I have a gas Whirlpool Ultimate Care II dryer. I doesn't dry the clothes completely with a normal size load on timed dry on High for 60 minutes.
Maintenance:
- Cleaned trap
- Vacuumed internal vent
- Replaced Vent hose (moderately dirty)
- Repalced louvered vent cap (slightly stiff)
Exhaust temperatures:
- Measured at dryer exhaust
- All covers on
- Timed Dry
- No clothes
- High (Heavy) 175 degrees to 125 back to 175 in 1:40
- Medium (Perm Press) 172 degrees to 123 back to 172 in 1:40
- Low (Knit) 165 degrees to 114 to 165 in 1:40
- Removed rear panel. Nothing interesting to report.
Any ideas?

Actually sounds like you are getting too much heat.
To clean it out thoroughly you have to remove the lint chute, which can be done by removing the two screws under the cover on the top, then taking off the back and taking out the four screws that hold the lint chute on.
Check the blower while you are looking at things.

Sidfink,
I thought you had it. I cleaned the chute which was pretty dirty. I vacuumed the blower though it wasn't too bad. Temperatures went down about 5 degrees everywhere and the volume of air was considerably increased so I was pleased. Attached the vent and tested with an "average" load on High for 50 Timed minutes. It was drier but not dry. It used to dry in that amount of time.
Now I'm wondering if the length of time to go from 170 to 120 to 170 of 1:40 is too short. So it's not staying hot long enough. I don't know how to know that or test for it. I assume it is the thermostat that would control that, correct?
Thanks for the input.

It is still running too hot, and if the air passages are clear then I would replace the operating thermostat, this part here. Part number: AP3045874
50 minutes is not necessarily the correct drying time, depending upon the size of the load and how wet it is going in. Anyway, replace the thermostat and see what happens.

SidFink,
I replaced the thermostat. Pretty easy job. Everything seems to be acting the same. Temperature ranges and duration are identical. A load of towels that seemed well spun from the washer took 2 cycles of 50 minutes on High to dry completely.
Of course, I'd rather not buy a new dryer but I'm at a loss as to what else to investigate. Does the duration of the heating cycle of 1:40 from low to high to low seem long enough?
Thanks for the help.

Your cycles seem fine, and the temperature is certainly high enough to do effective drying.
It should not take 100 minutes to dry a medium load of towels if the air flow ok. Is your lint filter ok, sometimes they get clogged and you cannot see it unless you look very closely.
If you have a good strong hot airflow I cannot say why the drying is taking as long as it does. A dryer is a fairly simple device, it tumbles clothes in a drum where hot air is being blown through. The hot air absorbs the moisture and carries it out through the vent. All you need is hot air, tumbling and strong air flow, so if you have those you should have good drying.

I agree that they are relatively simple devices. I'm not sure what to try. Are there simple measuring devices to test the moisture after the washer and/or CFM out the back of the dryer?
My fear is that I'll buy a new dryer and end up in the same position.
Thanks for all the input. The AAP website is a very easy and efficient site.
