Whirlpool Cooktop Error Code F-37

The F-37 error code on a Whirlpool cooktop indicates a Type 1 temperature sensor failure affecting a single burner. This is functionally identical to the F-36 fault in terms of the underlying failure mode. The temperature sensor is a thermistor, a resistive component whose electrical resistance changes predictably with temperature. At room temperature, a properly functioning sensor should measure between 184,000 ohms and 292,000 ohms. When the cooktop's control board reads a value outside this range, or receives no signal at all, it triggers the F-37 code and disables the affected burner as a safety measure.

The most common causes of this fault fall into two categories: a physical connection problem or an outright sensor failure. The sensor connector can work loose due to vibration from normal use, or the terminals can develop corrosion that increases resistance beyond the acceptable range. In other cases, the thermistor element itself degrades or fails open, producing a reading of infinite resistance that the board interprets as a sensor fault.

Diagnosing the F-37 code requires disconnecting power to the appliance before performing any resistance checks. With power removed, locate the temperature sensor connector for the affected burner, unplug it, and measure resistance across the sensor terminals with a digital multimeter. A reading between 184,000 ohms and 292,000 ohms confirms the sensor is functional and the fault is likely connection-related. A reading significantly outside that range, or an open circuit reading, points to a failed sensor that needs replacement.
