Whirlpool Oven: error codes during preheat
What is this symptom?
If your Whirlpool oven displays error codes during preheating, it can be frustrating. Common codes like F1, F2, and F3 may indicate issues such as a faulty temperature sensor or control board failure. Understanding these codes can help you troubleshoot and restore your oven's functionality.
Important Tips for Whirlpool Models
- Whirlpool ovens use both F- and numeric codes; specific diagnostic values and meanings are in official documentation and vary by model.
Possible Causes
Temperature sensor fault or disconnection
How to Identify: Error codes related to temperature (e.g., F3, 3d11 codes indicating sensor open/short or inability to reach/preheat temperature.
Part: Oven temperature sensor
Control board or electronic control failure
How to Identify: Error codes like F1 or control errors (e.g., EEPROM errors 1c6c and persistent codes after reset; oven won’t preheat properly.
Part: Electronic control board (Oven control PCB)
Keypad or button/control panel issues
How to Identify: Codes like F2/E0 or key circuit errors; unresponsive buttons or stuck keys accompanying error.
Part: Keypad/touch panel
Wiring or connection problems
How to Identify: Intermittent errors, codes return after reset, visible loose or damaged wires inside control panel or sensor harness.
Part: Internal wiring harness between components
Door lock mechanism interfering with preheat
How to Identify: Error codes related to door lock (e.g., F9 and oven refusing to start heat cycle due to lock engaged incorrectly.
Part: Door lock/latch assembly
DIY Solutions
Power reset to clear transient error
- Turn off power at circuit breaker or unplug oven.
- Wait 60 seconds.
- Restore power and attempt to preheat again.
Inspect and test temperature sensor
- Disconnect power to oven.
- Locate the temperature sensor inside oven cavity.
- Disconnect sensor and measure resistance.
- If open/short reading, replace sensor.
- Reassemble and test preheat function.

User Suggested Solutions
-
Check and replace the temperature sensor if faulty. To do this, unplug the oven, locate the sensor (usually at the back of the oven), disconnect it, and replace it with a new one. Reconnect and test the oven.
-
Inspect the control board for signs of damage or malfunction. If damaged, replace the control board. This involves removing the oven's back panel, disconnecting the old board, and installing a new one.
-
Examine the wiring and connections for any loose or damaged wires. Tighten or replace any faulty wiring. Ensure the oven is unplugged before performing this check.
