Troubleshooting 

Potential problems that a new ac heater/ heating element could solve:

• N611 or N811 red light flashing three times
• N621 or N821 displaying an "n" code
• N641 or N841 displaying "ac he" code
• No cooling on AC mode
• Insufficient cooling on AC mode

Installation 

Time: 30 minutes or less

Tools:

• PB Blaster (optional)
• Rubber mallet (optional)
• Phillips head screwdriver
• Gloves

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.
• Slide new AC heater into the old slot and connect its wires in place of the old. 
• Once everything is connected, turn refrigerator on and plug it back in to verify that there is no AC heater fault displayed.
