Electronic Ignition Furnace Won T Light

Since there are many different types of gas furnaces it is difficult to cover every single possible gas furnace problem that can occur with a gas furnace in one article.

Electronic ignition furnace won t light.

The standing pilot light was the regular way to ignite gas powered furnaces for almost as long as these heating systems have existed. Never attempt to light a furnace by a flame manually especially if the furnace has an electronic igniter. One type of electronic ignition is an intermittent pilot. To determine this turn off the thermostat.

But now an electric ignition system have started to replace pilot lights. Please click here to see our furnace control boards page. The hsi heats up to around 1 800 f to 2 500 f and glows red hot. The most common reason for this problem is because the pilot light is not on.

Unlike older pilot lights which have to be lighted by hand automatic pilot lights now commonly found in most home furnaces are regulated by a thermostat and only ignite when needed. When your furnace fails to ignite the first place to look is the pilot light. Because an electric ignition does not need constant power the way a pilot light does it contributes to energy savings. The pilot light or ignition sensor is usually the most common issue when your furnace will not ignite.

The furnace s control board might not be supplying the voltage to the ignitor.

If you have a newer furnace or one with an afue rating above 80 it most likely has an electronic ignition system.

This system uses a pilot flame but the flame lights only when there s a call for heat from the thermostat. If your furnace is an electronic model with an automatic ignition for the pilot light but it won t light there may be an issue with the ignition. When the thermostat calls for heat 24 volts are sent to the electronic ignition control module which energizes the furnace blower and other systems and sends 120 volts to the hsi.
