Clean burn won't light

[dannyo]

I have a Cleanburn 1400. It has oil supply but no fire. I have changed the ignitor, checked electrodes. Done anyone have any advice?

Oil quality ?

Clean nozzle ?

Spark is good shooting past the nozzle ?

[dannyo]

Oil is good / nozzle is clean.
No spark what so ever.
I have cleaned how the oil laying in the bottom.
Do you know if there is thread or check list to go over the electric?
As I said I replaced the ignitor, electrodes look good, contact points on the ignitor are clean.
Is there sensor that detects excessive oil or mist?

Ok lets take it slow and simple.

No spark ? The easy way to check for spark is to lift the ignitor slowly while it is trying to fire to see if spark jumps to the electrodes.

Does the blue wire from the ignitor go to #7 on the wiring block or do you have an updated primary control to where 2 blue wires are wire nut together ?

[dannyo]

The blue wire is 7 and white is 1.

[ShopSpecialties]

Did you try lifting the ignitor to see if the spark would jump to electrodes ?

[dannyo]

I'll try that next.
Which wire should be hot?

[ShopSpecialties]

Blue

[dannyo]

Blue is 122 v when starting. I checked and adjusted the distance on the electrodes to nozzle and between.
Lifting ignitor there is an arc.
Should the white wire be 120v from ignitor when trying to fire?
Oil pressure is 3.25 psi / Air is 15 psi
it calls for 1.5 to 2.0 for oil psi.
Will the high oil pressure create this situation?

[ShopSpecialties]

The ignitor is producing spark so it is good. Next I would use an extendable inspection mirror through the inspection port to make sure the spark is not touching the nozzle or retention head. The spark should be shooting past the nozzle by at least a 1/2".

Was the heater working fine then you did something like fill the tank and it quit ?

[dannyo]

It was running, then quit and wouldn't restart.
I'll try the mirror. Thanks

What does the Cad Cell do?

[ShopSpecialties]

The cad cell is what trips the reset. If it does not get a good look at the flame it shuts it down.

[dannyo]

No spark apparent with mirror.
If I’m getting 120 v on blue ,spark on igniter to electrode, could the electrode be bad?

[ShopSpecialties]

Ok let's pull the burner and put it on the bench so we can get a better look at it.
On the electrode is any of the porcelain broken causing the spark to ground out ? To bench test for spark I like to power up the ignitor and combustion air motor. I use an extension cord with alligator clips. This way you will easily see what your spark is like and adjust/replace accordingly.
