When a refrigerator Indesit suddenly stops working, one of the first reasons is a burnt fuse. This small but critical element protects the electrical circuit from overloads and short circuits. However, finding it is not so easy: depending on the model the fuse can be located in different parts of the case, and sometimes it is not there at all in the usual sense (for example, in modern inverter models).
In this article we will look at where exactly to look for the fuse in refrigerators Indesit different series - from old Indesit C138 to new Indesit ITF 118. You will learn how to check it with a multimeter, how to replace it in an emergency, and when it is better not to take risks, but to call a specialist. And also why sometimes the problem lies not in the fuse, but in the thermostat or start-up relay.
Let us warn you right away: if you have never dealt with electricity, it is better not to take risks. Working with the network components of a refrigerator requires compliance with safety precautions - disconnect from the network, use insulated tools and protect against electric shock. But if you are ready to act carefully, our instructions will help you save on calling a specialist.
1. Types of fuses in Indesit refrigerators
In refrigerators Indesit two main types of fuses are used:
- 🔌 Mains fuse —located in the plug or at the power input. Protects against power surges in the network.
- ⚡ Thermal fuse - installed on the compressor or in the winding circuit. Triggers when overheated.
- 🛠️ Fuse link —built into the start-up relay (in older models). It is often confused with the relay itself.
It is important to understand that in Indesit refrigerators after 2018, the mains fuse may be missing its role is played by an electronic control unit with built-in protection. Instead, look for thermal fuse on the compressor (usually soldered to the terminals or hidden under the insulation).
In models with system No Frost (for example, Indesit ITF 118 W) additionally install a fuse on the fan circuit. It looks like a small glass flask with metal caps and is usually located next to the blower motor.
2. Where to look for the fuse: diagrams for different models
The location of the fuse depends on the year of manufacture and series of the refrigerator. Below are proven diagrams for popular models.
| Model Indesit | Fuse type | Location | Photo/signs |
|---|---|---|---|
| Indesit C138, C168 (until 2010) | Network (250V, 5A) | Inside the plug or on the input cable under the back cover | Ceramic cylinder with metal tips |
| Indesit BIAA 13, BIA 16 (2010–2015) | Thermal fuse (125°C) | On the compressor, under the insulating tube | Flat, soldered to the compressor terminals |
| Indesit ITF 118, ITF 120 (after 2015) | Electronic protection + thermal fuse | In the control unit or on start-up protection relay | Microcircuit or SMD element on the board |
| Indesit TLAA 10, TLA 16 (No Frost) | Fan fuse (3A) | Next to the blower motor, behind the back wall | Glass bulb with spring contacts |
If your model is not listed in the table, focus on the year of manufacture:
- 📅 Until 2010 — the fuse is almost always in the plug or on the cable.
- 📅 2010–2018 — look for the thermal fuse on the compressor (soldered to terminals
CandS). - 📅 After 2018 —the electronics have replaced the fuses, check the control unit.
⚠️ Attention: In refrigerators with electronic controls (display, touch buttons), the mains fuse can be replaced on varistor - it looks similar, but it works differently!
3. Step-by-step instructions: how to find and check the fuse
Before you start work be sure to unplug the refrigerator and wait until the capacitors are discharged (5-10 minutes). You will need:
- 🔧 Phillips and flat-head screwdrivers
- 📱 Flashlight (for illuminating the rear parts)
- 🔍 Multimeter (for checking the circuit)
- 🧤 Rubber gloves (for safety)
Next follow the algorithm:
- Remove the back cover refrigerator (it is attached to 4-6 screws in models). c No Frost the cover may be plastic - remove it carefully so as not to break the latches.
- Inspect the plug and cable:
How to disassemble the plug?
Unscrew the screw on the plug, remove the cover. The fuse (if any) will be inside, between the pins.
In older models it is hidden under the insulation at the base of the plug.
- Check the compressor:
- Find the black cylinder (compressor) in the lower part.
- Remove the protective cover from the terminals (it is plastic, secured with latches).
- Look for a small fuse soldered to the terminals
C(common) andS(starting).
- Set the resistance test mode (200 Ohms).
- Touch the fuse terminals with the probes. If it shows
0or a value close to zero - it is working. If1(break) - it burned out.
☑️ What to do if the fuse is blown
If the fuse is intact, but the refrigerator does not work, the problem may be in:
- 🔄 Start-up relay (often "sticks" or gets hot).
- 🌡️ Thermostat (check if power is reaching the compressor).
- ⚡ Electronic unit (in models with a display).
4. How to replace the fuse: step-by-step master class
If you find a burnt fuse, it needs to be replaced. Never use "bugs" (wires, foil) - this can lead to a fire! Buy a similar fuse in a radio parts store or order online (the rating is indicated on the case, for example, 5A 250V).
Replacement instructions:
- Unsolder the old fuse:
- Use a soldering iron with a power of 25-40 W.
- Heat the solder on the leads and carefully remove the part with tweezers.
- Do not overheat the board - hold the soldering iron for no longer than 3 seconds.
- Install a new one:
- Insert the fuse into the same holes.
- Fix it by slightly bending the leads.
- Solder, using a minimum of solder.
- Make sure that exposed contacts do not touch the housing.
- Close the compressor terminals with a protective casing.
After replacement, turn on the refrigerator and check:
- 🔊 Whether the compressor starts (you should hear a relay click and a hum).
- ❄️ Does it start the freezer compartment cools down (after 15–20 minutes).
⚠️ Attention: If the new fuse burns out immediately after switching on - in the circuit short circuit. Immediately turn off the refrigerator and check the compressor, relay and wiring!
5. Common mistakes when finding and replacing a fuse
Even experienced craftsmen sometimes make mistakes that lead to repeated breakdowns. Here's what you can't do:
- 🔥 Ignore the rating —a 3A fuse will not replace a 5A fuse, even if they are externally the same. This will lead to the circuit burning out.
- ⚡ Check the fuse for a spark - connecting under voltage without load may show false serviceability.
- 🛠️ Forgetting about the thermal fuse - if you replaced the mains one, but the compressor does not start, check thermal protection on it.
- 🔌 Do not check the plug and socket - sometimes the problem is in burnt contacts, not in the refrigerator.
Another common mistake is confuse a fuse with a varistor. A varistor (aka suppressor) protects against power surges and looks like a small blue or green disk. It is checked with a multimeter in resistance mode: a working varistor will show infinity, a faulty one will show zero or low resistance.
If after replacing the fuse the refrigerator works, but after a while it turns off again, the reasons may be deeper:
- 🔋 Weak voltage in the network (less than 200V) - the compressor cannot start.
- 🌡️ Faulty thermostat —gives false signals to shut down.
- 🔄 Stuck fan (in No Frost)—overheats system.
6. When to call a technician: signs of serious malfunctions
Not all breakdowns can be eliminated by replacing the fuse. If you observe the following symptoms, it is better to contact a specialist:
- 💥 The refrigerator is electrocuted - there is a problem in insulation or grounding.
- 🔥 It smells like burning - the compressor or control board could have burned out.
- ❄️ The compressor hums, but does not freeze —freon leak or clogged capillary tube.
- 📉 The display shows error (for example,
F05,E1) - malfunction of the electronic unit.
The cost of repairing a fuse at a service center is from 1,500 to 3,000 rubles (depending on the model). If the problem is in the compressor or electronics, the price can reach up to 10,000 rubles. Therefore, before calling a technician, try diagnose the breakdown yourself:
- Check whether the light inside the refrigerator is on (if yes, there is power).
- Listen to whether the relay clicks when turned on (if not, the problem is in the control circuit).
- Touch the compressor (it should be warm, but not hot).
⚠️ Attention: In refrigerators Indesit with a system Full No Frost (for example Indesit ITF 118 W), the fan fuse often fails due to icing blades. Before replacing, defrost the refrigerator for 12 hours!
7. Prevention: how to avoid burning a fuse
To make the fuse last longer, follow simple rules:
- 🔌 Use a voltage stabilizer - especially if your network has frequent surges.
- ❄️ Regularly defrost the refrigerator (even No Frost needs care once every six months).
- 🧹 Clean the rear grille from dust - overheating of the compressor leads to thermal protection.
- 🔧 Do not overload the refrigerator — Excessive load on the compressor will shorten the life of the fuse.
If the power goes out frequently in your area, install voltage control relay (for example, Zubr R116y). It will automatically turn off the refrigerator when there are surges above 250V or below 170V, preventing the fuse and compressor from burning out.
For models with electronic control (Indesit ITF 118, Indesit ITR 118) it is useful to check the contacts on the control board once a year. Oxidation or dust may cause false alarms. Clean the board with a brush and alcohol (do not use wet wipes!).
FAQ: Frequently asked questions about fuses in Indesit refrigerators
Is it possible to replace the fuse with a more powerful one (for example, 10A instead of 5A)?
No! This is extremely dangerous. The fuse is designed for a specific current, and if you install a more powerful one, it will not trip if overloaded, which can lead to a fire. Always use a fuse with the same rating as the original.
Indesit refrigerator does not turn on, but the light inside is on. What's the matter?
This means that power is supplied to the refrigerator, but the compressor circuit is open. Reasons:
- The fuse on the compressor or in the start-up relay has blown.
- The thermostat is faulty (does not give a start signal).
- The relay is broken - check if there is a click when turned on.
Start by checking the fuse with a multimeter.
How to check a fuse without a multimeter?
You can use a tester made from a light bulb and a battery:
- Take a 3.5V light bulb (for example, from a flashlight) and an AA battery.
- Connect the light bulb in series with the fuse to the battery.
- If the light bulb is on, the fuse is good, if not, it is burned out.
But this method is inaccurate and only works for low voltage fuses. It is not suitable for mains (220V)!
How much does a fuse for an Indesit refrigerator cost?
The price depends on the type:
- Mains fuse (5A, 250V) - 50–150 rubles.
- Thermal fuse (125°C) - 100–300 rubles.
- Fuse for No Frost (3A) - 200–400 rubles.
Buy in trusted stores (for example, Chip and Dip, RadioLotsman) or from official dealers Indesit.
Can a fuse burn out due to frequent power outages?
Yes, frequent power surges when turning on/off the light is one of the main reasons for fuses to burn out. It is especially dangerous if the refrigerator turns on at the moment of a surge (for example, during a sharp restoration of voltage after a shutdown).
Solution: use voltage control relay or source uninterruptible power supply (UPS) for the refrigerator.
