Freezer Repair

Freezer columns, drawer freezers and undercounter units that lose temperature, ice up, or run without stopping. Defrost circuits, evaporator fans and door seals are the usual starting points.

In your words

What people describe when they call

  • Everything in the drawer covered in frost
  • Freezer running constantly and never reaching setpoint
  • Loud rattle from the fan behind the rear panel
  • Gasket peeling away from the drawer front

On the visit

What gets measured

  • Cabinet temperature against setpoint through a complete run and defrost
  • Frost pattern on the evaporator, which says where the air is and is not moving
  • Defrost termination behaviour and heater continuity
  • Drawer rail alignment and gasket compression along the whole seal

Money, plainly

What the number is made of.

One figure is fixed: the $95 service call, which covers the visit and the diagnosis and comes off the bill when you approve the repair. The rest depends on which circuit failed.

Nobody quotes a repair down the phone here. A written estimate follows the readings, as one number for parts and labour together, and you can decline any line on it.

  • Which circuit failed. A condenser fan motor and an evaporator that has lost its charge are not the same job, and they are not close. Most of the spread in a refrigeration bill sits here.
  • Whether the cabinet has to come out. A full-height column in a tight back hall may need the door and the panel off before anything can be reached. Access is labour, and it is quoted as labour.
  • Part availability. Control boards and compressors for older platforms are ordered rather than carried. A part on the van and a part on order produce different visits and different totals.
  • What else the readings show. A defrost fault found alongside a failed door heater gets quoted as two items, both visible on the estimate, so you can decline either one.

Typical range, parts and labour

  • Door gasket or seal replacement $270 – $760
  • Evaporator or condenser fan motor $280 – $590
  • Defrost heater, thermostat or sensor $290 – $680
  • Ice maker, water valve or supply line $290 – $690
  • Electronic control board $470 – $940
  • Compressor or sealed-system repair $1,000 – $2,080

For scale, a comparable replacement cabinet runs $7,990 – $21,170 for the appliance alone, before delivery, installation or panel work. That is the comparison worth making before a large sealed-system repair.

  • Freezer column ran without ever stopping and still sat ten degrees too warm. The defrost heater had gone open circuit so the coil was packed solid in ice. Two hours of work and the ice cream is hard again.

  • Steep driveway, so he parked down the hill and carried everything up. The undercounter unit had quit dead: a shorted defrost thermostat had taken the fuse with it. Both replaced and he tested it before packing up.

    Gordon H.Arlington Heights

  • Our kitchen sits at the back of a three-decker and the freezer had drifted warm with no alarm at all. The thermistor was reading low so the compressor barely ran. Swapped, and he waited while it pulled down.

A call costs nothing. A visit is a flat $95, and that comes off the bill the moment you approve the repair.
