Cleaning a Dirty Flame Sensor Rod in a Direct Fired Heater

When using heating equipment, there are definitely common problems that you can run across. This article will help want you through the process of solving a common problem with direct fired heaters, which is a dirty flame sensor rod. First, let’s go over what a flame sensor rod is. 

Cleaning a Dirty Flame Sensor Rod in a Direct Fired Heater

A flame sensor rod will tell the heater that the main gas burners have ignited. If this sensor doesn’t detect a flame after a certain amount of time, it will close the gas valves turning off the fuel source. If your flame sensor rod is dirty, then the heater won’t keep your heater lit.

This takes us to a real life example of what may be happening to your direct fired heater. If you’re turning your heater on and the flame lights, but then quickly goes out, chances could be that flame sensor rod is dirty. The good news is, it is an easy fix. To resolve your problem your will only need:

 A.) Your direct fired heater B.) A piece of emery cloth or sand paper.

Instructions

  1. Problems with Your Heater

    So you’ve tried to start your heater and the flame lights, but then quickly shuts off. The first thing that you will want to do is attempt to start your heater again. It could be that you just had a bad start.  If the problem persists, continue to the following steps.

  2. Cool Your Heater Down

    Before moving onto the next step, we’re going to turn off the heater. Unplug the electrical cord, then turn off the gas valve.  Next, let your heater cool completely before attempting to clean your dirty flame sensor. Remember that there was just a flame lit in the heater, even if it wasn’t for very long, the system could still be very hot.
