Began to troubleshoot by clearing lent from the system. There was a fair amount and I thought that might solve the problem. It did not. I have checked the continuity on every part related to the heating cycle and they all have continuity. Can these components still be defective even when they show continuity?

See the attachment for the wiring diagram.

What do you mean by "not heating properly"

If it is no heat then I would check the power to the unit first.
If there is no heat and in a timed dry mode the timer does not advance then it is probably a power problem. The heater and timer require the full 240 volts.
Another possibility would be that the centrifugal switch on the motor is not closing when the motor runs.

Yes but not as a no heat condition.[/COLOR]
They can weld the contacts closed and therefore not open when they should and then one of the thermal protects should open.

Did you check the timer contacts?
A to B and A to C should be closed.

I put it all back together after finding out that all parts checked out as functional. I did discover by running the dryer on auto heat the coils were ignited. While on timed heat (the one we use) they did not. I am now assuming this is a timer problem. I dried some clothes on the auto cycle and it worked perfectly. What do you guys think?
