• Shield the thermal cycler from heat sources such as radiators, heat producing
instruments, and bright sunlight.
Replacing Fuses
Fuses on the T100 thermal cycler are designed to blow in case of severe power surges or
other causes of electrical short. This process protects both the user and the instrument from
excessive electric charge. Fuses on the T100 thermal cycler rarely need to be replaced.
However, some institutions prefer to replace fuses on a regular basis to maintain uninterrupted
operation.
If the thermal cycler does not turn on, first check that the power cord is plugged into a
functioning power source. Also, check that the power cord and power source are within the
specifications for this instrument. To replace a power cord, contact Bio-Rad Technical Support
(for more details, see Bio-Rad Laboratories Resources on page
iii).
Finally, check that the fuses are intact. The T100 thermal cycler runs with two fuses (Figure 29).
To remove and check the fuses, follow these steps:
WARNING! To prevent electrical shock, always turn off the instrument and unplug
it from the electrical outlet before checking the fuses.
1. Use a small coin to unscrew the fuse drawer.
Figure 29. The fuse drawer on the back of the T100 thermal cycler.
2. Pull out the fuse drawer and remove each fuse.
3. If a fuse is damaged, replace it with the correct fuse, and close the drawer.
A bad fuse shows a break or burned spot in the metal. A good fuse has intact metal.
