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 SSI5R (SI6R) does not
appear to be working correctly. 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

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...
