Sub-Zero BI-36U Over-and-Under Repair
At 36 inches wide, the BI-36U gives a family-sized fresh food section above a freezer drawer, and it is most often built in beside a run of cabinets with a flush or overlay trim. A level cabinet and a clear gap around the toe grille help every one of these checks, so we confirm both when we arrive.
As the years pile up, fans start to complain and controls begin to disagree with what the cabinet is actually doing. Our first visit separates the two: we compare the displayed temperature with a probe reading inside, listen to the fans while running, and watch how fast the cabinet recovers after a door opening. A dusty grille or a tired gasket often explains slow recovery before anything electrical does.
We quote in writing first and give a 30-day workmanship warranty on the repair.
We place a calibrated probe inside the cabinet and compare it with the panel, then check the sensor and control. If the airflow is poor, the reading can be correct but the cabinet still warm.
Slow recovery usually means restricted condenser airflow, a leaking seal, or a fan that is not moving enough air. We check all three, starting with the cheapest to fix.
Often yes. We locate the noisy fan, clear any ice or debris, and replace the motor only when it is actually worn. You will know the cost before we proceed.
