Inspecting The Pilot Light
If your RV water heater is not working on gas, it may be a pilot light issue. The pilot light is a small flame that ignites the gas burner. If it goes out, the water heater will not work. Inspecting the pilot light involves a few simple steps.
Locating The Pilot Light
First, find the pilot light. It is usually near the bottom of the water heater. Look for a small panel or door, which covers the pilot light. Remove this panel carefully.
Inside, you will see a small burner. The pilot light is a tiny flame at the end of a small tube. It is essential to know its exact location for the next steps.
Cleaning The Pilot Light
Dirt or debris can block the pilot light. Use a soft brush or compressed air to clean it. Be gentle to avoid damage.
Next, check the area around the pilot light for any blockages. Ensure nothing is obstructing the flame. Even small particles can cause problems.
After cleaning, try to relight the pilot light. Follow your RV water heater’s manual for specific instructions. Usually, you need to press and hold a button while lighting the flame.
If the pilot light stays on, your problem is solved. If not, further inspection may be needed.
By locating and cleaning the pilot light, you can often fix common issues. This simple inspection can save time and money.
Checking The Thermocouple
If your RV water heater is not working on gas, one of the key components to check is the thermocouple. The thermocouple is a safety device that detects if the pilot light is on. If it fails, the gas valve will not open, and your water heater will not work.
