Furnace Pilot Light Electronic Ignition

This is typically the problem if you can hear your furnace click on but it does not fire up.

Furnace pilot light electronic ignition.

The pilot in turn lights the gas for the burners. Hot surface igniters and intermittent pilots. Like a conventional pilot light an intermittent pilot light still uses a small gas powered flame to ignite the furnace s burners. An electronic ignition lights uses electricity to heat itself up instead of using a gas powered flame.

A faulty or dirty ignition or sensor is a relatively easy fix so follow these steps and you may be able to solve the problem yourself. Intermittent pilots still use a pilot light however it isn t a standing pilot light that remains on all the time to ignite the burner whenever the gas turns on. The electronic ignition system in a gas furnace is a modern development that provides more reliable performance than a standing pilot and offers energy savings through better furnace efficiency. The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite.

One type of electronic ignition is an intermittent pilot. As a result an electronic ignition cannot blow out and it is also more efficient because it doesn t require a gas supply at all times like a traditional pilot light does. There are two different kind of electronic ignition systems. The electronic ignition is only turned on when the furnace is ready to begin a heating cycle and it eliminates the need for a constant fuel supply that a conventional pilot light requires.

The first is called an electric spark igniter which activates the pilot light only at times when it s needed. There are two basic types of electronic ignition systems. The furnace s electronic control board activates an electric igniter that uses a high voltage spark to light the pilot. When the furnace turns on a valve opens up and allows the gas to flow to the pilot light.

Electronic ignition systems there are two basic types of electronic igniters in modern furnaces. The electronic ignition gas ignition systems utilize energy only when needed. This system uses a pilot flame but the pilot lights only when there s a call for heat from the thermostat.
