Category: Defrost Timers

Browse replacement defrost timers and defrost control components for frost-free fridges and freezers. The defrost system periodically melts ice build-up on the evaporator coils to maintain efficient cooling. When defrost components fail, ice accumulates on the coils, restricting airflow and causing the fridge to lose cooling performance.We carry defrost timers, defrost heaters, and defrost thermostats compatible with major fridge brands. Defrost timers are specified by their cycle timing and terminal configuration.A failed defrost system typically presents as excessive frost in the freezer, poor cooling in the fridge section, or water leaking inside the unit. Modern frost-free fridges use electronic defrost control via the main PCB, while older models use mechanical defrost timers.
