When our Autohelm 4000 Autopilot is in control of the boat and our Adler Barbour Super cold machine is starting it's cooling cycle, the Autohelm display start flashing, showing: 4001 and the autopilot disengage itself. The boat always turn to the right by 20 to 30 deg. The pilot is now in Stand by mode. One push on the Auto button will set the Autopilot back on track for anywhere from 15 to 25 minutes, until the Adler Barbour start a new cooling cycle. It took us several weeks to find out what was the problem with the Autopilot, but finally made the association with the fridge.My electrical expertise is minimal but I have checked the wiring for size and all connections, everything is OK. Electronic and Fridge are on separate and distant cuircuit breakers in the panel. House battery are new (4 group 31 with more than 450 amps) and this situation occurs even if batteries are fully charged and when the motor is running. The fluxgate compass is 8 feet away from the compresor.Any help would be greatly apreciated.
