Sub-Zero Freezers Not Working Repair in Chamblee

When a Sub-Zero freezer shows water pooling on floor, the cause is often Drain plug on chest freezer removed, cracked, or not seated properly, Drain hose disconnected or kinked preventing water from reaching drain pan, and Door gasket leak causing condensation to run down exterior and pool. Our factory-trained Chamblee technicians diagnose and repair using genuine OEM Sub-Zero parts.

When a Sub-Zero freezer shows freezer over-freezing or too cold, the cause is often Temperature control thermostat stuck in closed position — calling for cooling continuously, Temperature setting accidentally turned to maximum coldest setting, and Electronic temperature sensor sending falsely high (warm) signal — board compensates by over-cooling. Our factory-trained Chamblee technicians diagnose and repair using genuine OEM Sub-Zero parts.

When a Sub-Zero freezer shows excessive frost buildup, the cause is often Auto-defrost control board malfunction, Defrost heater burned out or open circuit, and Defrost thermostat failed — not signaling heater to turn on. Our factory-trained Chamblee technicians diagnose and repair using genuine OEM Sub-Zero parts.

When a Sub-Zero freezer shows door not sealing, the cause is often Gasket pulled out of mounting channel, Door hinge or lid hinge bent, worn, or out of alignment, and Freezer not level, causing lid or door to rest at an angle. Our factory-trained Chamblee technicians diagnose and repair using genuine OEM Sub-Zero parts.
