What Does Error E5 Mean?

The Amana air conditioner E5 error indicates a high pressure switch fault or abnormal sensor feedback detected by the control board. This issue often leads to a shutdown of the unit with a blinking display. The system enters protective mode when sensor readings are outside the expected range or if there are circuit irregularities. Common symptoms include the unit stopping operation and persisting error across power cycles.

Common Symptoms:

  • Unit stops operation and displays E5 on digital interface
  • Error persists across power cycles
  • Possible sensor‑related indications (e.g., abnormal temperature readings)

Possible Causes

  • Sensor feedback outside expected range or sensor circuit irregularity (medium)
  • Power supply or voltage input irregularities (low)

How to Fix Error E5

DIY Fix Basic checks and resets

  1. Turn off the air conditioner using the remote and wait for it to fully stop.
  2. Disconnect power at the breaker or unplug the unit for at least 5–10 minutes to allow control boards to reset.
  3. Restore power and attempt to restart the unit to see if the error clears.

Technician Only Inspect sensors and internal wiring

  1. Open the unit’s service panel following manufacturer safety procedures.
  2. Inspect temperature sensors and wiring harnesses for corrosion, loose connections, or damage.
  3. Test sensor readings and continuity with appropriate tools.
  4. Verify stable voltage input to the unit and inspect the control board for signs of electrical stress.

Parts needed: Temperature sensors, Wiring harnesses, Control board (if faults are found)

🛑 When to Call a Pro:
  • Error persists after power cycling and basic resets
  • Visible damage to wiring or components
  • Unstable power supply to HVAC unit
  • Unit does not respond to any user‑level actions
