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
