People don’t realize that you can do it yourself if you know how to read. I had the time to do it so I fixed my furnace two times since buying this house. The second time all the little labels fell off and I got two wires wrong on the circuit board. Called my oil supplier and tech came out and figured it out in fifteen minutes. $130.00 service fee. LOL. But if your busy with life you have to pay for the convenience. I gutted my bathroom and tiled it. The works. Not perfect and two years later I need to cut a couple of trim pieces. Use Schluter as underpayment for tile. Awesome product.
