TL;DR
A logic board is the main printed circuit board of an appliance or electronic device, hosting the processor or control chips that run every function from cycle timing to touch input. In appliance work it is often called the control board and is a frequent failure point after power surges; in phones and laptops it carries the CPU, memory, and charging circuitry.
What it means
A logic board is the main printed circuit board of an appliance or electronic device, hosting the processor or control chips that run every function from cycle timing to touch input. In appliance work it is often called the control board and is a frequent failure point after power surges; in phones and laptops it carries the CPU, memory, and charging circuitry. Because a replacement can approach half the price of a new unit, diagnosing whether the fault is truly on the board — and not a sensor or cable — is the critical step.
