Rheem Water Heater Igniter Won’t Spark: Causes and Solutions

If you own a Rheem water heater, you rely on it to provide hot water for daily activities such as showering, cooking, and cleaning. However, what happens when your Rheem water heater igniter won’t spark? In this article, we’ll explore the causes of this issue and provide some solutions to help you get your water heater working again.

Introduction

Rheem water heaters are known for their quality and dependability, but like any appliance, they can experience problems from time to time. One common issue that homeowners face is when the igniter won’t spark. The igniter is a critical component of the water heater, responsible for lighting the gas that heats the water. When the igniter fails, you won’t have hot water until the problem is resolved.

 What is a Rheem Water Heater Igniter?

A Rheem water heater igniter is a small device that creates a spark to ignite the gas that heats the water. It is located near the bottom of the water heater tank and is connected to the ignition control module. When the igniter receives a signal from the ignition control module, it generates a spark that ignites the gas.

Common Causes of Igniter Failure

There are several reasons why a Rheem water heater igniter may fail to spark. Let’s take a closer look at some of the most common causes:

Dirty Igniter

Over time, the igniter can become dirty, which can prevent it from sparking. Dirt, dust, and other debris can accumulate on the surface of the igniter, creating a barrier that prevents it from creating a spark.

Faulty Igniter

If the igniter is faulty, it won’t be able to create a spark. A faulty igniter may be due to a damaged electrode or a cracked ceramic insulator. In some cases, the igniter may need to be replaced.

Ignition Control Module Failure

The ignition control module is responsible for sending a signal to the igniter to create a spark. If the ignition control module fails, the igniter won’t receive the signal, and it won’t spark.

Gas Supply Issues

If there is a problem with the gas supply, the water heater won’t be able to heat the water. Gas supply issues can include problems with the gas valve, a gas leak, or low gas pressure.

Other Possible Causes

Other possible causes of igniter failure include a faulty thermocouple, a malfunctioning temperature sensor, or a clogged burner.

How to Troubleshoot a Rheem Water Heater Igniter

If you suspect that your Rheem water heater igniter isn’t sparking, there are a few troubleshooting steps you can take:

Turn off the Power

Before you begin any troubleshooting, it’s important to turn off the power to the water heater. This can be done by switching off the circuit breaker or unplugging the water heater.

Inspect the Igniter

Carefully inspect the igniter for any signs of damage or debris. If you notice any dirt or debris on the igniter, use a soft-bristled brush to gently clean it. Avoid using any abrasive materials that could damage the igniter.

Check the Gas Supply

Make sure that the gas valve is turned on and that there are no gas leaks. If you suspect a gas leak, leave the area immediately and call a professional.

Test the Ignition Control Module

Use a multimeter to test the ignition control module. Follow the manufacturer’s instructions for testing the module. If the module is faulty, it will need to be replaced.

Steps to Replace a Rheem Water Heater Igniter

If you’ve determined that the igniter needs to be replaced, follow these steps:

Turn off the Power

As with any electrical repair, it’s essential to turn off the power before starting work. Switch off the circuit breaker or unplug the water heater.

Access the Igniter

Remove the access panel from the water heater to access the igniter. The access panel is usually located near the bottom of the water heater.

Remove the Old Igniter

Carefully remove the old igniter from its housing. Depending on the model of your water heater, the igniter may be held in place by screws or clips.

Install the New Igniter

Install the new igniter in the housing and secure it in place. Follow the manufacturer’s instructions for your specific model.

Conclusion

In conclusion, a Rheem water heater igniter that won’t spark can be a frustrating problem, but it’s one that can be resolved with some troubleshooting and, if necessary, replacement of the igniter or ignition control module. By following the steps outlined in this article, you should be able to get your water heater up and running again in no time.
