Pilot flame but no main

Flame Sensor

(There should be a visible pilot flame at this time.)

 

flame

 

To check for proper flame sensor operation,

 

 

 

connect a digital multimeter (capable of measuring

 

 

 

D. C. microamperes) in series between the flame

 

 

 

sensor wire (normally connected to terminal #4)

 

 

 

and terminal #4. NOTE: This is a current

 

 

 

measurement and the meter must be connected in

 

 

 

series. This procedure is for checking the pilot

 

 

 

flame only. Remove main valve wire (Red) from

 

 

 

terminal #3 on ignition control. With a visible pilot

 

 

 

flame, the current readings should be as follows:

 

 

 

Johnson G-65 control, 0.2 micro amp. D.C.

 

 

 

minimum/Johnson G-60 control, 0.7 micro amp.

 

 

 

D.C. minimum. If these values are not achieved,

 

 

 

replace flame sensor. Also check for any type of

 

 

 

damage to flame sensor wire and connections.

 

 

Ignition Control and Valve

If there is a pilot flame, and there is sufficient micro

 

 

Assembly

amp. current at terminal #4, check for 24 VAC

 

 

 

that the main valve (internal to valve assembly) has

 

 

 

opened. Connect a manometer to the manifold gas

 

 

 

pressure tap located on the back side of the ignition

 

 

 

control and valve assembly. If no gas is present,

 

 

 

replace ignition control and valve assembly.

 

For ovens with

Centrifugal Switch of Burner

Check for 24 VAC output from secondary of

 

Honeywell ignition

Blower Motor

transformer. If voltage is present, check for 24 VAC

 

control

 

at terminals marked "24V" and "24V gnd" on

 

 

 

Ignition Control. If the Burner Blower Motor is

 

 

 

running and there is no voltage at terminals 24V

 

 

 

and 24V gnd on the ignition control, replace the

 

 

 

Burner Blower Motor.

 

 

NOTE:

These Ignition Controls have a 30 second pre-

 

 

 

purge(Delay) and a 15 second lock-out time – The

 

 

 

Ignition Control will try for ignition for 15 seconds

 

 

 

and then shut-off. To Re-try for ignition, turn off

 

 

 

burner switch, wait 30 seconds and re-try ignition.

 

 

Ignition Control

Check for 24 VAC supply to ignition control at

 

 

 

terminals "24V" and "24V gnd". If voltage is

 

 

 

present, check for 24V at terminal "P.V. (Pilot

 

 

 

Valve) and "gnd". If voltage is not present, replace

 

 

 

Ignition Control. If the pilot valve is energized,

 

 

 

check to see that the high voltage ignitor circuit is

 

 

 

also energized. To check, disconnect the ignitor

 

 

 

lead from the ignition control. Place the terminal of

 

 

 

ignitor lead approximately 1/8" from terminal post

 

 

 

on Ignition Control. Spark should jump the 1/8"

 

 

 

gap. If no spark is present, replace ignition control.

 

No Pilot

 

If the ignition control is supplied with 24 VAC and

 

 

 

the pilot valve (in gas valve) and ignitor circuits

 

 

Pilot Shut-off Valve

If no pilot flame is visible, check to see that the pilot

 

 

 

shut-off valve is open(shut-off valve is located

 

 

 

between gas valve and burner).

 

 

Pilot Tube

Check for gas pressure at pilot tube. Disconnect

 

 

 

pilot tube at burner and connect manometer to pilot

 

 

 

tube. If no gas pressure is present, check for

 

 

 

blockage in pilot tube or pilot shut-off valve.

 

 

Pilot Orifice

If there is gas pressure at the pilot tube, check the

 

 

 

pilot orifice for obstructions. Replace as needed.

 

 

Burner Ignitor

Check the burner ignitor head for any obstructions,

 

 

 

also check for frayed or broken wire, any type of

 

 

 

damage to spark gap (.100 in. 2.5 mm) If there is

 

 

 

visible damage, replace ignitor assembly.
