You cannot use the drum light as an indication that the power for the motor is OK on this unit.
The motor uses L1 to Neutral for power.
The drum light uses L2 to Neutral.

First I would check the power.
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.

That the breaker has been tripping in the past is not good.
It could be a breaker problem or a machine problem.

The most likely cause of a machine problem would be a grounded element.
Unplug the unit and both wires from the heating element.
Mesure acrposs the heating element, should be in the 8 to 12 ohm range.
Now measure from each element connector/side to the case. Both should be infinite ohms.
If not the element is grounded and should be replaced.

Now back to the current problem.
If the power is good then unplug the unit and check the two thermal fuses.
One on the heater and one on the blower.
Both should be 0 ohms.

The most common cause for the blower fuse blowing is a dirty/clogged vent system.
The most common cause for the heater fuse blowing is a grounded element.
If blown the hi-limit thermostat may also have to be replaced.
