Common Causes
Gas supply problems can stop your heater from lighting. Make sure the gas valve is open. Check if the gas line is kinked or blocked. Sometimes, gas meters or regulators might have faults. Ensure the gas pressure is correct. Low pressure can prevent the heater from working. Inspect the gas connections for any leaks. Use a soapy water solution to detect leaks. If bubbles form, there is a leak. Call a professional if you suspect a gas leak.
The pilot light might be dirty or clogged. Clean the pilot orifice with a needle. Make sure the thermocouple is working. The thermocouple should be tight and in position. A faulty thermocouple might need replacing. Sometimes, drafts can blow out the pilot light. Ensure the pilot light flame is blue and steady. A yellow or unsteady flame indicates an issue.
Safety Precautions
Always turn off the gas supply before working on the water heater. This prevents gas leaks and accidents. Locate the gas shut-off valve near the heater. Turn it clockwise to close it. Check for any gas smell. Ensure the area is safe before proceeding. Use a gas detector if available. Safety first!
Proper ventilation is crucial while working on a water heater. Open windows and doors to allow fresh air in. Avoid working in confined spaces. A well-ventilated area reduces the risk of gas build-up. Use fans if necessary to improve air circulation. Ensure that vent pipes are not blocked. Good ventilation keeps you safe.
Checking Gas Supply
Experiencing issues with your Reliance water heater lighting up? Ensure the gas supply is securely connected and turned on.
Inspect Gas Valve
Make sure the gas valve is in the “on” position. Turn it counter-clockwise to open. Look for any signs of damage or wear. If damaged, replace the valve. Check if the valve is clogged. Clean it with a soft brush. Ensure there is no gas leak around the valve. Smell for gas and listen for a hissing sound. A working gas valve is crucial.
Check Gas Line
Ensure the gas line is connected properly. Look for any kinks or bends. These can block gas flow. Make sure the gas line is not damaged. Inspect for any wear or tear. A leak detector can help find leaks. Always ensure gas lines are secure and tightened well. This will help in proper gas supply to the heater.
Pilot Light Inspection
Find the pilot light on your Reliance water heater. It is usually near the bottom. Look for a small metal tube. This tube supplies gas to the pilot light. You might need a flashlight to see it clearly. Make sure the area is well-lit.
Inspect the pilot light area for any blockages. Dirt and debris can block the gas flow. Use a small brush to clean the area. Ensure there are no obstructions in the metal tube. A clean pilot light area is essential for ignition.
Thermocouple Issues
A faulty thermocouple can cause your water heater to stop working. Use a multimeter to test the thermocouple. Set the multimeter to millivolts. Place one probe on the thermocouple’s copper tube and the other on its end. Heat the thermocouple with a lighter. The multimeter should read 25 to 30 millivolts. Replace it if the reading is low.
Turn off the gas supply before starting. Remove the burner assembly to access the thermocouple. Unscrew the thermocouple nut from the gas valve. Install the new thermocouple by screwing it into place. Reassemble the burner and turn on the gas. Test the water heater to ensure it lights.
Igniter Problems
Reliance water heater not lighting often points to igniter problems. Check the igniter for dirt or damage to resolve issues.
Testing Igniter
First, check the igniter for any visible damage. Look for cracks or breaks. If the igniter looks fine, use a multimeter to test it. Set the multimeter to the lowest resistance setting. Touch the probes to the igniter terminals. A good igniter will show a reading between 10 and 20 ohms. If the reading is outside this range, the igniter is bad.
Replacing Igniter
To replace the igniter, turn off the gas supply. Disconnect the power to the water heater. Remove the burner access panel. Locate the igniter and disconnect the wires. Unscrew the old igniter. Install the new igniter and reconnect the wires. Replace the burner access panel. Turn the gas supply back on. Reconnect the power to the water heater. Test the new igniter to ensure it works.
Cleaning Burner Assembly
Cleaning the burner assembly can resolve issues with a Reliance water heater that won’t light. Ensure all components are free from debris to maintain proper functionality.
Removing Debris
Turn off the gas supply first. Locate the burner assembly under the heater. Use a wrench to remove the burner. Check for any debris or dirt. Use a brush to clean off any debris. Make sure the burner ports are clear. Also, inspect the burner for any damage. Replace if necessary. Clean the surrounding area thoroughly.
Reassembling Burner
After cleaning, place the burner back in its position. Secure it with the screws you removed earlier. Ensure all connections are tight. Turn the gas supply back on. Light the pilot light carefully. Observe the flame to ensure it’s steady. Make sure everything is secure and safe. Now, your heater should work fine.
