While our customers are wholesalers, Packard knows that you, the contractor, have a choice. You are often presented with many buying options, and being well-informed about your purchase can help make your job easier and more successful.
This is why we have dedicated a section of our site for contractors. In this section, you will find helpful product tips, tools and some clips from our training classes. We’ve also provided a distributor locator so you can find the nearest wholesaler who can give you access to Packard products.
Taking care of a common furnace problem.
What a way to start the day! It’s freezing outside and my bedroom seems as cold as an igloo. The furnace isn’t providing heat. It seems to be operating, but no heat is produced. I don’t seem to have a flame in the furnace. Unless my fuel, in this case gas, is ignited it won’t produce heat. The hot surface igniter could be the culprit.
The igniter is designed to ignite the gas released into the combustion chamber. After the draft inducer, where appropriate, is energized and clears any residual gases from the combustion area and the flu, the igniter is energized. When it becomes “red hot” it ignites the gas released into the combustion chamber, providing heat.
When replacing the igniter always assure that the replacement is the proper voltage. Generally, that will be either 120 or 80 volts A/C.
Handle the igniter with care! Some igniters are silicon carbide which are very fragile and break easily. A slight bump against the furnace cabinet could fracture the device. Also, avoid touching the “rod”. Any oil from the fingers could lead to failure.
Silicon nitride igniters are also available and can be used in place of the silicon carbide. They are much more durable and are not as sensitive to touch.
Stay safe! Only qualified professionals should service gas appliances.
Let’s keep the heat on!
