1. Verify failure if not displayed, using CANCEL/OFF key. Press key for 5 seconds until
last error code is displayed
2. Disconnect power from oven for longer than 30 seconds.
3. Reapply power and observe for longer than 1 minute.
4. If failure remains, disconnect power, replace control, then go back to step 3. E1

Shorted key 1. Verify failure if not displayed, using CANCEL/OFF key.
2. Disconnect power.
3. If applicable, insure membrane tail seated in connector on back of control.
4. Reapply power and observe for longer than 1 minute.
5. If failure remains, disconnect power, replace control, then go back to step 4..

1. Measure sensor value (between connector pins) between 1000
Ω
@ 32
°
F and
2697
Ω
@ 900
°
F (approximately 1080
Ω
@ room temperature).
If measurement does not correlate to real temperature, disconnect power,
replace sensor and refer to steps 3-5.
Also measure from sensor connector to sensor casing for possible short.
2. Trace wires and connectors to sensor, from control, then from sensor back to
control. If all connections made and no wire damage, refer to step 3.
3. Disconnect power for longer than 30 seconds.
4. Reapply power and observe for longer than 1 minute.
5. If failure remains, disconnect power, replace control, then go back to step 4.

Door and latch
switches do not
agree 1. If door latched :
A) Disconnect power from unit.
B) Check wires and connectors from control to door switch, then from door
switch to control. If no damage to wires and all connectors okay, proceed to
step C.
C) Replace door switch.
D) Reapply power.
E) Press and hold any key down for 1 minute to clear -F5- failure code from memory.
-F2- will appear. Press CANCEL and observe for 1 minute to ensure operation
is correct.
2. If door not latched :
A) Disconnect power from unit.
B) Check wires and connectors from control to latch switch, then from latch switch
to control. If no damage to wires and all connectors okay, proceed to step C.
C) Repeat steps A) and B) for door switch.
3. Measure door switch (door open = switch open small low voltage terminals).
4. Measure latch switch (unlatch = switch open,
CAUTION - oven light contacts are
closed).
5. If corrections are made in any step, reconnect power to control. Press and hold any
key for 1 minute to clear -F- failure code from memory. -F2- will appear. Press
and observe for 1minute to ensure operation is correct.
6. If failure remains, disconnect power, replace control.

NOTES:
1. All diagnoses of this range must begin with normal
check of line voltage, blown fuses, and failed
components.
2. All units that have failed during the first few days of
use should be checked for loose connections or
miswiring.
3. All checks should be made with a meter having
a sensitivity of 20,000 ohms-per-volt or greater.
