Hi, this is Wayne from Sears PartsDirect. We’re going to talk today about preventing
and repairing arc and burn marks inside your microwave.
Some of the common causes are: Food spattered on the liner that is not cleaned
off. Incorrect rack usage during cooking.
Aluminum foil or metal getting too close to the side during cooking.
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.
First, order the correct paint for your microwave. Then follow these steps to touch up the affected
areas: 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.
Now here are some tips to help you prevent arcs and burns in the future.
Clean the cavity often. For stubborn residue, place 1 or 2 cups of
water in a microwave-safe cup. Bring that to a boil for 2 to 3 minutes. The steam will
soften the mess so that it’s easier to clean out.
Keep rack supports clean or they can start to melt
Cover food when cooking or reheating to avoid splatter.
Do not store the metal rack in the microwave and only place the rack in the microwave when
it will be used for Multi-level cooking. When using the rack, insert it correctly so
it doesn’t touch the sides or back of the microwave cavity and it’s mounted correctly
in all of the rack supports. Never place the rack on the floor of the microwave
Never use the metal rack when cooking popcorn. As the bag expands, it could push the rack
out of position and create arc or burn marks. Well I hope this video helped you out today.
