Whirlpool Drying not turning

It’s a 5 yrs unit, stop turning while hot air still blowing.
It stay silent while hot air is blowing. Definitely not drying my wet cloths.

I opened up the unit and found the schematic and thermal fuse, but I don’t know how to check whether it’s the motor is bad or just the thermal fuse.

Any tips would be appreciated.

thanks,
