I finally figured out why the fridge would randomly short cycle.
It was the second fan I installed to vent the cabinet. Specifically, the fan was getting jammed by the power wires for the fridge. In order to allow removal the harness is about 24" long, and gets pushed behind the fridge during installation. Over time it was migrating back, and stopping the fan blades. This would result in a fan driver overcurrent error. The fridge would shut down, and restart about a minute later, only to repeat the process every 10 minutes or so.
The mods to the fridge are working well. The freezer now stays where I set it (about 17F currently), and the fridge compartment has been hanging in the mid 30s. The down side is that power consumption is back to pre SEC controller levels. Thats expected, with the freezer actually being a freezer now (ice cream anyone?).
The half-assed repair of the Espar hydronic has failed. I am getting a error 32, which is "fan short circuit". Either than fan motors windings have melted, or my wiring splice has. The fan does not move when I blow air through the exhaust (the other one did), so I am assuming the motor is gone. Of course parts are tough to find for the newest model... Hopefully I can find something reasonably priced. The other option is to refurb the motor I took off.. For now I have just been using the engine to heat the water when we drive. I need to reset the overtemp switch so I can use the 120V option.
