The answer to 'my zone control system keeps shutting off' is that there are several common causes, including a faulty thermostat, problems with the zone dampers, or issues with the control board. Symptoms may include the system cycling on and off frequently, uneven temperatures in different zones, or the system not responding to temperature changes.
Some possible solutions include checking the thermostat batteries, cleaning or replacing the zone dampers, or troubleshooting the control board. However, diagnosing and repairing a malfunctioning zone control system often requires the expertise of a professional HVAC technician, especially if the issue is with the electrical components or requires system reconfiguration. It's generally best to call in a pro to ensure the problem is properly identified and resolved to prevent further issues or damage to the system.
