Part 5304521781 Defrost Thermostat
Purpose
Protects evaporator during defrost cycle.
Details
The 5304521781 defrost thermostat (also called a defrost limiter/safety) is a genuine OEM component used in select refrigerators from the Frigidaire/ Electrolux family. It monitors the evaporator temperature during the defrost cycle and opens the circuit when the set threshold is reached, preventing overheating of the evaporator assembly. If the defrost cycle fails, frost may build up on the evaporator, the freezer may cool poorly, or the defrost heater may stay energized. Replacing this part restores proper defrost control and helps maintain optimal performance and efficiency.
Included Items
One defrost thermostat/limiter assembly. Mounting clip or bracket may need reuse from original unit.
