Common Issues in Atwood Propane Furnaces
Atwood propane furnaces may present several common issues. Knowing how to identify and troubleshoot these problems helps maintain comfort and safety in your space.
Ignition Problems
Ignition problems often stem from an electrical issue or a faulty ignition system. If your furnace doesn’t ignite, check the following:
- Thermocouple Status: Ensure the thermocouple is clean and positioned correctly.
- Power Supply: Verify that there’s power to the unit. Check the circuit breaker and fuses.
- Gas Valve Function: Confirm that the gas valve opens when the thermostat calls for heat.
You can also reset the furnace if it has one. Refer to your owner’s manual for specific instructions on resetting the ignition system.
Insufficient Heating
Insufficient heating can occur for several reasons. Look into these factors:
- Clogged Filters: Inspect and replace air filters if they are dirty. Clogged filters restrict airflow and reduce heating efficiency.
- Duct Leaks: Examine ductwork for leaks or blockages. Seal any leaks with duct tape or mastic to improve heat distribution.
- Thermostat Settings: Ensure the thermostat is functioning correctly. If it’s set too low or is malfunctioning, it may not signal the furnace properly.
Running the furnace with proper maintenance enhances heating performance significantly.
Strange Noises
Strange noises from the furnace can indicate potential issues. Pay attention to these common sounds:
- Rattling: Rattling noises may suggest loose components. Tighten screws and ensure all parts are secure.
- Banging or Clanging: This may result from expanding metal as the furnace heats up. Such sounds are often normal but should be monitored.
- Whistling: Whistling can stem from air leaks in the ductwork. Inspect ducts for cracks or loose connections and seal them.
Addressing strange noises early can prevent more severe problems and ensure your furnace operates smoothly.
Troubleshooting Steps
Use these steps to address common issues with your Atwood propane furnace. Following these guidelines helps ensure proper operation and comfort in your space.
Checking the Thermostat
- Inspect Settings: Confirm the thermostat is set to ‘heat’ and the desired temperature is higher than the current room temperature.
- Replace Batteries: If the thermostat uses batteries, replace them to avoid power issues.
- Calibrate Status: Test thermostat calibration. If it’s off, readjust it according to the manufacturer’s instructions.
- Clean Contacts: Dust and dirt can impede function. Clean the contacts gently with a soft cloth.
Inspecting the Igniter and Flame Sensor
- Examine Igniter: Inspect the igniter for any signs of wear or damage. A damaged igniter often needs replacement.
- Test Flame Sensor: Clean the flame sensor using a fine sandpaper or a scouring pad to remove any buildup. This ensures it accurately detects the flame.
- Check Connections: Ensure all electrical connections related to the igniter and sensor are secure. Loose wires can lead to operational failures.
- Observe Operation: Watch the igniter try to start. If it doesn’t glow or ignite the gas within a few seconds, further inspection is necessary.
- Inspect Gas Valve: Ensure the gas valve is fully open. If it’s closed, open it and check for proper operation.
- Check Propane Levels: Verify that the propane tank is not empty. Low levels can cause heating issues.
- Look for Leaks: Use a soap solution on joints and connections to identify leaks. Bubbles indicate a problem that needs immediate attention.
- Assess Pressure: A gas pressure gauge can help determine if the pressure meets specifications. Low pressure may require professional assistance.
Maintenance Tips for Atwood Propane Furnaces
Regular Inspections
Perform regular inspections to ensure safe and efficient furnace operation. Look for signs of wear, rust, or damage. Check that all components function properly without excessive noise or vibration.
Verify Propane Supply
Confirm that your propane supply is sufficient. Low levels can lead to inconsistent heating or other performance issues. Keep an extra propane tank on hand for convenience during the cold seasons.
Clean Air Filters
Clean or replace air filters every month, especially in peak heating months. Dirty filters restrict airflow, reducing heating efficiency and putting extra strain on components. Ensure filters fit well to avoid gaps.

Test your thermostat settings periodically. Ensure it’s set to your desired temperature. Replace batteries in battery-operated thermostats annually to avoid unexpected failures.
Inspect Ductwork
Inspect ductwork for leaks or blockages. Use duct tape to seal any visible gaps. Ensure proper airflow to maintain consistent heating throughout your space.
Examine the Igniter and Flame Sensor
Examine the igniter and flame sensor during each maintenance check. Clean the sensor gently to remove any debris buildup. Replace faulty components promptly for reliable ignition.
Evaluate Gas Connections
Evaluate all gas connections for leaks. Use soapy water on joints to check for bubbles, which indicate leaks. Call a professional for leaking gas connections to ensure safety.
Keep Area Around Furnace Clear
Keep the area around the furnace clear of obstructions or flammable materials. This enhances airflow and reduces fire hazards. Ensure the furnace remains accessible for service and emergency situations.
Schedule Professional Servicing
Schedule professional servicing annually. A technician can perform a thorough inspection and clean components effectively. This proactive approach prolongs the furnace’s lifespan and enhances performance.
By following these maintenance tips, you maintain the efficiency and safety of your Atwood propane furnace, ensuring comfort in your living space throughout the cold months.
