Maytag Washer Error Code 16

Error code 16 means the control board detected a possible open circuit in the thermistor, the sensor responsible for reading water temperature. An open circuit means the signal from the thermistor is completely absent rather than just out of range. The washer halts the cycle because it cannot monitor water temperature. The fault is most commonly a failed thermistor or a broken wire in the harness connecting it to the control board.

Start by unplugging the washer and locating the thermistor, which is typically mounted in the tub or on the water inlet assembly. Inspect the wiring harness and connector for visible breaks, pulled terminals, or corrosion and reseat any loose connections. Use a multimeter to test the thermistor for continuity; a reading of infinite resistance or no continuity confirms the thermistor has failed and needs replacement. If the thermistor tests good, trace the wiring harness back to the control board looking for a break or damaged connector.

Yes. Unplug the washer, disconnect the thermistor from the wiring harness, and use a multimeter set to measure resistance. A functioning thermistor will show a measurable resistance value that changes with temperature; the exact range varies by model but is typically in the thousands of ohms at room temperature. A reading of infinite resistance or open loop confirms the thermistor has failed and should be replaced. Testing the wiring harness for continuity between the connector and the control board is the next step if the thermistor itself passes.

Running the washer while code 16 is active is not recommended. Without a functioning thermistor, the control board cannot regulate water temperature, which means cycles that rely on temperature verification may not perform correctly and could potentially expose laundry to incorrect water conditions. The washer will typically stop the cycle and refuse to continue until the fault is cleared. Resolve the thermistor issue before resuming normal use.

A replacement thermistor for a Maytag washer typically costs between $15 and $50 for the part alone, making it one of the more affordable repairs if you can do it yourself. If the issue is a broken wire or connector repair, the cost may be minimal with no parts needed. Professional labor for a thermistor replacement generally runs $100 to $200 depending on your area and service provider. If the control board is the root cause, parts cost can rise to $150 to $350 or more.
