What Does Error CF2 Mean?
The LG oven error code CF2 indicates a malfunction in the left rear top temperature sensor, which can cause erratic temperature readings or prevent the oven from preheating. This issue often arises from an open or short-circuit fault in the sensor circuit, leading to inaccurate temperature detection during cooking or preheating cycles.
Common Symptoms:
- CF2 displayed on oven control panel
- Oven may fail to heat or report incorrect temperature readings
- Error may appear during preheat or cooking cycle
Possible Causes
- LR top sensor open circuit (medium)
- LR top sensor short circuit (medium)
How to Fix Error CF2
DIY Fix Power cycle and visual check
- Turn off the oven and disconnect power at the breaker or unplug.
- Wait a few minutes, then restore power to see if CF2 clears.
- Visually inspect accessible areas around the left‑rear top sensor for obvious damage or loose connectors (avoid internal exposure unless technically comfortable).
Technician Only Inspect and test LR top temperature sensor circuit
- Disconnect oven from power and remove necessary access panels to reach the LR top sensor.
- Visually inspect the sensor and wiring harness for damage, burns, or loose connections.
- Use a multimeter to test the sensor resistance and compare with expected values for that model.
- Replace the LR top sensor if open or shorted; repair or replace any damaged wiring.
- Reassemble, restore power, and verify that the CF2 fault no longer appears.
Parts needed: LR top temperature/condition sensor, wiring harness/connectors
- If you are not comfortable performing multimeter tests, accessing internal components, or working with mains voltage.
- If the fault persists after basic checks and power cycling, seek a qualified service technician.
