What Does Error F03 Mean?

The AEG oven F03 error code indicates a malfunction in the temperature sensor or its circuit, resulting in erratic temperature readings and potential failure to heat properly. This error may appear immediately when powering on the oven or during preheating. If the issue persists after a power reset, it suggests a deeper problem within the temperature sensing circuitry or control communication, necessitating further diagnostics or repair.

Common Symptoms:

  • Oven fails to start a cooking cycle
  • Error F3 appears on display immediately at power‑on or during preheat
  • Oven does not heat or maintains temperature control
  • Reset or power cycle does not clear the code

Possible Causes

  • Temperature sensor circuit fault (medium)
  • Intermittent or failed communication between sensor and control board (medium)

How to Fix Error F03

DIY Fix Perform a power reset and simple checks

  1. Turn off the oven at the mains or fuse box
  2. Wait at least 30 seconds and restore power
  3. Try restarting the oven to see if the error clears again

Technician Only Diagnose temperature sensor and circuit

  1. Disconnect power to the oven
  2. Remove access panels to reach the oven’s temperature sensor and wiring
  3. Inspect sensor wiring and connectors for looseness or damage
  4. Test the sensor’s resistance with an appropriate multimeter to check for open or incorrect readings
  5. If sensor or wiring is faulty, replace as needed
  6. If sensor and wiring check out, evaluate the oven control board’s input circuitry

Parts needed: temperature sensor (RTD/probe), wiring harness, control board

🛑 When to Call a Pro:
  • If the error persists after power reset
  • If you are uncomfortable performing electrical diagnostics
  • If internal components (sensor/wiring/control board) are suspected faulty
