What Does Error E5 Mean?

The Haier oven error E5 signifies a malfunction of the temperature sensor, specifically a short circuit in the NTC (negative temperature coefficient) sensor on the main board. This issue leads to erratic temperature readings and can cause the oven to fail to heat properly or stop functioning altogether. Immediate troubleshooting is recommended to determine if the sensor or main control board needs replacement.

Common Symptoms:

  • Oven displays E5 on control panel
  • Oven fails to heat properly or stops operation when code appears

Possible Causes

  • Temperature sensor short circuit on main board (NTC short) (high)

How to Fix Error E5

DIY Fix Power cycle and basic checks

  1. Turn off the oven and unplug it from the power source.
  2. Wait for 5–10 minutes and then plug the oven back in and turn it on.
  3. Observe if the E5 code still appears.
  4. Ensure the oven has been properly preheated and that oven door is fully closed.

Technician Only Test and replace temperature sensor or main control board

  1. Disconnect power and access internal oven control area.
  2. Use a multimeter to test the resistance of the main board NTC temperature sensor to check for short circuit conditions.
  3. If sensor is shorted or out of specification, replace the temperature sensor.
  4. If sensor tests good, inspect wiring harness and main control board for shorts or faults and replace the main control board if necessary.

Parts needed: NTC temperature sensor, Main control board, Wiring harness

🛑 When to Call a Pro:
  • If the oven continues to show E5 after power cycling and basic checks
  • If any internal component tests indicate shorts or wiring damage
  • If you are not experienced with electrical diagnostics and internal oven repairs
