Troubleshooting

The Labcyte chiller has two system alarms that are shown on the chiller
display: RTD OPEN or RTD SHORT, FAN FAIL.
RTD OPEN or RTD SHORT: The connector has come loose or the
temperature sensor has failed. Turn off the chiller, reconnect the cable, and
turn it back on. If the alarm persists, turn off and unplug the chiller, and
then contact Labcyte Service and Support.

FAN FAIL: The fan is too slow to cool the chiller components or has
stopped. The fan is either blocked or has failed. Check for obstructions to
the side air inlet or outlet gratings of fan. Ensure there is at least a 3 inch
clearance around the fan. If there are no obstructions to the air flow, the
fan may be failing. Contact Labcyte Service and Support.
