Addler Barbour Refrigerator Repair ~ Complete November 2015

The existing Adler Barbour Cold Power PB110LV-134 refrigerator had no breaker space alocated in the 12VDC space of the Nav Station instrument panel. Instead there was a breaker allocated in the 120VAC section which indicated that as-built the boat had an Alternating Current unit. As the refrigerator compressor is mounted below the LH end of the curved salon bench alongside its 12VDC auxilliary batteries it seemed useful to mount a small breaker panel in the same region. We selected a 3 breaker unit and allocated the breakers to the following 3 circuits, top to bottom.

Once the refrigerator was powered the compressor started and the cooling coil quickly chilled. The thermostat responded and within the 1 -> 7 range a setting of 4 produced a thin veneer of ice on the coils but did not continue to create an agressively thick coat. It was non-functional so it was replaced with another 100mm square brushless DC computer fan. The fan wiring was then connected back to the Fan power pins of the Adler Barbour controller and everything came to life. Examining the interior we found that a circulation fan had been placed in the wall between the 2 chambers of the refrigerator. The fan fits totally within the separation wall, so is not at risk of easy damage. Being at the bottom it pushes the coolest air falling from the freefer plate into the RHS cold storage chest, its return air flow between compartments through clearance at the top of the center separation wall . The use of a circulation fan between the 2 chambers is a very good design feature of the cabinetry and control system of the boats food refrigeration.

Refrigerator Efficiency Study ~ In-Process

One final thing to do was to replace the seal strip on the front opening door of the RH chest with " x " foam rubber sealing strip. With everything done we can keep Romaine lettuce fresh for up to 10 days in the RH chest. The refrigerator itself had been insulated on its back and side surfaces with Urethane Foam which helped maintain an ON ~ OFF duty cycle of about 30%. Looking at the 24-hour power consumption it calculated to 6.0 Amps x 24 hrs x 30% which is 43 Amp Hrs and well within the 50 Amp Hrs that is used as a figure of merit by many cruising sailors in the Caribbean. In total we are pleased that an Adler Barbour system purchased in 1997 is still in good working order nearly 20 years later.
