Here is a picture of what Poobah is talking about on the old style board. Notice the slightly different locatin of the fan output terminals as well. On the new board J2 pins are in line with the J5

OK, J1 is the same connector I measured the resistance on earlier.  Counting from the left Terminals 1 and 2 on the connector have individual white/yellow wires that join about two inches out of the connector and dissapear as a single white/yellow wire into the fridge. 

In other words I don't believe I see the 'jumpering' I'm looking for, or should I be snipping one of those wires?

From what Poobah is describing this is the jumper wire. I only show a single FF thermistor for your model so they must have used the same one for input to terminal 1 & 2. Since your resistance was the exact same I suspect you are on track. Cut the wire leading to J1 - 1 leaving yourself some room if you need to splice it back.

From what I found the original board number was WR55x10174 which no crosses to the WR55X10552.

BTW sorry I wasn't more specific on how & where to test the thermistors.

Here you have it. Remove the molex plug from the board to test. Pin 5 is common to all the sensors so put one lead there and leave it. Then check from 1-5, 2-5, 3-5,4-5 - If there is not a wire on 1 or 2 don't worry, record the readings and take a look at this to see where your numbers fall.
