Have you checked the flame sensor AP6008294? If not, unplug the dryer, disconnect the wires from the flame sensor and check for continuity on the terminals of that sensor, should be closed.

If that’s good you either aren’t getting voltage from the control side or neutral from the motor side.
Since you’ll already have access to the heater area when testing the sensor, I’d go ahead and access the control board and disconnect the wires going to the heater relay, should be black and red wires. Place one lead from your meter in the red wire, go to the valve and disconnect the 3-wire connector, place your other lead in the blue wire that runs back to the hi-limit thermostat, and check for continuity. If that gives you a good continuity reading then the thermal fuse, hi-limit thermostat, thermal cut-off, and wiring between the control and the valve should be good. At that point you are down to the control board or the motor.
