Use a multimeter to check for voltage at the power source. If there’s no power, your furnace won’t operate.
Thermostat Settings
Next, review the thermostat settings. Incorrect settings can prevent the furnace from working:
- Ensure the thermostat is set to “Heat”.
- Adjust the temperature setting above the current room temperature.
- Check the battery level in the thermostat, if applicable.
Replace old batteries to ensure proper communication between the thermostat and furnace.
Inspecting Components
Inspecting components is a crucial step in Atwood Furnace troubleshooting. Identifying issues early can save time and money. This section will help you inspect the burner assembly and heat exchanger.
Burner Assembly
The burner assembly is essential for proper furnace operation. Make sure the burner is clean and free of debris.
- Remove the burner cover.
- Check for visible dirt and grime.
- Use a soft brush to clean the burner.
Next, inspect the burner nozzle. The nozzle should be free of clogs. If clogged, use a needle to clear it.
Check the burner flame. A healthy flame is blue and steady. If the flame is yellow or flickering, it may indicate a problem.
Heat Exchanger
The heat exchanger is another vital component. It transfers heat from the burner to the air. Inspecting the heat exchanger involves several steps.
- Turn off the furnace and let it cool.
- Remove the access panel.
- Look for cracks or holes.
Use a flashlight to examine the inside thoroughly. Any cracks in the heat exchanger can cause carbon monoxide leaks. Replace the exchanger if you find any damage.
Ensure the heat exchanger is clean. Dust or soot can reduce efficiency. Use a vacuum to remove any buildup.
By carefully inspecting these components, you can ensure your Atwood Furnace runs efficiently and safely.
Cleaning Procedures
Keeping your Atwood furnace clean is essential for its efficiency. Regular cleaning helps prevent potential issues and prolongs the furnace’s life. This section covers essential cleaning procedures to keep your furnace in top condition.
Filter Replacement
The filter in your Atwood furnace traps dust and debris. Over time, it gets clogged, reducing airflow and efficiency. Replace the filter every 3-6 months for optimal performance.
Steps to replace the filter:
- Turn off the furnace.
- Locate the filter compartment.
- Remove the old filter.
- Insert a new filter.
- Close the compartment.
- Turn the furnace back on.
Vent Cleaning
Clean vents are crucial for proper air circulation. Dirty vents can cause blockages and reduce heating efficiency. Clean the vents at least once a year.
Steps to clean the vents:
- Turn off the furnace.
- Remove the vent covers.
- Use a vacuum to clean inside the vents.
- Wipe the vent covers with a damp cloth.
- Reattach the vent covers.
- Turn the furnace back on.
A clean furnace ensures better performance and longer life. Regular filter replacement and vent cleaning are simple but crucial steps.
Testing Electrical Connections
Testing the electrical connections in your Atwood furnace is crucial for smooth operation. This process helps identify issues such as faulty wiring or blown fuses. Proper testing ensures your furnace runs efficiently and safely.
Wiring Inspection
Inspect the wiring connections of your Atwood furnace. Start by turning off the power supply. Check for loose or damaged wires. Use a multimeter to test for continuity. Replace any damaged wires immediately. Ensure all connections are secure. Use wire nuts or connectors where needed.
Fuse And Circuit Breaker Check
Next, check the fuses and circuit breakers. Locate the fuse box and circuit breaker panel. Identify the fuse or breaker for the furnace. Remove the fuse and inspect for damage. Replace blown fuses with ones of the same rating. Reset any tripped circuit breakers. Ensure the power supply is consistent.
Here’s a quick checklist for electrical testing:
- Turn off the power supply
- Inspect all wiring connections
- Test for continuity using a multimeter
- Replace damaged wires
- Check and replace blown fuses
- Reset tripped circuit breakers
Use this table to keep track of your inspection:
| Task | Status | Notes |
|---|---|---|
| Power supply off | ✔️ | Ensure safety |
| Wiring inspection | ✔️ | Check for damage |
| Fuse check | ✔️ | Replace if blown |
| Circuit breaker check | ✔️ | Reset if tripped |
Proper testing of electrical connections ensures your furnace runs smoothly. Regular inspections help maintain its efficiency and safety.

Gas Supply Issues
When dealing with an Atwood furnace, gas supply issues can be common. Ensuring a steady gas supply is essential for proper furnace operation. Below are some key areas to inspect and troubleshoot.
Gas Line Inspection
The first step is to check the gas line. Examine the gas line for any visible damage or leaks. Use a soap and water solution to detect leaks. Apply the solution to the gas line and watch for bubbles. Bubbles indicate a leak in the gas line. If you find a leak, turn off the gas supply immediately and call a professional.
| Step | Action |
|---|---|
| 1 | Inspect the gas line for visible damage |
| 2 | Use soap and water solution to check for leaks |
| 3 | If bubbles appear, turn off the gas supply |
| 4 | Contact a professional for repair |
Gas Valve Operation
The gas valve controls the flow of gas to the furnace. Ensure the gas valve is in the “on” position. If the valve is off, the furnace will not receive gas. Test the gas valve operation by turning it on and off. Listen for a clicking sound. This indicates the valve is working correctly.
- Locate the gas valve near the furnace
- Ensure the valve is in the “on” position
- Test the valve by switching it on and off
- Listen for a clicking sound
If the valve does not click, it may be faulty. A faulty gas valve needs professional attention. Do not attempt to fix it yourself.
