Why does the fuse burn out in the Indesit No Frost refrigerator
The fuse in refrigerators Indesit is a weak link in the circuit, which intentionally destroyed during voltage surges or short circuits. Its task is to save more expensive components: the compressor, control board or fan motor. Common causes of combustion:
- ⚡ Power surges in the network (especially important for houses with old wiring).
- ❄️ Icing of the evaporator in the No Frost system - ice blocks the fan, the motor overheats.
- 🔌 Short circuit in the circuit of the compressor or defrost heating element.
- 🕒 Natural wear — fuses are designed for 5–7 years of operation.
In models Indesit No Frost the fuse most often burns out due to a faulty Defrost heating element (heater that melts the ice on the evaporator). If the refrigerator did not turn off for a long time before the breakdown or there was a thick layer of ice on the back wall of the freezer, this is precisely the problem.
Where is the fuse in the Indesit No Frost refrigerator
In refrigerators Indesit with a system No Frost The fuse is usually located in one of three places:
- On the control board (a small glass or ceramic cylinder with metal caps).
- Nearby with a compressor (in a metal or plastic case attached to the tube).
- In the power supply (for models with electronic control, for example, Indesit C132 NF).
To find it exactly, follow these steps:
Unplug the refrigerator|Remove the back cover (unscrew 4-6 screws)|Inspect the control board for cylindrical parts marked 250V|Check the compressor tube - the fuse may be in a black or white housing|Look for the inscription FUSE or the ~ symbol on the diagram-->
In most models Indesit No Frost (for example, T18 NF, B18 NF) the fuse is located on the control board at the top of the refrigerator. It looks like a glass tube with metal caps and markings 250V 5A or 250V 6.3A.
| Refrigerator model | Fuse location | Rating (A) |
|---|---|---|
| Indesit C132 NF | Control board (top part) | 5A |
| Indesit T18 NF | Next to the compressor (black case) | 6.3A |
| Indesit B18 NF | Power supply (behind the back cover) | 5A |
| Indesit ITF 118 | Control board (under the panel display) | 6.3A |
⚠️ Attention: In some models Indesit the fuse may be hidden under thermal insulation. If you cannot find it visually, use the diagram from the instructions for the refrigerator (section "Electrical diagram").
How to test the fuse with a multimeter: step by step instructions
Checking the fuse with a multimeter takes less than 5 minutes. You will need:
- 🔧 Multimeter (or tester) in continuity mode.
- 🔨 Flat-head screwdriver (for dismantling).
- 📸 Phone camera (to remember the location of the wires).
Action algorithm:
- Unplug the refrigerator unplug and wait 10 minutes (containers can retain charge).
- Remove the fuse:
- If it is on the board, carefully pry it off with a screwdriver.
- If it is in the case, unscrew the fasteners and disconnect the terminals.
- Set up the multimeter:
- Switch to continuity mode (diode or sound wave icon).
- Touch the probes to each other - a sound signal should be heard.
- Touch the metal fuse caps with the probes.
- There is a sound signal → the fuse is OK.
- No signal → the fuse is blown (open circuit).
If you don’t have a multimeter at hand, you can check the fuse visually: a burnt one usually has blackened or melted caps, and a broken thread is visible inside the glass tube.
How to replace a blown fuse in Indesit No Frost
If the fuse is blown, it cannot be restored (for example, by winding a wire instead of a thread) - this will lead to a fire or breakdown of the compressor. Replacement takes 10-15 minutes:
Buy a new fuse with the same rating (5A or 6.3A)|Disconnect the refrigerator from the mains|Take a photo of the location of the wires|Install a new fuse in the same connector|Check the operation of the refrigerator (the compressor should start in 5–10 minutes)-->
Where to buy a fuse:
- 🛒 In radio parts stores (cost - 20–50 rubles).
- 🛠️ In service centers Indesit (original, but more expensive - 200–400 rubles).
- 🌍 On AliExpress or eBay (if you need a few in reserve).
After replacement, turn on the refrigerator and check:
- 🔊 Whether the compressor starts (a hum should be heard).
- ❄️ Does the freezer start to freeze (after 1-2 hours).
- 💡 Do the indicators on the control panel light up.
⚠️ Attention: If the new fuse burns out immediately after replacement, the problem is not in it, but in short circuit (most often in the defrost heating element or compressor). In this case, it is required. professional diagnostics.
What to do if the refrigerator does not work after replacing the fuse
If replacing the fuse did not solve the problem, check:
- Defrost heating element:
- The resistance of a working heating element is 20–60 Ohm.
- If the multimeter shows ∞ (break) or 0 (short circuit), the part needs to be replaced.
- Thermostat or temperature sensor:
- In models Indesit No Frost the evaporator sensor often fails.
- Ring it: the resistance should change during cooling/heating.
- If the relay clicks, but the compressor does not start - the motor winding may have burned out.
Typical symptoms of other malfunctions:
| Symptom | Probable cause | Solution |
|---|---|---|
| The compressor hums, but does not start | The starting relay is faulty | Replacement of the relay (cost - 500–1000 rubles) |
| The refrigerator turns on for 5-10 seconds and turns off | Short circuit in the compressor winding | Replacing the compressor (expensive, it is often more profitable to buy a new refrigerator) |
| The freezer works, but the refrigerator does not no | Clogged capillary tube or leak of freon | Call a technician for refilling |
How to check the defrost heating element without a multimeter?
If you don’t have a tester at hand, you can check the defrosting heating element "on eye":
1. Turn off the refrigerator and defrost it.
2. Remove the back panel of the freezer (usually secured with 4 screws).
3. Inspect the heating element (thin tube with wires) - if it is swollen, blackened, or has traces of melting, it has burned out.
4. Also check if the wires are disconnected from the terminals of the heating element (a common problem after defrosting).
How to avoid re-burning the fuse
To make the fuse last longer, follow these tips: Indesit No Frost lasted longer, follow these tips:
- 🔌 Use a voltage stabilizer (especially if in your area frequent surges).
- ❄️ Defrost the refrigerator once every 6 months, even if the No Frost system - this will prevent icing of the evaporator.
- 🧊 Do not put hot food in the freezer - a sharp temperature change increases the load on the compressor.
- 🔧 Check the door seal —if it is worn out, the refrigerator operates in increased mode.
If the fuse burns regularly (once every 1–2 years), this sign hidden fault. Most often the culprit is:
- 🔥 defrost heating element (check its resistance).
- ⚡ Board control (there may be microcracks or burnt tracks).
- 🌀 No Frost fan (if it jams, the motor overheats).
FAQ: Frequently asked questions about fuses in Indesit No Frost
Is it possible to replace the fuse with a more powerful one (for example, 10A instead of 5A)?
No! This will lead to fire or breakdown of the compressor. The fuse must burn earlier, which will burn out expensive parts. Use only the original rating (indicated on the fuse body).
How to understand that it is the fuse that has blown and not something else?
Signs of a blown fuse:
- The refrigerator does not turn on completely (no light, the display does not work).
- The compressor does not start, but the relay clicks are heard.
- A blackened or broken fuse is visible on the control board.
If the light inside is on, but does not freeze - The problem is not in the fuse, but in the compressor, heating element or sensors.
How much does it cost to replace a fuse at a service center?
The cost of work in official services Indesit —from 1,500 to 3,000 rubles (plus the price of the fuse itself). If you do it yourself, you will only spend 20–50 rubles per part. However, if after replacement the fuse burns out again, you cannot do without a technician (diagnosis will cost 1000–2000 rubles).
Can the fuse burn out due to the fact that the refrigerator has not been defrosted for a long time?
Yes! In systems No Frost ice on the evaporator blocks the fan, the motor overheats, and the protection is triggered. If you do not defrost the refrigerator for years, the defrost heating element may fail and cause a short circuit that will burn the fuse. Defrost the refrigerator every 6 monthseven if the manufacturer claims that this is not necessary.
