Thanks "HK", my furnace is located next to my laundry. I cleaned the sensor with a dollar bill as you suggested and removed the existing dust.The burner remained on as designed. My home will now feel like summer during the coming winter here in Michigan. Thanks Again!!!!

At first I checked my air filter. I didn't think I changed it that long ago, but it was filthy. I was hoping that it was that easy. After changing the filter, the problem still existed. I took the probe out and wiped it off with a paper towel real well and it works!!! Saved me $89 for a service call and probably another $100 for parts and labor! Thanks!
