What Does Error F4 Mean?

The Magic Chef oven error code F4 indicates a malfunction in the temperature sensor, often due to an open or shorted sensor circuit. This results in inaccurate temperature readings, causing the oven to fail to reach the set temperature and possibly shut off unexpectedly during use. Check the sensor and its connections for damage to resolve this issue.

Common Symptoms:

  • Error code F4 displayed on control panel
  • Oven fails to heat to set temperature
  • Oven may shut off unexpectedly during operation

Possible Causes

  • Open or shorted oven temperature sensor (RTD) (high)
  • Damaged wiring / poor connector contact between sensor and control board (medium)
  • Faulty oven control board (after verifying sensor and wiring) (medium)

How to Fix Error F4

DIY Fix Check oven temperature sensor and connectors

  1. Disconnect power to the oven at the breaker.
  2. Locate the oven temperature sensor (usually in the upper back of oven cavity).
  3. Visually inspect sensor wiring and connector at the control board for damage, melts, corrosion, or loose pins.
  4. Measure sensor resistance at room temperature with a multimeter; typical RTD sensors read ~1100 ohms at ~25 °C (may vary by model).
  5. If resistance is extremely low (near 0) or infinite/open, replace the oven temperature sensor.

Technician Only Repair wiring or replace components

  1. With power off, trace sensor harness from sensor to control board, repairing any damaged insulation or connectors.
  2. Replace oven temperature sensor (RTD) if test shows open or shorted circuit.
  3. If sensor and wiring are verified good and F4 persists, replace the oven control board (ERC).

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

🛑 When to Call a Pro:
  • If uncomfortable performing internal electrical work
  • If error persists after replacing sensor and checking wiring
