Replacing Fuses
Fuses on the C1000 Touch 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 C1000 Touch 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 in to 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 resources.” on page ii).
Finally, check that the fuses are intact. The C1000 Touch thermal cycler runs with two fuses
(Figure 33). To remove and check the fuses, follow these steps:
WARNING! To prevent electrical shock, always turn off and unplug the instrument
from an electrical outlet before checking the fuses.
1. Use a small coin to open the fuse drawer.
Figure 33. The fuse drawer on the back of the C1000 Touch thermal cycler.
2. Pull out the fuse drawer and remove each fuse.
3. If a fuse is damaged, replace it with a new fuse, and close the drawer.
A bad fuse shows a break or burned spot in the metal. A good fuse has intact metal.
