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.
4. Shined flash light down lint trap saw nothing put hand into dryer exhaust
port as far as I could found nothing.
5. Examined heater element through view hole on top appears that all coils
are turning on.
6. Checked continuity SP? across the two heater leads while disconnected
from wiring. checked good.
7. Observed heaters while unit is running. Found the turn on and off. This
is because the cycling thermostat Does that sound right?
8. Found that while heaters are running they draw 22.5 amps per leg.
9. Checked Thermal fuse is good.
10. 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.

Default

and it used to work better ?

did you check/clean the rest of the exhaust vent (to the outside) ?

try it with the vent disconnected.

is there good air-flow out the vent ?

check the air temp out the back of the dryer (with a meat thermometer) with the dryer empty
(wet clothes will take a long time for the dryer to heat to the limits)

it should be about 150F
