What TC5 / TC7 / TC8 / TCA / TCB means

These codes appear on the Samsung WD53DBA900H-series Bespoke AI Laundry Combo, for example the WD53DBA900HZA1. Each one names a thermistor in the drying system whose reading is out of range: TC5 the discharge refrigerant thermistor, TC7 the evaporator inlet thermistor, TC8 the evaporator outlet thermistor, TCA the compressor top thermistor and TCB the heater thermistor. You will see the code and the drying function stops.

Common causes of TC5 / TC7 / TC8 / TCA / TCB

  • The named thermistor itself
  • Connector or wiring at that sensor
  • Blocked filter or airflow raising temperatures
  • Main board input
✓ One safe check you can try

1. Write down which of the five codes you see. 2. Turn the unit off and let it cool. 3. Clean the lint filter and check for airflow around the unit. 4. Do not open any panel or touch the drying parts. 5. Call us with the exact code.

! Why to stop there
  • The code identifies the sensor circuit but not whether the sensor, its wiring or the board is the cause.
  • We test the named sensor and its connection before recommending a part.
  • Any sensor repair is quoted in writing first, and the work comes with a 30-day warranty.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

TC5 / TC7 / TC8 / TCA / TCBTC5 / TC7 / TC8 / TCA / TCB questions
Do the five codes mean different problems?

Each points to a different sensor. TC5, TC7 and TC8 sit in the refrigerant and evaporator path, TCA on the compressor and TCB on the heater. Tell us the exact one.

Can I keep washing?

Often yes, but avoid drying until we have checked it. The code concerns drying sensors, not the wash circuit. Keep clothes that need drying on a rack for now, so you avoid putting the sensors under more strain.

Will cleaning the filter help?

It can reduce heat in the drying path. If the code returns after cleaning, we test the named sensor and wiring. A clean filter is simple and safe, and it helps rule out airflow before we test the sensors.
