Maytag Dryer Error Code tS

The tS code means the dryer's control board has detected a very low resistance reading from the thermistor, indicating the sensor circuit appears to be shorted. The thermistor is responsible for monitoring drum air temperature during operation. This fault causes the dryer to stop functioning normally until the problem is resolved.

No. The tS code means the dryer cannot accurately monitor drum temperature, which removes an important safety control from operation. Running the dryer without a functioning thermistor creates a risk of overheating. The fault should be diagnosed and repaired before resuming normal use.

Resetting the dryer by disconnecting power for a few minutes may temporarily clear the displayed code, but it will return as soon as the control board reads the shorted thermistor again. A reset does not fix the underlying electrical or component fault. The thermistor, wiring, and vent system need to be inspected and repaired to permanently resolve the error.

Some steps are DIY-friendly, such as cleaning the lint screen, checking and clearing the vent system, and inspecting the thermistor wiring for visible damage. Testing thermistor resistance with a multimeter is also something a confident DIYer can handle. However, replacing the thermistor or control board requires basic appliance repair skills and comfort working with electrical components.

If the thermistor itself is the problem, parts typically range from around $10 to $40, making it one of the more affordable repairs. If the issue is a wiring harness or connector problem, costs depend on the extent of the damage and whether a technician is needed. A control board replacement is significantly more expensive, generally ranging from $100 to $300 or more for parts alone.
