I am searching for help diagnosing an Admiral Dryer (model EAD4475TQ1) that has a couple of issues. There is no heat at all in any of the heating cycles, but the dryer will run and blow cold air during the HEAT cycles. When attempting to use the "no heat fluff" cycle, nothing happens at all. I have tried pushing the button as well as holding it down, and I get nothing.

The dryer is approximately 3-4 years old. It belonged to my mother, and when it stopped heating a year ago she stuck it in a storage building. When my 1980s model Whirlpool died it's final death last week another family member pulled the Admiral out of storage to see if he could get it to work. He replaced the fuses, thermostat, and heating element with no luck.

I suspect the timer, but I don't want to start ordering parts blindly. Any help diagnosing (and determining if it's actually worth repairing) would be greatly appreciated.

No, it will not start in fluff mode when you push the start button. It will start in all the other modes, just no heat. I noticed today the dial does not "click" when turning it to fluff mode, and I feel resistance that I don't get turning to anything else.
