Rv Water Heater Igniter Not Clicking

RV Water Heater Igniter Not Clicking | Troubleshooting Guide

One of the most common issues faced by RV owners is when the water heater igniter fails to click, preventing the water heater from functioning properly. This can be frustrating, especially when you’re out on a camping trip and in need of hot water. In this article, we will discuss the possible causes of this problem and provide a step-by-step troubleshooting guide to help you resolve the issue.

Possible Causes of Igniter Failure:

Before we dive into troubleshooting, it’s essential to understand the potential reasons why your RV water heater’s igniter is not clicking. By identifying the root cause, you can effectively resolve the issue. Here are some common causes:

  • Dead Batteries: The most common cause of a non-clicking igniter is dead batteries. If your water heater runs on a battery-powered ignition system, check the battery levels and replace them if necessary.
  • Defective Igniter Electrode: Over time, the igniter electrode can become coated with carbon or other debris, preventing it from creating a spark. A faulty igniter electrode may need to be cleaned or replaced.
  • Gas Supply Issues: Insufficient gas supply or a malfunctioning gas valve can also prevent the igniter from clicking. Ensure that the gas supply to the water heater is turned on and there are no leaks in the system.
  • Control Board Malfunction: If none of the above solutions work, it’s possible that the control board of your RV water heater is faulty. This typically requires professional assistance for diagnosis and repair.

Troubleshooting Steps:

Now that you have an idea of what might be causing the non-clicking igniter issue, let’s proceed with the troubleshooting steps:

Step Action
1 Check the battery levels and replace if necessary. Ensure the battery connections are secure.
2 Inspect the igniter electrode for any carbon deposits or debris. Gently clean the electrode using a wire brush or sandpaper.
3 Verify the gas supply is turned on and check for any leaks in the gas system. Contact a professional if you suspect a gas supply issue.
4 If the igniter still doesn’t click, it may be necessary to replace the igniter electrode. Consult your RV’s manual for specific instructions on how to do this.
5 If all else fails, it’s recommended to seek professional help to inspect the control board and other electrical components of the water heater.

Preventing Future Issues:

Once you have resolved the igniter problem, it’s important to take preventive measures to avoid facing similar issues in the future. Here are a few tips:

  • Regularly inspect and clean the igniter electrode to prevent carbon buildup.
  • Ensure the battery used for the ignition system is always in good condition and replace it as needed.
  • Regularly check the gas supply and look for any signs of leaks.
  • Follow the manufacturer’s guidelines for maintenance and operation of your water heater.

By following these preventive measures, you can minimize the chances of your RV water heater igniter failing in the future.
