Harman pellet stove blower not coming on. All lights are on and not blinking.

There are a few possible causes for this issue with your pellet stove. One possibility is that there is an issue with the auger feeding the pellets into the burn pot. The auger could be clogged, or the timing of the auger may need to be adjusted. Another possibility is that there is an issue with the airflow in the stove, which is preventing the fire from maintaining a consistent flame. The air intake or exhaust vents could be blocked, or the blower fan could be malfunctioning. Additionally, the control board of the stove could be malfunctioning, causing the auger and blower to cycle on and off erratically. It may be best to consult with a professional technician to diagnose and fix the issue with your pellet stove.

Test the feed motor with a jumper and wire power to it directly, if that fails to make it run you have a defective motor.

I would suspect the auger motor is defective, remove it and test the motor.

If you are just running the blowers and what not, then yes you can. Blower motors do not take more than between 200 and 500 watts or so, so you should be okay running the blowers.

You can do some troubleshooting by looking at the glass fuse after it has failed. If the element looks melted and there is no other discoloration, then the fuse probably blew as a result of an overload somewhere. If the fuse is burned black, then it's probably a short in the system.

You can meter the motors to see if they are shorted anywhere or open.

It sounds like you may be correct about the circuit board.
