrigerators, the starting relay is under potentially dangerous voltage (up to 220V), even when the equipment is unplugged from the outlet.

1. What is a start-protection relay and why is it needed in a refrigerator

A start-up protection relay is an electromechanical devicethat performs two key functions:

• 🔹 Compressor start: when the refrigerator is turned on, the relay supplies current to the starting winding motor, helping it overcome inertia and start rotating.
• 🛡️ Overload protection: if the compressor overheats or consumes too much current (for example, due to jamming), the relay opens the circuit, preventing breakdown.

In refrigerators Stinol two types of relays are used:

1. Induction (electromechanical) - an outdated type, but still found in models before 2010 (for example, Stinol 102). It works on the basis of a coil and a magnetic core.
2. Electronic (posistor) - modern relays that are installed in Stinol 103/104/107 and newer. More compact, more reliable, but more sensitive to voltage surges.

Signs of a relay malfunction:

• 🔊 Refrigerator clicks, but does not start (attempts to start the compressor are heard, but the motor does not rotates).
• ❄️ The compressor works continuously (the relay does not turn it off when the desired temperature is reached).
• ⚡ The refrigerator knocks out the machine in the panel when turned on.
• 🔥 The relay body is melted or smells like burning.

⚠️ Attention: If the relay “shoots” (a loud bang is heard when trying to start), this is a sign turn-to-turn short circuit in the compressor. In this case, replacing the relay will not help - repair or replacement of the motor will be required.

2. Where is the relay located in the Stinol refrigerator: diagrams and photos

In 90% of Stinol models the relay is located directly on the compressor - in a plastic or metal case attached to the motor. However, there are nuances depending on the year of manufacture and modification:

To find the relay:

1. Unplug the refrigerator and wait 10 minutes (capacitors can retain charge).
2. Move the refrigerator away from the wall and remove rear protective panel (it is secured with latches or screws).
3. The compressor is a black metal cylinder with tubes. The relay is attached to it on the side or on top.
4. In modern models, the relay can be hidden under plastic cover with the inscription "Do not remove" - it must be carefully removed.

If you do not find the relay on the compressor, check:

• 🔌 Wires from thermostat —sometimes the relay is built into the control unit (rare, but found in Stinol 200 series).
• 📦 The back wall of the freezer —in some models the relay is hidden behind a foam panel.

3 How to check the relay of a Stinol refrigerator at home. conditions

Before replacing the relay make surethat this is where the problem is. To do this you will need multimeter (or at least an indicator screwdriver) Follow the step-by-step instructions:

Step 1. External inspection

Inspect the relay body for:

• 🔥 Scorched or blackened areas - a sign of overheating.
• 💧 Traces of rust or moisture - may indicate a short circuit.
• 🔌 Oxidized or burnt contacts - often the cause of unstable operation.

Step 2. Check with a multimeter

Switch the tester to resistance measurement mode (200 Ohms) and take measurements:

1. Connect the probes to contacts of the starting winding (usually they are labeled “S” or “Start”). be within 15–40 Ohm.
2. Check working winding ("M" or "Main") - resistance 5–15 Ohm.
3. Close the relay contacts with a jumper (for 1-2 seconds) - if the compressor starts, the relay is faulty.

Step 3. Checking the voltage

If the multimeter supports measuring alternating voltage (AC 250V):

1. Plug in the refrigerator.
2. Measure the voltage at relay input terminals - it should be 220–230V.
3. If there is voltage, but the compressor does not start, the relay does not operate.

⚠️ Attention: Do not hold the jumper on the relay contacts for more than 3 seconds! This can lead to overheating of the compressor windings and its failure.

4. How to remove and replace the relay in a Stinol refrigerator

If the diagnostics confirmed that the relay is faulty, it needs to be replaced. To do this you will need:

• 🔧 Phillips screwdriver (PH2).
• 🔌 Pliers with insulated handles.
• 📏 New relay (suitable model, see table below).
• 🧴 Alcohol or contact cleaner (for cleaning terminals).

Step-by-step instructions:

1. Unplug the refrigerator and discharge the capacitor (short-circuit its contacts with an insulated screwdriver).
2. Take a photo connecting the wires to the relay (so as not to be confused during reassembly).
3. Disconnect chip with wires from the relay (sometimes it is secured with a latch - carefully pry it screwdriver).
4. Unscrew relay mounting screws to the compressor (usually 1-2 screws).
5. Remove the old relay and install new aligning the contacts.
6. Connect the wires in exact sequence (focus on the photo).
7. Fix the relay with screws and turn on the refrigerator in network.

⚠️ Attention: In refrigerators Stinol with a system No Frost (models of the 200 series) there may be a relay built into the control unit. In this case, replacement requires soldering and it is better to entrust it to a specialist.

What to do if the new relay does not work?

If after replacing the relay the compressor still does not start, check:

- The wires are connected correctly (inverted phase/zero can block the start).

- Condition of the compressor (perhaps the piston is jammed or the winding is burned out).

- Voltage in the socket (at low voltage the relay may not operate).

- Integrity of the thermostat (if it does not gives a start signal, the relay will not turn on).

5. Common mistakes when replacing relays and how to avoid them

Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here are the most common:

• ⚡ Incorrect connection of wires —if you confuse the “starting” and “running” windings, the compressor will not start or will work in the opposite direction (found in older models).
• 🔧 Weak fixation of the relay —vibration from the compressor can loosen the contacts, which will lead to sparking and reflow.
• 🧹 Dirt on the contacts — oxidized or greasy terminals impair conductivity, causing the relay to heat up.
• 🔄 Using an incompatible relay —for example, installation RTK-X instead RTP-1 will lead to constant protection activations.

How to avoid errors:

• 📸 Take pictures initial connection of wires before removing the relay.
• 🧴 Clean the contacts alcohol or a special cleaner (for example, Kontakt 60).
• 🔍 Check the compatibility relay according to the table above or according to marking on the old device.
• 🔩 Tighten the screws fastening the relay with force, but without fanaticism (you can break the thread).

6. When the problem is not in the relay: other causes of the malfunction

If you replaced the relay, but the refrigerator Stinol still does not work, check:

• 🔋 Thermoregulator - if it does not give a start signal, the compressor will not turn on. Check with a multimeter (the resistance should change when you turn the knob).
• 🔌 Starting capacitor - in some models Stinol It is taken out separately and may fail (swelling or electrolyte leakage).
• ⚙️ Compressor - if it hums but does not start, it is possible piston jamming or a winding break. Check with an ohmmeter (the winding resistance should be. be 10–30 Ohm).
• 📡 Control unit —in modern models (Stinol 200 series), electronics can block startup due to sensor error.

How to distinguish a compressor malfunction from a relay breakdown:

If you suspect a compressor malfunction, do not try to repair it yourself this requires special equipment (vacuum pump, cylinder with freon) and skills.

FAQ: Frequently asked questions about the relay in the Stinol refrigerator

Is it possible to repair the relay or just replace it?

In most cases, the relay not being repaired is a one-time device. Exception: if the problem is in oxidized contacts, they can be cleaned with sandpaper and treated with alcohol. However, such repairs give a temporary effect (1-3 months).

Which brand of relay is best to buy for Stinol?

Reliable brands:

• DANFOSS —original relays for most models Stinol.
• LS (LSN series) —high-quality analogues, often cheaper than the original.
• ARD —a budget option, but check compatibility.

Avoid no-name relays without markings - they may not withstand the load.

What will happen if you do not replace the faulty relay?

If you ignore the breakdown:

• The compressor will be overheat and in the end will burn.
• Refrigerator stops freezing, food will spoil.
• They may melt wires or control board (in modern models).

Is it possible to temporarily start a refrigerator without a relay?

Yes, but highly not recommended for a long time. For temporary start:

1. Disconnect the refrigerator from the mains.
2. Remove the relay and close contacts "M" and "S" with a jumper (for example, a screwdriver with an insulated handle).
3. Plug in the refrigerator for 1-2 seconds - the compressor should start.
4. Remove the jumper immediately so as not to burn the windings!

This method is only suitable for emergency food preservation before replacing the relay.

Why does the new relay burn out after a few days?

Reasons:

• 🔌 Power surges on the network - install a stabilizer.
• ⚙️ Faulty compressor - it consumes increased current, and the relay is activated for protection.
• 🔥 Bad contact in the wires - check all connections.
• 🌡️ Refrigerator overheating (for example, standing next to the stove).
