Whitfield Blower Fan slows with auger

[Oregon Josh]

I just replaced my auger motor, end plate, and removed the CSR in my Whitfield Adantage II-T. I'm impressed with the new motor, but I'm still having one problem (that was happening previous to the repair).

Sometimes (no pattern obvious) when the auger runs, the blower fan slows and rattles. I've cleaned and oiled the fan, and it turns freely. There is a little end play, but not much. I've bypassed the control board and am running the fan straight to an outlet, and no problem. It seems to me that the auger is drawing enough current to slow the fan.

Is this a control board issue? If so, sounds like it's time for a gas insert.

Any other thoughts on this issue?

Thanks!

IF your whitfield has the older style serial bus for connections you may want to remove it, clean it as well as clean all of the wire disconnects. Each are on their own circuit but the may share a common which has a poor connection

It does have the old style bus, and it's not exactly new and shiny anymore. I'll give it all a good clean and see if that helps.
Thanks!

It sounds like you have a high resistance some where in the power wiring. Probably a tarnished quick connect. The resistance causes a Voltage drop when current is drawn. When the auger is working the Voltage drops and the blower motor is starved for power.
