# Sub-Zero evaporator replacement cost

### Standalone, or part of sealed system work

Quoted together with sealed system repairs, evaporator jobs commonly land at $2,000–$3,000. On its own the figure sits well below that. Which one you are looking at depends on what the diagnosis finds, and that is not something anyone can settle over the phone.

### What usually leads here

- Heavy frost on one shelf while the rest of the cabinet reads normal
- A zone that will not hold its set point
- A defrost cycle that never quite finishes

### What is checked with it

The defrost heater and thermistor are tested during the same visit, because replacing an evaporator and leaving a failed defrost component behind means doing the work twice.

What moves this figure

Cheaper on its own than combined with sealed system work

The defrost heater and thermistor are checked with it

Access is planned before the visit, not discovered on the day

What is checked with it

Which zone it is

A dual-refrigeration cabinet has two evaporators. Replacing the one that failed is the job; the other side keeps running and is not part of the figure.

What let the frost build

A defrost heater or thermistor that failed is usually why the coil iced in the first place. Replacing them alongside is what stops the same call coming back in a season.

How the coil is reached

The evaporator sits behind panels inside a cabinet fitted to your kitchen. How much has to come out to reach it varies more between installs than the part does between models.
