Wood burning stove Door gasket.

What is the expected lifespan of a wood-burning stove door gasket?

Don't know "expected"; I get a couple years from mine. We burn daily for six months a year or so.

Do you have to load through the door? If so I'd think every year or 2. My stove loads through the top so I rarely open the doors but my top gasket takes a beating.

My pellet stove door gasket leaked right from the start. There is some sort of sleeve where the ends meet and it leaks right there.

3 seasons of over 5 months continuous burning and about 2 months of a fire or two a day (nearly 22 cords total) on the Drolet Legend 3 and I may "just" be seeing signs of replacement required. I have adjusted the door once in that time for a snugger fit, which was last fall. It will probably last one more season as a guess. Last night was the first night without a fire since fall. We will need a few more fires yet.

I have a spare gasket and silicone on hand...have had since the stove was new.

You can probably fix that with some minor ingenuity and some high heat silicone. Drolet splices their gasket at the bottom door centre, which becomes a tiny leak. This can easily be rectified with a wee bit of silicone covered by a wee piece of aluminum foil or aluminum duct tape over that joint. I actually prefer the foil, as it is more malleable and more leak proof. I have a tiny, tiny leak right now with the tape, which I didn't have with the foil. I replaced it last fall for no reason whatsoever, other than the tape is more robust. The key is to make the silicone and foil just a tiny bit proud of the door gasket, like about a mm or so. It will squish down when you close the door to cure the repair. The foil is only there to prevent the silicone from sticking to the door while curing. I just dreamt this up, but it works well in the case of my stoves.

I don't think i replaced my jotul 3 gasket more than 1 time in over 15 years of daily burning.
I'm on year 4 with the jotul F400 i got used.
I bet it's the original factory gasket, I have not replaced it. It is still in great condition.

Thanks I will try that. My only idea (which was not of any help) was to try and "pluck" it to make it proud, but it's like they used some sort of heat shrink and it's hiding all the fibers. I can't expand it.
Have you tried not closing it to cure? That way you could use the silicon buildout, which will crush when you close the door for burning? I guess you can't take a chance on too much pressure on the glass?
I had the stove shutdown as we were sunny and 20C here today. I took a picture. That was probably a weeks worth or maybe two as I have been only burning about 16 hours a day now.

With the OEM gasket I get about 3-4 yrs with the 4th year being 'iffy'.

That gasket should seal using the method I described. On the drolet's (my two anyway) the splice is in the bottom centre, so the foil overlay which I wrap from the inside to the underside of the doorframe cannot be seen from the outside unless you are laying underneath the door.

The drolet's glass is sealed by a separate self-adhesive gasket and a steel wrap that wraps both sides of the edge of the glass and the whole glass, gasket, and frame is held in place by clips around the perimeter.
