How does a defrost timer work on a walk in freezer?

Do all freezers have a defrost timer?

Not all models use electric timers. Some freezers use hot gas in the condenser instead, which is mostly found in commercial freezers. The hot gas heats the evaporator, defrosting it faster. New computerized freezers monitor the number of times the door is opened.

How often should a walk in cooler defrost?

What is the function of timer in fridge?

A refrigerator timer, also known as a defrost timer, is a device which is used to regulate the amount of frost in a refrigerator. It turns on periodically to allow frost in the fridge to melt so that a frost buildup does not occur. Most modern refrigerators use a timer to keep their frost levels relatively stable.
