If your heat is not turning off, it could be due to a malfunctioning thermostat, stuck valve, or a problem with the heating system's wiring. First, check the thermostat to ensure it's set correctly and functioning. If the thermostat seems fine, the issue might lie with the heating system itself. Inspect the valves to see if any are stuck in the open position. Should these steps not resolve the issue, it's advisable to contact a professional HVAC technician to diagnose and fix the problem safely and efficiently.
