BAKE
Done
Does the Bake
cycle function
properly?
Does the spark
continue after a
flame is present?
Does the Bake
burner establish
a flame and then
turn off?
Is 120 VAC
present from
J1-4 to J1-6?
Is 120 VAC
present from
J1-4 to J1-7?
Turn the ERC off.
Test the distribution valve
for continuity at J1-1 and J1-2,
then J1-2 and J1-3. Are
both resistances
216 Ω ±30?
Connect a DC voltmeter
to J1-1 (+) and J1-2 (–).
Wait 40 seconds, then start a Bake
cycle. 6 seconds later, does
the meter indicate
8 to 18 VDC?
Check the polarity of
the supply voltage. Even
if no ground is connected,
the DSI control will not be
able to sense the presence
of a flame at the igniter if
the polarity is reversed.
Diagnose the main
wiring harness and/or
the electronic oven
control (ERC).
Diagnose the ERC.
The DSI control will lockout
if a call for Bake & Broil
exists simultaneously.
Measure the resistance at
the distribution valve. If different
than measured at the DSI control,
diagnose the wiring harness.
If resistances are the same as
measured at the DSI control,
replace the valve.
If the voltage is higher than
18 VDC, check the main wiring
harness for bad connections.
If okay, replace the
distribution valve.

Does spark
occur at the Broil igniter
but not the Bake?
Does spark
occur at the igniter?
Check the igniter for cracks in the
ceramics. If cracks are found, replace
the igniter. Diagnose the Bake igniter
wiring harness. If okay, replace the control.
The igniter position is
out of tolerance for the
proper ignition. Replace
the igniter and burner.
Check the igniter for
continuity. If not okay,
replace the igniter. If
the supply polarity is
correct, check the Bake
ignition wire for a loose
connection. If okay,
replace the DSI control.
