Error Code E rt

Defect of room temperature sensor (RT sensor) — short-circuit or disconnection

Moderate

Address soon - your appliance may not work properly

Also displayed as: E rt

How to Fix

  1. 1

    Step 1: Check connector between Main PCB and RT sensor for loose or disconnected harness.

  2. 2

    Step 2: Measure RT sensor resistance. At room temperature (~70°F/21°C), sensor should read approximately 10kΩ.

  3. 3

    Step 3: If resistance is 0 ohm (short circuit), replace the RT sensor.

  4. 4

    Step 4: If resistance reads OL/infinite (open circuit), replace the RT sensor.

  5. 5

    Step 5: If resistance is within spec but error persists, replace Main PCB.
