What Does Error F8 Mean?

The Monogram oven F8 error indicates a malfunction related to the temperature sensor or communication fault within the control system. This error can cause the oven to fail to start, shut down during operation, or not heat properly. Inspect the temperature probe and wiring for any visible damage, as issues may arise from a shorted probe circuit or communication errors between the control board and other components.

Common Symptoms:

  • Oven may not start or shut down during operation when F8 appears.
  • Oven may fail to heat or complete selected cooking cycles.
  • Error persists even after simple resets (power cycling).

Possible Causes

  • Communication fault between the control board and internal components (medium)
  • Short or fault in temperature probe / probe circuit (medium)

How to Fix Error F8

DIY Fix Basic reset and inspection

  1. Disconnect power to the oven (unplug or shut off at breaker) for a few minutes, then restore to see if the error clears.
  2. Check that any temperature or cooking probes are fully inserted and not visibly damaged.
  3. Ensure vents and cooling pathways around the oven are not blocked.

Technician Only Diagnose control communication and probe circuitry

  1. Use a multimeter to check continuity of the oven’s meat/temperature probe and receptacle for shorts or open circuits.
  2. Inspect wiring harnesses between control board and sensors for damage, corrosion, or loose connectors.
  3. Test communication signals from the control board to internal boards/sensors; replace control board if confirmed faulty.

Parts needed: Temperature/probe harness and connector, Oven control board

🛑 When to Call a Pro:
  • If the error persists after resetting power and inspecting accessible wiring, or if there are signs of electrical damage (burn marks, melting).
  • If you are not comfortable testing electronic components safely.
