Compensation Sensor Open
The ambient-compensation sensor (NTC) on the FLM board in the
(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.
