I have a Maytag gas range Model # MGR5875QDS and after every power outage in
my area the display on the control panel is blank. It does not matter which
button your press on the control panel nothing works but the igniters for the
range top burners work so there is power to the range. After about 4 to 5
hours the display starts to work and the range is fully functional again. Is
there a thermal fuse that needs to be reset or is faulty or is the control
panel faulty and needs to be replaced? Thank you in advance for any input.

IDK, that's a very weird one. Only thing I can think of is that it has
some defect in the reset circuit on the control board. They might have
some RC circuit that holds the chip in reset for a period of time after
power first comes up. You don't want digital logic to start running
when power has only come up to 50%, 70%, etc. So you hold it off from
starting with a reset circuit for
some number of milliseconds. If they are using a capacitor, it's
possible it's aged and failing, but still you'd think it would charge up
in a few seconds, not hours.

But I can tell you this, unless you want to spend a lot of $$$ for a
new control board, and/or your power goes out frequently, might as
well just put up with. From what I've heard, it sounds like maybe
the oven wouldn't be usable for a few hours, but otherwise the burners
work. You can find the cost of a new control board online. If you
can DIY, that would hold down the cost. Note I'm assuming it's the
control board, it's logical that's where the problem is, but without
seeing a schematic and/or testing, that's just the likely culprit.
