Error Code Explained
What Does the Wolf SENSOR FAULT Error Code Mean?
A Wolf warming drawer temperature sensor fault means the thermistor used to regulate drawer temperature is reading an invalid value — either open-circuit (failed high) or shorted (failed low). The electronic control cannot regulate temperature correctly, causing the drawer to operate at incorrect temperatures or fail to maintain heat.
Root Causes
Common Causes of the Wolf SENSOR FAULT Error Code

1Failed NTC ThermistorThe temperature monitoring thermistor has failed open or short — the control receives an invalid resistance reading.
-
2Loose or Corroded Thermistor Wiring ConnectorThe connector at the thermistor or control board has corroded or come loose, creating an intermittent or open circuit.

FAQ
Frequently Asked Questions — Wolf SENSOR FAULT
-
A failed temperature sensor causes the drawer to run continuously hot (element always on) or stay cold (element never activates). Our technician measures thermistor resistance — a correct reading at room temperature is a specific resistance value; deviation indicates sensor failure.
