Norcold Power/ Circuit Board 628661 | New Style
This is the current Norcold power board being used in most Norcold refrigerators manufactured after 2006 and prior to 2019ish. Make sure that you see your Norcold model listed below before ordering. Your model number tag can be located inside the refrigerator on the right hand side.
This Norcold circuit board is the gateway for voltage getting to the various components of the refrigerator.
Below are the Norcold refrigerator models that this board fits: (If your refrigerator was manufactured in 2006 or newer, this could be the board that you need. Simply put, if your power board looks like the one above, then it is the one above because no other Norcold power board looks like this. If your refrigerator was manufactured Pre-2006, then this board will not fit your refrigerator, regardless of model number.)

Serial Number range will vary with the specific model refrigerator, however, if the board you have on your refrigerator looks like the board pictured above, IT IS! This style board has two plug connectors (one row of 10 pins and one row of 6 pins) while the older style boards are more rectangular and have only one 16 pin plug connector.

Both light flashing and wont work on propane but OK on 120V
Refrigerator wouldn't work on propane. It continued to try to ignite after the flame was present then a short while later after the clicking stopped, it would go back out. After this both light flash On and Gas. After this board was replaced everything return to normal

Refrigerator wouldn't work on propane. It continued to try to ignite after the flame was present then a short while later after the clicking stopped, it would go back out. They told me that this is what I needed and they were right. Working great now!
