Oven shows E025, often on models with core temperature probe, and probe functions are disabled

Safety: Disconnect power before accessing internal wiring.

• Remove probe: Unplug the core temperature probe from its socket and inspect the plug and socket for corrosion, food residue, or moisture.
• Clean socket: Gently clean the socket with a dry cotton swab. Allow it to dry completely.
• Test without probe: Restore power and check if E025 disappears when the probe is not connected. If so, the probe itself is likely faulty.
• Probe resistance test: Measure resistance across the probe contacts. Compare to specifications (typically a few kΩ at room temperature). Infinite or zero resistance indicates a bad probe.
• Inspect internal wiring: If E025 persists with no probe connected, inspect the wiring from the socket to the control board for shorts or damage.

Recommendation: Replace the core temperature probe if it tests faulty. If wiring is intact and the error persists, the control board probe circuit may need replacement.
