and required lubricant

Loop the blower motor's common wire through the relay bracket two or more times to increase the sensed current and ensure the humidifier relay triggers correctly

and the 3-amp fuse protects low-voltage components from overcurrent damage

Its low-pressure safety limit functionality protects the heat exchanger from improper fuel-to-air ratios

Repeated tripping is often the result of restricted airflow
