Drum turns but no heat .

Is there a sequence for troubleshooting the circuit?

Can it be checked from behind the control panel by selecting particular switch settings to determine if the heating element is good/bad or the thermostats are good/bad?

What other elements may be involved with the lack of heat?

Does the drum light work?
Does the timer advance in Timed Dry mode?
Does the timer advance in Auto mode?

Can it be checked from behind the control panel by selecting particular switch settings to determine if the heating element is good/bad or the thermostats are good/bad?
If timer advances in Auto mode then odds are high that the heating element is good as the timer gets power through the element in this mode

What other elements may be involved with the lack of heat?
Here is your circuit path for the heating element when motor is running:
L2 , M2/M1 motor's centrifugal switch , HEATER , HIGH LIMIT THERMOSTAT , CONTROL THERMOSTAT , A/B timer contacts , L1
