nor do I hear any sound from the timer that normally ticks until the time has ended.[/COLOR]
I am assuming this is in timed dry mode.

Just looking at the breaker is no good, see below.

Since the problem is probably power or the door switch or the timer I would start with the power. It is the easiest to check.

Try flipping the breaker off/on slowly a couple times. Sometimes you can loose half the line without actually tripping the breaker.
Check the voltage at the plug
L1 to L2 should be 240 volts
L1 to Neutral and L2 to Neutral, both should be 120 volts.
If OK
Unplug the unit and check the wires at the terminal strip in the machine to make sure none are loose or burned out
If OK
Check the power at the terminal strip.
Do this with the heater off and on.

[COLOR="Blue"]Would a faulty door switch cause the timer not to tick when it is set to a time?[/COLOR]
Yes it will.

Following is the circuit for the timer when in a timed dry setting.

Neutral , Door Switch , Timer Switch 4 (T to WB) , Timer Motor , timer contacts BU to BK (blue to black) , L1 line voltage (120 volts)
