100684-09 Lennox Armstrong Ducane Gas Furnace Pressure Switch

My heater was not working properly and I was troubleshooting the issue. After many attempts and failures I decided to just replace the pressure switch. Upon looking and searching online some were close
But had a different color dot sticker in back. I almost wasted money at another store when I called NWF. The guy was clear about what the difference was and would have caused me more problems down the road. I ordered it on Saturday and expected over a week to arrive , not the case! I got it within days before the end of the week and it’s snowing !

Thank you NWF for your optimal service response and look forward to recommending your business products as my option to buy online.
