The Symptoms of a Failed Glow Plug Controller

A modern diesel engine has a single glow plug controller that manages all the glow plugs. Sometimes you might not find one bad plug, so there are some symptoms to notice.

  • Glow plug light: The glow plug light on the dashboard flashes or stays on.
  • Hard to start: The engine starts slowly in warm weather or does not start at all on cold days. However, this is sometimes because of the fuel system or the battery.
  • White exhaust smoke: When starting, a lot of white smoke may come out because the diesel is not burning fully.
  • Poor engine power: If a glow plug fails, the fuel will not burn fully, leading to a loss of power and less efficient operation.

Choose the Right Glow Plug Controller

Glow plug controllers are not universal parts. Each controller is designed for a specific engine model, voltage system (12V or 24V), and even fuel type. Installing the wrong controller can cause it to overheat and become damaged. Therefore, you can put your machine's model and part number in the search bar to find an exact matching controller.
