7. Silicone Grease on Power Transistor/Diode Bridge
Outline
Apply the specified silicone grease to the heat generation part of a power transistor/diode bridge
when you replace an outdoor unit PCB. The silicone grease encourages the heat dissipation of a
power transistor/diode bridge.
Details
1. Wipe off the old silicone grease completely.
2. Apply the silicone 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 generation parts are firmly contacted to the radiation fin.
Note: Smoke emission may be caused by bad heat radiation when the silicone grease is not
appropriately applied.
OK: Evenly applied
NG: Not evenly applied
NG: Foreign matter is stuck.
