What's the fridge flame supposed to look like ?

[SCVJeff]

Here's mine:


I don't think it should look like this. I haven't had it out yet but the visible top is clean and I just gave it a compressor blowout with no improvement.

[SCVJeff]

I get it, but as I've mentioned before, this probe is completely loose: see pix. Also notice the notch in the probe. It was dead Jim.... Chris has seen more than me so I don't know if this is salt erosion, heat, or both.

I still hear an occasional backfire when buttoned up, so I think I'll call the vendor and work on exchanging it. The original factory burner did this and I couldn't fix it

What's curious it pic #3. Dunno what the residue is from
POSITION 1


AND VERY LIGHT PRESSURE DOES THIS

As far as back firing goes, my money is still on Chris. The sparker also acts as a sensor (at least the ones I've worked on.)

I would also make sure the high intensity wire is clean on both ends and always has continuity with a meter when you twist that wire a little.

You're near salt water, the flue has metal in it, and a nice blue flame with an OEM burner has tips of yellow here and there. Thinking you got some very fine stuff falling into that flame when you're sending a stream of hot air up the flue.

For the shutting off, I would always do what Chris says first.

Yep, Salt will do that because it doesn't burn. Its already had a blowout when the burner was out. My primary concern once I can keep the thing lit is the occasional backfireing I see

its loose in its insulator I can move it anywhere I want with very slight pressure. Waiting for Package Man... Stby

Either thermocoupler, or loose electrical connection to thermocoupler?

[SCVJeff]

O-Boye ... 😞

My meter arrived today....
Pressure is dead on at 11", but now the thing is shutting off about 60sec into startup. It's been trying to respark itself so maybe the thermocouple is wonky. It's definitely loose in the bracket

[SCVJeff]

Yes, exact factory replacement. Waiting for the pressure gauge to show up to check that next

So this is a brand new burner tube, that was my question, if that is the case the slots in the tube regulate the propane flow. Is the tube the same as your old one? When I was trying to find a replacement for mine I noticed some tubes had an extra slot. If your tube is an exact replacement I would look more at the propane delivery system, (gas valve, orifice).

Get a wire brush and use one of the wires and clean the jet.
or replace the assembly.

If that doesn't help go down the line to the regulator.

Gjac: it's so random it's hard to know what really fixes it. I can but my finger over the home and adjust the flame but obviously not for long. I'll look at the pressure this weekend hopefully and see where it sits.

Randy: the burner chamber is press-fitted into the jet so I can't get anything in there. About all you can do with these is turn them upside down and blow them out. One thing I haven't done is pay attention to when it happens: right at power on when everything is cold, or after it warms up ?

Any way to look inside, or check for burrs, or chads?
