What this video covers

Replacing a mechanical refrigerator thermostat with a digital Carrel controller allows for precise temperature monitoring and improved compressor efficiency.Watch The installation requires wiring the digital unit to the compressor’s T and C spade terminals, which triggers the compressor cycle based on a set-point temperature.2:42 On a Vitrifrigo dorm-style refrigerator powered by a Danfoss BD35 compressor, the process involves mounting a temperature probe mid-level inside the fridge compartment and running the sensor wire through a drilled hole, which must be sealed to prevent moisture ingress.5:31 The thermostat requires a 12V power supply, which can be tapped from the compressor’s existing power leads, protected by an inline fuse.2:18 Wiring connections for the Carrel unit typically involve terminals 2 and 3 for the compressor trigger, 6 and 7 for power, and 8 and 10 for the temperature probe.15:12 Using tinned marine-grade wire is recommended to prevent corrosion in the boat's humid environment.17:31 Understanding the refrigeration wiring and compressor control logic provides a reliable troubleshooting path for future cooling failures.4:39
