Common issues

Common Reasons Your Sub-Zero Freezers Is Not Working

A Sub-Zero freezer that is not working usually points to one of several diagnosable faults. Our technicians arrive with Sub-Zero parts on the truck so most Sub-Zero Freezers Repair jobs in Norcross are fixed in a single visit.

  • Issue 01

    unusual noise

    How we fix it

    When a Sub-Zero freezer shows unusual noise, the cause is often Refrigerant gurgling through lines — normal in some models but louder when partially low, Drain pan loose and vibrating against frame, and Worn compressor motor bearings producing whining. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 02

    water pooling on floor

    How we fix it

    When a Sub-Zero freezer shows water pooling on floor, the cause is often Door gasket leak causing condensation to run down exterior and pool, Freezer positioned on uneven surface causing water to run to one side and off drain pan, and Refrigerant leak causing surrounding moisture to condense and drip. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 03

    freezer not starting

    How we fix it

    When a Sub-Zero freezer shows freezer not starting, the cause is often Main control board power supply failure, Damaged power cord, plug, or receptacle, and Internal fuse blown on main board due to power surge. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 04

    freezer over-freezing or too cold

    How we fix it

    When a Sub-Zero freezer shows freezer over-freezing or too cold, the cause is often Thermostat calibration drift — set point reading and actual control point separated, Defrost system over-running cooling period — uneven cycle compensation, and Temperature control thermostat stuck in closed position — calling for cooling continuously. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 05

    not freezing

    How we fix it

    When a Sub-Zero freezer shows not freezing, the cause is often Compressor failure — not circulating refrigerant through system, Low refrigerant charge due to leak in sealed system, and Dirty condenser coils blocking heat release. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 06

    excessive frost buildup

    How we fix it

    When a Sub-Zero freezer shows excessive frost buildup, the cause is often Defrost thermostat failed — not signaling heater to turn on, Defrost timer not advancing or stuck in refrigeration mode, and Door gasket torn or improperly seated allowing warm humid air to enter. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 07

    temperature too warm

    How we fix it

    When a Sub-Zero freezer shows temperature too warm, the cause is often Low refrigerant causing inefficient heat exchange, Condenser coils extremely dirty reducing heat rejection, and Freezer overpacked, blocking internal air circulation vents. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.

  • Issue 08

    door not sealing

    How we fix it

    When a Sub-Zero freezer shows door not sealing, the cause is often Freezer not level, causing lid or door to rest at an angle, Heavy overloading causing door frame to distort slightly, and Frost or ice buildup on door gasket preventing full contact. Our experienced Norcross technicians diagnose and repair using genuine parts from authorized distributors.
