TROUBLESHOOTING GUIDE 1000 & 1200 SERIES / ELECTRIC OVENS

SYMPTOM

POSSIBLE CAUSE

EVALUATION

Oven fan will not run

Incoming Power Supply

Check breakers/Reset if required/ Call Power Co. if

NOTE:

 

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

 

Fuse Holder

Check and/or Replace

 

Fan Switch

Check continuity between switch terminals.

 

Main Relay

Check continuity to 120 VAC coil. Check for power

 

 

to the relay coil (120 VAC). Check for 208/220/240

 

 

VAC to relay terminals. Visually check for contact

 

 

pull-in

 

Fan Motor

Check for opens, shorts, or grounds.WITH POWER

 

 

OFF: Turn Fan Blade to check for locked rotor.

 

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 cool down

 

 

thermostat pre-heated, check for continuity. If

 

 

switch is open, replace.

No control box cooling

Main Fan Relay

Check for power to main fan relay. Visually check

 

 

for contact pull in.

 

Axial Cooling Fan

WITH POWER OFF: turn the fan blade to check for

 

 

locked rotor. Check for power (120 VAC) to cooling

 

 

fan. If 120 VAC is present at the fan motor and the

 

 

fan does not run, replace fan assembly.

Oven will not heat

Main Oven Fan

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

 

 

"Oven fan will not run."

 

Heat Switch

Check for continuity between switch terminals with

 

 

switch on. Replace if defective.

 

Air Pressure Switch

Check for 120 VAC on both sides of switch. If

 

 

voltage present on one side only, check for air tube

 

 

blockage, adjust air switch. If above fails, replace

 

 

air pressure switch.

 

Hi Limit Thermostat

Terminals are normally closed. If open, reset and

 

 

test oven for proper operation. If thermostat will not

 

 

hold for maximum oven temperature, and oven is

 

 

not exceeding temperature dial setting, replace

NOTE:

 

thermostat (rated at 190°F).

Hi Limit Thermostat

Terminals are normally closed. If open, reset and

 

(Model 1032)

test oven for proper operation. If thermostat will not

 

 

hold for maximum oven temperature, and oven is

 

 

not exceeding temperature dial setting. Replace the

 

 

thermostat. Check for proper location of sensing

 

 

bulb in its spring holder. If hi-limit is still tripping,

 

 

replace (rated for 368°C).

 

3 Amp Temperature Control

Check and/or Replace

 

Fuse

 

 

Fuseholder

Check and/or replace.
