Beckett AFG w/ R4184D 1027 and Side Shot SS1 Power vent not firing up

Good evening, and Merry Christmas! Santa must be mad, because I awoke to a lifeless heating system this morning. I have a Beckett AFG burner with a Honeywell R4184D 1027 controller firing a New Yorker boiler. The system is power vented (SideShot SS1). When I looked at it this morning, the reset button on the controller had popped, so I pushed it, but nothing happened. Neither the power vent, nor the burner, came back on. I switched everything off with the emergency shutoff switch on the basement stairs, waited a while, then tried again. Again, neither the power vent nor the burner made a sound. In the past, I have had issues with filters clogging, and have had to blow out the line to the tank, replace filters, bleed, etc. In those instances, the burner always *tried* to fire up but couldn't due to lack of fuel. The power vent also always turned on whenever I reset the controller under those conditions. The difference now is that neither the power vent fan, nor the burner, appear to be doing anything. According to the documentation on the SS1, it appears that the burner shouldn't get any power until the power vent is on, and the fan proofing switch has closed, so I'm confused about why the burner gets enough juice to pop the reset button. The SS1 has power on L1 and L2 but not on the orange and red terminals of the terminal strip, which according to the documentation indicates that "sideshot and the appliance are not interlocked correctly, or malfunction of appliance controls". I lifted the transformer on the burner and was able to turn the squirrel cage on the blower with no problem, and after a reset, the transformer appeared to be getting 115V (as tested with leads on the solder on the board).
