By Control Thermastat are you speaking of the high limit thermastat located on the tube the flame shoots into?

High limits do not control the heat; they job is to open the heater circuit if the temp gets too high; exceeds 250f. A smaller limit mounted on the heater cage is set to pop at 300f. The drum temp (160f for cotton) is controlled by a Klixon mounted on the blower housing set to open at 160 for high. To get this klixon to shut down faster for perma-press and knits they add a small heater to the bi-metal which warms the klixon up and makes it shut down faster. Hence 4 wires 2 fat wires that carry heat load and 2 smaller wires from the timer.

  You changed the gas valve but did you install new solenoids?

JW Webster - AS near as I can find, there is a thermostat on the heater tube and one on the blower housing. No others. The one on the blower housing has only two wires connected to it (as does the one on the heater tube). It is listed on repair clinic as the cycling thermostat. I will try changing that one.

As for replacing the solonoids, I did not as there were new ones on the valve assembly.

Does your gas valve have a 3 wire quick connect or 2? If it has a 3 wire set up try carefully disconnecting the orange wire from the timer to the gas assembly and see if the gas stays on.
 If it does then you have a bad timer. The 3 wire t-stat on the blower housing is your control/cycling thermostat. These are pretty healthy thermostats but you never know.

First, let me thank everyone for all the advise. It has been tremendously helpful.

I discovered a problem that prevents me from identifying what fixed the dryer. I read somewhere that a possible reason for improper heating is a bad felt. I went to check my felt when I realized that it wouldn't matter since I had grown tired of removing and replaciing the face panel and had been checking each "solution" with the front panel off. That in it's self would prevent proper air flow. I replaced the front panel and, suprise, it is working. Now I don't know which solution was the solution. At least I learned something.  :D
