Solving Problems
Should the proper function of your unit come into
question, use this section to help you determine what
the problem is and how to fix it.
Check if your question is similar to those listed below.
Then follow the guidelines found in that section:
 The temperature control inside the unit does not
appear to be working correctly. What’s wrong?

The refrigeration of my unit does not appear to be
working co
rrectly. What’s wrong?
WARNING
Replacing fuses with wrong type and value can
result in serious damage to the equipment and
property. ONLY Replace fuses with the same type
and amperage indicated on the replacement fuse
labels.
There are no user serviceable components inside
the unit. Potentially lethal voltages exist. Do not
attempt to service your unit beyond the procedures
described here. See “Getting Your Unit Serviced on

1. Wait for the temperature
indicated by the Main
Temperature Controller to
stabilize. If you have just turned
the unit on, wait 24 hours for the
incubator to stabilize at a
warmer temperature. A
fluctuation of no more than + 0.1

C is normal.
If this is not the problem...
2. Recalibrate the Main
Temperature Controller. See
page 11.
If this doesn’t solve the
problem...
3. Be sure your reference
thermometer is certified.
If this is not the problem...
4. Turn the OTP fully clockwise.
