Whitfield wp2 - blower room fan stops spinning

[Minihoser]

Hi, noticed room blower fan on Whitfield wp2 advantage would vibrate and stop spinning. Removed lubed and reinstalled and issue continued. Noticed it spins fine on low. When I turn up half way it spins fine. Turn up to high it will spin up to high, then when auger turns, blower fan will vibrate and spin to stop and restart.

Replaced blower and new one has exact same issue. Runs fine up to 3, when turn to 5, it will speed up until auger turns, and then stop and restart. if I shut off auger to shut down, it seems to spin fine.

Thinking possible voltage power problem, seems when it draws power to auger room blower fan speed changes and forces it to stop and restart.

Controls are black dials.

Any thoughts.

Think I would check wiring sounds like a ground problem to me

Or an issue with the control board

Wiring diagram on page 34: http://www.pelletking.com/pellet-stove-manuals/whitfield-advantage-iit-pellet-stove-manual.pdf
Looks to be a connection on the power to auger and convection blower in the wiring. May just be a loose connection but would be concerned it is the board control not regulating power appropriately.

If the wiring checks out, there are board repair services for the Whitfields ...

Thanks for help, little more info...i can hear the blower fan surge or increase and decrease in speed as the auger turns...if fan goes to full power, auger will always disrute it and fan will rattle slow to stop and restart.

Checked wiring and had 2 fried wires leading to and from the pressure sensor....3 inches at end connected ti pressure sensor from power strip and end connector from auger to pressure sensor was fried....replaved both wires and cleaned and still have same issue...could this have jacked up control board or could faulty pressure sensor cause this...just adding some more info.

Model 67957...so no csr.
Thanks

Pressure switch is designed to cut power to blower if it no longer senses appropriate pressure. Never heard of scorched wires to and from pressure switch... would suspect a short so replacement is appropriate. If blower problems persist, snap disc function should also be verified. They fail on a more regular basis. Then look to the board...

I think bio is right(from my experience)As the blower changes when the auger kicks in,is a control board/controller problem.Also we do not understand disrute and replaved.Really sounds like a failed part caused damage to the control board.

Just guessing: disrute=disrupt; replaved=replaced Does make things hard to read sometimes but those phones can be tough to type on
