What F Code on LCD Screen means
On Monogram 30-inch Direct Air convection wall ovens with the LCD control, such as the ZTS90DSSNSS single and double models, a message starting with F followed by a number or letter is a function error code. The owner's troubleshooting chart describes it only in those terms and does not print a list of individual codes, so the characters after the F are what we use to narrow down the circuit involved. The F code shows on the LCD screen, and the oven may stop heating until the message is cleared.
Common causes of F Code on LCD Screen
- The exact characters shown after the F, which we write down first
- Oven temperature sensor circuit and its connector
- Control board reading a sensor or latch outside its range
- A one-time event that clears once the oven has cooled
1. Touch Dismiss on the LCD screen and note the characters after the F. 2. Let the oven cool for one hour, then put it back into operation. 3. If the code returns, switch the oven off at the breaker for 30 seconds and switch it back on. 4. If the same code shows again, stop using that cavity and call us with the code.
- The F code alone does not say which circuit tripped, so we read the full characters and watch how the oven behaves
- We test the sensor and latch wiring before any part is recommended
- A repeat after the power reset points to a real circuit problem rather than a one-time event
Other Wall Oven codes
Does every F code mean the oven is broken?
No. Some appear once and clear after the oven cools. A code that comes back after cooling and a power reset is the one we want to look at.
Can I keep baking with the code showing?
Dismiss it and try again after an hour of cooling. If the oven refuses to heat or the code returns right away, stop and have us check it, because the cause may be a temperature sensor.
What should I tell you when I call?
Give us the model number, the exact characters after the F, and whether the oven was heating, cleaning or idle when it appeared. That lets us bring the right parts to a ZTS90.
