Turned off the circuit breaker for the oven and when turned back on, the display/touchpad panel was dead (no lights on). Was working prior to cycling power. Checked power at oven terminals and found OK (240/120). Checked the control transformer primary and found to be dead. Found what appears to be a fuse on the rear of the control board (left of center at top) that is open. Reads open with ohm meter and reads 0 volts on left side with power on. Thermal fuse to control board checks Ok with ohm meter. My questions are:
Is this really a fuse (I couldn’t see it too good and didn’t have a magnifying glass) and can it be replaced.
Is there possibily something else bad in the control board that blew the fuse or some other component in the oven.
Would cycling the power to the oven have blown the fuse.

Yes: it looks like a slow blow fuse to me, should just pry up out of the holders. Sorry could not find the rating for it. Should be imprinted on the metal ends. If replacing make sure you get slow blow type.

It is always a possibility.

Not sure what you mean by cycling. But if you were flipping the breaker off/on it may have taken the fuse out. This is just a guess because I do not have a schematic of the board.
Should I replace the control board
I would try replacing the fuse first.
Should I call the repairman
Cannot make a call on this depends on how electrically/mechanically inclined you are, what the cost is going to be, do you know of a repair shop with good techs etc etc etc
