The H400FDN heat sensor sparked while reassembling (fixed a manafold leak). As a result, the control panel went blank.
It appears a surge blew the purple 3A fuse on the main panel. Fortunately, there was a spare fuse in a little baggie on the left side that also contained a wiring diagram. I replaced the fuse and the heater fired up. SUCCESS
Lessons learned: Disconnect power before unscrewing heater. Check fuses if the control panel is blank.
