How to Fix / Troubleshooting

Safety first: Disconnect power before accessing sensors.

  • Locate ambient sensor: Find the Adler ambient thermistor, typically mounted near the air intake or control compartment.
  • Inspect wiring: Check that the thermistor harness is securely connected and not damaged.
  • Measure resistance: At room temperature, test the thermistor with a multimeter and compare to Adler specifications. Infinite or zero resistance indicates failure.
  • Replace thermistor: Install a new Adler ambient thermistor if readings are out of range, routing the wire away from hot or moving parts.
  • Reset and test: Restore power and verify that E16 clears and the unit operates normally.
