P- 1.2.2 FUSE(S) “OL” OR MORE THAN 1Ω / TROUBLESHOOT BAD FUSES
a) Replace the bad 6.3 Amp fuse(s) with the new* ‘slow blow’ fuses approved in 2016. Call Technical
Servces (1-800-227-2572), if necessary, to ENSURE you have the new fuses i.e. correct part number!
* NOTE! The ‘slow blow’ fuses should remedy the majority of fuse problems!
b)
Plug the machine in!
c) Push and hold the Power button for two (2) seconds. Does the machine turn on now (fan running)?
Yes Machine turns on! Problem solved. The fuse(s) were bad.
No Does NOT turn on! See parts a THROUGH d below:
a) CAUTION! To prevent damage, unplug the machine.
b) Measure resistance (Ω) across the fuses again. If one or both are bad then one of the
diodes inside Main Bridge Rectifier (BR1)
1
may be bad and destroying the fuse(s).
1
To LOCATE BR1 refer to Figure 132 (page 710).
c) Diode check
2
or replace the Main Bridge Rectifier (BR1).

NOTE: All Bridge Rectifier wires must be unplugged before performing a diode
check. The wires are position sensitive. RECORD where they plug into
BEFORE unplugging to prevent damage!
d) If the Bridge Rectifier checks good, or was previously replaced and the fuse(s) continue to
‘blow’ immediately proceed to
page 708, procedure number P- 4.0.0.
