Cooling Fan(s)

120 VAC should be at the motor. If voltage is present, check

 

 

 

motor for shorts, opens, or grounds. WITH POWER OFF:

 

 

 

check for locked rotor.

 

Oven will not heat

Gas Supply

Check for adequate gas supply and closed manual gas valves.

 

 

Also, check flexible gas line connection.

 

 

Main Fan

If not operating, refer to "Oven fan will not run".

 

 

 

 

 

NOTE: These ovens utilize 2 complete burner/temperature control systems. Each system will follow the same

 

troubleshooting sequence.

 

 

 

Centrifugal Switch of

Check for 120 VAC supplied to the centrifugal switch, if

 

 

Main Fan Motor

voltage is not present, trace the wiring back to the oven power

 

 

relay. Check for 120 VAC out of the centrifugal switch. If

 

 

 

voltage is supplied to the centrifugal switch, and motor is

 

 

 

running, but there is no voltage out of the centrifugal switch,

 

 

 

replace the fan motor.

 

 

 

(NOTE: See Schematic Diagram of proper wire numbers on

 

 

 

motors.)

 

 

Fuse, Burner 10A

Check, replace if necessary.

 

 

Fuse holder

Check, replace if necessary

 

 

Burner Blower Motor

Check for 120 VAC supply to the burner blower motor, if 120

 

 

 

VAC is present and motor does not turn, replace the motor.

 

 

Burner Transformer

Check for 120 VAC to primary of the 24 VAC burner

 

 

 

transformer. If voltage is not present, trace wiring back to the

 

 

 

fuse. If voltage is present, check for 24 VAC at the secondary,

 

 

if no secondary voltage is present, replace the transformer.

 

 

Centrifugal Switch of

Check for 24 VAC supply to the centrifugal switch of burner

 

 

Burner Blower Motor

blower motor (see Schematic for proper wire numbers). If no

 

 

 

voltage is present, trace wiring back to the transformer. If

 

 

 

voltage is present, check for 24 VAC at the output of the

 

 

 

centrifugal switch. If there is no output, and the burner blower

 

 

motor is running, replace the burner blower motor.

 

 

Ignition Control

Check for 24 VAC supply to the ignition control at terminals

 

 

 

marked 24V and 24Vgnd. If voltage is not present, trace

 

 

 

wiring back to the centrifugal switch. Check for 120VAC

 

 

 

supply to the ignition control at terminals L1 and L2. If no

 

 

 

voltage is present, trace wiring back to fuse. If the above

 

 

 

checks are okay, proceed. The ignition control should switch

 

 

 

120VAC to the hot surface igniter, across the (2) terminals

 

 

 

marked HIS. If no voltage is present, replace the ignition

 

 

 

control.

 

 

Hot Surface Igniter

If 120 VAC is present at HSI terminals, visually check to see

 

 

(Located inside Burner

that the hot surface igniter is heating (igniter may be viewed

 

 

Assy)

through port glass in end of burner tube). The igniter should

 

 

 

glow bright red. Check all connections to be sure they are

 

 

 

tight. If the igniter does not heat, replace.

 

 

Ignition Control

After 45 seconds of hot surface igniter pre-heat, the ignition

 

 

 

control will switch 24 VAC to the gas control valves. Check for

 

 

24 VAC output from the ignition control, and across terminals

 

 

 

marked "valve" and "valve gnd". If no voltage is present,

 

 

 

replace the ignition control.

 

 

 

NOTE: The ignition control contains a safety lockout circuit. If

 

 

a flame is not detected within 6 seconds after the gas control

 

 

 

valve is energized, the ignition control will lockout. To reset,

 

 

 

turn the power switch "off", wait 45 seconds and switch the

 

 

 

system "on" to retry ignition.

 

 

Gas Control Valves

Check for 24 VAC supplied to the gas control valves. If

 

 

 

voltage is present, the valves should open. Check for gas

 

 

 

pressure at the pressure tap, located in the gas piping just

 

 

 

prior to the burner. If there is no gas pressure, and the voltage

 

 

is supplied to valves, check piping for obstructions. If there
