Troubleshooting a Samsung Dryer No Heat problem using the Schematic-- appliance repair training

This is an excerpt from a longer webinar presentation showing an application of using the schematic to troubleshoot. Knowing how to properly use a schematic for your troubleshooting is key to saving money and time. In this short presentation, the Samurai shows performing circuit analysis to identify the most useful, but also the most convenient tests to quickly zero in on the problem. Topics covered include:
- reading schematic diagrams
- strategic selection of your reference voltage
- doing live testing (appliance plugged in and running) vs. Ohms testing
- using a loading meter to test AC line voltages
- troubleshooting from the control board to eliminate unnecessary tear down

If the dryer is constantly tumbling as soon as it's plugged in and before the control board even powers the lights on is there any access to constant power through any places besides the control board? Is there anything that could be wrong with it besides the actual PCB? It constantly tumbles as soon as it's plugged in with no heat. It's possibly not this particular dryer but it is a Samsung dryer so I'm assuming it's probably similar.

Currently have no heat on a samsung electric dryer....relay on main board not closing but getting the digital signal from rx & tx....that means the relay is bad on the main board correct
