How does a timer reset work for defrosting a fridge?

When defrosting a fridge, a timer reset plays a crucial role in the process.

A timer reset works by regulating the length of time for which the defrost heater is activated. In a typical defrost cycle, the timer is set to initiate the defrost mode after a specific time interval, usually around 6 to 12 hours of continuous cooling operation.

Once the timer reaches its set time, it triggers the defrost heater to turn on. The heater provides heat to the freezer coils, causing any accumulated frost and ice to melt.

After a certain period, typically 20 to 30 minutes, the timer resets the defrost mode by deactivating the heater. This allows the temperature inside the fridge to rise slightly above freezing and prevents excessive melting of ice that may result in water leakage.

During the time when the defrost mode is off, the timer keeps track of the cooling time. Once the predetermined cooling time has elapsed, the timer resets and starts another cycle of defrosting.

Overall, a timer reset ensures that the defrosting process is carried out at regular intervals without causing any disruptions to the fridge's cooling functionality.
