Lubricate Moving Parts
Moving parts in the furnace should be lubricated regularly. This reduces friction and noise.
- Turn off the furnace power.
- Locate moving parts such as the motor and fan.
- Apply a few drops of high-temperature lubricant to these parts.
- Wipe away any excess lubricant.
- Turn the power back on and check for noise reduction.
Lubrication helps keep the furnace parts moving smoothly. This can significantly reduce or eliminate unusual noises.
| Noise Type | Possible Cause |
|---|---|
| Banging | Dirty burners |
| Rattling | Loose panels or screws |
| Whistling | Clogged filter |
| Squealing | Belt or motor issue |

Pilot Light Problems
Experiencing issues with the pilot light on your Atwood furnace? This guide will help you troubleshoot common pilot light problems. A malfunctioning pilot light can prevent your furnace from heating. Let’s dive into the most common solutions.
Relight Pilot Light
If your pilot light goes out, you need to relight it. Follow these steps:
- Turn off the gas supply.
- Wait five minutes to clear any gas.
- Find the pilot light assembly.
- Turn the control knob to “Pilot”.
- Press and hold the reset button.
- Use a long lighter to ignite the pilot.
- Release the reset button once the pilot is lit.
Make sure the pilot stays lit. If it goes out, repeat the steps.
Check Gas Supply
Ensure you have a steady gas supply. A disrupted gas supply can cause pilot light issues.
Follow these steps to check your gas supply:
- Verify that the gas valve is open.
- Check the gas tank for fuel.
- Inspect the gas lines for leaks.
Use a mixture of soap and water to detect leaks. Apply it to the gas lines. Look for bubbles forming. If you find a leak, contact a professional.
Maintaining a steady gas supply ensures your pilot light stays lit. Make sure to inspect these components regularly.
Blower Motor Issues
Experiencing issues with your Atwood Furnace blower motor can be frustrating. A malfunctioning blower motor can disrupt the heat flow in your home. This section will guide you through troubleshooting common blower motor issues.
Test Capacitor
The capacitor helps start and run the blower motor. If it fails, your motor may not run properly. Here’s how to test the capacitor:
- First, turn off the power to the furnace.
- Second, locate the capacitor in the blower motor assembly.
- Third, use a multimeter set to capacitance mode.
- Touch the multimeter probes to the capacitor terminals.
- Compare the reading to the capacitor’s rating printed on its side.
If the reading is significantly lower, the capacitor needs replacement.
Inspect Motor Bearings
Worn-out bearings can cause noise and reduce motor efficiency. Follow these steps to inspect the motor bearings:
- Turn off the power to the furnace.
- Remove the blower assembly from the furnace.
- Check for any play or roughness in the bearings.
- Spin the blower wheel by hand; it should rotate smoothly.
If you detect roughness or noise, the bearings may need lubrication or replacement.
| Problem | Possible Cause | Solution |
|---|---|---|
| Blower motor not starting | Faulty capacitor | Replace capacitor |
| Blower motor noisy | Worn bearings | Lubricate or replace bearings |
