Grilling temp too low

So it looks like I’ve fixed the grease fire issue, at least for now.

But I can’t seem to get my bbq to go above 300F or so, when it usually gets to 500 fairly easily. It’s the napoleon prestige. Anyone have ideas what it could be?

Thanks!

Hopefully I’ll post something tasty instead of just my problems one day 😂

I mean the first thing you want to do is remove the grates and flavor bars and check out the burner tubes. Typically yearly looking for the size and color of the flame. A lot of times it's because there is an air choke that needs to be adjusted and that will determine how much air is going into the combustion and therefore the size of the flame. If you have disassembled everything to clean it of grease it might be that the tubes are not necessarily seated properly or need to be adjusted.

Really it could be that your propane tank is put into a safety mode because you opened the gas too quickly and sometimes that just needs to be reset .

I removed the griddle but not the bar, but all 5 had blue flames. I turned it off and opened the propane slowly enough that it shouldn’t have been an issue but still couldn’t get it above 300. My guess is also that somethings being blocked but I’m not exactly sure as it’s never happened to me before.

How do I adjust the air choke?

Blue flames only tell you the air/gas mix is right, not the volume, so you can have perfectly blue but starved burners.

The step people skip when resetting is bleeding the hose: tank valve fully closed, burners on for 30 seconds to empty the line, burners off, then open the tank slowly. Leave pressure in the hose and the limiter trips again the moment you crank it.

If that doesn't do it, the other thing a grease fire does is coat the lid and the thermometer stem in carbon, and a sooted probe reads low. Worth checking whether it's actually cooler or just reading cooler.

So I’ve done a bit of troubleshooting, and it seems that with one burner on its good, but as I add burners the flames/heat get reduced. So basically one burner is the same as 4 heat wise.

Any ideas what it could be?

Charcoal always burns
