blockage or damage. If above checks are okay, but

 

 

 

 

pressure switch is still not closed, replace gas valve.

 

 

 

Air pressure switch

Check air switch terminals for supply voltage to

 

 

 

 

terminals NO2 and COM. If voltage is present on one

 

 

 

 

side only, check for air tube blockage or misalignment.

 

 

 

 

If these are okay, adjust air pressure switch or replace

 

 

 

 

if necessary.

 

 

 

Oven cavity hi-limit thermostat

Terminals are normally closed, opens at 660°F (350°C).

 

 

 

 

If open, reset and test oven for proper operation. If

 

 

 

 

thermostat will not hold for maximum oven temperature,

 

 

 

 

and oven is not exceeding control setting, check for

 

 

 

 

proper location of capillary bulb in its spring holder. If

 

 

 

 

above checks are okay, replace hi-limit thermostat.

 

 

 

Ignition control

Check for proper supply voltage to ignition control.

 

 

 

 

Check for proper voltage to the burner blower motor.

 

 

 

 

This can be checked at motor connecting plug

 

 

 

 

terminals 2 and 5. If voltage is present, proceed with

 

 

 

 

next step, if not, wait 30 seconds, push reset button

 

 

 

 

and try to restart. If this fails, check wires from

 

 

 

 

thermostat and burner blower motor to the ignition

 

 

 

 

control. If the above checks okay, replace ignition

 

 

 

 

control.

 

 

 

Burner blower motor

Check for supply voltage to motor. WITH POWER OFF:

 

 

 

 

Turn blower wheel to check for locked rotor. If supply

 

 

 

 

voltage is present at motor connecting plug terminals 2

 

 

 

 

and 5, and motor does not run, replace burner blower

 

 

 

 

motor.

 

 

 

Air pressure switch

Check for proper supply voltage switching from “NC” to

 

 

 

(burner blower)

“NO” on ignition control. Check for air pressure switch

 

 

 

 

adjustment, air tube blockage or misalignment. If these

 

 

 

 

adjustments fail, replace air pressure switch.

 

 

 

Spark generator

A pre-purge time of 30 to 60 seconds occurs after

 

 

 

 

burner blower motor starts. Check for supply voltage at

 

 

 

 

spark generator. If voltage is not present, check reset

 

 

 

 

button for ignition control. If voltage is still not present,

 

 

 

 

replace ignition control. If there is input voltage to the

 

 

 

 

spark generator, but there is no high voltage output,

 

 

 

 

replace the spark generator.

 

 

 

Igniter/sensor assembly

Check this assembly for visible damage. Replace as

 

 

 

 

needed. If there is no visible damage, check for voltage

 

 

 

 

supply to igniter/sensor assembly. If there is voltage

 

 

 

 

supplied to the igniter/sensor, but there is no spark,

 

 

 

 

replace igniter/sensor assembly.

 

 

 

Gas valve

Gas valve should open when proper supply voltage is

 

 

 

 

present. If there is no voltage present, check reset

 

 

 

 

button on ignition control, and all connections for

 

 

 

 

tightness. If there is still no voltage to gas valve,

 

 

 

 

replace the ignition control. If there is voltage to the gas

 

 

 

 

valve, check for gas pressure at the gas pressure tap

 

 

 

 

(located in the gas piping just prior to the burner). If

 

 

 

 

there is no gas pressure, replace the gas valve.

 

 

Flame will not stay on

Flame sensor

To check for flame sensor operation, connect a digital

 

 

 

 

multimeter (capable of measuring DC microamps)

 

 

 

 

between the flame sensor wire and terminal #1 on the

 

 

 

 

ignition control. Sensor current is to be 3 microamps,

 

 

 

 

minimum. If these readings are not achieved, replace

 

 

 

 

igniter/sensor assembly. Also check for any type of

 

 

 

 

damage to flame sensor wire and connections.

 

 

 

 

NOTE: The DC microamp test must be conducted with

 

 

 

 

the oven in low flame (bypass) operation.
