# Sub-Zero control board replacement cost

### Why this one has the widest spread

Boards vary more by series than any other part on this list, and availability varies with them. A current-series board is a same-week job; a legacy 500, 600 or 700 Series board can take days to source. That range is real, and quoting a single number across it would be a guess dressed as a price.

### We confirm the board before ordering it

A code on the display is not proof that the board has failed — sensors, harnesses and the components the board reports on fail more often than the board does. Testing those first is what keeps this from becoming an expensive part that changes nothing.

### What else may be in the job

- A display or touch panel, sometimes the cheaper half of the repair
- Surge-related damage after storm season, occasionally with a second component
- Reprogramming or configuration where the series requires it

What moves this figure

The board is confirmed before it is ordered

Legacy 500, 600 and 700 Series parts are scarcer

A display or touch panel is sometimes the cheaper half of the job

Which generation the unit is

Boards differ more by series than any other part on this list. A current-series board is a same-week job; a legacy one is ordered and waited for, and priced accordingly.

Whether the board is really the problem

Sensors, harnesses and supply problems get blamed on boards routinely. Measuring first is what stops you paying for a part that changes nothing.

Display and touch panel

On some cabinets the display is a separate assembly from the control board. Where both have failed it is two parts, and where only one has, it is worth knowing which.
