Evaporator Fan Motor Error
H1
Summit freezer display shows H1 or "HI" and an audible alarm sounds; interior feels warm.
High Temperature Alarm Condition
L1
Summit freezer display shows L1 or "LO" and the unit may run less frequently; contents may be too cold or slightly warm depending on fault.
Low Temperature or Sensor Calibration Error
Symptom
Buttons on the digital control panel do not respond or respond intermittently.
Keypad / Touch Control Failure
Symptom
Condensation or moisture forming on the exterior cabinet or around the door gasket.
Exterior Condensation / Warm-Moist Air Infiltration
Symptom

Display Power or Backlight Failure
Symptom
Freezer door does not close or seal properly; door pops open slightly after closing.
Door Alignment / Hinge or Gasket Problem
Symptom
Freezer door is hard to open immediately after closing; a vacuum seems to hold it shut.
Door Vacuum / Pressure Equalization
Symptom
Freezer emits a strong chemical, plastic, or burning smell.
Odor from Electrical or Plastic Components
Symptom

Interior Odor / Contamination
Symptom
Freezer interior is too cold; items are rock-hard and ice crystals form on packaging even at higher settings.
Overcooling / Thermostat or Sensor Out of Calibration
Symptom
Freezer interior light does not turn on when door is opened, but cooling is normal.
Interior Light Circuit Failure
Symptom
Freezer interior temperature fluctuates widely; items partially thaw and refreeze.
Inconsistent Temperature Control
Symptom
Freezer is completely warm inside but compressor and fans are running continuously.
Sealed System Failure (Refrigerant Leak or Blockage)
Symptom
Freezer makes a high-pitched squealing or chirping noise from inside the cabinet.
Evaporator Fan Motor Bearing Wear
Symptom
Freezer makes gurgling, hissing, or popping sounds periodically.
Normal Refrigerant Flow and Defrost Noises
Symptom
Freezer makes loud buzzing or humming noise, especially when compressor starts.
Compressor Start Device or Mounting Noise
Symptom
Freezer makes loud rattling or vibrating noise, especially when compressor is running.
Cabinet Vibration or Loose Components
Symptom
Freezer not cooling at all; interior is room temperature and compressor is not running.
No Power or Failed Electronic Control
Symptom
Freezer runs but does not get cold enough; food is soft or partially thawed.
Poor Cooling / Loss of Capacity
Symptom
Freezer runs constantly and rarely shuts off, even when interior seems cold.
Long Run Time / Control or Air Leak Issue
Symptom
Freezer trips the household circuit breaker or GFCI outlet.
Electrical Overload or Ground Fault
Symptom
Freezer will not start after being transported or moved.
Post-Transport Start Delay / Oil Migration
Symptom
Heavy frost buildup on shelves, walls, and food packages.
Excessive Frost / Air Infiltration
Symptom
Interior fan does not run; cold air is not circulating, leading to uneven temperatures.
Evaporator Fan Not Operating
Symptom
Thick ice sheet forming on the evaporator cover or behind the rear interior panel.
Defrost System Failure
Symptom
Water or ice buildup on the bottom of the freezer compartment.
Internal Water Leak / Blocked Defrost Drain
Symptom
Water pooling on the floor in front of or under the freezer.
External Water Leak / Defrost Drain Overflow
