Hi, everyone! I just found your site while trying to find help for my problem. I'm so happy to have found you! I'm sure I'll be here regularly from now on, but meanwhile.... Help! We have a Heartland Oval, about 6 years old now. It has the 6 lids on top, water reservoir, warming oven.. it's great. My DH usually takes care of cleaning & oiling it, but he's in Afghanistan this winter, so I've been doing it. I hated having to tell him what I'd done to it.... See, the day before Thanksgiving I wanted to get her cleaned up real good to get her ready for the hard work of cooking the holiday feast. She had a just a teeny bit of rust starting so I got the bright idea of using Naval Jelly to clean off the rust. (Remember, this is not normally my job, I'm just a temp in the woodstove maintenance field!!). I applied it and then rubbed it off with a paper towel... looked great! I then oiled the cooktop afterward, and since more is always better, I really slopped the ol' vegetable oil on there. Then I rubbed it in good. Naturally some got down in by the lids, but I didn't worry about it because I figured it would just add more rust-prohibiting to the edges of the lids & lid holes. Normally when I oil her, I light a fire afterward to heat up the surface. This time I didn't get the fire lit till the next morning. It was a couple of days after Thanksgiving that I discovered my problem (not the mental one, the woodstove one): One of my lids is stuck. It's the big one that sits right in front of the oven damper. I can get a screw driver into the crack and pry it up just a teeny bit, but it won't come up. I wrote to Heartland for advise and the nice lady there suggested tapping at it to loosen it. No luck. When I wrote to DH and told him about the problem (with much chagrin and many apologies!) he forgave me right away and suggested that I go online to search for help. My sweetie! The Heartland lady had also suggested that creosote build-up might be part of the problem. I was thinking about rubbing some spray creosote remover into the crack around the edge of the lid, but I wanted to get a second (or several!) opinion before I do. When I try to pry the lid up with the screw driver, it only just budges a bit. I'm afraid to apply too much pressure for fear of snapping the screw driver off. Oh, did I mention that I broke the lid lifter? Yeah, I had it in position in the lid and was pushing down on it with a wrench. It snapped. The lid lifter, not the wrench. I nearly snapped myself, because I skinned my knuckles in the process (the cat will tell you, I said some very rude things). I also had an idea of getting the cooktop warm (not hot!), filling up my cast iron dutch oven with ice water and placing it on the stuck lid. Y'know, try to cause a contration due to cold? Has anyone else done something stupid like this? Was it even my fault? I mean, was it the Naval Jelly or the oil? Or is a creosote issue (okay, that would be my fault too because I'm supposed to not let that build up). What can I do? If it wasn't the lid in front of the oven damper I wouldn't worry about it so much, but I need to get at that thing to keep it clean & slidey. Sorry to have written a book, but I'm stuck. I've called the local stove dealer and they said "Gee, I dunno... we don't sell many cookstoves". Even the dealer who sold us the stove was no help at all, except that they would be happy to install a new cook surface for us... for about $1000 including labor. Sigh. I guess I've exposed myself as a twit right from the very first post on this site. Oh well. It's out of the way, so I won't have to try to keep it a secret!
