Symptom / Description

FAULT

Castor COB Series / Forno Multifunzione Oven: Food meat probe circuit error F105; internal temperature sensing probe jack shorted, open, or reading abnormal resistance.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Castor (Castor COB Series / Forno Multifunzione 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).

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Unplug 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 Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect 230V electrical mains power before removing appliance side or rear panels.
!Ensure tub water or heating chamber has cooled below 30°C before unclipping thermistor probe.
!Use CAT III 600V/1000V insulated test probes when tng at PCB edge connectors.

3. Preliminary Mechanical & Visual Checks

Inspect sensor immersion sleeve for calcification, limescale scale, or thermal paste degradation.
Check wiring harness for pinch points, chafing against chassis metal, and terminal pin oxidation.
Verify probe is firmly seated in its rubber grommet or bracket inside the water/air circuit.

Frequently Asked Questions: Castor F105

FAQ TREE

What does error code F105 mean on a Castor appliance?

Castor error code F105 indicates: Castor COB Series / Forno Multifunzione Oven: Food meat probe circuit error F105; internal temperature sensing probe jack shorted, open, or reading abnormal resistance..

What is the root cause of Castor error code F105?

The primary root cause for Castor code F105 is: On Castor (Castor COB Series / Forno Multifunzione 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)..

How do I fix or resolve Castor error code F105?

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 Reset keys for 5 seconds until the display clears the alarm code and restores standby status.

Is it safe to clear Castor error code F105 by resetting power?

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

How do I test electrical resistance for Castor code F105 using a multimeter?

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..

What safety protocol must be followed before servicing Castor code F105?

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.
