Replacement parts for General Electric NVLR333EV0WW Electric dryer | AppliancePartsPros.com

this unit is a GE so getting tech info is very difficult. They like to keep everything a secret.

Here is a good link with at least some info on these units.

Here are a couple example wiring diagrams that may be useful.

Have you looked inside the control console, often they store a wiring diagram there.

In most cases checking voltage to the Neutral or frame/ground if a 3 wire hook up is confusing when working with a 240 volt heater circuit but in your case it may be helpful.
Most units run the power (L1) through a set of time contacts then through the heating coil and thermostats and then through the motor's centrifugal switch to L2.
So with the dryer off and set mid heating cycle, do you see 120 volts at the thermostats and heating coil with one meter lead on Neutral/ground. If not then odds are that the timer contacts are shot.
