Compensation Sensor Open

The ambient-compensation sensor (NTC) on the FLM board in the
has failed (open circuit).
The resistance across the temperature compensation sensor (NTC) on the FLM
board is dependent on ambient temperature. The change in resistance is used
by the leak circuit to compensate for ambient temperature changes. If the
resistance across the sensor increases above the upper limit, the error
message is generated.
Probable Causes
• Defective FLM board.
Suggested Actions

Exchange the FLM board.
