Refrigerator Repair

Built-in and integrated fresh-food columns that have stopped holding: defrost and airflow faults, condensers boxed into rehab joinery with nowhere to breathe, control boards, and the sealed-system work underneath all of it.

Hands fitting a charging hose to the brass service valve on the copper line beside a refrigerator compressor, a manifold gauge set resting on the floor

How it gets described on the phone

  • Fresh-food column creeping into the forties while the freezer beside it still sits at zero
  • Compressor running through the night in January, when the kitchen itself is cold
  • Puddle under the crisper drawers, or a sheet of ice spreading across the cabinet floor
  • Door that eases back open a second after you push it shut

What actually gets tested

  1. Shelf and evaporator temperatures taken with a probe, alongside the display rather than from it
  2. Condenser condition and the air path at the grille — the first thing tight rehab joinery ruins
  3. Evaporator fan, defrost heater and thermistors on the fresh-food circuit
  4. Sealed system under gauges: suction and discharge read while the cabinet is working
  5. Gasket compression, hinge alignment and the closer, because a door that never quite shuts loads everything behind it

A built-in running two cooling circuits can lose the fresh-food side while the freezer holds perfectly, and that single pattern rules out most of the expensive answers before a panel comes off. What is left is nearly always one circuit: airflow, defrost, a sensor reporting a temperature the cabinet is not at, or a condenser that stopped rejecting heat some months ago.

  • Fresh food side climbing into the forties while the other column sat perfectly at zero. He treated them as two separate machines, which is apparently how they work, and found one bad sensor.

    Ravi S. · River West · March 2026

  • Door had stopped self-closing and was resting open a finger width all day, which explained the running. Hinge cartridge and a new seal, both carried on the van, both done inside the hour.

    Colette D. · Wicker Park · April 2026

  • Loft conversion with the cabinet sunk into a brick alcove that traps every bit of heat. He measured the ambient around it, cleaned a condenser that had never been touched, and changed the fan.
