Common Issues with Intertherm Gas Furnaces
Intertherm gas furnaces can encounter various issues. Knowing these common problems helps you troubleshoot effectively.
Ignition Problems
Ignition problems commonly occur, making it difficult for your furnace to start. Issues may arise from:
- Faulty Ignitor: A malfunctioning ignitor can prevent the burner from lighting. Identify a failing ignitor by looking for cracks or damage.
- Dirty Flame Sensor: A dirty flame sensor may not detect the flame, triggering the safety shutdown. Clean the sensor with a fine-grade sandpaper.

Insufficient Heat Output
Insufficient heat can leave you feeling cold and uncomfortable. Possible causes include:
- Clogged Air Filter: A clogged air filter restricts airflow, reducing heat. Replace your filter every 1-3 months.
- Closed Vents: Ensure all supply and return vents are open and unobstructed. Blocked vents can lead to uneven heating.
- Gas Supply Issues: Check for adequate gas supply. If your gas line appears shut off, open the valve or contact your provider.
- Rattling: Rattling sounds often result from loose panels or screws. Inspect the furnace and tighten any loose components.
- Banging: Banging noises might occur due to ductwork expanding or contracting. Insulate the ducts to minimize temperature fluctuations.
- Humming: A constant humming sound can suggest electrical issues. If you suspect wiring problems, get in touch with a qualified technician for assistance.
