it is taking it over 1hr and 30 minutes just to dry a medium size load of cottons. Doesn't seem way too long?


Yes.
45-55 minutes for an overage load, 60 minutes for a heavy load.

As for your statement that 135-150F is a normal temp range at exit, I guess that surprised me.


To get a better idea what may be happening when, that is why we take and record temp readings ( heat on and heat off ) with the vent attached and with the vent removed to try and get a better idea what is happening during the cycle.
