HEATER W10857624

Hello Bill, Thank you for your inquiry. Before you can test your defrost heater, you must remove it from your refrigerator. A defrost heater is connected by two wires, and the wires are connected with slip-on connectors. Firmly grasp these connectors and pull them off the terminals. You may need a pair of needle-nosed pliers to help you. Do not pull on the wires themselves. Use your multi-meter to test the heater for continuity. Set your multi-meter to the Rx1 scale and place the tester's leads on one terminal each. This should produce a reading anywhere in between zero and infinity. We hope this helps.
