Jeff your problem is gonna be in the motor circuit. The motor works on 120 volts.
The components in the motor circuit are:
motor, duct fuse,door switch, timer. If all other things have continuity with their wires removed, then your timer must have a bad contact inside. Very rare. Usually the arcing from the heat circuit but on occasion a burr will occur on a timer contact. It is possible to file the burr down but ya got to be careful. The way I do it is remove the shank on the timer so I won't disturb the innards. I remove the 2 screws and carefully examine the contacts looking for a burr . I file that down and sometimes I can get it to working. If you fail to remove the keeper the barrel will come out and then you will have hell on your hands putting it back together.
