Norcold 1200 colder on electric than propane UPDATE

[kmb1966]

Been testing the Norcold 1200 for several weeks. Several thermometers all reading the same.
Set on 7, Electric mode each morning 35/36 degrees.
switch to propane
Set on 7, propane mode each morning 43/44 degrees.
Moving to 8,9 makes no improvement.
Switch back to electric, on 7, consistently on 35/36 degrees.

obviously something wrong with propane mode.
Replace burner?

Thank you for these suggestions.
Since it is a new cooling unit, I am assuming that the flue/baffle and flue cap are all good. I know the flu cap is there (appears to be welded on the Amish unit).
I ordered a new burner and will install. I am not sure how to test the LP pressure

You are qualified to work at Camping World:B Your problem is LP PRESSURE! Replacing parts is NOT the fix. It is at CW. Doug

Update....
Doug is going to be right (again) on this. I changed the orifice and burner. Flame looks textbook correct. But still does not cool as well in propane mode as it does electric. 35 in electric, 42 in propane. (7 degree difference)
Having the LP pressure tested next.

How do I test LP Gas pressure?
Since my burner is 16 years old, maybe it wasn't a total waste of $ to buy another burner. 🙂

You have to use a LP Manometer. It should be at 11.5 inches Water Column. The burner is Steel. I have not had to replace a burner in years. Just a good cleaning and verify the orifice is clean and open. Doug

Try blowing out the burner with compressed air.

What color is the flame?

The cooling unit is new (Amish cooling unit)
But the burner age is unknown to me. Might be the original burner. I can see a blue flame.
