What an F-code is
Any display of F with a digit or letter behind it falls under one heading in the manual: function error code. Monogram defines none of them separately, so what you do is identical for each.
Manual routine
Tap Dismiss on the LCD.
Wait an hour so the oven cools, then resume cooking.
Should the code return, cut every source of power to the oven for 30 seconds or longer and switch it back on.
A third appearance means calling for service.
Covered ovens
Monogram lists this entry for the ZTS90DS and ZKD90 wall ovens plus the ZSB9231 Advantium 240V, the last with LCD controls. All three are current models.
Monogram wall oven repair in San Francisco
F-code back after the power disconnect? Call (415) 318-7427 from San Francisco or the Bay Area. Write down the complete code on the LCD, the model number and what you tried first. Monogram wall oven repair has further detail.
Model compatibility: Monogram reuses codes across series and model years, so F— plus number or letter may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
An F plus a number or letter on the LCD is a generic function error code; the manual defines no individual F-codes and gives one reset routine.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
