Possible Causes

Failed lower zone thermistor, Loose or corroded connector at control board, Damaged sensor wiring behind lower liner

How to Fix / Troubleshooting

Safety: Disconnect power before servicing. Use caution when working around sharp metal edges.

Steps to resolve E8:

  • Confirm affected zone: Verify that E8 corresponds to the lower zone on your NewAir dual-zone model. Note any cooling issues specific to that zone.
  • Locate the lower zone sensor: Inside the lower compartment, find the small sensor cover or probe on the back or side wall.
  • Inspect sensor and mounting: Remove any cover and check that the sensor is not loose, cracked, or corroded. Ensure it is not blocked by bottles or shelves.
  • Trace wiring: Follow the sensor wires toward the rear of the cabinet as far as accessible. Look for pinched or damaged insulation.
  • Access control board: Remove the rear or bottom panel to reach the main control board. Identify the lower zone sensor connector.
  • Check and reseat connector: With the unit unplugged, disconnect and reconnect the lower zone sensor plug. Inspect for moisture or corrosion.
  • Test sensor: Measure resistance of the sensor at room temperature and compare to NewAir’s specifications. Replace with a NewAir lower zone temperature sensor / thermistor if readings are abnormal.
  • Reassemble and test: Reinstall panels, restore power, and verify that the E8 code clears and the lower zone maintains the set temperature.

Note: Persistent E8 after sensor replacement may indicate a defective main control board, which should be replaced by a qualified technician.
