Armstrong ultra sx 90 furnaces will not ignite.
Recently, I ran into a situation where my white ultra sx 90 furnace was not igniting. I tried everything possible to start the unit, but nothing happened – even the pilot light wasn’t lit.
I looked up the error code online and found that most were related to some gas leak or ignition problem. After further investigation, I discovered that my furnace’s burner was broken and needed to be replaced. This was very frustrating as my unit was less than two years old and needed replacement components.
Thankfully, after contacting Armstrong, they sent me an email with a link to a form that would allow me to order new parts for my unit for free!
When you turn on the armstrong ultra sx 90 furnaces and the flame goes out, there is no need to worry. This furnace will not light up unless it senses proper airflow. However, if the air intake is blocked, it may cause a fault code to appear on your service panel.
If this happens, there are a few things you should try first before calling an expert out to troubleshoot:
– Check the power cord for any damage or tears. If there are any tears or damages, replace it with a new power cord immediately
– Check for debris that could be blocking the air intake area of your unit. If there is debris present, try using compressed air from a vacuum cleaner to remove it
– Finally, check to see if anything in your home has been switched off and ask yourself if you were cooking or doing some strenuous activity recently that made lots of smoke and heat build up in your home
