TROUBLESHOOTING
FOR PERSONAL SAFETY, ALWAYS DISCONNECT THE POWER BEFORE SERVICING. Always
make a visual inspection of the incubator and control panel when troubleshooting. Look for loose or
disconnected wires that may be the source of the trouble.
TEMPERATURE
Temperature too high
1/ controller set too high.
2/ controller failed on
– call Customer Service
Temperature too low
1/ controller set too low.
2/ unit not recovered from door opening
– wait for heating indicator to turn off.
3/ unit not recovered from power failure or being turned off – incubators will need 2
hours to warm up and stabilize
Unit will not heat over a temperature that is
below set point
Check calibration – using reference thermometer.
Unit will not heat up at all
1/ verify that controller is asking for heat by looking for Heating indicator light – if
pilot light is not on continuously during initial start-up, there is a problem with
the controller.
2/ has the fuse/circuit breaker blown?
Indicated chamber temperature unstable
1/ ±0.1 may be normal.
2/ is ambient radically changing
– either door opening or room airflow from heaters
or air conditioning? – stabilize ambient conditions.
Will not maintain set point
1/ assure that set point is at least 5 degrees over ambient room temperature.
MECHANICAL
Door not sealing
1/ check physical condition of gasket
2/ assure that gasket is in original location
3/ Verify that door latch is operating correctly and not miss-aligned or broken.
OTHER
Unit or wall fuse/circuit breaker is blown
1/ check wall power source.
2/ see what other loads are on the wall circuit.
3/ has the circuit breaker on the front panel been tripped?
Unit will not turn on
1/ check wall power source
2/ check fuse/circuit breaker on unit or in wall
3/ check all wiring connections, esp. around the on/off switch
Unit is smoking – out of box
This is not an uncommon occurrence when the protective coatings heat up during
initial operation. Put unit under vent and run at full power for one hour until the
smoke dissipates.
Contamination in chamber
1/ see cleaning procedure.
2/ develop and follow standard operating procedure for specific application; include
definition of cleaning technique and maintenance schedule.
If following these troubleshooting suggestions does not solve the problem, call Customer Service for assistance.
Please see the manual cover for information on where to contact Customer Service.
