What Does Error F5 Mean?

The F5 error code on your Monogram oven indicates a malfunction within the temperature sensor or an issue with the relay drive circuit. This can lead to erratic temperature readings, failure to heat, or the oven not completing its cycles. Ensure the oven door closes properly, as door-related faults may also trigger this error.

Common Symptoms:

  • Oven displays F5 and may not operate normally
  • Oven may shut off or refuse to start when F5 appears
  • Door-related faults reported by some community sources

Possible Causes

  • Loss of relay drive circuit controlling oven functions (medium)
  • Faulty or misaligned door safety switch (low)
