Genuine Samsung Fridge Freezer Stainless Steel Defrost Heater DA47-00247K Heating Tube

Short Description:

Introduction:Refrigerator Defrost Heater

A high temperature resistance wire is placed in the metal tube, and the crystalline magnesium oxide powder with good insulation and thermal conductivity is tightly filled in the gap, and the heat is transferred to the metal tube through the heating function of the heating wire, thereby heating up. It can be used as defrosting electronic components of refrigerator refrigeration equipment.

Function: refrigerator defrost


Supply Capacity:     300,000pcs/month

Product Structure

Stainless Steel Tube heating element uses steel pipe as heat carrier. Put heater wire component in Stainless Steel Tube to form different shape components.




Feature advantages:

The stainless steel cylinder is used, which is small in size, occupies less space, is easy to move, and has strong corrosion resistance. A thickened thermal insulation layer is used between the stainless steel inner tank and the stainless steel outer shell, which minimizes temperature loss, maintains temperature, and saves electricity.


Auto Defrost Problems

How It Fails:

Like any heating element, the defrost heater is also prone to failure. The heater could be physically damaged, such as if it suffered a hard impact. Or, it might be an electrical fault, where no power can flow through the heater.

How To Fix:

Unfortunately, a failed defrost heater cannot be repaired. Instead, it must be taken out and replaced. The heater will be located inside the fridge, towards the back. You’ll need to remove the back cover and any wire harnesses attached to it to access the heater.

Next, disconnect the heater’s electrical connectors and unmount the heater. The heater might be held in place by mounting screws or aluminium straps.

Remove the defrost heater, and replace it with the new one.

Mount it in place and reconnect its electrical connector in the same way as the old one.

Lastly, replace the back cover and wire harnesses that you removed in the beginning.
