I recently had my furnace thermostat **** out. Never had to mess with one before and I was dreading it. Finally just bit the bullet and ordered a replacement from Amazon. $16. Took me 10 minutes and half of that was trying to get the screws and wall anchors out of the little ziploc bag. Now I can adjust the furnace to less than 76 degrees. I was dreading it because it seems lately that everything I try to do I have problems with, and everything takes twice the time and money it should. This went so smooth I had a drink to celebrate. Cheers!
