5. Silicon Grease on Power Transistor / Diode
Bridge
Outline
Apply the specified silicon grease to the heat radiation part of a power transistor / diode bridge
when you replace an outdoor unit PCB. The silicon grease encourages the heat radiation of a
power transistor / diode bridge.
Detail
1. Wipe off the old silicon grease completely.
2. Apply the silicon grease evenly. See the illustrations below for examples of application.
3. Tighten the screws of the power transistor / diode bridge.
4. Make sure that the heat radiation parts are firmly contacted to the radiation fin.
Note: Smoke emission may be caused by bad heat radiation when the silicon grease is not
appropriately applied.
OK: Evenly applied
NG: Not evenly applied
NG: Foreign matter is stuck.
