Dryer was working, but no heat.
First I unplugged the dryer, then removed the back panel, this exposed most all of the wiring and I could see the heater coils.
Not knowing what the problem was I started looking at the coils and could not see any broken parts.
So then checked the thermal fuse for continuity I removed the two wires from it with a small pair of needle nose pliers, it was held in place by two screws, once they were removed the fuse came out easily, I checked continuity with a volt meter placing the meter on X1 Ohms and could not get a reading.
I replaced with a new one and put it all back together the way I took it apart.
Then I plugged it in and it worked first time, I now have warm dry clothes.

No heat but would run otherwise
Cleaning the lint out of the whole machine took quite a bit of time--it was everywhere. Underneath the lint trap was a collection that ultimately ruined the thermal fuse where it restricted the air flow considerably.

Ascertaining the problem was the most time consuming part.

The actual repair was quite simple and didn't take but 15-20 minutes.

No Heat. Dryer keeps running but no heat to dry clothes.
Repair was very easy. We are in the internet age so I use it all the time to get info on how to repair any thing in the house including cars. This time it was my dryer. I typed up 'Kitchen Aid dryer has not heat'and pressed searched and PartSelect came up. Typed in the model number and looked up the comments on No Heat. They had pretty cool site that shows videos on how to repair this things too. Came to conlclusion that the THERMAL FUSE was the main problem. Ordered it and as well as the Igniter assy just to make sure and as well as save on the shipping just in case. Ordered on Sunday night and the shipped the next day. It arrived on Tuesday. Unfortunately had a little problem on the shipment. Called PartSelect and they are so awesome they shipped me new parts asap at no extra charge. Awesome Awesome! Parts came in Thursday and first installed the Thermal Fuse and BAAAM! problem solved. Did not need the igniter assembly. Now I have an extra part in storage.
To replace the Thermal fuse.
1. Disconnect Dryer from power outlet. Remove the bolts on the back panel with a 1/4" socket. I used power drill because it is much faster.
2. Locate the Thermal Fuse. Disconnect wires and remove the bolt. Slide it up and pull. Install the new one and reconnect the wires. Replace the panel and plug the dryer.

That solved my problem. It should solve yours too. The whole process was less than five minutes.
