What Does Error 2 Mean?

The Hisense Air Conditioner error code 2, often displayed as E2, indicates a malfunction in the temperature sensing system, typically related to the evaporator or indoor coil temperature sensor. This can cause the AC to stop cooling or heating effectively, leaving the fan running. It may also produce unusual noises as a symptom of the fault. A loose or damaged sensor wiring connection can exacerbate the issue, leading to a need for inspection and potential repair.

Common Symptoms:

  • AC stops cooling or heating when error appears (may leave fans running)
  • Error code displayed on indoor unit panel or remote control indicating E2 condition

Possible Causes

  • Evaporator/indoor coil temperature sensor fault (medium)
  • Sensor wiring connection issue (loose, damaged) (medium)

How to Fix Error 2

DIY Fix Basic checks before service call

  1. Turn off power to the unit and wait a few minutes, then restart to see if the error clears (power reset)
  2. Ensure indoor unit filters and vents are clean and not obstructed, improving airflow and reducing sensor misreads

Technician Only Inspect and repair temperature sensing system

  1. Check the resistance and proper function of the evaporator/indoor coil temperature sensor(s).
  2. Inspect and secure sensor wiring harnesses and connectors; repair or replace damaged wiring.
  3. Replace faulty temperature sensor components if needed.

Parts needed: Temperature sensors (indoor/evaporator), Sensor wiring harness
