7.1.4. Replacing the Fuse(s)
The unit is supplied with a dual line fuse holder. In the unlikely event the main
power line fuse(s) has blown, it can be replaced. The fact that the main fuse may
have been blown is evidenced by the lack of any indicator lights on the front of
the control unit. (A failed internal power supply may cause similar symptoms but
there is no field fix possible for that condition.)
To replace the fuse(s):
1. Turn off the unit and disconnect from the power source.
2. Remove the fuse holder by prying up as shown in
Figure 7-11
.

3. Be sure to replace fuse(s) with the same rating: T-type 4.0A, 250V.
