Maytag Washer Error Code T-19

The T-19 code on a Maytag washer indicates a water temperature error. The control board has detected that the water temperature is outside the acceptable range for the selected cycle. This typically points to a problem with the temperature sensor, the wiring connected to it, or the water supply itself. The washer will stop the cycle until the issue is resolved.

It is not recommended to continue running the washer while this error is active. The washer may not be washing at the correct temperature, which can result in clothes not being cleaned properly or fabric damage in certain cycles. Continuing to operate the machine without resolving the fault could also mask a worsening component failure. Address the error before running additional loads.

A reset may temporarily clear the T-19 code, but if the underlying problem is not fixed, the error will return during the next wash cycle. To reset the washer, unplug it from the power outlet for one to two minutes, then plug it back in. Use a reset only as a diagnostic step to confirm the code reappears, not as a permanent solution. The root cause must be diagnosed and repaired to prevent the error from recurring.

Start by confirming that both your hot and cold water supply valves are fully open and that water pressure is normal. Next, inspect the temperature sensor and its wiring harness for damage, corrosion, or loose connections. If the wiring looks intact, test the thermistor with a multimeter to check whether its resistance is within an acceptable range. If the sensor is faulty, replacing it is typically the fix, though in rare cases the control board may need to be replaced.

Repair costs depend on which component has failed. Replacing a thermistor or temperature sensor is generally an affordable repair, with parts typically ranging from $15 to $60 and professional labor adding $80 to $150 depending on your area. If the control board is the source of the problem, parts alone can range from $100 to $300 or more. Checking the wiring and water supply first costs nothing and may resolve the error without any parts.
