Water Heater Pilot Light Goes Out Cold Weather

Cold weather can cause the water heater pilot light to go out. This often happens due to drafts or insufficient insulation.

During the winter months, maintaining a water heater becomes crucial. Cold weather can lead to the pilot light going out, which disrupts hot water supply. Drafts and poor insulation around the heater are common culprits. Ensuring proper insulation and sealing any drafts can prevent this issue.

Regular maintenance and timely checks can keep the heater functioning efficiently. Consider using a water heater blanket for added insulation. Understanding these simple steps helps in keeping your water heater operational during cold weather. Proper care can save you from unexpected cold showers and potential repair costs.

Common Causes

Cold weather can cause a water heater pilot light to go out due to drafts or increased condensation. Ensure proper insulation around the heater to prevent this issue.

Thermocouple Issues

The thermocouple is a safety device. It checks if the pilot light is on. A dirty thermocouple can stop working. This makes the pilot light go out. Cleaning the thermocouple can solve this problem. Sometimes, the thermocouple gets bent or broken. It needs replacing if damaged.

Pilot Orifice Blockage

The pilot orifice is a small opening. It lets gas flow to the pilot light. Dust and debris can block this opening. This stops the pilot light from staying lit. Cleaning the orifice helps the gas flow properly. A thin wire or needle can be used for this task.

Impact Of Cold Weather

Cold weather can be a problem for water heaters. The pilot light often goes out. Low temperatures make the gas harder to ignite. Cold air can cool the flame quickly. This leads to frequent pilot light outages. Regular checks can help prevent this issue.

Windy days can also affect your water heater. Strong winds can blow out the pilot light. Wind gusts can enter through vents or gaps. This makes the flame unstable. Ensuring proper ventilation and sealing gaps can reduce this problem. Regular maintenance is key to keeping the pilot light on.

Diagnosing The Problem

Check the pilot light for any visible issues. Look for debris or dust around the pilot area. Ensure the flame is blue and steady. A yellow flame may indicate a problem. Inspect the gas supply to ensure it’s turned on. Make sure the thermocouple is positioned correctly.

The thermocouple is a safety device. It shuts off the gas if the pilot light goes out. Use a multimeter to test the thermocouple. Disconnect the thermocouple from the gas valve. Set the multimeter to millivolts. Attach the multimeter leads to the thermocouple ends. Heat the thermocouple with a lighter. The reading should be 25 to 30 millivolts. Replace the thermocouple if the reading is low.

Safety Precautions

Cold weather often causes water heater pilot lights to go out. Ensure safety by relighting the pilot according to the manufacturer’s instructions. Regular maintenance can prevent unexpected outages.

Gas Leak Checks

Always check for a gas leak first. Use a gas detector or soapy water. Bubbles mean there is a leak. Call a professional if you find a leak. Never use open flames to check for gas.

Proper Ventilation

Ensure the room has proper ventilation. Poor ventilation can cause gas buildup. Open windows or use fans to improve airflow. Clear any blockages from vents. Good air circulation is key for safety.

Relighting The Pilot Light

First, locate the pilot light on your water heater. Turn the gas valve to the “off” position. Wait five minutes to clear out any gas. After waiting, switch the gas valve to the “pilot” setting. Hold down the reset button and bring a lighter to the pilot light opening. Keep the button pressed for one minute after the pilot light ignites. Release the button and turn the gas valve to the “on” position.

Preventative Measures

Regular maintenance keeps your water heater running smoothly. Check the pilot light often to ensure it stays lit. Clean the burner and pilot assembly regularly. Inspect the thermocouple for any signs of wear. Replace it if needed. Make sure the gas supply is steady and clean. Schedule professional inspections annually. This helps catch problems early.

Weatherproofing protects your water heater from cold weather. Insulate the pipes to prevent freezing. Use a water heater blanket to keep the tank warm. Seal any gaps or cracks around the heater. This keeps cold air out. Ensure good ventilation to avoid moisture buildup. Proper weatherproofing extends the life of your heater.

When To Call A Professional

If the pilot light keeps going out, it might be a bigger problem. A professional can find the cause quickly. They have the right tools and experience. Fixing it yourself could make things worse. A professional will ensure your heater works safely.

Some water heater issues need complex repairs. These repairs might involve gas lines or electrical parts. It’s best to leave these jobs to professionals. They know the safety rules. They can fix your heater without risk. Professional help saves time and keeps your home safe.

Choosing A Reliable Water Heater

Choosing an energy-efficient water heater saves money and helps the environment. Many modern water heaters use less energy than older models. Look for heaters with the Energy Star label. This label means the heater meets strict energy-saving rules. Tankless water heaters are very efficient because they only heat water when needed. Heat pump water heaters use heat from the air, making them very efficient too. Consider the size of the heater. A heater too big or too small can waste energy. Regular maintenance also helps keep your heater running efficiently.

Many brands offer reliable and efficient water heaters. Rheem is known for its high-quality and durable products. AO Smith provides a variety of models with good energy ratings. Bradford White is praised for its innovative technology. Bosch offers efficient tankless water heaters. EcoSmart focuses on eco-friendly options. Navien is another brand known for its high efficiency. Compare features and customer reviews to find the best brand for your needs.
