TC2
Samsung Washing Machine
Severity: ModerateWhat Does This Error Mean?
The TC2 error on a Samsung washer indicates a temperature control fault — specifically a problem with the cold water temperature circuit or a secondary thermistor reading. The machine detected a temperature that is out of the expected range and stopped the cycle as a safety precaution.
Affected Models
- WF45R6100AW
- WF50R8500AV
- WF45T6000AW
- WF56H9100AG
- Most Samsung front-load washers with heater
Common Causes
- Faulty secondary temperature sensor (thermistor) inside the drum
- Wiring harness to the thermistor is loose or damaged
- Cold water supply is too cold (below 41°F / 5°C) in winter months
- Main control board malfunction causing incorrect temperature readings
- Water heating element has failed and cannot reach target temperature
How to Fix It
-
Unplug the washer and wait 5 minutes before plugging it back in.
A control board glitch can sometimes trigger TC2 temporarily. A power reset often clears it if there is no real fault.
-
Check that the cold water supply is not unusually cold.
In very cold climates during winter, water entering the machine may be near freezing. The washer may struggle to heat it to the target temperature.
-
Make sure the washer is in a room above 50°F (10°C).
Samsung washers are not designed to operate in unheated garages or laundry rooms during freezing weather. Extreme cold affects the temperature sensor readings.
-
Run the washer on a warm or hot wash cycle to see if the error reappears.
If the error only happens on certain temperature settings, the heating element or that specific thermistor circuit is likely the problem.
-
If the error persists across all cycles, contact a technician to test the thermistor and heating element.
Both parts can fail and produce similar error codes. A multimeter test will reveal which one is out of spec.
When to Call a Professional
Temperature sensor and heating element replacements require disassembling the drum area. This is not a DIY repair for most homeowners. A technician can test both parts with a multimeter before ordering replacements. Expect repair costs of $150–$280 depending on which component is faulty.
Frequently Asked Questions
Is TC2 the same as TC on a Samsung washer?
They are related but slightly different. TC is a general temperature control error. TC2 points to a specific circuit or secondary sensor within the temperature control system. Both are fixed using the same diagnostic approach.
My washer shows TC2 only in winter — is that normal?
It can happen in very cold climates. If incoming cold water is near freezing, the washer may struggle to heat it fast enough and time out. Try running the machine in a warmer environment or during warmer parts of the day when groundwater is less cold.
Can I fix TC2 myself?
The power reset and water supply checks are easy DIY steps. Beyond that, accessing the thermistor requires opening the machine. Unless you are comfortable with appliance repair, it is safer to call a technician for internal component testing.
