Fans
The fan on the 30-in. model cools the left and right
generator board heat sinks.
The 36-in. model utilizes 2 fans. The main fan cools
the right and center generator board heat sinks. An
additional fan cools the left side generator board
heat sink.
Fans change speed based on heat. At low settings
the fan may not operate. As heat increases, the
fan will come on and increase in speed as heat
increases. When the highest power level (Boost)
is selected (indicated by H on the display), the fan
automatically comes on.
A single wire harness is connected to each fan
motor. All fans are operated by 12 VDC motors.
Caution: To prevent damage to fragile fan locking
tabs, test fan before removing it from the module.
Note: When testing these fans:
• You cannot test with an ohmmeter.
• Fan can be run for a short period of time using
a 9-volt battery. Connect the negative (-) battery
terminal to the black wire. Connect the positive (+)
battery terminal to the white wire.
The fan for the 30-in. model and the main fan on the
36-in. model are attached to the module base with 5
tabs. On the 36-in. model the left side generator fan
is attached to the module base with 3 locking tabs.
It is necessary to remove the heat shield to access
the fans. (See Heat Shield.)
