How can you test to SEE if this is working? I have a bad control board, and I do diagnostic to start heater, but is there a way to tell that heater is working? Does this type get red hot or change visually at all? Does it make a sound?
Answer Rob, The easiest way to test this type defrost heater is a resistance reading, with the wires disconnected. Using a multimeter across the the terminals there should be a resistance of 21 to 27 ohms resistance. You can also check for 120 VAC from each termianl of the heater to chassis ground, with the control in a test mode or defrost cycle,and the defrost thermostat cold and a "closed" circuit. This will sldo confirm a faulty control board or thermostat. Also after the refrigerator has been in a defrost cycle for 5 to 7 minutes, you'd be able the "feel" the heat from the heater on the back of your hand.
How do I replace the heater on my side by side fridge model Kenmore 106.48212500? It's located behind the evaporate coils and seems impossible to get out.
Answer Hello Rose. You will need to remove the back wall and expose the evaporator coils. Then pull the bottom of the evaporator out of the back wall just enough to remove the heater. BE CAREFUL and do not break the lines of the evaporator. Then you will thread the new heater 2323197 into the evaporator.
