Common Causes of Humidifier on Furnace Not Working
Several factors might cause your humidifier to stop functioning on your furnace. Identifying the root issue can lead to effective solutions.
Incorrect Settings
Incorrect settings might prevent your humidifier from operating. Check the humidity control settings on your thermostat or humidistat. Make sure it’s set to the desired humidity level. If it’s set too low, the humidifier won’t activate. Adjust these settings as needed to ensure optimal performance.
Clogged Filters
Clogged filters restrict airflow, causing your humidifier to malfunction. Regular maintenance is essential for proper operation. Inspect the filters every month and clean or replace them as necessary. A clean filter promotes efficient airflow, ensuring your humidifier works effectively.
