Range hood controls unresponsive or acting erratically

Electronic hood controls can lock up; a full power reset clears many cases. If not, check the ribbon or harness between the control panel and the main board, then replace the control panel or board. On hoods with Bluetooth or cooktop pairing, an active pairing can make the hood switch on by itself.

Range hood ducting: duct size, route, termination and makeup air

Hood performance depends more on the duct than the blower. Use the duct size the hood requires (never smaller), smooth metal duct, as few elbows as possible, and a proper wall or roof cap with a damper. Larger hoods can trigger a makeup-air requirement under local code (commonly when the hood can exhaust more than 400 CFM in homes with certain fuel-burning appliances).

Range hood turns on by itself or jumps to high speed

Many hoods (e.g. Broan Heat Sentry and similar) have a heat sensor that starts the fan or raises speed when it senses excess heat. That is a safety feature, not a fault. If it runs with a cold cooktop, suspect the sensor, a stuck switch or the control.
