What CX means
When you see CX on Monogram 30-inch single and double convection wall ovens in the ZET1 and ZET2 series, such as the ZET1PL1SS and ZET2SL1SS, it stands for a communication error between boards in the oven. The documented order is to check the harness first, then replace the board named by the specific code from C1 through C6. A stored CX is not shown to the owner. What you may notice is a control that stops responding, a temperature that does not match what you set, or an oven that fails to start.
Common causes of CX
- Harness connection between boards
- Board named by the specific C1 to C6 code
- Temperature or mode encoder board
- Relay board communication
1. Switch the oven off at the controls. 2. Wait a few minutes, then turn it on and try a simple bake. 3. Note whether the temperature you set matches what the display shows. 4. If it behaves oddly, call us and report what you saw.
- The harness comes first, so we check every plug between the boards before any board is replaced.
- We read the specific C code to learn which board stopped answering.
- The price comes in writing in advance, and the work carries a 30-day workmanship warranty.
Other Wall Oven codes
Is CX one single error?
It is a family. The digit after C tells us which board stopped communicating, from C1 to C6.
Do I have to replace a board?
Not at first. The harness connections are checked before any board is replaced.
Why can't I see it?
These codes are stored and not displayed, so we read them from the control.
Still seeing CX?
A technician diagnoses it on site and gives you the price in writing before any work starts.
