Troubleshooting Bake
Bake element not heating
Check house
outlet : L1 to L2
240 Vac ?
Refer to
electrician
Remove control panel, on
main PCB locate CN1
connector and remove
connector from PCB. Using a
volt / ohm meter check
resistances across two Yellow
wires of CN1.
Is it 3 Ω resistances or less ?
Check hi limit
thermostat
on back of
the range.
Reset and
retry
NO
NO
YES
YES
At main PCB locate A5 black
wire(L1) and A3 red wire
(L2) measure across the
two terminals and verify
voltage.
Is 240V present ?
Back track
voltage loss
on either L1 or
L2 between
terminal block
and PCB.
NO
Set control to Bake and start
oven, Locate A4 purple wire
and A2 Brown wire. Measure
across two terminals and
verify voltage
Is 240Vac present ?
YES
YES
YES
NO
If there is
not 240V
out put from
between A4
to A2
replace main
PCB
Next Colum
NO
Next Colum
Check for
loose terminal
connection
and retest
YES
Remove power cord from
wall. Remove A4 purple and
A2 Brown wire from PCB.
Measure resistances between
the two wires. Is the
resistances around 17 to 18 Ω
Remove
wire lead from bake element,
measure resistances across
bake element.
Is element 17 to 18 Ω ?
NO
Replace
element
NO
Check for open wires between
element and PCB, A4 to HD1 and
A2 to HD2. Repair or replaces as
needed.
YES
