Your Guide to a Consistently Lit Gas Hot Water Heater

We’ve all been there – standing in the shower, shivering as the hot water runs cold. If your gas hot water heater won’t stay lit, it can be incredibly frustrating. But don’t worry, I’ve got you covered!

Troubleshooting a Gas Hot Water Heater That Won’t Stay Lit

Let’s start by understanding why your gas hot water heater keeps going out. There could be a few different culprits at play here. First, check the pilot light – if it’s out, that’s likely the root cause. A faulty thermocouple, which monitors the pilot light, could also be to blame. Other potential issues include a malfunctioning gas control valve, a blocked air supply, sediment buildup in the tank, or even a faulty gas supply line.

Before we dive into the nitty-gritty, let me emphasize the importance of safety. If you smell gas or suspect a leak, evacuate the area immediately and contact a professional. Gas leaks can be incredibly dangerous, and your safety should always come first. Never attempt to repair a gas hot water heater yourself if you’re inexperienced or unsure.

Common Reasons Why Your Gas Hot Water Heater Keeps Going Out

Now, let’s take a closer look at some of the most common reasons why your gas hot water heater won’t stay lit:

Step-by-Step Guide to Relighting a Gas Hot Water Heater

If your gas hot water heater won’t stay lit, try following these steps to relight it:

  1. First, locate the gas control valve (usually a knob or lever) and turn it to the “OFF” position. This will cut off the gas supply to the pilot light and burner.
  2. Next, remove the outer door or panel to access the pilot light assembly. You may need a screwdriver or other tools to remove the access panel.
  3. Look for the pilot light tube and follow it to the pilot light opening. Use a long match or a barbecue lighter to relight the pilot light. You may need to hold down the pilot light button or lever while relighting.
  4. Once the pilot light is lit, hold down the reset button on the gas control valve for 30 seconds to 1 minute. This will allow the thermocouple to heat up and signal that the pilot light is on.
  5. Finally, turn the gas control valve to the “ON” position and make sure the pilot light stays lit. You may need to adjust the gas control valve to maintain the proper flame size.

If you’ve followed these steps and the pilot light still won’t stay lit, it’s time to call in a professional. They can diagnose and repair any underlying issues with your gas hot water heater, such as a faulty thermocouple, gas control valve, or gas supply line.
