If your heat won't shut off, it's typically due to issues with the thermostat, furnace, or heating system's wiring. First, check if the thermostat is set correctly and functioning properly. Switching it off should test if the furnace responds. If there's no change, the problem might be stuck relays in the furnace or boiler. Calling a professional is often necessary to inspect and repair faulty wiring or malfunctioning parts. Regular maintenance can help prevent such problems, ensuring your heating system operates efficiently and safely.
