Steps:

• Turn refrigerator off for several hours to let things cool down on and around the cooling unit
• Unplug refrigerator from the AC outlet in the back and turn refrigerator off from front control panel
• Remove power board cover
• Take a picture of the board before disconnecting AC wires
• AC heater wires are labeled AC HT HI and AC HT LO (both leads are interchangeable)
• Follow the wires over to the flu
• The AC Heating rod drops down into a slot on the flu that is buried within the insulation.
• Remove tin shroud that is holding insulation around the flu and locate the AC heater/ AC heating element
• If the AC heater does not slide out easily, you may need to use PB Blaster or Liquid Wrench to break up corrosion. Gently tap with a rubber mallet and it should come out just fine.
