Kenmore gas oven 278.3128890 ; old (Goldstar) ERC had failed (buzzing relay; unable-to-control rotary switch).

Replaced with Robertshaw ERC unit (GE replacement part WB27K5053), which came with replacement temp sensor. New unit's clock functions work, but "bake" and "broil" buttons do nothing when pressed except blink the time display. Temp sensor measures just under 3K ohm @ room temp.

Suggestions on how to diagnose? debug?

Check your wiring.  Then check it again.  These kits can be tricky to install, you have to follow the directions exactly.

Checked, and checked, and checked again.

White - N; Black - L; Green - Ground
and Orange - BA.

Instructions also say to jumper BA with BR.
I've tried it both with and w/o the jumper.

If you're sure you did it correctly, that only leaves a bad ERC. But, I gotta tellya, pilgrim: of all the electronic boards I've replaced, I honestly can't remember the last one I got that was bad off the shelf. Oh, I've had several that made the *think* they were bad, but it turns out they were just messin' with me. They, too, tasted my blade.

Yes, I know; I'm _very_ loath to believe the board is bum. Any way to check it though?

One thought is that the connection (ribbon cable, surface mount) between the keypad and the control board is faulty - but would that cause the no-action Bake/Broil? ... domo ..

No check, cash only. :P

Your only option at this point is to swap out the board with another new one.

it takes a (^^%$#$#@%^U) to understand  the G.E . wiring info . but i can help you did nothing wrong you just have a different replacement board  the wb27k5053 has been changed (ge has changed many of its part no3 )there is a jumper that needs to be used . in your case you need to relocate 1 of the terminals on the sensor

Yes! JahJahBinks is correct -- the replacement cable for the sensor is a 2-wire cable, with a 3-pin connector to the board. As supplied by the manufacturer, the cable is incorrectly wired. The fix is to move the wire from the center pin on the cable to the outside pin. (the cable connects to pins 1 and 2, but should connect to pins 1 and 3).
