Diagnostic overview
Live voltage and signal tracing at the board, sensor input verification, output drive testing, and visual inspection for board damage.
Repair process
Confirm true board failure (not a downstream part) → replace or repair PCB → reconfigure → verify all outputs drive correctly.
When professional repair is appropriate
Control boards are expensive. We always confirm the board itself has failed — and not a sensor or compressor it's protecting — before recommending replacement.
