Is your Atwood water heater refusing to ignite when you need it most? That sudden chill can be frustrating, especially when you rely on hot water every day.
You might wonder why this keeps happening and what you can do to fix it quickly. Understanding the common reasons behind this problem can save you time, money, and stress. Keep reading, and you’ll discover simple, clear steps to get your water heater working again—so you never have to face cold water unexpectedly.
Common Causes Of Ignition Failure
When an Atwood water heater does not ignite, it often points to a few common issues. These problems stop the heater from starting and providing hot water. Understanding these causes helps to find the right fix fast.
Power Supply Issues
The water heater needs steady electricity to ignite. A loose wire or dead battery can cut power. Check the power source and connections. A weak power supply prevents ignition.
Thermocouple Problems
The thermocouple senses the pilot flame and allows gas flow. A damaged or dirty thermocouple stops gas from reaching the burner. Cleaning or replacing this part can restore ignition.
Gas Supply Interruptions
Gas must flow to ignite the burner. Blocked pipes or closed valves stop gas flow. Inspect the gas line for leaks or blockages. No gas means no ignition.
Pilot Light Malfunctions
The pilot light must stay lit to ignite the main burner. Dirt, drafts, or faulty parts can extinguish the pilot. Relighting or cleaning the pilot helps maintain ignition.
Safety Precautions Before Repairs
Before starting any repair on your Atwood water heater that won’t ignite, safety must come first. Working with gas and electrical parts can be risky. Taking the right precautions protects you and your home. Follow these steps carefully to avoid accidents.
Turn Off Gas And Power
Always shut off the gas supply before touching the heater. Gas leaks can cause fires or explosions. Also, switch off the power to prevent electrical shocks. Confirm both gas and electricity are off before you begin repairs.
Ventilate The Area
Open windows and doors to let fresh air in. Proper ventilation helps remove gas fumes from the space. This lowers the risk of inhaling harmful gases or triggering a fire. Keep the area well-ventilated throughout the repair process.
Use Protective Gear
Wear gloves to protect your hands from sharp edges and hot parts. Safety glasses shield your eyes from dust and debris. Dress in long sleeves to avoid skin contact with chemicals or hot surfaces. Safety gear reduces injury risks during repairs.
Step-by-step Ignition Troubleshooting
Troubleshooting an Atwood water heater that won’t ignite requires a clear, simple approach. Follow these steps carefully to find the cause. Each step focuses on a key part of the ignition system.
Take your time. Work safely. These checks help you spot common problems fast. This guide uses easy words and clear instructions.
Check The Pilot Light
First, look for the pilot light. It should be burning steadily and blue. If it is out, try to relight it following the heater’s instructions. A weak or yellow flame can mean dirt or gas issues.
Inspect The Thermocouple
The thermocouple senses the pilot flame and controls the gas flow. Check if it is dirty or loose. Clean it gently with a soft cloth. Tighten the connection if it feels loose. Replace it if damaged.
Test The Igniter
The igniter sparks to light the pilot. Press the igniter button and watch for a spark. No spark means the igniter may be faulty or the batteries are dead. Replace or fix the igniter as needed.
Examine Gas Valves
Gas valves control the fuel flow to the heater. Check if the valve is fully open. Look for signs of damage or leaks. Turn the valve off before inspecting closely. Call a professional if you smell gas or find problems.

Cleaning And Maintenance Tips
Cleaning and maintaining your Atwood water heater helps keep it working well. Dirt and dust can stop the heater from lighting. Regular care can prevent many common problems. Follow these simple steps to keep your heater safe and efficient.
Remove Dust And Debris
Dust and debris can block parts of your water heater. Use a soft brush or cloth to clean around the heater. Pay attention to vents and areas near the burner. Keep the space around the heater clear to allow air flow. This helps the heater ignite properly.
Clean The Pilot Assembly
The pilot assembly lights the burner. Dirt can block the flame or gas flow. Turn off the heater and let it cool. Use a small brush or compressed air to clean the pilot area. Make sure the pilot flame is steady and blue. A weak or yellow flame means cleaning is needed.
Clear Blocked Vents
Blocked vents stop fresh air from reaching the burner. Check vents for leaves, dirt, or nests. Clear any blockage with a brush or vacuum. Proper air flow helps the heater ignite safely. Keep vents clean to avoid dangerous gas build-up.
When To Call A Professional
Knowing when to call a professional for your Atwood water heater is important. Some problems need expert help to keep you safe and to fix the issue right. Trying to fix serious problems alone can be risky and may cause more damage.
Signs Of Gas Leaks
A gas smell near the water heater is a clear warning. Gas leaks can cause fire or explosion. If you notice a rotten egg smell, do not try to fix it yourself. Leave the area and call a professional immediately. They have the tools to find and stop leaks safely.
Persistent Ignition Problems
If your water heater does not ignite after several attempts, a simple reset may not help. Constant failure to light may mean a deeper problem with the burner or gas supply. A professional can diagnose and fix ignition issues to prevent future breakdowns.
Complex Electrical Issues
Water heaters with electrical components can have wiring or control board problems. These issues require special knowledge and equipment to repair. Handling electrical parts without training is dangerous. A certified technician will ensure your heater works safely and efficiently.
