What E118 Means
E118 (sometimes shown as F118) typically appears when the oven can't read the temperature sensor correctly, due to sensor failure, wiring issues, or a communication problem between the sensor and the control board.
Common Causes of E118
- Failed temperature sensor
- Damaged or disconnected sensor wiring
- Control board failing to process the sensor signal
🔧 One Safe Check You Can Try
There isn't a safe at-home test — this requires multimeter testing of the sensor circuit on a de-energized oven.
⚠ Why You Shouldn't Go Further Than That
- This fault is easy to confuse with a heating element issue, and replacing the wrong part is a common, expensive mistake.
- Testing the sensor circuit requires a de-energized oven and a multimeter; skipping proper power isolation is a shock risk.
- The sensor sits inside the cavity near the broil element — removing it without care can damage the surrounding insulation.
- A sensor reinstalled even slightly out of its original position can continue reading inaccurately even though the part is technically working.
- Cavity access to reach the sensor typically voids the remaining warranty on the oven.
