626611R is an official OEM Blower Limit Switch for Nordyne HVAC equipment. That covers Westinghouse, Miller, Intertherm, Tappan and all other brands that would require blower limit switch to keep blower from overheating Opens at 130 degree Fahrenheit and closes at 110 degrees Fahrenheit. I am showing two of the same controls and offering both for the $15. Yes they are used but coming off a 5 year old Nordyne I have been doing HVAC for more than60 years and I know junk from the good stuff and this isn't someone else's problem that you're getting I personally have clean and tested the limits
