So it looks like our Refrigerator has two A/C heater elements. Both of the wire sets look identical and both are labeled as 120 VAC heater elements. Both tested out with the ohm meter at about 73 ohms. So, I'm thinking the control board may have failed. Does anyone know of testing instructions for a board with a part number of 621271?
Thanks for the help!

Did you check the AC fuse on control board?
If you have a 1200 model.....it's a 5A glass fuse
If you have a 1210 model.....it's a 8A glass fuse
Both AC heaters should have a resistance measurement of 58-64 Ohms at ambient temp (must be at ambient for correct reading)
Amp draw should be 1.8A for each heater
IF fuse is good (and fuse clips) you can unplug heaters, wire them directly to 110V AC power source.......run fridge overnight and check temps.
If it cools correctly with heaters wired directly.......control board
