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.

Fixed my problem!
My refrigerator was working but not very well. At Norcold's site I found out what the resistance specs should be, tested it and found it to be low. Just used the refrigerator on a trip and it worked great. Just a little less resistance certainly made a big difference in cooling for me.

easy replacement
Got a replacement heating element for an old part no. 615627. New part is 621702. These appear to be physically identical. New part fit fine with a little jockeying around to get it in the sleeve. Fired up fridge and got it down to 20F in a couple of hours.
