DIY Fix Basic power reset and check
- Turn off the oven at the circuit breaker or unplug it completely.
- Wait 1–2 minutes to allow residual charge to dissipate.
- Restore power and see if the E126 code clears.
Technician Only Inspect internal temperature sensor and wiring
- Remove access panel and locate oven temperature sensor probe.
- Visually inspect sensor and associated wiring for damage or loose connections.
- Measure sensor resistance with a multimeter; typical sensor values ~1100 Ω at room temperature (may vary by model).
- Replace sensor if out of expected range or showing intermittent readings.
Parts needed: temperature sensor probe, wiring harness
