=Water heaters are an essential part of any household, providing warmth and comfort in colder seasons. A pilot light is a fundamental component of a water heater, responsible for igniting the burner that heats the water. Unfortunately, pilot issues like a pilot light that won't light can arise, leading to cold showers and frustration. In this article, we'll explore some troubleshooting tips and solutions to fix a water heater pilot that won't light.
A common reason why the pilot light won't light is a gas supply problem. Ensure that the gas supply to your water heater is on. If you're unsure about this, contact a qualified gas technician to avoid dangerous gas leaks. If you smell gas or suspect a gas leak, leave the area immediately and call the gas company.
The pilot orifice and the thermocouple are two essential components of the water heater responsible for the pilot light ignition. A dirty pilot orifice and a malfunctioning thermocouple can prevent the pilot from lighting. It's essential to clean them regularly, preferably annually, to avoid pilot light issues. Ensure that the pilot orifice is clear of debris or soot by using a small wire or needle to clean it. Use fine-grit sandpaper to rub off corrosion on the thermocouple. If cleaning doesn't work, contact a professional plumber to repair or replace these parts.
The pilot light flame should cover the thermocouple adequately. If it doesn't, adjust the pilot flame height by using the control valve. Turn off the gas supply, remove the cover panel, and locate the control valve. Using a screwdriver, turn the valve to adjust the flame size as per your water heater's guidelines. Ensure that the flame doesn't flicker or go out when you release the control valve. Do not increase the flame height above the recommended size as it can lead to dangerous gas leaks and fire hazards.
Another potential reason why the pilot light won't light is faulty wiring or an igniter system. Inspect the wire connections to ensure they're tight and secure. You can use a multimeter to test the voltage supply to the igniter system. If the voltage supply meets the manufacturer's requirements, and there's no spark, it could mean that the igniter system is failing. In this case, contact a professional plumber to inspect and repair the wiring or igniter system.
A water heater pilot that won't light can be frustrating, but with the above troubleshooting tips and solutions, you'll be able to resolve the issue and get your water heater back to optimal working condition. Regular maintenance and inspection of your water heater can prevent pilot light issues from arising. However, if the above solutions don't work or you're unsure about fixing the issue, contact a trusted and professional plumber to help you out.
