When you say "it's propane" is there any chance the oven has a natural gas spud or gas feed orifice? Or that the gas valve is for NG and not LP? If it is wrong you could be in for a nasty surprise. I would shut that oven down and not use it til you can get a gas tech out to check every facet of your range and LP system, including the regulator pressure in the feed line. Be careful here. Something wrong can lead to loss of life. Shut it down and get it checked before using it again.

Movavean,
We ordered propane, so I am assuming thats what we got.

I googled "bluestar jet engine". No response. Even searched
oven noise etc, on this forum. No real answers.

Trevor, are you out there?
Thanks

The link below describes the problem and the solution -- I assume it's the same problem. I've read around Bluestar and propane because it's one of the ranges in the running for me.

Here is a link that might be useful: noise

I think what you're hearing is normal. I have a BlueStar propane range and the oven makes a "jet engine" noise until it comes up to temperature and periodically thereafter as the oven maintains temperature. I have had my range for a year and half and haven't had any problems associated with the noise. After a while, you will get used to it.

I'm curious what you find out. I've got a 36" (propane) and love it. It's been very reliable. The only thing we had was a rattling convection fan that They sent me a kit to fix.

Mine does make the jet engine noise but has from day 1. I assumed that's just what happened. I've never had a big oven before and figured it takes a lot of power to heat up.

It also startles people who are in the room, which is fun. =>

I have read several posts where people claim to have this jet engine noise, but I do not hear it at all.

I have a brand new Bluestar 36" running on propane. It was converted from NG to LP by the dealer before delivery. I just went down and turned it on and I can hardly tell the oven burner is on it is so quiet. I read elsewhere that the noise may be intermittent. So far I have not experienced it. My gas dryer, on the other hand, roars every time the LP burner lights. I guess this is the sort of noise some people are hearing on their BS ovens?

Sounds like a jet engine in my kitchen 🙄🤯

Does anyone else's oven make a lot of banging and popping noises as it bakes? I was told by customer service this was normal, but it sure seems abnormally loud.
