Compressor discharge pipe thermistor open or short circuit
Moderate
Address soon - your appliance may not work properly
Also displayed as: tE3
How to Fix
- 1
Check the 2-wire white housing connector for the compressor discharge thermistor on Main PCB (see PCB layout page 54); ensure it is fully seated.
- 2
Measure thermistor resistance terminal-to-terminal. Normal value is 10 kΩ ± 1% at 25°C (230 kΩ nominal also listed at 25°C — verify against live reading). If out of range, replace compressor discharge pipe thermistor (R code: C365).
- 3
If connector and thermistor are good, inspect wire harness for opens or damage; replace harness (R code: A190) if defective.
- 4
If all above check out, replace Main PCB (R code: A160).
