Error 16896 - Saturation Temperature Underrange
The indicated saturation temperature is below -10 °C (14 °F). Suspect misalignment or
malfunction of the saturation temperature probe.
Error 17408 - Presaturation Temperature Underrange
The indicated presaturation temperature is below -5 °C (23 °F). Suspect misalignment or
malfunction of the presaturator temperature probe.
Error 18432 - Expansion Valve Temperature Underrange
The indicated expansion valve temperature is below -10 °C (14 °F). Suspect
misalignment or malfunction of the expansion valve temperature probe.
Error 20480 - Chamber Temperature Underrange
The indicated chamber temperature is below -10 °C (14 °F). Suspect misalignment or
malfunction of the chamber temperature probe.
Error 24576 - Reference Temperature Underrange
The temperature reference resistor is below its nominal value of 0 °C (32 °F). This
typically indicates a faulty reference resistor or malfunctioning STD-A/D converter
board.
Error -16384 - Cabinet Temperature Overrange
The measured cabinet temperature is too high. Most likely causes include a blocked or
clogged intake vent on the left side of the unit, a blocked outlet at the back of the unit, or
a faulty fan.
Error -24576 - Reference Temperature Overrange
The temperature reference resistor is well above its nominal value of 0 °C (32 °F). This
typically indicates a faulty reference resistor or malfunctioning STD-A/D converter
board.
Error -28672 - Chamber Temperature Overrange
The indicated chamber temperature is above 100 °C (212 °F). Suspect misalignment or
malfunction of the chamber temperature probe.
Error -30720 - Expansion Valve Temperature Overrange
The indicated expansion valve temperature is above 100 °C (212 °F). Suspect
misalignment or malfunction of the expansion valve temperature probe.
Error -31744 - Presaturation Temperature Overrange
The indicated presaturation temperature is above 100 °C (212 °F). Suspect misalignment
or malfunction of the presaturator temperature probe.
