Do-It-Yourself Story

Disassemble to gain access to thermostats, igniter, and thermistor. Test resistance to determine which component was faulty. Order component(s) from APP. A bit of a hassle, not difficult. The only bothersome parts were cleaning all the lint out of the ductwork and realizing I had routed the drum belt on the wrong side of the tensioner, thus having to tear down and reassemble twice.
