THUMBWHEEL - HARNESS FRZ (Crown CR125603-002)

A damaged thumbwheel can cause intermittent or failed input signals in control circuits. During operation, this rotary encoder component translates manual rotation into electrical signals for system adjustments. Crown originally cataloged this part under number CR125603-002. This aftermarket replacement thumbwheel provides the same mechanical function of converting rotational position into a variable resistance or digital output. A common failure mode is worn internal contacts, leading to erratic or unresponsive control behavior. The item ships at approximately 0.474 pounds.
