Atwoods are good furnaces. Our front was replaced in 07, works fine. The rear was "overhauled" in 01 and we had nothing but problems with it, tried a fresh card, worked, then did not. With no paperwork on the "overhaul", I suspected someone had replaced just the motor, and it worked, for a while. Even "Mr. Cheapskate" (me) had to cop to it : fresh furnace. Works perfect. When I looked at the old furnace interior, it was shot! Had done it's job and, "bye bye". I kept the card and threw the rest away. ^.^d
