  • Cooling may stop or become erratic when the code is displayed
  • Inaccurate or no temperature regulation reported by users

Possible Causes

  • Room temperature sensor (thermistor) malfunction or fault (medium)
  • Loose or poor connection at the temperature sensor (medium)

How to Fix Error E1

DIY Fix Basic reset and environmental checks

  1. Turn off and unplug the portable air conditioner.
  2. Wait at least one minute to allow the internal electronics to reset, then plug it back in.
  3. Ensure the air intake and outlet are not blocked and that the filter is clean.

Technician Only Inspect and test the temperature sensor and wiring

  1. Access the internal control compartment to locate the room temperature sensor (thermistor).
  2. Check the wiring harness and connector for signs of looseness, corrosion, or damage.
  3. Test the sensor with a multimeter for appropriate resistance behavior relative to temperature.
  4. Replace the sensor if it is out of specification or clearly defective.
