Thanks for the feedback.
Yes, D1 was backwards.
Looking at my popcorn maker, you are correct. It already has a subber
attached to the fan motor. Updated my diagram to reflect that. (I think
I have the diodes the correct way in the diagram, they may be backwards)
Ah, if the diodes you added are what are currently in the popper, then
they make sense for the popper but not your circuit.
They aren't snubbing in that configuration. They're forming a full
bridge rectifier to turn the AC from the wall into DC for the motor.
In your circuit, the incoming power is already DC, so a bridge rectifier
is unnecessary.
