Does anyone happen to have a wiring diagram for a Samsung DV48H7400EW/A2 dryer?
The dryer turns on and runs, but no heat is being generated by the coil. I've replaced the common offenders: heating coil, fuses, thermostat and thermistor. I checked the outer pins on the centrifugal switch and it seemed to activate fine when the plate is pushed back. A multimeter confirmed that there's a connection on those outer pins when the plate is back. I also confirmed that the plate rotates back when the dryer is turned on. So, I replaced the control board assuming it was something with the heating relay, but the issue persists.
I was reading through some of the other forum posts and found that there's another pair of pins that may need to be checked on the centrifugal switch, but I don't have a wiring diagram for the dryer to know exactly what to check.

If anyone could share that diagram I'd really appreciate it. I'd also love any additional recommendations on troubleshooting steps.
Edit:
I forgot to mention that I used a spare piece of electrical cable to jump the wires that connect to the heating relay and the coil heated up fine.

FIXED - DV45H7000EW/A2 Samsung dryer not heating
dryer runs but no heat. took dryer apart, element is good - 11 ohms, new thermistor, high limit fuse is good, therm sernsor is good, wiring is good, motor contacts work, BUT NO HEAT. relay on PCB never makes contact. have 3 control boards and none of them work - relay never makes contact to...
