What Does Error E1 Mean?

The Mitsubishi Refrigerator E1 error code indicates a malfunction in the temperature sensor, leading to erratic temperature readings and potential cooling issues. If the E1 code appears, it may affect the refrigerator's ability to maintain the desired temperature, prompting users to check the sensor and electronic components for faults.

Common Symptoms:

  • E1 displayed on the refrigerator control panel
  • Refrigerator fails to maintain set temperature / cooling cannot be regulated (community pattern for generic refrigerators with E1)

Possible Causes

  • Temperature Sensor

How to Fix Error E1

DIY Fix Basic checks and reset

  1. Unplug the refrigerator from the power outlet for 5–10 minutes to perform a power cycle.
  2. Plug it back in and see if the E1 code clears.
  3. Ensure the refrigerator is receiving stable power and the plug is fully seated in the outlet.

Technician Only Inspection of temperature sensors and control electronics

  1. If the error persists after reset, a trained technician should inspect internal sensor circuits and wiring harnesses for faults, loose connections, or damage.
  2. Use a multimeter to test thermistor/temperature sensor resistance against expected values.
  3. Check the main control board for faults if sensors and wiring are normal.

Parts needed: Temperature sensors / thermistors, Wiring harnesses, Control board

🛑 When to Call a Pro:
  • If the E1 code persists after power cycling and basic checks
  • If internal inspection reveals wiring or board issues
  • If the refrigerator is not cooling properly despite attempts to reset
