We’ll discuss some common reasons why a suburban RV hot water heater won’t light and provide you with some troubleshooting tips to help you get it back in working condition.

Common Causes For Suburban RV Hot Water Heater Won’t Light

Suburban RV hot water heater ignition failure may be caused by several common issues.

One possible cause is a #1 faulty propane supply, which can prevent the heater from igniting.

Another common issue is a #2 clogged burner or orifice, which can obstruct the flow of gas and prevent ignition.

Additionally, a #3 malfunctioning ignition system can lead to ignition failure. These issues can disrupt the proper functioning of the hot water heater and may require troubleshooting and repairs to resolve.

suburban water heater troubleshooting Steps To Diagnose The Problem

If your suburban RV hot water heater won’t light, start by checking the propane tank for fuel level and valve position.

Inspect the burner and orifice for any debris or blockage that may be causing the issue.

Additionally, test the ignition system functionality using a multimeter to ensure it is working properly.

These steps can help identify the root cause of the problem and guide you in resolving the issue effectively.

Solution #1: Addressing Propane Supply Issues

If your suburban RV hot water heater won’t light, there may be a problem with the propane supply.

1. Firstly, verify that the propane tank is turned on and has sufficient fuel. It’s essential to ensure there is enough propane in the tank for the water heater to function properly.

2. Next, inspect the hoses and connections for any leaks or damage. Leaks or damages can potentially impede the flow of propane, causing the heater to fail to ignite.

If any leaks or damages are found, they should be promptly repaired or the affected parts should be replaced.

If all else fails, consider replacing the propane tank if it is old or not functioning correctly.

Solution #2: Clearing Burner And Orifice Blockage

Follow these steps to clear any blockage in your suburban RV hot water heater:

1. Turn off the propane supply and let the system cool down.

2. Clean the burner and orifice using a brush or compressed air.

3. Check for any signs of rust or corrosion and address the issue if necessary.

Solution #3: Fixing Malfunctioning Ignition System

#1: Test the igniter using a multimeter to check for continuity

One common issue with a suburban RV hot water heater that won’t light up is a malfunctioning ignition system.

To determine if this is the problem, you can use a multimeter to test the continuity of the igniter. This will help you identify any issues with the ignition electrode or spark module.

#2: Replace faulty ignition electrode or spark module if necessary

If the multimeter test indicates a lack of continuity, the ignition electrode or spark module likely needs to be replaced.
