How To Troubleshoot And Reset Suburban RV Furnace?

Troubleshooting is necessary before resetting the Suburban RV furnace because some technical issues won’t be solved just by pushing the reset button. If you don’t, then the furnace might start working or might even fail to start.

Follow the instructions given and fix issues that caused the reset button to trip, and then reset it to make the Suburban RV furnace function properly.

Refill Fuel Tank

A 12V is the main power source for the Suburban RV furnace. Because if the battery is drained, the furnace will fail to ignite. So the reset button may trip when the battery is drained or out of power.

So the primary thing you need to do is check your Suburban RV furnace’s battery. Use a multimeter to measure the remaining charge.

If it’s too low and takes a long time to recharge, you need to buy a new one. If it’s working fine, recharge the battery and press the reset button.

Clean Gas Valves

Sometimes, the gas valves can be blocked or clogged due to weather conditions like rain and dust. For this reason, the fuel transition will not be proper, causing problems igniting the furnace.

First, check the gas valves to see if the line is clear. If it’s jammed, then open it, clean it with pressure and ensure no water remains. After that, plug it in and press the reset button of your Suburban RV furnace.

Replace Or Clean Air Filter

The air filter of RVs catches dirt and debris very quickly. So when the air filter is not working correctly, there will be a strain on the Suburban RV furnace, which will trip the reset.

You must clean or change the air filter at least once in 3 months. When the furnace is not working, check the air filter and take the necessary steps to clean it, then reset it.

Change Or Wipe Rust From Flame Sensor

Suburban RV furnace’s flame sensor is made of metal, and metals get rust and dirt coat, creating an issue with ignition. So, when the ignition fails, again and again, the reset button trips.

Check the flame sensor plate to see if it has any rust or dirt coat. Wipe them if possible or if it’s damaged, then install a new one and press the reset button.

Clean Air Vents For Better Airflow

Airflow is crucial to prevent the furnace from getting overheated. Ensure all the vents are clear before clicking the reset button, so it doesn’t trip again.
