Top Load Lid "Warped" FAILED Dollar Bill Test (Lopi Leyden)

I'm not real sure when the revisions took place, there have been at least 6. They box that the stove came in would have said what revision it was, do you happen to recall what revision it said? The dealer should be able to run the Serial number on it, that should tell you.
They are sending new front door hinges, mine were sagging from the start and rubbed when they were closed.

Do you monitor stovetop temps in any way? Just curious...we have a thermometer on the stovetop, and one on the stack, and we let temps dictate our damper and air settings.

I don't think that lid could or would warp even if you had overfired it. The lid just sits there, it's not bolted down, it's free to expand and contract as it pleases.
The red Leyden that I was trying out (as a replacement to the Brown one that wouldn't work correctly) went totally out of control half way through the burn. My stove top was reading at least 1,000, nothing warped or cracked. I'm sure you haven't had yours that hot.

After dealing with Lopi for almost 10 years, I never once had to wait for a rep to approve a warranty claim. If I had any questions I could call the factory or my distributor right then and there, maybe sent a picture and have my answer on warranty coverage. It's been five years, so things may have changed but it seems like the dealer is dragging their feet. I would do what begreen said and be a polite squeaky wheel.
