Repairs a Gas Furnace May Need
As a homeowner, it’s never advisable to repair your own furnace, but it is good to be aware of certain kinds of problems that can develop with your heating system. Why?
Understanding what your technician tells you about a particular heating repair in Beavercreek, OH, allows you to have a better grasp on what the problem is as well as the scope of the work to be done on your system. Here are some examples of problems that can develop with your gas furnace:
Issues with the Limit Switch
The limit switch is a mechanism that functions as both a component of your blower assembly and as a safety device. As part of the blower assembly, the limit switch makes sure that the blower doesn’t turn on until the warm air has reached the correct temperature; this ensures that cool or tepid air doesn’t blow into your home. The limit switch also makes sure the heat exchanger doesn’t get too hot; if the limit switch senses that the heat exchanger’s temperature has exceeded a pre-set safe temperature, it turns off the burner immediately, extinguishing all combustion.
There are 3 types of pilot lights, and 2 of them are electronic: standing pilot, intermittent pilot (electronic) and hot surface ignition (electronic). Problems can develop with all 3 types of pilot lights, which will create problems with your furnace’s ignition. Sometimes the pilot flame may not read as viable and the system will not open the main gas valve. The pilot nozzle may be dirty, which makes it difficult for the gas to stream for the pilot to light. There are multiple reasons your furnace may not be igniting, so it’s important to allow a trained expert to determine and repair the problem.
Cracked Heat Exchanger
Heat exchangers are components made of medium-sized, serpentine tubing that sit at the heart of your furnace. Heat exchangers are open at both ends; when the burner lights and heats the heat exchanger, the toxic byproducts of combustion enter the bottom end of the open tubing and flow to the top, where they are vented to the outside via your chimney or flue. The heat from the outside of the heat exchanger is blown into your home. If the heat exchanger develops a crack/s, these toxic byproducts, including carbon monoxide, can enter your living spaces.
