h_shek,

The picture you posted is the actual sensor. Number "1" shows it's location. Number "2" shows the plug I disconnected and the fan speed went into LOW. I doubt if it's the connection since the speed changes when connected and disconnected.

At first I thought maybe I shorted the connectors together by getting it wet. Then I thought the fan should go to HIGH when the sensor is CLOSED, and back to LOW when the sensor is OPEN. When the connector is connected the fan is on HIGH, therefore, the sensor is CLOSED. When the connector is disconnected, the FAN is on LOW, therefore the circuit is OPEN (connector not shorted). It appears the connector is fine and the sensor may have gone bad.

If I get a hold of a digital multimeter, how should I check if the sensor is bad.

thanks,
