Said on the phone

What people describe when they call about this

  • Ice along the drawer runners until the drawer will not close flush
  • Freezer holding in the teens while the display still reads zero
  • Compressor running all afternoon without ever cycling off
  • Sheet of frost rebuilding on the rear panel days after being cleared

What it usually turns out to be

Four findings, in the order they get checked

Frost is information. Where it forms, and how fast it comes back after you clear it, narrows a freezer fault down to two or three parts before anything is opened up.

  1. The defrost heater or its thermostat

    A sheet of frost rebuilding on the rear panel within days, and a compressor that never seems to cycle off. The box is making cold and then insulating itself from it.

  2. A plugged drain and a torn drawer seal

    Ice along the drawer runners until the drawer will not sit flush. Warm air gets in at the seal, condenses, freezes, and the meltwater cannot leave.

  3. A thermistor reading badly

    The display insists on zero and the ice cream is soft. The control is not lying to you on purpose; it is being told the wrong temperature by a sensor that has drifted.

  4. A seized evaporator fan

    Temperature drifts up while the compressor runs all afternoon. Often audible before it fails outright — a tick, a hum, or a fan that stops when the drawer is opened.

What it costs

What these repairs run, before anyone opens the cabinet

Flat $89 service call covering the visit and full diagnosis, credited against the repair once you approve it.

Door gasket or seal replacement
$280–$620
Evaporator or condenser fan motor
$320–$690
Defrost heater, thermostat or sensor
$270–$600
Ice maker, water valve or supply line
$280–$760
Electronic control board
$430–$940
Compressor or sealed-system repair
$1,430–$3,420

Where a repair falls inside its band comes out of the diagnosis, not the phone call. You are told the figure for your own unit and you agree to it before anything is opened up — and the $89 service call comes off that figure the moment you approve the work.

For scale: replacing the unit instead runs $12,740–$21,020 for a comparable built-in replacement, before installation and cabinetry work — which is why a sealed-system repair on a cabinet that is otherwise sound is usually still the cheaper road, and why it is worth measuring the box before anyone talks about taking it out of the run.

  • Freezer alarm went off near midnight and somebody actually picked up the phone. He told me to move things into coolers, came first thing in the morning, and found a seized evaporator fan.

  • The display insisted on zero but the ice cream was soft, which is how we caught it. A thermistor reading badly, swapped on the spot. The arrival window I was given was very wide though.

  • Ice built along the drawer runners of our freezer column until the drawer would not sit flush. A torn seal and a plugged drain trough, both dealt with in one visit. No frost since.
