Turn “ON” for 5 minute test.
Hold probe perpendicular to surface being
tested. Scan surfaces at the rate of one inch per
second. Scan entire perimeter of door, control
panel, viewing surface of door window, and
exhaust vents.
Maximum leakage is 4 MW/CM2.
Record data on service invoice and microwave
leakage report.
Note:
Maximum allowable leakage is 5 MW/CM2. Four
MW/CM2 is used to allow for measurement and
meter accuracy.
Inform the manufacturer of any oven found to
have emission in excess of 5 MW/CM2. Make
repairs to bring the unit into compliance at
no cost to owner and try to determine cause.
Instruct owner not to use oven until it has been
brought into compliance.

Microwave Leak Test
Proof Feature
To test the performance of the proof feature, press
the WARM/PROOF pad, then turn the dial to PROOF
BREAD and press the dial to start. The following will
occur:
• The convection fan and interior lamp come on
immediately, and stay on.
• There is an immediate start-up burst (about 1.5
second duration at 75°F ambient) of heat from
the convection heater.
• The convection fan and interior lamp continue
to operate and, if needed, the convection heater
will cycle on.
Note:
Oven proof temperatures range from 75-
95°F. At ambient temperatures above 75°F, heat
generated by the interior lamp may be suf
fi
cient to
maintain proof temperatures, and the heater may
not cycle again after start-up.
If an inoperative convection heater in the proof
mode is suspected:
1. Disconnect
power.
2. Remove the rear access cover.
3. Remove the thermistor from the convection
heater assembly.
4. Lower the thermistor temperature by placing a
chilled or frozen item against the thermistor.
5. Connect power and enter proof mode.
6. Check for approximately 120 VAC (12.3 Amps) at
the convection heater.
