If you want to replace your hot surface ignitor on your water heater, you will need to make sure that you know what you are doing. These handy little devices have become the preferred method of turning on the heat for hot water, replacing the old pilot light system. As with anything, when you come to install one, you have to pay attention to detail.
Get the Right Ignitor
Before you start the replacement, make sure that you get the right kind of ignitor for your system. Different hot surface ignitors work with different machines, and you may find that the wrong model will not work. Check the model number on your machine before you try anything.
Check the Flame Sensor
Included with the hot surface ignitor is a small device known as the flame ignitor. This knows when the flame on the heater has started, and regulates the temperature. However, if it gets dirty, or comes into contact with parts inside the heater, it can react prematurely, turning off your water heater before the process is complete.
Ensure that you are correctly wiring up the hot surface ignitor. Read the instruction manual closely before you begin wiring.
