Leak and Overcooling Repair in BOHN Walk-In Cooler — Monte Sereno

✅ Monte Sereno, CA — Walk-In Fridge Leak and Overcooling Repair (BOHN System)

The owner of a specialty grocery store in Monte Sereno reached out to us with an urgent problem: the walk-in refrigerator was leaking, and internal temperatures had dropped below 30°F. While cold is necessary for food preservation, excessive cooling can be equally harmful — it leads to frozen condensation, equipment strain, and, in this case, water pooling on the floor.

✅ Our technician performed a full diagnostic (free with repair) and determined the cause: the drain heater had failed. With no functioning heater, the drain pan froze solid, preventing proper drainage and resulting in overflow.

✅ Rather than taking the typical route of simply replacing the part, our technician applied a more technical solution. To avoid shutting down the entire system — and risking damage to temperature-sensitive products — he temporarily rerouted power from the evaporator to locally activate defrosting. This targeted method allowed the technician to thaw the frozen drain area without affecting the rest of the refrigeration cycle.

✅ Once the ice was cleared, the drain line was fully cleaned to ensure long-term performance. A new drain heater was installed and carefully tested for stable operation, with all electrical connections verified and secured.

✅ Total cost of repair: under $600. The system is now running reliably, with stable temperatures and no further leakage.
