Dryer has no heat
I have one of those Kenmore "Laundry Center" stacked washer/dryer units. It comes built that way - it is not two units stacked on top of one another (if there is such a thing).
My guess is that it is at least 13-14 years old now (it came with the house I bought) and about 3-4 years ago, it also stopped heating. The dryer would run for a couple of hours and all of the clothes would still be damp and the air in the dryer was not warm or hot.
I searched online and found that the usual cause is the heating element wire was probably burned out if the dryer was otherwise running all right. I found some repair instructions online and the procedures to take the dryer apart (can't recall where - just Google it).
The heating element is like a long coiled resistance wire, similar to what you would see in a toaster but heavier duty. It is strung in a circle behind the dryer drum tub to heat the air that enters the dryer.
If you've ever looked into a toaster when toasting, you'll notice that that thin resistance wire glows red hot which generates the heat. Now imagine that thin wire being red hot and the dryer tumbling, causing constant vibration. It's amazing that the heater resistance wire doesn't break more often!
A pretty handy DIY-er can take the dryer apart and replace the heater wire, but the challenge is getting the stacked unit out in the open somewhere where you can work on it. You need a fair bit of room.
My advice would be to also buy the drum belt replacement kit to also replace that at the same time. If you're going to go to the trouble of taking the dryer apart to replace the heater wire, you might as well replace the drive belt and associated felt pad, etc. at the same time. You DON'T want to have to take the dryer apart again a little later to change that part when it breaks. (It's like a timing belt on your car - if you're doing major work on your car and have the engine apart and it's "about time" to replace the timing belt per the manufacturer's maintenance schedule, might as well do it a the same time to save on repeating the labor again.)
