bradford white water heater pilot light will not stay lit
A flickering or non-igniting pilot light on your Bradford White water heater can be frustrating. Before calling for service, try these basic checks to identify the problem and potentially resolve it yourself. Safety first⁚ always turn off the gas supply before attempting any repairs.
Inspecting the Thermocouple
The thermocouple is a crucial safety device; it senses the pilot flame and keeps the gas flowing. A faulty thermocouple is a common reason for a pilot light that won’t stay lit. Carefully examine the thermocouple for any visible damage such as cracks, bends, or corrosion. A dirty thermocouple can also impede its function. Use a wire brush or fine sandpaper to gently clean the thermocouple, ensuring you don’t damage its delicate tip. If the thermocouple appears damaged beyond simple cleaning, replacement is necessary. Remember to always disconnect the gas supply before handling any components. A damaged or dirty thermocouple prevents the gas valve from staying open, resulting in the pilot flame extinguishing. Replacing the thermocouple requires careful attention to detail to ensure proper installation and gas safety. Consult your water heater’s manual or a qualified technician if you are unsure about this process.
Checking the Gas Supply
An insufficient gas supply is another frequent culprit behind a pilot light that refuses to stay ignited. Begin by checking the main gas valve to your home; ensure it’s fully open. Look for any signs of a gas leak near the water heater, such as a hissing sound or the smell of gas. If you detect a gas leak, immediately turn off the gas supply and contact your gas company or a qualified plumber. Inspect the gas line connecting to the water heater for any kinks, blockages, or damage. A restricted gas flow can prevent the pilot light from staying lit. If the gas line appears compromised, professional assistance is needed. Never attempt repairs involving gas lines unless you are a qualified professional; improper handling can lead to serious safety hazards. A simple check of the gas supply can often quickly resolve the issue, but always prioritize safety.
Examining the Pilot Assembly
The pilot assembly itself might be the source of your problem. Carefully inspect the pilot burner and its surrounding components for any signs of damage, debris, or misalignment. Look for cracks or holes in the burner tube, as these can disrupt the gas flow and prevent proper ignition. Check the pilot light itself; if it’s significantly corroded or damaged, it may need replacement. The pilot assembly often includes a small screen or filter that can become clogged with dust or debris, impeding gas flow. Gently clean this screen (if present) with a soft brush or compressed air. If you notice any significant damage to the pilot assembly, it’s best to consult a professional for repair or replacement. Improper handling of the pilot assembly could lead to gas leaks or further damage. Remember to always turn off the gas supply before attempting any inspection or cleaning.
Cleaning the Burner and Orifice
A clogged burner or orifice can significantly hinder gas flow, preventing the pilot light from staying lit. Locate the burner assembly and the small orifice where the gas exits. Use a soft brush, such as a wire brush or a toothbrush, to gently remove any dust, dirt, cobwebs, or mineral deposits that may have accumulated. Be cautious not to damage the delicate parts of the burner assembly. For stubborn clogs, compressed air can be effective in clearing the orifice, but use it sparingly to avoid damaging the delicate components. After cleaning, carefully inspect the burner and orifice for any signs of damage or wear. If you notice any significant corrosion, cracks, or obstructions, it might be necessary to replace the affected parts. Remember to always turn off the gas supply before attempting any cleaning or maintenance. Improper cleaning can lead to gas leaks or further damage, so proceed with caution.
