Norcold 1200 Control Panel & Interior Light

[Badger1]

I have a 2006 Itasca Ellipse with the Norcold 1200 4 door refrigerator. Recently something tripped the GFCI outlets in the rig. After this happened I noticed that the control panel on the refrigerator was "off". I pressed the On/Off button and the display remained dark. I opened the door and the interior light also remained off. I reset the breaker for the fridge and the problem remained. Next, I removed the exterior access panel and discovered that the refrigerator was running (on electric) but still no display or interior light.

Refering to the manual I discovered that the refrigerator uses AC & DC. DC is used for the control panel and interior light when running on gas or electric. I checked the 5 amp fuse on the circuit board and used a multimeter to confirm I was getting 12vdc at the board and also confirmed 120v on the AC side. My assumption at this point was a bad display module on the refrigerator. I purchased a replacement module ($250) and plugged it into the connector on the exterior of the fridge. Still no display or interior light yet the refrigerator is cooling and the ice maker is working.

Has anyone had a similar problem or idea on other fixes?

Remove optical control panel at front of refer.

Remove wire harness.

Measure voltage between White/Violet wire and White/red wire.No or low voltage proves control panel bad.(Back of refer.)

Try to reset the fridge as follows:

Reset procedure for Norcold refer

Access the rear of the fridge thru the vent cover outside and remove the circuit board cover. There will be a a 16 pin connector right in front of you.

Make a jumper about 4-5 inches long and insert 1 end in the # 15 pin location which is normally vacant (top row, second from left).
Touch other end to one of the three grounds at the bottom right corner of the board (white wire).

Hold for 10-15 seconds. You should hear a click as the control resets.

If the fridge does not cool down and go thru a full cooling cycle this could be an indication of other problems such as a faulty cooling unit. If that occurs you should take it in to be checked further.

OR

Takes a short length of wire ... I used 11 GA with both ends stripped, and each end wound up tightly into a point. One end goes in to a small hole in the control board (pin #15 on our case), and the other end goes to ground. Directions that I have are to hold it
there for seven to ten seconds, and that resets the control board.

Piece of cake.
