4.5 Fuses

Replace the ventilator fuses (Figure 4-5, Figure 4-6) as required. See
Chapter 5 for component removal/installation and voltage selection
instructions.
• Replace both fuses at the same time.
• Reinstall the fuse drawers into the power entry module with arrows on
the front of the drawers pointing to the right.

NOTE: The original 3.5-A fuse (100-120 VAC) is now obsolete, and has
been replaced with 4.0-A fuse (P/N 104196), starting with units
built s/n 126396 and above. Because the circulation fan muffler is
labeled with the fuse rating, a replacement circulation fan muffler
(P/N 1041193) is labeled with the 4.0 A rating.
When replacing the 100-120 V, 4.0 A fuse and/or the circulation
fan muffler, verify that the fuses and muffler have the same fuse
value. If the value of the fuses and the muffler labeling do not
match, install both the 100-120 V, 4.0 A fuse (P/N 104196) and
the 4.0 A circulation fan muffler (P/N 1041193).
