5.1.3 Check the fuse
Now that the interlock switches are no problem, you should go
ahead to check the fuse.
Remove the fuse and visually check it
- The fuse holder is located on the back of the unit. In some
units, you will need to remove the front panel to find the fuse
holder which is located on the bottom of the unit (Fig. 5.1.3-
1~2).
- With a flat screw driver, open the fuse holder cover and
remove the fuse. When opening the fuse holder cover (socket),
you need to push it down and gently rotate it until it is pulled
out.
- Taking out the fuse, visually check if it is damaged. If it is
damaged, replace it with 125Vac, 2A new fuse. A spare fuse
can be found in the operation manual plastic bag (See
6.11
REPLACE THE FUSE
) .
- If you are not sure if the fuse is blown out you can check with
ohmmeter.
Check the fuse with ohmmeter
- Set the ohmmeter in ohm range of 200 ohm or like the below
range (Fig. 5.1.3-3).
- Place the black and red from the ohmmeter to each end of the
fuse (Fig. 5.1.3-4).
- If the reading is "0.0x" the fuse is OK, if it reads "1" a new fuse
is needed (Fig. 5.3-4).
- Replace a new fuse and put back the front panel, check if you
hear the melody and the unit operates.
If the new fuse is blown out again you will need to prepare
yourself for some further electrical work to investigate the
causes, see next page.
