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.
