All Nordyne air conditioners come with printed or online user manuals for troubleshooting common issues. Nordyne, which as of January 2015 is known as Nortek Global HVAC, owns the Broan, Frigidaire, Maytag, NuTone, Tappan and Westinghouse brands.
Nortek Global HVAC offers step-by-step online troubleshooting guides for each brand of air conditioning unit it makes. These troubleshooting guides, in addition to the user manuals included with each unit, can save money and time when investigating an issue. Instead of immediately resorting to an electrician or HVAC specialist, these guides take the user through multiple issues that are fixable without assistance from a professional.
