Cracked Gates

[Amateur Dave]

I’ve already had to replace these grates on the PB1100p twice. Now I’m needing to do it for a third time. Every time I go to 350 or higher, they crack in the middle. It does not matter if I warm it up slow, or just go straight to heat. This last time I did a low cook, then upped the heat for a sear. Heard the pop as it approached 350.

Anyone have a better idea for replacing these cast iron grates?

If it’s less than five years old it’s under warranty

Are you seeing fine cracks cleaning or chunks coming out?

Wow, that is so odd...thrice!

Both actual. The parts over the sear area come off in chunks

I wonder if it’s a design flaw with a grate that long and no middle reinforcement

The grill is over 5 yrs, but the greats don’t last 2

So PB says my warranty is out. Anyone know if a better grate set. Hate to buy ones from them just to replace them again?

Wow! Never used to sear function on my 1150. I've had it 400° plus and used a wet sponge scrubber many a times to clean.

I've only ever used the sear once, for about 5 minutes max. Maybe the flame diffuser is a good idea after all.

Heat Deflector/ Airgap Mod?

If I make a flame tamer would it be wise make the height adjustable? Or is there a good number that has been thrown out there to get the thing right?

Wow, that IS odd. I have an old 1100. Never had a grate issue. I have had to replace the heat plate. I swap the 3 grates around naturally just to make them get equal use, but never had to replace them. I wonder if your heat is actually higher than it reads. May be a controller issue? Just a thought.
