Thermal Error — thermistor resistance output abnormal

Moderate

Address soon - your appliance may not work properly

Also displayed as: tE

What This Means

Wiring connection fault; Thermistor out of spec or failed

How to Fix

  1. 1

    Step 1: Check connectors RD6 and WH4 at main PCB for disconnection; reconnect if loose.

  2. 2

    Step 2: Measure thermistor resistance — should be 8-44kΩ (resistance decreases as temperature increases). If out of range, replace thermistor.

  3. 3

    Step 3: Measure voltage at RD6 pin3~NA8 pin3 — should be 1-3V DC. If absent or out of range, replace main PCB assembly.

  4. 4

    Step 4: If thermistor and wiring are correct, replace main PCB assembly.
