Since the beginning of gas operated refrigerators, manufacturers have tried to come up with convenient ways for the user to light the burner.

Some of the earlier refrigerators used a wick (a cloth soaked in kerosene) on a long rod to ignite the burner. Over the years, various ignition devices were developed and implemented by the manufacturers. These are listed below:

DSI Board (or Gas Control Module)
Electronic Igniter
Flint Wheel
Glow Coil
Piezo Igniter
Zip Tube
