Monogram Range F76 Error: Control communication fault
The F76 error on a Monogram range indicates a communication fault between the electronic oven control (EOC) board and the gas valve control or the surface burner control module. The two modules are not communicating correctly over the internal data bus.

Answer to continue safely
Is it safe to keep using?
No. Do not use the range when F76 is active. The communication failure means control signals between modules are unreliable, and cooking functions may behave unexpectedly. Disconnect power until the fault is diagnosed.
Can I reset the code?
Yes. A 5-minute circuit breaker reset may clear F76 if a power disruption caused a temporary communication loss. If the code returns after reset, board-level diagnosis by a technician is required.
When to stop immediately?
Stop if you notice: The range shows F76 immediately every time power is restored, Multiple error codes appear simultaneously on the display.
Symptoms You May Notice
Surface burners fail to ignite
Gas surface burners will not light or do not click for ignition, even when the oven is not in use.
Oven and surface controls both unresponsive
Both the oven and cooktop functions stop working simultaneously, indicating a loss of communication between control modules.
Range shuts down spontaneously
The range turns off all active cooking functions mid-use and displays F76 without any user input.
Error appears after a power surge or outage
F76 first displayed immediately after a power disruption such as a thunderstorm, power company outage, or breaker trip.
Possible Causes
Communication wiring harness fault
The ribbon cable or wiring harness connecting the EOC board to the secondary control module has a loose, broken, or shorted connection.
DIY PossiblePower surge damage to control module
A voltage spike has damaged the communication circuitry on one or both control boards.
Requires ProfessionalFailed EOC or secondary burner control board
One of the two control modules has failed and can no longer participate in the internal communication bus.
Requires ProfessionalSafe Checks You Can Do
-
1
Power Reset
Turn off the circuit breaker for 5 full minutes to allow all control module capacitors to discharge completely. Restore power and observe whether F76 returns.
A longer reset period (5 minutes rather than 60 seconds) gives the control modules more time to fully re-initialize their communication bus.

2
Check for Loose Harness Connections
Unplug the range. Access the control board area (typically behind the rear panel or under the cooktop, depending on model). Without disconnecting anything, visually inspect the ribbon cables and wire harnesses for connectors that appear partially pulled out or visibly damaged.
Even a connector that looks seated may have vibrated slightly loose. Press each connector firmly home and restore power to test.

Document Any Recent Events
Note whether the code appeared after a power outage, a tripped breaker, or a recent service visit. Share this information with the technician, as power surge damage often requires board-level diagnosis and component-by-component testing.
If you have a whole-house surge protector or the range is on a dedicated circuit without surge protection, mention this to the technician.
When to Call a Professional
Contact a qualified technician if:
- F76 returns immediately after every power reset
- Visual inspection reveals no loose connectors
- The code appeared after a confirmed power surge or lightning strike
