Thermostat for refrigerator Ariston, Indesit, Hotpoint (C00116193, 482000028874, Danfoss 077B6902)

Thermostat (temperature controller) is an essential component of the cooling system that maintains the optimal temperature in the refrigerator. This device functions as a thermal relay, automatically turning the compressor on and off depending on the temperature in the compartment. An important feature of the thermostat is its ability to regulate temperature in the range of -18 to -32°C, making it ideal for home refrigerators.

Main specifications:

• Type: thermostat
• Purpose: for refrigerators
• Voltage: 240-250 V
• Temperature range: -18...-32°C
• Capillary length: 1100 mm (±30 mm)
• Capillary diameter: 2 mm
• Connection: 2 terminals 6.3 mm + 1 terminal 6.3 mm (ground) + 1 terminal 4.8 mm (ground)
• Regulator shaft diameter: 6x4 mm (1 blade)
• Regulator shaft length: 11.5 mm
• Body dimensions: 51x31x30 mm
• Capillary material: aluminum
• Country of manufacture: Italy

Operating principle:

The thermostat controls the temperature in the refrigerator by responding to changes in pressure within a gas-filled capillary tube. When the temperature changes:

• When the temperature decreases, the pressure drops, and the compressor turns off.
• When the temperature increases, the pressure rises, activating the compressor.

The temperature is adjusted using the regulator knob, which alters the compression of the spring, affecting the gas pressure in the bellows.

How to choose the right thermostat:

When selecting a thermostat, pay attention to the following parameters:

• The type and model of your refrigerator.
• Power supply voltage (240-250 V).
• The temperature range supported by the thermostat.
• The length and diameter of the capillary.

For accurate selection, use the Ctrl+F key combination to search by your refrigerator model.

Possible causes of failure:

• Damage to the bellows housing, leading to pressure loss.
• Oxidation or burning of electrical contacts.
• Insufficient contact of the thermal bulb with the evaporator.

To prevent breakdowns, it is recommended to regularly check the thermostat for mechanical damage and maintain clean contacts.

Difficulty of thermostat replacement:

Replacing the thermostat is a fairly complex procedure that requires basic knowledge of electricity and mechanics. It is recommended to perform the replacement by following these steps:

1. Disconnect the refrigerator from the power supply.
2. Remove the panel covering the thermostat.
3. Disconnect the old thermostat, remembering the order of the wire connections.
4. Install the new thermostat, connecting the wires in reverse order.
5. Close the panel and reconnect the refrigerator to the power supply.

By following all instructions, the thermostat replacement can be completed in 30-60 minutes. If you lack experience in appliance repair, it is better to consult a professional.
