Common Causes Of Ignition Failure
The Atwood water heater not igniting can be frustrating. Several issues cause ignition failure. Knowing these common problems helps fix the heater faster. Simple checks often solve the issue. This section explains the main causes behind ignition failure.
Thermocouple Issues
The thermocouple senses the pilot flame. It stops gas flow if the flame goes out. Dirt or damage can make it fail. A bad thermocouple stops the heater from igniting. Cleaning or replacing it often restores function.
Pilot Light Problems
The pilot light must stay lit to ignite the heater. Wind, dirt, or gas issues can put it out. A weak or flickering pilot light causes ignition failure. Cleaning the pilot area or relighting the flame can help.
Gas Supply Interruptions
The water heater needs a steady gas supply. Blocked or closed gas valves stop ignition. Gas line leaks or low pressure also cause problems. Checking and restoring gas flow is key to fixing ignition failure.
Faulty Ignition System
The ignition system creates the spark to light the gas. Faulty wiring or worn parts prevent ignition. Electrical problems can stop the heater from starting. Repairing or replacing ignition components often solves the issue.
Basic Troubleshooting Steps
Basic troubleshooting helps identify simple problems with your Atwood water heater. These steps often fix ignition issues without calling a technician. Follow these easy checks to get your water heater working again.
Checking The Pilot Light
First, check if the pilot light is lit. The pilot light is a small flame that starts the heater. Look inside the heater’s access panel. If the flame is out, try relighting it carefully. Use the instructions in your heater manual for safety.
Inspecting The Thermocouple
The thermocouple senses the pilot flame and controls gas flow. If it is dirty or damaged, the heater won’t ignite. Clean the thermocouple gently with a cloth. Replace it if it looks worn or broken. This part is cheap and easy to fix.
Ensuring Gas Supply
Check the gas valve to make sure gas flows to the heater. The valve should be fully open. If you smell gas, turn off the supply immediately and call a professional. No gas means no ignition, so this step is crucial.
Resetting The Heater
Resetting can clear minor faults in the system. Find the reset button on your heater. Press and hold it for a few seconds, then release. Wait a moment and try to ignite the heater again. This simple step often restores normal function.
Quick Fixes For Atwood Water Heater
Atwood water heaters sometimes fail to ignite. This problem can stop hot water flow and cause discomfort. Many common issues have quick fixes you can try. These fixes often save time and money. Basic tools and safety steps are all you need.
Cleaning The Pilot Orifice
The pilot orifice can get clogged with dirt or debris. This blocks gas flow and stops ignition. Turn off the gas before cleaning. Use a small brush or compressed air. Clean gently to avoid damage. Clear orifice means better gas flow and easier ignition.
Replacing The Thermocouple
The thermocouple senses heat and controls gas flow. A faulty thermocouple stops gas supply. Locate the thermocouple near the pilot light. Unscrew it carefully and remove. Replace with a new, compatible part. A working thermocouple ensures the heater ignites safely.
Relighting The Pilot Light
Sometimes the pilot light simply goes out. Relighting it can fix the problem quickly. Turn off the gas and wait a few minutes. Follow the heater’s instructions to light the pilot. Hold the button until the flame stays lit. Watch the flame to ensure it burns steadily.
Tightening Gas Connections
Loose gas connections can block gas flow or cause leaks. Check all gas line fittings and screws. Use a wrench to tighten connections gently. Avoid over-tightening to prevent damage. Secure connections improve gas flow and help the heater ignite properly.

When To Call A Professional
Knowing when to call a professional for your Atwood water heater saves time and prevents damage. Some problems need expert care. Trying to fix these issues alone can be unsafe or cause more harm.
Recognize signs that require professional help. This protects your home and ensures the heater works properly again.
Persistent Ignition Issues
If your water heater keeps failing to ignite, it is a serious sign. Repeated attempts without success mean internal parts may be damaged. A technician can diagnose and fix these problems safely. Avoid wasting gas or energy with constant restarts.
Gas Leak Concerns
Smelling gas near your water heater calls for immediate professional help. Gas leaks are dangerous and can cause fires or explosions. Professionals have the right tools to detect and repair leaks quickly. Do not try to fix gas leaks yourself.
Electrical Component Failures
Water heaters rely on electrical parts to function. If these parts fail, the heater may not ignite or work properly. Faulty wiring or damaged switches need expert repair. Handling electrical issues without training can be risky. Let a professional handle all electrical repairs.
Maintenance Tips To Prevent Ignition Problems
Keeping an Atwood water heater working well means stopping ignition problems early. Proper care helps the heater light quickly and stay safe. Simple steps keep the parts clean and functioning. These easy tips save time and money on repairs.
Regular Cleaning
Clean the burner area often. Dust and dirt can block the flame. Wipe the exterior and remove debris around the heater. A clean surface helps the ignition spark work better.
Scheduled Inspections
Check the water heater every few months. Look for signs of wear or damage. Test the ignition system to catch problems early. A quick inspection can prevent bigger issues later.
Proper Ventilation
Make sure air flows freely around the heater. Blocked vents reduce oxygen needed for ignition. Clear any obstacles near vents to keep air moving. Good ventilation supports a strong, steady flame.
Safe Operating Practices
Follow the heater’s instructions carefully. Avoid turning it on and off too fast. Use the right fuel type and keep it dry. Safe use prevents ignition failure and extends heater life.
