Freezer Repair
Defrost, drain and temperature-drift repairs on Sub-Zero freezer columns, drawers and built-in sections.
Ice where ice should not be is a drainage or a sealing problem far more often than a refrigeration problem. A freezer that is still making cold but growing a sheet of frost on the back wall is telling you its defrost cycle or its drain has stopped working, not that the cabinet is finished.

Other Sub-Zero work
What people describe on the phone
- Ice sheeting across the rear panel a week after it was cleared
- Freezer drawer frozen shut or dragging on its rails
- Cabinet holding above ten degrees through a hot spell
- Water tracking out of the freezer onto the kitchen floor
On the day The rear panel comes off. Frost pattern, heater resistance, sensor readings and the drain are all checked in one visit, and the drain is flushed before the panel goes back on whether or not that was the fault.
What it usually turns out to be
- Defrost heater open circuit — frost builds on the rear panel until airflow stops
- Defrost thermostat or sensor reading wrong, so the cycle never runs or never ends
- Drain line iced solid, which puts meltwater on the cabinet floor and then on yours
- Door gasket torn at a corner or shrunk by dry air, pulling humid room air in continuously
- Drawer rails packed with ice so the front will not seat, which makes the icing worse
- Evaporator fan blade fouled by frost and running out of balance
What it costs
Six bands, then one figure you agree to
Flat $89 service call covering the visit and full diagnosis, credited against the repair once you approve it.
- Door gasket or seal replacement $280–$600
- Evaporator or condenser fan motor $350–$670
- Defrost heater, thermostat or sensor $300–$600
- Ice maker, water valve or supply line $300–$820
- Electronic control board $450–$930
- Compressor or sealed-system repair $1,410–$3,070
Each one is a range because the part, the access and how long the fault has been running all move the total inside it. Once the diagnosis is done you get a single figure for your repair — part and labour together — and it is agreed with you before any work starts. The $89 you have already spent on the visit comes off that figure the moment you approve it.

Our pop-top remodel put the freezer drawer beside a sunny window and it kept frosting at the back. He found the seal torn at a corner and the drain plugged with ice. Clean panel weeks later.

Freezer went warm on a Saturday with a whole elk order inside, and someone picked up the phone right away. The defrost thermostat had failed open. He shifted the meat into coolers while the cabinet came back down, then stayed to check it.

The freezer half of our paired columns frosted over at the back within a week of moving in. A defrost sensor was reading high. Replaced, drain flushed, pull-down watched.

How a call runs
Three steps, and you approve the middle one
Nothing is ordered, fitted or charged for beyond the service call until you have heard the fault and the figure.
-
01
Tell us what the cabinet is doing
Temperatures on both sections, any noise, and the model number from the frame inside the fresh-food door. That is enough to bring the likely part on the van instead of finding it on a second trip.
-
02
Panel off, readings taken
The toe grille and rear panels come off, the condenser and fans are inspected, defrost and sensor circuits are read with a meter, and gauges go on the sealed system when the symptom points there. You get the fault and one figure for fixing it.
-
03
Fitted, then proved
The part goes in, the drain is flushed, and the unit is watched through a full pull-down and a defrost cycle before anyone leaves. You see the temperatures come back on the meter, not on a promise.
