Oven issue
 

I have a weird issue with my oven. Whenever it reaches the target
thermostat number (400 degrees or whatever) , it makes a loud boom sound.
Not terribly loud....but not quiet either. Its usually at the moment when
the gas turns off. (when the thermostat reaches the desired amount) This
sound only happens the first time the over reaches the thermostat
amount....all other instances of it going above and below the thermostat
number , it doesnt make that sound. Only the initial time. The oven uses
propane by the way.

Any ideas ?

Used to be called 'oil canning', after the flexible bottomed oil cans
that allowed one to pump oil from the spout. Your oven has a panel
that expands in the center beyond what the edge does. When the
resulting stress is relieved, the noise occurs. Probably not harmful,
might even quit doing it after some time.

Thanks Joe. Yeah i've noticed sometimes its barely audible. While other
times its pretty loud. I never knew about this Oil stuff. oil cans ?
From what im able to translate it seems like its just metal constricting
from the heat.

In your case metal is expanding from heat and tryng to go from flat to
a convex or concave shape because of its confinement. the oil
cans, they were made with a convex bottom which could be pressed into
a concave shape with finger pressure, thus changing the internal
volume and acting like a pump when inverted . Very handy for squirting
oil into the babbit bearings on your great-grandad's Buick water pump
or windmill pump jack. G
