Please Note: The process for changing a defrost heating element applies to all three styles of refrigerators. The three styles are, side by sides, top freezer mounts, and lowest freezer mounts.
The very first thing that you need to do before you begin your installation is to disconnect the power furnish to your appliance. Sometimes there can become a build up of frost on the evaporator panel. If this has occurred on your evaporator panel, you will need to defrost it first. The favorite method is with a hairdryer. Do Not use a heat gun. It will give off too much heat, and could warp and deform your plastic liner. Once you have defrosted it to the point that you can see the screws, you can stop defrosting.

The defrost bi-metal switch perceive is fulfilled, when it is cold, and open when it is warm. You will find the defrost bi-metal switch fastened to the top right, or left corner of the evaporator coil.
Now that you have settled the defrost bi-metal switch, now you need to search the wire ends or wire harness and unplug them. Set the Ohm/Voltage meter to Ohm. Attach one lead to each of the wire ends, to test the bi-metal switch. If the meter reads zero on a digital Voltage meter, or if the needle moves to the right on suitable Voltage meter, then your bi-metal switch is good. (If the bi-metal is still cold) If the meter reads one on a digital voltage meter, or the needle does not move on a suitable voltage meter, then the bi-metal switch is bad and it will need to be replaced.
Once you have completed testing the defrost bi-metal switch, put the evaporator panel back on and you also need to reinstall the icemaker(If applicable) You have completed the job!
