Error Code tC
Your dryer's temperature sensor isn't reading correctly
Moderate
Address soon - your appliance may not work properly
Also displayed as: tC
What This Means
Clogged lint screen restricting airflow and causing abnormal temperature readings; Restricted vent system causing heat buildup and abnormal thermistor readings; Thermistor 1 resistance out of range (open or shorted); Faulty wiring connection between thermistor and main PCB
What actually causes this:
Usually a clogged lint screen or blocked exhaust vent — restricted airflow causes the sensor to misread temperatures.
First Thing to Check
Pull out the lint screen and clean off all the lint, then check that your exhaust vent hose isn't kinked or blocked.
Parts Involved
How to Fix
- 1
1. Check for a clogged lint screen and clean if necessary
- 2
2. Check if the vent system is restricted — inspect exhaust duct for blockages or excessive length
- 3
3. Measure the thermistor resistance: should be 10K ohm at 25 deg C (77 deg F)
- 4
4. If thermistor resistance is infinite or very low, replace the thermistor
- 5
5. Check wiring harness between thermistor and main PCB for loose or damaged connections
