About the HFZ124
The HFZ124 is a 24-inch electric freezer from the 1 Class Collection, and it shares its cabinet with the UHFZ124. Placed beneath a counter or in a utility area, it keeps frozen food at a steady temperature as long as the door seals and the evaporator stays clear.
An HFZ124 visit begins with the gasket, which we inspect for tears and frost lines. Next we test the defrost parts and compare the temperature inside with the control. Heavy frosting tells us that warm air is getting in or defrost has stalled, and we follow whichever applies. A control that drifts from its setting comes last. A written price comes before we start.
What we check on a HFZ124 visit
- Gasket tears and frost lines
- Defrost parts operation
- Interior temperature against the control
Key features
- Freezer in the 1 Class Collection, 24 inches wide
- Electric cabinet
- Same build as the UHFZ124
The model number is on the serial label: inside the cabinet near the top, on the side wall or behind the front grille. We are an independent repair company, not affiliated with U-Line Corporation.

Why is the evaporator in my HFZ124 covered in frost?
Either warm air is entering or defrost is not working. We check the gasket first, then the defrost parts.
My HFZ124 does not match its setting. What do you check?
We measure with a thermometer and compare it with the control. A difference points us to the sensor or control.
