New Cornu Fe Stove - Oven door pops open

Hi,

I have a beautiful new Cornu Fe stove, which I love. It was hooked up just this week. The gas burners at the top are working well.

However, we are having a problem with the left-side oven. When we initially tempered it for an hour at 400 degrees, as recommended in the brochure, the oven door opened by itself, twice. We called Pennock Appliance, the people we bought it from, and they are not sure what might be going on.

We tried it again this morning, and once again, the oven door opens itself at about the time the oven reaches 400 degrees. We obviously cannot go on with the door popping open! The other oven is working well.

Can you advise me to what might be happening?

Many thanks,
Jacqueline Fuller

    It may be that the post of the catch is situated that it does not go in far enough into the roller catch when oven door is closed. Loosen the nut that holds the post (the part of the catch unit that is not on the door but is on the actual oven body). Pull the post outwards slightly, then retighten the nut to the post. It is that simple. Also, if the post does not fit correctly between the two catch double rollers when door is closed, you can carefully take a set of pliers and very slightly bend the post to fit(put pliers around whole post, not just tip of post). When you close the door in the future, do it carefully. Do not slam it. Do a two step process to close the door...Only close by holding the door knob and slowly close until contact and stop, then gently shut the door all the way catching the post.

I had the exact same issue with my Cornue Fe (only on the right hand side oven). The other symptom I noticed was that the door itself didn't close as smoothly as the left hand side oven.

Take a look at the alignment of the "post" sticking out from the oven relative to the spring loaded catch on the door. These need to be *very* well aligned vertically in order to keep the door closed as it heat cycles. You'll notice that the post has a depression at the end of it (furthest away from the door). The door catch has an upper and lower spring loaded roller that is supposed to "catch" on both sides of the depression. If you are misaligned vertically, then only one side of the catch will be applying sufficient force to the depression.

In my case, the post and the catch were misaligned by about 4-6mm. In fact, I noticed that repeated opening & closing of the door was actually causing some wear on the upper roller of the catch. To fix, I needed to raise the door, which was accomplished by adjusting the hinges.

I removed the door from the oven, which can be done by removing the screws on the hinges. The hinges consist of a bottom & top knob that slot into the door (similar to the way refrigerator hinges work). The hinges themselves are made of ~1/4" metal (could be stainless, but it's relatively soft stainless). I put the lower hinge in a vise (appropriate covering to prevent scratching) and *gently* bent it up to adjust the door upwards. Putting it back together required some help (the door is heavy), but after a bit of work it was all back. Thankfully the alignment was right the first time. This whole process took about 20 minutes.

In my case, I suspect that either the wife or kids had put too much weight on the door at some point and bent it out of alignment. The problematic door had about 4-6mm of "play" between the top and bottom hinges prior to my adjustment--the working door had zero "play". You might want to check to see if you have any such play before you do this work (you can either look at the hinge itself or simply lift up on the door at the hinge point to see if it moves). If you don't have this same play, but you do have misalignment, then you'll need to adjust both top and bottom hinges.

The other possiblity is that you might have a weak spring in the catch mechanism. You can check that by gently pushing a flat head screwdriver in between the two rollers and feeling for how much force is required to separate them.

Of course, you can also just call the La Cornue service folks and have them check it out.

I have a K/A kgst307 gas stove that was bought new as a natural gas unit. After 3 years, I moved to a house that had propane. NO PROBLEM because an LP conversions kit came with the stove. Used the stove on...


Although the natural gas orifices for the stove top burners were replaceable with propane orifices, many ovens/broilers orifices are simply adjustable using a 1/2" open end wrench to convert from one gas to another. Some brands are adjustable and some have to be changed out. It depends on the make and model. Do you have your owner's manual? It contains detailed info on converting your unit. I included a link below to choose from the list to download your manual. You'll need your exact model # listed on your stove. Pull out the bottom drawer and look at the data plate for the model # and then find it on the list for the correct manual. Douglas

My stove lights very slow with a low flame. Should the igniter stay on after it lights oven


Yes the ignitor stays on even after the burner is lit. The ignitor is wired in series with the oven valve. It sounds like the oven valve isn't opening all the way. A new ignitor should solve this problem. The old igniter builds up resistance and doesn't let the correct voltage through to the oven valve for it to open properly.

GE XL44 oven does not heat


12 years old? If it is a gas rnge yo need to get a gas technician out to fix it. I would probably say it s time for a new one. Hers is a couple of things to think of when getting a new stove. 1) Everyone wants a self clean. But 90% never self clean. can save up to $200 w/o that option. 2) 80% off people buy a stovebased on looks. A stove may not be pretty but work just as good as one that is.

FRigidare new stove installation


Loud pop means electrical fault occured. There may be and internal fuse in the oven that blew. Probably blown oven element but certainly open circuit to timer. Remove back, check for supply to oven timer. If supply is there, the timer can be bypassed to allow for oven element to work as clock replacements are very expensive.

Replacement Parts For Vintage Magic Chef stove


You probably have a 1940's model of Magic Chef. Check for the model number under the lid of the cook top on the upper right hand side of the stove. It should have the model number and the serial number, too. You will need both. The Old Applicance Club run by Jack Santoro is the place to go along with a site called "Antique gas stoves"in Georgia. Good luck with the world of vintage stoves.

DCS Mod. 60-624b62n


I am not sure of the model number of my Garland gas range (propane) I bought it in 1970 from a farmer who had purchased it at a restaurant sale. It is OLD. (so am I) I have had trouble for years with the ovens going off at times and not relighting immediately. The right oven especially.
In the last 35 years I have had the thermocouplers replaced twice, the safety valves twice, and new pilots twice. The last time these were replaced was 6 months ago by a repairman who said this was the problem. Very spendy. The ovens still would go out. I had a thought (and related it to the repairman) that perhaps there wasn't enough air circulation to the oven burners (the top burners and grill worked fine) He said there was plenty of air getting to the ovens. Two weeks later I had my son help me move the stove out another 4" from the wall and I have not had one bit of problem with the ovens since.
You can buy new fire bricks for the grill at a heating shop. I am having trouble with the thermostats now, they don't regulate the ovens to coincide with the settings. I will have them replaced next.
Every one thinks I should just get a new stove. No way. This is a great old stove, I love it.
