No display readout. Refrig Tech here

Refrig tech looking for manual.

Maytag M:abb1924dew S:12981302JC Bottom mount freezer.

Fridge part is warm, freezer freezing for now with good frost build-up on back wall BUT there is no display readout on the fridge/freezer control readout. Is there some secret keypad punching to get display back or has the control board & display board crapped out not putting fridge into defrost, which I assuming it does because I can’t find any defrost control device anywhere.

Looking for manual or anyone who knows this unit, would be Great.
