A flue sensor checks flue temperature and helps the boiler run safely. It protects the boiler by detecting abnormal conditions in the flue system. When the sensor fails, the boiler may lock out, show fault codes, or cut out during use. You may also get incorrect readings that affect performance. Replace the correct flue sensor to restore safe control and reliable boiler operation.
