heating problem

Where to start?

Dryer seems to take a very long time to dry clothes if at all.

What I have done.

  1. Cleaned vent duct and made sure that exhaust hose was free of kinks.
  2. Run dryer disconnected from exhaust duct (just in case)
  3. Measured power at wall socket 220VAC between both lines 120VAC
    each line to Ground.
    [LEFT]4. Shined flash light down lint trap saw nothing put hand into dryer exhaust
    port as far as I could found nothing.
  4. Examined heater element through view hole on top appears that all coils
    are turning on.
  5. Checked continuity SP? across the two heater leads while disconnected
    from wiring. checked good.
  6. Observed heaters while unit is running. Found the turn on and off. This
    is because the cycling thermostat Does that sound right?
  7. Found that while heaters are running they draw 22.5 amps per leg.
  8. Checked Thermal fuse is good.
  9. I checked another switch/Thermostat I think it was high limit. good
    continuity.

I hope this description will help you have a good picture of my problem and thanks for all the help.
