An RV hot water heater not igniting can be frustrating. You need hot water for showers and washing dishes, especially on long trips.
Understanding why your RV hot water heater isn’t igniting is crucial. It can be a simple fix or something more complex. This guide will help you identify common issues and solutions. Whether it’s a gas or electric heater, we’ll cover the basics.
You’ll learn about safety precautions too. Knowing what to check can save you time and money. Let’s dive into the common reasons your RV hot water heater might not be working.
Common Causes
Experiencing an RV hot water heater that won’t ignite can be frustrating. Understanding the common causes can help you troubleshoot the issue effectively. Let’s explore some typical reasons behind this problem.
Empty Propane Tank
An empty propane tank is a common culprit. Your hot water heater relies on propane to ignite. If the tank is empty, there’s no fuel to start the heater. Check your propane gauge. Refill the tank if it’s empty. This simple check can save you a lot of trouble.
Faulty Thermocouple
A faulty thermocouple can also prevent ignition. The thermocouple is a safety device. It detects the pilot light and allows gas to flow. If it’s defective, it won’t detect the flame. As a result, it shuts off the gas supply. Inspect the thermocouple for damage. Replace it if necessary.

Preliminary Checks
Ensuring your RV hot water heater ignites properly can be challenging. To troubleshoot, start with some preliminary checks. These simple steps can often identify and resolve issues quickly.
Check Gas Supply
First, confirm the gas supply is turned on. Make sure there is enough propane in the tank. Inspect the gas line for any kinks or blockages. If the gas supply seems fine, proceed to the next check.
Inspect Electrical Connections
Next, examine the electrical connections of the heater. Ensure all wires are securely connected. Check for any signs of wear or corrosion. A loose or corroded wire can prevent the heater from igniting.
| Check | Details |
|---|---|
| Gas Supply | Ensure gas is on and lines are clear. |
| Electrical Connections | Verify wires are secure and free of corrosion. |
By performing these preliminary checks, you can often identify the issue with your RV hot water heater. If these steps do not resolve the problem, further troubleshooting may be required.
Resetting The Heater
If your RV hot water heater is not igniting, a reset may help. Sometimes, heaters need a little push to get going again. Resetting the heater can solve many issues quickly. Let’s walk through the process of resetting your RV hot water heater.
Locate The Reset Button
First, you need to find the reset button. This button is usually red and located on the control panel of the water heater. Check your RV’s user manual if you have trouble finding it. The manual will have detailed diagrams to assist you.
Proper Reset Procedure
Once you have located the reset button, follow these steps to reset the heater:
- Turn off the power supply to the heater.
- Wait for a few minutes to ensure all power is drained.
- Press and hold the reset button for 5-10 seconds.
- Release the button and turn the power back on.
- Wait for the heater to complete its ignition cycle.
If the heater still does not ignite, you might need to check other components. Ensure there is enough gas supply and that the igniter is functioning well. Resetting the heater is often the first step in troubleshooting ignition issues. It is simple and can be done quickly.
Cleaning The Burner
Having trouble with your RV hot water heater not igniting? Cleaning the burner could be the solution. A dirty burner can block the ignition process. Regular cleaning ensures your heater functions well.
Access The Burner
First, turn off the gas supply. Ensure the heater is cool. Locate the burner assembly near the bottom of the heater. Remove the access panel. You may need a screwdriver.
Cleaning Steps
Once the burner is accessible, inspect it for debris. Use a soft brush to clean the surface. Remove any visible dirt or rust. A can of compressed air can help. Blow air through the burner holes. This removes small particles. Be gentle to avoid damage.
Check the burner tube. Ensure it is clear. Blockages can cause ignition failure. If needed, use a small, flexible brush. Clean the inside of the tube carefully.
After cleaning, reassemble the burner. Replace the access panel. Turn the gas supply back on. Test the heater. It should ignite smoothly now.
Inspecting The Igniter
Your RV hot water heater not igniting can be frustrating. A common cause is a faulty igniter. Let’s focus on inspecting the igniter to see if it’s the root of the issue.
Visual Inspection
Begin by turning off the power to your hot water heater. Carefully remove the access panel. Look for any visible damage to the igniter. Check for cracks, dirt, or debris around it. A dirty or damaged igniter won’t spark properly.
Testing For Spark
Restore power to the heater. Set the heater to ignite. Observe the igniter. You should see a small, blue spark. No spark means the igniter may be faulty. If you see a weak spark, it may not be strong enough to ignite the gas.

Checking The Thermocouple
Experiencing issues with your RV hot water heater not igniting? The thermocouple might be the culprit. This small, yet crucial, component ensures the gas valve only opens when the pilot light is on. Let’s dive into how you can check this important part.
Thermocouple Location
First, you need to locate the thermocouple. It is usually near the pilot light. Look for a thin, metal tube connected to the gas valve. The thermocouple’s tip sits in the flame of the pilot light. This placement allows it to detect heat and signal the gas valve to open.
Testing And Replacement
Testing the thermocouple is straightforward. Use a multimeter set to millivolts. Disconnect the thermocouple from the gas valve. Place one probe on the thermocouple’s end and the other on the tube. Light the pilot and wait for a reading. A functional thermocouple should read between 25 to 30 millivolts.
If the reading is lower, the thermocouple needs replacement. To replace it, first, turn off the gas. Remove the old thermocouple by unscrewing it from the gas valve. Install the new thermocouple by reversing the removal steps. Ensure it sits properly in the pilot light flame.
Once replaced, test the system. Light the pilot and check if the water heater ignites. This simple fix can restore your RV’s hot water heater functionality.
Examining The Control Board
Your RV hot water heater not igniting can be frustrating. The control board plays a vital role in the ignition process. It manages the electrical signals that ignite the heater. Any malfunction here can prevent your heater from working. Let’s look at some common signs of damage and how to replace the control board.
Signs Of Damage
Inspecting your control board can help diagnose the issue. Look for these signs of damage:
- Burnt or melted components
- Corrosion on connections
- Loose or broken wires
- Visible cracks on the board
A damaged control board can cause your RV hot water heater to fail. Regular checks can prevent sudden failures.
Replacement Guide
Replacing the control board is straightforward. Follow these steps:
- Turn off the power supply to the heater.
- Remove the cover of the control board compartment.
- Carefully disconnect all wires from the old control board. Note their positions.
- Remove the screws holding the control board in place.
- Take out the old control board.
- Install the new control board in the same position.
- Screw the new board in place.
- Reconnect all wires to the new control board.
- Replace the cover of the control board compartment.
- Turn the power supply back on and test the heater.
Ensure all connections are secure to avoid future issues. A properly functioning control board ensures your heater ignites reliably.
