Hello Cliff Hendershot,
One USA manual ... said turn off power for 10 minutes
(sounds reasonable after
looking up cost
of control board)...
websites are not responding to your number.
Closest I could get was to a $78 (us dollar) control panel
>> ((IMPORTANT PART
... has a video that shows repair))
I could NOT get a good READ on your JBP24... page 8
So I attached a JBP19 (below)... Page 12.
The most COMMON reason to FAIL after a cleaning
is your OVEN CONTROL is "off normal"
(You still do not have your MANUAL MODE restored).
Normal = "AUTOMATIC"
LIGHT Off (NOT LIT)
Check your "oven controls"
Oven elements do break during routine use...
Check both roast & bake elements for continuity.
