Heat not turning on in certain areas of home

    1. Check the thermostat and make sure the temperature is set higher than the room’s temperature and it’s calling for heat.
    2. Check thermostats in the zone and replace batteries or any defective thermostats.
    3. Inspect the zone valves for the unheated rooms and make sure they are open. Open manually if closed.
    4. Bleed radiators and baseboards in the cold areas to remove trapped air preventing circulation.
    5. Check the radiator valves and make sure they are open fully to allow hot water flow.
    6. Inspect the circulating pump and filters for blockages. Clean and clear any found debris.
    7. Look for closed supply/return valves for the zone. Make sure all valves are open.
    8. Test the zone control board and replace if faulty. This controls power to the zone’s pump and valves.
