My name is Billy.
Is this the hot surface glow ignition model?
just a moment while I pull the specs
thank you for waiting.
At this point have you cleaned the flame sense rod yet?
but you did steel wool it?..the glaze is clear not visible as build up
and if so...is the flame reaching the sensor within 3 seconds and actually engulfing the sensor?..or is not reaching the rod in time?
what does the yellow light do when flame ignites?
see chart regarding lights HERE
is this natural gas or propane?
Ok I will try again....basically the yellow light reacts to if it sense flame. If the light is a solid yellow it reads good flame...if dim or flicker it reads poor. Obviously if no flame makes it across the flame light will not light. The green blinking is a soft lockout for failed ignition.
Are the burners rusty?
Have you swapped and/or cleaned?
Has the gas utility had pressure checked since you purchased?
you have few choices...
If the gas is not crossing the burners:
Burner crossover channels are not clean
The gas pressure is too low
This is not possible just from gas supply but the regulator in gas valve also.
Can you post a pic of the gas valve using the attach files link?
Sorry about the glitches...what is the make model of the valve
the valve I need is the big blocky item the gas pipe goes into before it goes to burners
I hope this works....is this similar to your valve
remove the screw cover and under you will see a white plastic regular screwdriver fitting. Keep count of the rotations and turn clockwise 2 full turns. Try furnace again....just keep track of rotations so we know our start point.
ok turn clockwise to bottom out.
Then try. It is normal to have 6 full turns adjustment range on these.
Ok, it is now time to check flame rod micoramps and furnace ground.
could be a ground issue
bad ignition control
poor connection of flame sensor
Do you have a meter capable of reading microamps?
sure, just wait to respond until ready.
ok, now to check microamps..
set meter to Ua.....unplug sensor wire from board and insert meter lead into the wire end connector...put other meter lead to terminal where sensor plugged into.
you can measure briefly the flame sense reading during 3 seconds of operation...and if needed holding a flame, lighter etc on the sensor and taking reading.
See Here for tips
that should suffice for now.
Do you get any ac volt reading at all if you measure neutral to ground?
