AC Circuit Board Replacement in Spokane, WA
The circuit board — sometimes called the control board or ICM — is what coordinates signals between your thermostat, compressor, blower, and safety switches. When it fails, the system may not start at all, may short-cycle, or may run one component but not another. Board failures can look like a lot of other problems, which is why we verify it's actually the board before ordering the part. A misdiagnosed board replacement solves nothing.

When to Call
When You Need AC Circuit Board Replacement
- Your AC turns on briefly then shuts off before cooling the house at all

- A lightning storm came through Spokane and your system stopped working the next day
- The blower runs but the compressor never kicks on and wiring checks out clean
How It Works
Our Process for AC Circuit Board Replacement
- 1
Control Circuit Diagnosis
We trace the full control circuit with a meter — thermostat signals, 24V transformer output, and board outputs to each load.
- 2
Board Confirmation
We confirm the board is receiving correct input signals but failing to produce correct outputs before calling it the failed component.
- 3
Replacement and Programming
The new board is installed, any required DIP switch settings or jumpers are configured to match your system, and connections are verified.
- 4
Full System Cycle Test
We run the system through a complete cooling cycle to confirm all components respond correctly to the new board.
Spokane Context
Why this matters in Spokane
Spokane's summer thunderstorms produce power surges that are one of the leading causes of control board failure we see. If your system quit after a storm, the board is one of the first things we check.
Straight Talk
About pricing & scope
Board cost varies significantly by brand and system age — some boards are common and available locally, others require special ordering. If your system is old enough that the board is discontinued, we'll tell you that before you spend money on a repair that can't be completed.
