Main fan If not operating, refer to “Oven fan will not run”. Centrifugal switch of main fan

motor

Check for 120VAC at wire #5 (input to centrifugal

switch, located at 6-pin connector in raceway near

the main fan motor) to neutral. If no voltage is

present, trace wiring back to the main power

switch. If voltage is present, check for 120VAC at

wire #22 (output of centrifugal switch) to neutral. If

no voltage is present at #22, and the motor is

running, replace the main fan motor. Hi-limit thermostat,

oven cavity

Terminals are normally closed. If open, reset

thermostat and retest. If thermostat will not hold

for maximum oven temperature, and oven is not

exceeding temperature setting, check for proper

location of capillary bulb in its spring holder. If the

capillary checks okay, replace the hi-limit

thermostat. Burner blower motor Check for 120VAC supplied to burner blower

motor at wire #13 to neutral. If no voltage is

present, trace wiring back to the main power

switch. If voltage is present, and the motor is not

running, check for opens, shorts or grounds.

WITH POWER OFF: Turn motor to check for

locked rotor. Burner transformer Check for 120VAC supplied to the primary of the

burner transformer. If no voltage is present, trace

wiring back to the oven cavity hi-limit thermostat.

If voltage is present, check for 24VAC at

transformer secondary. If there is primary voltage

but no secondary voltage, replace burner

transformer. Centrifugal switch of burner

blower motor

Check for 24VAC at motor connector, wire #13 to

neutral. If voltage is not present, trace wiring back

to transformer. If voltage is present, check for

voltage at wire #14 to neutral. If no voltage is

present at wire #14, and motor is running, replace

burner blower motor. Ignition control Check for 24VAC at ignition control terminals

marked “24V”, if no voltage is present, trace wiring

back to centrifugal switch. Check for 120VAC to

ignition control at terminal “L1” to neutral. If no

voltage is present, trace wiring back to main

power switch. When 24VAC is supplied to the

ignition control, the ignition control switches

120VAC to the hot surface igniter If 24VAC and

120VAC are supplied to ignition control, but there

is no voltage at the hot surface igniter, replace the

ignition control. Hot surface igniter If 120VAC is present at hot surface igniter

terminals, visually check to see that the igniter is

heating (igniter may be viewed through the port in

the end of burner tube). The igniter should glow

bright red. If the igniter does not heat, replace the

hot surface igniter. Ignition control After 45 seconds of hot surface igniter pre-heat,

the ignition control will switch 23VAC to the gas

control valves. Check for 24VAC output from

ignition control across terminals marked “valve”

and “valve gnd”. If no voltage is present, replace

ignition control. Gas control valves When 24VAC is supplied to the gas control

Impinger II – Advantage Digital Service Manual - Domestic

valves, the valve should open. Check for gas

pressure at the manifold tap located just before

the burner. If there is no pressure, check the

incoming gas supply to be sure all manual valves

are open and flexible gas hose is properly

connected. If gas is present, and the gas control

valve is energized, but there is no gas pressure at

the burner manifold, replace the gas control

valves. Flame will not stay lit Hot surface igniter Six seconds after the gas valve opens, ignition

must occur. If flame is not detected, the ignition

control will shut off and lock out. To reset the

ignition control, turn off the power switch for 45

seconds, then turn the switch on to re-try ignition.

The ignition control requires a minimum of 0.8 DC

microamps to prove flame. To check flame

sensing operation, connect a digital multimeter

(capable of measuring DC microamps) between

the “ground” terminal on ignition control and the

ground lead.

NOTE: This is a current measurement and the

meter must be connected in series

If these readings are not achieved, replace hot

surface igniter.

NOTE: The DC microamp test must be conducted

with the oven in low flame (bypass) operation. Set

the temperature control to the lowest setting. Power supply If there is sufficient microamp current, but the

flame will not stay lit, check for proper polarity of

the 120VAC power supply. Ignition control If there is sufficient microamp current, and the

120VAC polarity is correct, but the flame will not

stay lit, replace the ignition control.

NOTE: Check for proper ground connection on

ignition control. NOTE: Flame should be on at

this time

Low flame is on, but no main flame

Control transformer Check for 120VAC supply to the primary of the

control transformer. If no voltage is present, trace

wiring back to the main power switch. If voltage is

present, check for 24VAC at the transformer

secondary. If there is primary voltage, but no

secondary voltage, replace the control

transformer. Oven control Check for 24VAC supply to control. If no voltage is

present, trace wiring back to control transformer. If

24VAC is present, check for a read-out on the

display. If there is 24VAC supplied, but there is no

read-out on the control display, replace the oven

control.

If there is a read-out on the control, set the control

to maximum temperature (see installation

operations manual for temperature adjustment).

With the control set at maximum temperature,

check for 120VAC at the temperature regulation

valve. If there is voltage at the temperature

regulation valve, proceed to “Temperature

regulation valve” for next check. If there is no

voltage at the temperature regulation valve, trace

wiring back to the oven control. If there is no

Impinger II – Advantage Digital Service Manual - Domestic

voltage output at the oven control, check the read-

out on the control. If the control reads “PROBE

FAIL”, this indicates that the thermocouple has

failed or become disconnected from the oven

control. Thermocouple Check to be sure that the thermocouple is

securely connected to the oven control. If the

thermocouple is connected to the oven control,

and the control indicates “PROBE FAIL”,

disconnect the thermocouple from the oven

control and measure the resistance of the

thermocouple. The thermocouple should read

approx. 11Ω. If these readings are not achieved,

replace the thermocouple. If these readings are

correct, proceed. Oven control If the thermocouple checks good, but the oven

control display indicates that there is a

thermocouple failure, replace the oven control. If

the oven control indicates a temperature reading

but the oven will not heat, proceed. Thermocouple WITH POWER ON AND THERMOCOUPLE

ATTACHED TO THE OVEN CONTROL: Measure

the DC millivolt output of the thermocouple. Refer

to the thermocouple chart (located in the

“Removal” section of the manual) for proper

millivolt readings. If these readings are not

achieved, replace thermocouple. Oven control If the thermocouple checks good, but there is no

120VAC output to the temperature regulation

valve, replace the oven control. If there is 120VAC

output to the temperature regulation valve,

proceed. Temperature regulation valve Check for 120VAC supplied to temperature

regulation valve. If voltage is present, listen for

valve to open and close. Also check for opens or

shorts in the operating coil. Replace temperature

regulation valve as needed. Intermittent heating Thermal/overload of main fan

and burner blower motors

The main fan motor and burner blower motor are

equipped with internal thermal protection and will

cease to operate if overheating occurs. As the

motors overheat and then cool, this will cause the

heating system to cycle on and off intermittently.

Improper ventilation or lack of preventive

maintenance may cause this problem. Also, most

of the problems listed under “Oven will not heat”

can cause intermittent failure. Conveyor will not run Power supply Check for incoming voltage at line 1 to neutral.

There should be a reading of 120VAC. If not

present, check circuit breakers. Fuse, 10 Amp Check, replace if necessary. Fuse holder Check, replace if necessary. Hi-limit thermostat, control box Check for voltage on both sides of switch.

Terminals are normally closed. If open, reset and

test oven for proper operation. If thermostat will

not hold, and control box temperature is not

exceeding 140°F (60°C), replace thermostat. Power switch Check continuity between switch terminals.

Replace switch as needed. Control transformer Check for 120 VAC supply to the primary of the

control transformer. If no voltage is present, trace
