Problems with Ignition
Newer gas furnace models no longer operate on standing pilot lights. These furnaces are using hot surface ignition or intermittent pilot.

The most common model runs on hot surface ignition system. It looks like a filament found in a light bulb. Once the thermostat sends a signal that the furnace needs to be switched on, the electricity will start running through the igniter for the furnace to heat up. It works like a standard light bulb and when used frequently, its thin piece of metal will start to show signs of wear and tear.
There are other problems that you will encounter with modern gas furnaces. Some of which include switch breakages, malfunctioning parts and even failure of computer boards to operate. For older furnaces that still use a standing pilot light, you will need to replace it with a modern furnace if it is no longer as efficient as it used to.
Blower and Belt Problems
