Problem
Potential reason
Potential solution
Sparking
1. Burnt on food debris
Burnt on food debris in the microwave, on
the waveguide and the behind the
waveguide can cause the microwave to
‘spark’. This is because burnt on debris
can be focused on by the microwaves and
spark.
2. Metal or foil
No metal or foil should be put inside a
microwave as it can cause ‘sparking’
which can damage the microwave.
3. Pressure build up in
food
Food with none porous skins (potatoes for
example), must be pierced to allow steam
to escape. As the build up of pressure can
cause food to burst and create a ‘fire
hazard‘.
Heat spots
Operated empty or with
no moisture
Microwaves cannot be run empty,
microwaves need moisture to operate
correctly.
If microwaves are operated empty or are
used to heat up plates (this is not
permitted), the microwaves can focus on a
single point inside the microwave. This can
cause a heat spot, which can cause the
area to become deformed, warped or start
to melt.
If microwaves are operated empty or to
heat up foreign objects this will void the
warranty.
