Freezer repair for Sub-Zero columns and freezer drawers
A Sub-Zero freezer that drifts above zero seldom hides a mystery. Air stops moving, the coil ices over, a sensor reads wrong, or the sealed system loses its charge. SubZero Repair Denver works through those in that order, cheapest suspect first.
Which freezer you have changes the visit
- Freezer columns
- Tall integrated freezers behind a cabinet panel. The panel and the grille have to come off before any part can be reached, so tell us whether yours is a column when you call.
- Freezer drawers under a refrigerator
- The bottom drawers of an over-and-under built-in. Most full-size Sub-Zero models cool the freezer separately from the fresh-food section, so a warm drawer under a cold refrigerator points at the freezer's own fan, coil or defrost parts.
- Undercounter freezers and freezer drawers
- Compact units with the machinery packed into the base, breathing through the grille at the floor. They have their own page, because their weak points differ.
What the $89 visit checks, in order
- Temperature, with our own probe in a drawer or on a shelf, not just the display.
- The evaporator fan: does it spin, and does it stop when the door opens.
- The coil behind the back panel: clear, frosted in patches, or a solid block.
- The defrost heater, its thermostat and the sensors the control relies on.
- The condenser and its fan: dust, airflow, how hot the coil runs.
- The door or drawer gasket, tested with paper all the way round.
- Only after all that, the compressor and the sealed system.
Typical ranges for freezer repairs
| Job | Typical range |
|---|---|
| Visit and diagnosis | $89, credited |
| Fan motor, in the freezer or at the condenser | $310–$730 |
| Defrost heater, termination thermostat or sensor | $290–$670 |
| Door or drawer gasket | $280–$700 |
| Control board | $450–$910 |
| Compressor or sealed system | $1,450–$3,060 |
A range is a guide, not a quote. The actual figure comes after diagnosis, you decide before anything is replaced, and the visit fee is subtracted from it.
Household freezers only
Reach-in and walk-in freezers in restaurants and shops are a different trade with different parts. We work on Sub-Zero units in homes, so for a commercial box a refrigeration contractor is the right call.
Two questions about freezers
Can I defrost the freezer myself to get it going again?
You can, and it often buys a few days: switch it off, empty it, prop the door and towel up the melt. But if the coil iced over because a defrost part failed, the ice grows back within days. Tell us you did it, because a freshly thawed coil hides the evidence we look for.
Why does the freezer seem to run all evening?
A freezer that cannot finish a cycle runs longest when the kitchen is warmest and the door opens most, which is during and after dinner. With Xcel's time-of-use rate those are the expensive hours, 5 to 9 p.m. on weekdays, so a freezer that never seems to rest is worth a call to (720) 770-4189.
