Kelvinator F105

Kelvinator error code F105 indicates: Kelvinator KOB Series / RoastMaster 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 Kelvinator code F105 is: On Kelvinator (Kelvinator KOB Series / RoastMaster 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). Hold Start and Cancel/Clear buttons together for 5 seconds until service diagnostic mode exits and clears memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Kelvinator code F105 persists, the physical component causing On Kelvinator (Kelvinator KOB Series / RoastMaster 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.
