Westinghouse F105

Westinghouse error code F105 indicates: Westinghouse Elevate / Multi-Function Built-in Oven: Food meat probe circuit error F105; internal temperature sensing probe jack shorted, open, or reading abnormal resistance..

The primary root cause for Westinghouse code F105 is: On Westinghouse (Westinghouse Elevate / Multi-Function Built-in Oven) models: Grease or moisture penetration inside probe cavity jack, damaged silicone cable on meat probe needle, or open PT1000 sensor inside probe tip (~1079 Ω at 20°C)..

To resolve error code F105: Unplug meat probe from cavity socket. Clean socket contacts with isopropyl alcohol. Measure probe resistance across plug pins with multimeter (~1079 Ω at 20°C). Press Start/Pause together with Temp button for 5 seconds to exit service diagnostic mode and clear persistent EEPROM alarm.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Westinghouse code F105 persists, the physical component causing On Westinghouse (Westinghouse Elevate / Multi-Function Built-in Oven) models: Grease or moisture penetration inside probe cavity jack, damaged silicone cable on meat probe needle, or open PT1000 sensor inside probe tip (~1079 Ω at 20°C). must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
