297216600 Defrost Thermostat ELECTRULUX

Technical specifications:

Compatibility: An original replacement part designed specifically for Electrolux, Frigidaire, and Kenmore refrigerators.

Material: Metal sensor (Bimetal) encased in a sealed, moisture-resistant plastic body, equipped with insulated connecting wires.

Performance: Acts as a sensitive thermal safety switch; It closes the melting heater's electrical circuit when the temperature drops to a certain level (to start melting), and opens it as soon as the temperature rises (to finish the process), protecting the cooling coils from overheating.

How to use:

Working mechanism: The thermostat is installed directly on the evaporator tube (Evaporator Coil). When ice accumulates and the temperature reaches the set point, the thermostat "tells" the melting timer (or control panel) that it is time to turn on the heater.

Employment: It is used as a direct alternative if the defrosting process fails; Damage to this part leads to a continuous accumulation of ice on the evaporator, which hinders the passage of cold air and leads to poor cooling in the refrigerator.

Important note: When examining this part, the "continuity" (Continuity) state must be confirmed using a multimeter while it is in a frozen state; If the device is at room temperature, the switch is usually open (does not give continuity), so it can only be thoroughly tested when it is very cold.
