Why is my oven heating up so slowly?

I have an electric Dacor Epicure oven which is taking a very long time to heat up. The manual says it should take 11 – 14 minutes to get to 425 degrees. Mine is currently taking 35 – 40 minutes to get there and never reaches a temp highter than 475. The oven is supposed to go to 550.

Do I have a bad heating coil, temp sensor or something else? It’s plugged into a 220 outlet. The oven does get hot and when it’s at 425 it really is at 425 (tested with an oven thermometer). It just takes forever to get there.

Update:

I’ll add some more info to help target the responses…

1. The main point of my question is why it takes 35 – 40 minutes to go from room temp to 425 instead of the factory specified 11 – 14 minutes. I’m aware of how to properly preheat but that’s a completely different issue from the length of time it takes to get from room temp to 425 initially.

2. The only reason I ever crank my oven over 450 is when I’m baking pizza’s. That’s a perfectly valid reason to want to get your oven over 500. I’m not baking cookies at 500…

3. Obviously, I’m not expecting my oven to get to 500 when I set it to 425…

4. My oven has a glass front door so I can see the oven thermometer without opening the door.

    It takes both elements – the broiler element and the baking element to preheat the oven. I suspect one of them is bad. It doesn’t sound like a thermostat as the oven eventually gets up to temperature. yes it should heat up to 450F within 15 minutes or so. I would check both elements for continuity or if you want, turn it on and feel the bake element to see if it is getting hot. Then turn on the broiler and feel that element to see if it gets hot. It won’t take long, so be touching the element when you turn it on. An oven element isn’t difficult to change out. Good luck.

    It is working properly. Nobody needs to bake at 475. That would burn food. In bake there is likely a safety limiter in there to prevent it from getting too hot.

    Any good baker and the manufacturers will tell you that you need to preheat for 30 to 60 minutes before baking. Really. It takes that long for the whole body of the oven to get hot and then the element doesn’t cycle on as often.

    It is only the air in the oven that has reached that temperature when the light first goes out, not the oven itself. Open the door and that heat is gone.

    If you put breads or cookies in when the light first goes out you opened the door and let all the heat out. The element immediately kicks on and burns the bottoms of the cookies. That is why people notice the second batch always comes out better. They didn’t preheat long enough.

    Although the numbers are there on the control the oven is NOT intended to ever get to 550 except in clean. I think most safety limiters keep it below 500 in bake. A temp that high with food in it could cause fires.

    And realize if you have to open the door to look at your thermometer you let all the heat out.

    You got bad information from the manufacturer and most people have the wrong impression.

    Manufacturers say the biggest cause of baking complaints was failure to preheat long enough. I was in a class requested by the manufacturers where we tested 10 different brands and models plotting the temperatures every minute. they all acted about the same.

    Yes the air would get up to 350, actually more like 400 when set at 350, in 15 minutes but when the element shut off it would quickly fall to 300 and kick on again because the oven body was still cold. It wasn’t until the third cycle, at about 30 minutes, you started to get an even temperature with small temp swings and the element heating less.

    You are trying to make the oven do something it is not intended to do. I can’t imagine why you want 500 degrees.

    I think microwave ovens have spoiled us. And we are in a rush with our busy lives but baking takes time to do it properly and it is partly an art.

    And note I talked about baking. It is less of a problem with something like a casserole or a roast that cooks for a long time. But if you don’t preheat long enough you might want to put a pan under the casserole to prevent burning the bottom from the element still trying to warm up the oven.

    Good Luck.

    The room temperature will affect it. There is NOTHING wrong.

    If you don’t set the temp. to 550, it will NEVER get to 550.

    Switch to gas. Less expensive and much more responsive.
