The Indesit No Frost refrigerator does not cool the upper chamber: 7 reasons and what to do

Have you noticed that in a two-chamber refrigerator Indesit No Frost the upper section has stopped cooling, but the freezer is working as usual? This is a common problem faced by owners of models Indesit C 132 G, Indesit DF 4180 W and other series with the system Full No Frost. Unlike drip refrigerators, where malfunctions are often associated with clogged drainage, here the root of the problem lies in the forced air circulation system or electronics.

In this article we will analyze 7 key reasonswhy the upper chamber may not cool - from banal freezing of the fan to failure of the control board. You will learn how to diagnose a breakdown based on indirect signs (for example, if the refrigerator makes a loud hum but does not freeze, the compressor is to blame in 80% of cases), and what measures you can take on your own without resorting to expensive repairs. For convenience, we have collected the symptoms in a table and added step-by-step instructions with photos.

1. Clogging of the No Frost system: why the fan does not blow cold air

The system No Frost in refrigerators Indesit works on the principle of forced circulation: the compressor cools the evaporator, and the fan evenly distributes the cold throughout the chambers. If the upper section does not cool, but the freezer is working, the first reason is freezing of the fan or clogged air ducts. This occurs due to:

• 🍂 Accumulation of dust and grease on the fan blades (especially if the refrigerator is located next to the stove).
• ❄️ Ice on the evaporator, which blocks the air flow (often due to a faulty heater defrosting).
• 🐭 Foreign objects (pieces of packaging, leaves) getting into the air ducts.

How to check? Unplug the refrigerator, defrost it for 10–12 hours, then turn it on again. If after defrosting the upper chamber starts working, the problem is freezing. If not, look for a clog or a malfunction of the fan.

2. Fan malfunction: how to hear the problem

The fan in the system No Frost is the “heart” of air circulation. If it breaks, the cold will stop flowing into the upper chamber, and the freezer will continue to work (since cooling comes directly from the evaporator). Signs of malfunction:

• 🔇 The refrigerator has become quieter than usual (the fan does not make noise).
• 🌡️ The temperature in the upper chamber has risen to +15°C and above, but in the freezer it has remained normal.
• 🔄 After defrosting, the problem is no longer present disappears.

To diagnose the fan:

1. Disconnect the refrigerator from the power supply.
2. Remove the back panel in the freezer (usually attached to 2-4 screws).
3. Check whether the fan blade rotates freely (does not touch ice or body).
4. Connect the refrigerator and listen: if the fan does not start, but voltage is applied to it (checked with a multimeter), it has burned out.

The cost of a new fan for Indesit is from 1,200 to 2,500 rubles. Replacement takes 20–30 minutes and does not require special tools.

3. Failure of the defrost heater: why ice forms

In the system No Frost the evaporator is responsible for defrosting heating element (defrost heating element). If it burns out, the evaporator becomes covered in ice, blocking air circulation. As a result:

• ❄️ A thick layer of ice (more than 1 cm) forms on the back wall of the freezer.
• 🔄 The refrigerator often turns on/off (the compressor runs non-stop).
• 📉 The temperature in the upper chamber rises, and in the freezer it drops below normal.

You can check the heating element with a multimeter:

1. Turn off the refrigerator and defrost it.
2. Remove the evaporator panel (usually hidden behind a plastic cover in the freezer).
3. Disconnect the terminals from the heating element and measure the resistance. The norm is 200–400 Ohms. If the device shows “1” (open circuit) or “0” (short circuit), the part is faulty.

What to do if the heating element is burned out?

If the defrost heater is faulty, it must be replaced. A temporary solution is to manually defrost the refrigerator every 2-3 days, but this will lead to increased wear on the compressor. The average cost of a heating element for Indesit is 800–1,500 rubles.

4. Problems with the compressor: when the refrigerator hums, but does not freeze

A compressor is a “pump” that pumps refrigerant through the system. If it does not work correctly, the cold is simply not produced. Signs of a compressor malfunction:

• 🔊 The refrigerator hums loudly, but does not cool (the compressor runs “idle”).
• 🔥 The compressor housing (the black cylinder at the back of the refrigerator) is hot to the touch.
• 🕒 The compressor turns on at 5–10 seconds and immediately turns off (protection is triggered).

The most common reasons:

It is not recommended to repair the compressor yourself - this requires special equipment (vacuum pump, pressure gauges). Contact the service center.

5. Control board malfunction: when the electronics go crazy

The control module (board) controls the operation of all refrigerator systems. If it fails, the following symptoms are possible:

• 📱 The display shows errors (for example, F04, F05 - problems with sensors).
• 🔄 The refrigerator turns on/off spontaneously.
• ❄️ The upper chamber does not cools, and the freezer operates normally.

Frequent causes of board failure:

• ⚡ Power surges in the network (if the refrigerator is not connected through a stabilizer).
• 💧 Moisture on the contacts (due to condensation or leakage).
• 🕰️ Natural wear and tear (board service life is 7–10 years).

Diagnostics:

1. Turn off the refrigerator for 10 minutes, then turn it on again. If the problem disappears, the failure is temporary.
2. Check the fuses on the board (they can blow out during a power surge).
3. Inspect the board for blackened or swollen elements (capacitors, resistors).

The cost of board repair is from 2,000 to 5,000 rubles. In some cases, it is cheaper to replace the entire module (the price of a new one is 3,500–6,000 rubles).

6. Capillary tube clogged: when freon does not circulate

The capillary tube is a thin channel through which the refrigerant enters the evaporator. If it becomes clogged (for example, due to moisture or oil), the circulation of freon is disrupted and the upper chamber stops cooling. Signs:

• 🧊 The freezer works, but weakly (temperature above -18°C).
• 🔧 The compressor works non-stop, but there is no cold.
• 🌡️ The condenser (grid at the back of the refrigerator) remains cold.

This malfunction cannot be eliminated on your own - professional cleaning of the system is required, replacing the filter-drier and refilling with freon. The average cost of repairs is 3,000–5,000 rubles.

7. Incorrect operation: errors that kill the refrigerator

Sometimes the problem lies not in the breakdown, but in improper use. This is what can lead to a lack of cooling in the upper chamber:

• 🚪 Frequent or prolonged opening of the door (especially in the heat).
• 📦 Overloading the refrigerator with food (air circulation is disrupted).
• 🌡️ Installing the refrigerator near heat sources (battery, stove).
• 🔌 Connection via an extension cord or unstable socket.

How to avoid problems:

• 🔹 Do not put hot foods in the refrigerator (let them cool to room temperature).
• 🔹 Regularly defrost the refrigerator (even if its does not close tightly, which will lead to freezing and overheating of the compressor. Level it by adjusting the front legs (the optimal tilt is 1-2° back). No Frost).
• 🔹 Check the rubber seals on the doors - they should fit snugly.

What to do if the refrigerator is not level?

If the refrigerator Indesit installed at an angle, the door may not close tightly, which will lead to freezing and overheating of the compressor. Level it by adjusting the front legs (the optimal tilt is 1-2° back).
