No automatic control

Incoming Power Supply

Check circuit breakers, reset if required. Call the

 

 

box cooling

 

Power Co. if needed.

 

 

 

Fuse Transformer

Check, replace if necessary.

 

 

 

Fuseholder

Check, replace if necessary.

 

 

 

Cooling Fan Thermostat

Check the cooling fan thermostat (Thermostat

 

 

 

 

closes at 120°F and opens at 100°F). With the

 

 

 

 

cooling fan thermostat pre-heated, check for

 

 

 

 

continuity. If switch is open, replace.

 

 

 

Cooling Fan

120 VAC should now be at this motor. If voltage is

 

 

 

 

present, check motor for shorts, opens, or grounds.

 

 

 

 

WITH POWER OFF: check for locked rotor.

 

 

Cooling fan continues

Cooling Fan Thermostat

Thermostat is normally open and may have closed

 

 

to run after 20 minute

 

if control box temperature is 120°F or above.

 

 

cool down

 

 

 

 

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 Main Oven Fan

Check to see that the fan switch is on. Check if

 

 

 

 

main oven fan is operating. If not, refer to "Oven

 

 

 

 

fan will not run."

 

 

 

Oven Start Relay

Check for contacts to close.

 

 

 

Burner Switch

Check for 220 VAC to neutral on both sides of

 

 

 

 

switch.

 

 

 

Air Pressure Switch

Check for 220 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.

 

 

 

Gas Pressure Switch

Check for 220 VAC to neutral on both sides of

 

 

 

 

switch. If voltage is present on one side of switch

 

 

 

 

only, check the following. Check for proper gas

 

 

 

 

pressure supply to gas valve.(Marked on oven spec

 

 

 

 

plate). Check for proper adjustment of gas pressure

 

 

 

 

switch. Should be set at 8.8 for Nat., 23 for L.P.

 

 

 

 

Check gas filter in gas valve for blockage or

 

 

 

 

damage. (See Adjustment Section for location). If

 

 

 

 

the above checks okay, but switch still not closed,

 

 

 

 

replace gas valve.

 

 

 

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, check for

 

 

 

 

proper location of capillary bulb in its spring holder.

 

 

 

 

If above checks okay, replace hi-limit thermostat.

 

 

 

Ignition Control

Check for 220 VAC supply to ignition control at pin

 

 

 

 

#1 and neutral. If voltage is not present, retrace

 

 

 

 

wiring back to hi-limit thermostat. Check for 220

 

 

 

 

VAC at pin #6 to neutral.(Power to burner motor). If

 

 

 

 

voltage is present, proceed. If no voltage is

 

 

 

 

present, wait 30 seconds and check reset button. If

 

 

 

 

above fails, replace ignition control.

 

 

 

Burner Blower Motor

Check for 220 VAC supply to burner blower motor.

 

 

 

 

WITH POWER OFF: turn blower wheel to check for

 

 

 

 

locked rotor. If 220 VAC is present and motor does

 

 

 

 

not run, replace motor.

 

 

 

Burner Blower Motor Air

Check for 220 VAC switching to pin "N.O." as the

 

 

 

Pressure Switch

air pressure switch closes. For Honeywell ignition

 

 

 

 

control only, connect a temporary jumper wire (for

 

 

 

 

testing purposes only) from pin "C" to pin "N.O." on

 

 

 

 

ignition control (to bypass air switch). Check for air

 

 

 

 

tube blockage or misalignment, adjust air pressure

 

 

 

 

switch. If the above fails, replace air pressure

 

 

 

 

switch.
