Common Causes Of A Water Heater Not Staying Lit
Water heaters that do not stay lit cause frustration and cold showers. Several common issues cause this problem. Understanding these causes helps in fixing the heater or knowing when to call a professional. The following sections explain the main reasons a Suburban water heater won’t stay lit.
Thermocouple Issues
The thermocouple acts as a safety device. It senses the pilot flame and allows gas flow. A faulty or dirty thermocouple stops gas flow. This causes the pilot light to go out quickly. Checking and cleaning the thermocouple often solves the problem.
Dirty Pilot Assembly
Dust and debris build up in the pilot assembly. This blocks gas flow and weakens the flame. A weak flame cannot keep the heater lit. Cleaning the pilot assembly restores a strong flame and steady operation.
Gas Supply Problems
Low or interrupted gas supply stops the pilot light. Issues like closed valves or leaks reduce gas flow. Ensuring the gas supply is steady and valves are open solves this cause. A professional should check for gas leaks immediately.
Faulty Gas Control Valve
The gas control valve regulates gas to the burner and pilot. If the valve is faulty, it may cut off gas unexpectedly. This causes the flame to go out. Replacing a bad gas control valve often fixes the problem completely.

Safety Precautions Before Repairs
Before fixing a Suburban water heater that won’t stay lit, safety is key. Water heaters use gas and fire, which can be risky. Taking safety steps helps stop accidents and injuries. Always prepare well before starting any repair work.
Shutting Off Gas Supply
Turn off the gas supply to the water heater first. This stops gas from leaking while you work. Locate the gas valve near the heater. Twist it to the off position. Double-check that no gas smells around the heater before you continue.
Ventilation Tips
Work in a well-ventilated area. Open windows and doors to let fresh air in. Good airflow clears out any leftover gas. It also helps prevent harmful fumes from building up. Never work in a closed or tight space.
Using Proper Tools
Use the right tools for the job. This makes repairs safer and easier. Avoid using worn or damaged tools. Have a wrench, screwdriver, and flashlight ready. Proper tools help you work carefully and avoid mistakes.
Step-by-step Quick Fixes
Suburban water heaters sometimes fail to stay lit. Quick fixes can often solve this problem without calling a technician. These simple steps help find and fix the issue fast. Follow the instructions carefully for safety and best results.
Cleaning The Pilot Assembly
Start by turning off the gas supply. Wait for the water heater to cool down completely. Remove the access panel to reach the pilot assembly. Use a soft brush to clean dust and dirt. Clear any blockages in the pilot tube. Reassemble the parts and turn on the gas. Light the pilot to check if it stays lit.
Replacing The Thermocouple
The thermocouple senses the pilot flame. A faulty one causes the heater to shut off. Turn off the gas supply before starting. Disconnect the old thermocouple from the gas valve. Unscrew it gently from the pilot bracket. Install a new thermocouple in the same place. Tighten all connections securely. Turn the gas back on and test the pilot light.
Checking And Adjusting Gas Pressure
Low or high gas pressure affects the pilot flame. Use a manometer to measure gas pressure. Compare the reading with the manufacturer’s instructions. Adjust the gas regulator if needed. Increase or decrease pressure carefully. Avoid setting pressure outside safe limits. After adjustment, relight the pilot and observe the flame stability.
Inspecting And Resetting The Gas Valve
The gas valve controls gas flow to the heater. Turn off the gas and power supply first. Remove the valve cover to inspect for damage or dirt. Clean the valve area using a dry cloth. Press the reset button on the valve if available. Wait a few minutes before turning the gas back on. Light the pilot to check if it stays lit now.

When To Call A Professional
Knowing when to call a professional for your Suburban water heater is important. Some problems need expert help to keep your home safe. Trying to fix serious issues alone can be risky and cause more damage.
Watch for signs that the problem is beyond simple fixes. A trained technician has the tools and knowledge to find and fix tough problems fast. Here are key signs that mean you should call a professional right away.
Signs Of Major Gas Leaks
A strong smell of gas near your water heater is dangerous. Gas leaks can cause fires or explosions. If you notice a hissing sound or dead plants near the heater, leave the area immediately. Call a professional to inspect and repair the leak. Do not try to fix gas leaks yourself.
Persistent Ignition Failures
Your water heater should light quickly and stay lit. If it keeps failing to ignite despite relighting attempts, a deeper problem exists. This could be a faulty thermostat or gas valve. A professional can diagnose the issue and replace parts safely. Avoid using the heater until it is fixed.
Complex Electrical Issues
Electrical problems can cause the heater to stop working or become unsafe. Flickering lights or tripped breakers linked to the water heater need attention. Damaged wiring or control boards require expert repair. Handling electrical parts without training is unsafe. Contact a technician to solve these issues.
Maintenance Tips To Prevent Future Issues
Keeping your Suburban water heater working well means regular care. Small checks can stop big problems. Follow these easy maintenance tips to keep the pilot light lit and your heater running smoothly.
Routine care helps avoid costly repairs and keeps your water warm without interruption.
Regular Pilot Light Cleaning
Clean the pilot light area often. Dust and dirt can block the flame. Use a soft brush or compressed air to clear debris. A clean pilot light burns steady and bright. This simple step can stop many lighting problems early.
Annual Gas Line Inspections
Check gas lines once a year. Look for leaks or damage that can affect the heater’s performance. Hire a professional to inspect and fix any issues. Safe gas lines keep your heater running safely and reliably.
Thermocouple Testing Schedule
Test the thermocouple regularly. This small part tells the heater to stay lit. If it fails, the pilot light goes out. Check it every six months and replace it if needed. This keeps your heater working without interruptions.
