What F-co means

F-co is a menu, not an error, on Monogram ZGP professional gas ranges such as the ZGP486ND. It sits inside the factory test mode, where the Timer display cycles to F-co and shows the last seven stored F codes. Technicians use it to see what the control has recorded. Owners seldom need it, and it is reached by the same knob hold that starts the Prod test mode shortly after power-up. If you see it unexpectedly, the mode was entered by accident.

Common causes of F-co

Test mode entered by holding the Push To Select knob after power-up
A technician reading the stored codes
Accidental entry while resetting the breaker

✓ One safe check you can try

1. Do not use any oven function while F-co is shown. 2. Hold the Push To Select knob for about three seconds to exit. 3. Turn the oven off if the display does not clear. 4. Call us if it keeps coming back.

! Why to stop there

Reading the stored codes is a technician job, and we interpret them together with how the range behaves
A code in the list may be old, so we see whether it repeats
We use the list to decide what to test, not to order a part

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

F-coF-co questions

What does F-co show?

The last seven F codes the control has stored. They are a history, not a live problem, so an old code in the list does not mean the problem is happening now.

Is it safe to look at?

It is harmless to look at, but the test mode can run loads on its own. We prefer to enter it ourselves with the range ready.

How do I leave it?

Hold the Push To Select knob for about three seconds. If the display stays, turn the oven off at the controls and call us, and do not try to run a cycle meanwhile.
