Why does my electric oven take forever to preheat?
Just got a new Samsung electric range last year and it's taking like 15-20 minutes to hit 350°F. My old gas oven was way faster. Is this normal for electric ovens or did I get a lemon?

Don't assume it's broken just yet - electric ovens genuinely do heat slower than gas, and 15-20 minutes isn't unusual for newer models. Samsung ranges especially tend to take their time reaching temp because they use convection elements or precise heating cycles. The tradeoff is that electric usually maintains temperature way more consistently once it gets there, which is actually better for baking.
That said, there's a few things worth checking. Make sure the oven door seals properly - if it's not closing tight, heat escapes and it'll take forever. Also check if your range has a "fast preheat" or "turbo preheat" mode buried in the settings; some newer electrics have this but it's not always obvious. If you're not using the convection setting, switching to regular bake might speed things up slightly, though convection usually preheats faster anyway since it uses more heating elements.
If it was noticeably faster in the first month and now it's crawling, the heating element might be degrading, but that's rare on a year-old range. More likely you've just gotten used to gas speed and forgot how different electric feels. That said, if it's *significantly* slower than when you first got it, call Samsung support - they might walk you through a calibration or swap it out if something's genuinely off.
Electric coils take time to build up and distribute heat evenly through the whole cavity, so that lag is real and not a defect. One thing worth checking: make sure your oven racks aren't blocked or sitting too low, since air circulation matters. If you've got the convection setting, that can actually speed things up a bit since it forces the heat around, though it uses more energy. If it's been doing this consistently since you got it a year ago, it's probably just how that model behaves rather than something wearing out.
Electric resistance elements transfer heat less efficiently than gas flames, so those longer preheat times are actually pretty standard - I switched from gas to electric a few years back and had the same shock when my old oven was hitting temp in 5 minutes and the new one needed nearly 20. Check your oven's manual to see what Samsung lists as normal preheat time for that model; if you're within range, it's just how electric ovens work, though you could also verify the heating elements are actually getting hot by looking through the window when it starts up.
The folks above are right that electric ovens preheat slower than gas, but there's a catch - 15-20 minutes for a newer Samsung is on the long side even for electric. Most electric ranges get to 350 in like 10-12 minutes, so yours might actually have an issue. Before assuming it's a lemon though, check if the heating element is making contact properly or if there's debris around it, and make sure nothing's blocking airflow inside the oven cavity. If it's still dragging after that, it's worth contacting Samsung since you're still under warranty from last year.
