Fixed it

Our refrigerator has been on the fritz. It would quit cooling the 'frige section while the freezer section stayed frozen. We took some advice we found on the internets and ended up defrosting the entire thing, not once, but twice. Every time we would plug it in, it seemed like within 12 hours it would throw this error code up on the display (though you would never know it was an error code unless you were a EE or CS with some experience) and eventually the upper section would quit cooling well and then finally quit cooling at all.

Being a former EE, I decided to pull out my trusty digital multimeter from Radio Shack (I love the little cheapo clam shell one) and started ohm'ing out the connections. I soon realized the defrost mechanism was showing as an open circuit. I ohm'ed out the defrost element on the coil and it was fine. So it had to be somewhere in between the control board and the defrost element. I finally found the circuit, ordered the parts to replace those that failed, and $20 and a day later it is still running. Yay.
