Thermistor Malfunction Error Indicators

The diagrams below illustrating what a customer may see on the display if there is a thermistor fault, such as a short
or open condition. (See Figures 3-25, 3-26, 3-27) A thermistor fault will cause power to the compressor and fans to
be cut, and error codes to be logged (covered later in this section). If the temperature alarm feature has been
enabled by pressing the bell key on the control panel, the BELL ON indicator will also flash, and the audible alarm
will beep.
NOTE: Correcting/repairing the thermistor problem will clear the Thermistor Malfunction Error Indicator.
