The center glass is heat-treated and has the
letters “HB” stamped in two places near one
of the edges.
If you are in doubt as to which glass is heat-
treated, use an ohmmeter to check it. To do
this, set the ohmmeter to the R X 1 scale and
touch the test probes to the glass. If the glass
is heat-treated, the meter will indicate a short
(0
Ω
). If the meter does not indicate a read-
ing (infinity), the glass is untreated.
After reinstalling the oven door, check
around the door for microwave radiation
leakage.
