Completed furnace, maintenance and inspection. I checked amp draws and tested components. I tested airflow and temp splits. I cleaned flame sensor and wiped down furnace. Furnace is operating within manufacture specifications. The humidifier had overflowed water down onto the furnace, so I turned down the amount of water coming through to avoid the humidifier from ruining components in the furnace. I checked out the components that the water had dripped by and the components were fine.
