Description
<p>A defrost heater is an electrical heating element used in refrigerators and freezers to prevent the buildup of ice and frost. Its primary uses are:</p> <p>1. Preventing frost and ice buildup: The defrost heater periodically activates to warm the evaporator coils, causing any accumulated frost or ice to melt and drain away. This helps maintain the efficient operation of the refrigeration system.</p> <P>2. Initiating the defrost cycle: The defrost heater works in conjunction with the refrigerator's control system to initiate the defrost cycle at regular intervals, usually every 6-12 hours. During this cycle, the compressor shuts off and the heater turns on to melt the ice.</p> <p>3. Improving temperature regulation: By preventing excessive frost buildup, the defrost heater helps maintain consistent and accurate temperature control within the refrigerator or freezer compartment.</p>
