Monogram ZET Wall Oven Code C5: lower encoder temperature link lost

Medium · inspection needed

Code: C5
Appliance: Wall Oven
Brand: Monogram
Warranty: 30-day workmanship

What C5 means

Found on double ovens in Monogram 30-inch single and double convection wall ovens in the ZET1 and ZET2 series, such as the ZET1PL1SS and ZET2SL1SS, C5 is a stored record of lost communication with the lower temperature encoder, the board that reads the temperature setting for the lower oven. A documented sign is that the initial set temperature differs from the one you selected, which points to replacing that encoder board. The display does not show C5.

Common causes of C5

Lower temperature encoder board
Harness to the encoder
Set temperature differing from the selected value
Control board communication

✓ One safe check you can try

1. Switch the lower oven off and let it cool. 2. Set a bake on the lower oven and compare the temperature shown with your choice. 3. Write down any mismatch. 4. Call us if the numbers disagree and give us both temperatures.

! Why to stop there

We compare selected and shown temperatures on the lower oven first.
The harness is inspected before we replace the encoder board.
You get a written price before work, with a 30-day workmanship warranty.

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.

C5C5 questions

How does C5 differ from C2?

C2 involves the upper temperature encoder and C5 the lower one, so C5 applies only to double ovens.

What would I notice?

The lower oven may start at a temperature that differs from your setting.

Is C5 shown on the display?

No. It is stored and read by a technician.
