Check breakers/ Reset if required / Call Power Co.

 

NOTE:

 

if needed.

 

(Export Ovens)

For some export ovens, there is a control circuit

 

 

 

step-down transformer. This transformer steps

 

 

 

down supply voltage to 120 VAC. If main fan will

 

 

 

not run, the secondary of this transformer must be

 

 

 

checked for 120 VAC output. Check specific oven

 

 

 

model schematic for circuit location.

 

 

Oven Fan Fuse(s)

Check and/or Replace

Fan Switch

Check continuity between switch terminals.

 

 

Main Relay

Check continuity to 120 VAC coil. Check for power

 

 

 

to relay coil (120 VAC). Check for 208/240 VAC to

 

 

 

relay terminals. Visually check for contact pull-in.

Capacitor

Check for opens, shorts, or grounds.

 

No Main Fan Cool

Cool Down Thermostat

Check cool down thermostat (thermostat closes at

 

Down

 

160°F and opens at 140°F). Check for power (120

 

 

 

VAC) at cool down thermostat. With the cool down

 

 

 

thermostat pre-heated, check for continuity. If

 

 

 

switch is open, replace.

Cooling Fan Thermostat

Check cooling fan thermostat (thermostat closes at

 

 

 

120°F and opens at 100°F). With cooling fan

 

 

 

thermostat pre-heated, check for continuity. If

 

 

 

switch is open, replace.

Oven will not heat

Gas Supply

Check for adequate gas supply to oven.

 

 

Manual Gas Shut-off Valve

Check to see that manual shut-off valve is open.

 

 

Fan Switch

Check to see that fan switch is "on".

 

 

Main Oven Fan

Check if main oven fan is operating. If not, refer to

 

 

 

"Oven fan will not run". Page 20.

 

 

Burner Switch

Check for 120 VAC to neutral on both sides of

 

 

 

switch. If switch is closed and 120 VAC is present

 

 

 

on one side only, replace the switch.
