# GE control board replacement

What this involves

Ruled in by measurement, not by elimination-by-guess

Sensors and relays imitate a failed board

We say when the arithmetic favors replacement

Prove the inputs before condemning the brain

A board acting on a bad sensor reading is behaving correctly. Measuring the inputs is what separates the two.

Check power and connectors

Burnt connectors and loose grounds produce erratic behavior that reads exactly like a failed control.

Age it and price the alternative

GE's date code, the cost of the board, and what a replacement appliance would be. On some machines this is where we recommend against the repair.

Fit, configure and test every function

Boards often need model configuration, and a board fitted without it produces new symptoms of its own.

Configured, then every function tested

Many GE boards are configured to the model after fitting, and a board installed without it produces new symptoms of its own. We test the whole appliance rather than the complaint.
