Question

A) Adaptive defrost timers
B) Digital defrost timers
C) Programmable defrost timers
D) Mechanical defrost timers

Answer 1

Defrost timers that are always counting down to the next defrost cycle and may perform unnecessary defrost operations are referred to as mechanical defrost timers.

Step-by-step explanation:

Defrost timers that are always counting down to the next defrost cycle and may perform unnecessary defrost operations are referred to as mechanical defrost timers. Unlike adaptive, digital, and programmable defrost timers, mechanical defrost timers do not have the ability to adapt to the actual need for defrosting. They follow a fixed schedule, which can lead to unnecessary defrost operations.
