AEG 120-082-005
Part Number: 120-082-005
Product Introduction:
The 120-082-005 is a high-precision NTC thermistor used in AEG ovens and cooktops for surface temperature monitoring and safety cut-off functions. It is a critical safety component that triggers the main control board to shut off power if temperature exceeds the safe threshold.

Installation Requirements:
- Insert probe into designated sensor port in oven cavity wall
- Ensure full insertion — probe tip must contact cavity wall
- Route wires away from heating elements and fan motor
- Secure with brass compression fitting (provided)
Usage Precautions:
- Do not use multimeter in resistance mode on live circuit — risk of damage to control board
- Replace only with AEG 120-082-005 or exact equivalent (10kΩ / B3950)
- After replacement, perform oven calibration via service menu
- Probe sheath must not be kinked — minimum bend radius: 20mm
- Shelf Life (Unused): 5 years from manufacture date (store at 15–25°C, <60% RH)
