Official LG microwave/hood combo parts

Repairing arc burn marks inside the cavity of your LG microwave hood combo

• For microwaves that are not stainless steel on the inside, you can repair arc marks up to the size of a quarter using this touch-up paint, but only if the marks appear on the inside walls, the floor, or the ceiling. Don't attempt repairs on the outer frame, or the door. Any repairs to the door or frame could affect the shielding and cause radiation leaks. And don’t attempt repairs on burn marks larger than a quarter, as that could be a sign of a more serious problem and should be checked out by a service technician. Also, don't use this repair on microwaves with a stainless steel the inside, because the paint won’t stick.
• Clean the area using soapy water and dry the spot thoroughly.
• Sand the burnt spot down to bare metal using a fine grit sand paper. Wipe the area clean to remove any residue.
• Apply a thin coat of microwave cavity touch up paint. Wait for 5 minutes to allow the first coat of paint to dry. Reapply a second coat of microwave cavity touch-up paint. Be sure to wait 24 hours for the paint to dry before using your microwave.

• Door handle. The door handle allows you to open the microwave door to pull you food after when it's cooked. A service technician should replace the microwave door handle because door shielding is disturbed during the repair process and the door should be properly tested for microwave radiation leakage before the microwave is returned to service.
• Circulation fan motor. The circulation fan motor drive the exhaust fan blades to remove smoke and cooking odors from the kitchen.
• Vent grill. The vent grill covers and protect the opening at the top of the microwave cabinet above the door.
• Exhaust vent damper. The exhaust vent damper allows exhaust air out but prevents air from flowing back into the kitchen from the exhaust duct system when the fan is off.
