Only a little heat is going to the cylinder (by 2 users)

Zuraxus what you are seeing is normal for a time. Here is how this dryer works. With a wet towel in the dryer, the first 5 minutes is testing to see if the load is wet. If so then between 5 & 10 minutes the dryer will turn on the 800 watt heater section (only in clockwise rotation). If still wet enough from 10 minutes to 15 minutes it will turn on the 1900 watt heater (heating only in clockwise). If still wet enough 15 to dry will turn on the full 2700 watts in clockwise and 800 watts in counter clock wise. That is how the cycle works. However it is hard to tell with the rear cover removed as the blower pushes the air thru the heater. Careful that by running with the back panel off you don't trip the high temp manual reset protector. So yes this sounds normal. What is the issue that is causing you to think the dryer isn't working proper?
