Norcold 682: Propane Issues

Thank you for your comments, Chris... I spent several hours yesterday using the troubleshooting guide that Old Biscuit graciously provided. I have the impression that the control board is fine. I'm not getting a clear indication whether the ignition control module or the eyebrow board are bad. I have to repeat some tests... And, I have to figure out a way to get to the electrode. The screw holding it in is rusted and its head is shot. A tough bugger to remove to check the electrode.... Speaking of the humidity switch, one test suggested an open circuit at the humidity/storage harness, which I guess is that switch. I managed to pull that tiny think out and found six little jacks (5 in use) on the back. One wire was disconnected and I reconnected it thinking that might have been the open circuit... The colored wires "resembled" the wiring diagram I have for that switch, except one extra wire was yellow and seemed to trail toward the on-off light switch nearby. I couldn't remove the light switch to see, so I'm not sure... One thing that threw me was the switch's wiring diagram that said "Front View." Does that mean looking at the front of the refrigerator? Or, is the front the side of the switch where all the wires plug in? The wires seem to match the notion that the side of the switch where the wires plug in is actually the front... (I need more coffee for this...) Regards- Gary
