Sudden drop in LPG pressure/ flame height

[Boatguy30]

Tonight we had 2 burners and the oven going. Then the oven went out. Happens when bottle is almost empty.

Turned out the bottle was 1/2 full but currently using low psi butane. Adjusted the regulator a few months ago.

Has anyone had a line or regulator clog? Intitially flame came back up after switching to another bottle at 45 psi, but then back to just one very low flame.

We had this happen recently. Thought it was the solenoid. Nope. Turned out it was the regulator.

I have had a regulator freeze & stick-with resultant low flow. It happened when drawing a large qty of propane. Cured by turning tank valve off & tapping on regulator as it warmed.
I replaced the reg.soon after./ Len
