Oven temperature Sign In/Join

Has anybody tried the sugar test to test if the temperature of your oven is right?

Some background. Made some french fries in the oven last night (425) and they did not crisp as much as they should. A few days before I baked rolls (350 I think) and they were ok but not browned much but not bad. This is a new to us house.

I will go to town to tomorrow to find oven thermometer but in the meantime I thought I would try the sugar test. It melts at 366. At 360 it melted some but not all. I raised the temp to 365, waited 15 min. And tried with a new batch; less of the sugar melted. Raised it to 370,waited 15 min for temp to come up before I put sugar in. It barely melted.

It just doesn't make sense to me. It is a digital control electric oven. Does anyone have any ideas what is going on?

No sugar test. But when you get that oven thermometer, check it in several different locations in your oven. You will be surprised how much the temperature varies from rack to rack and front to back and middle.

Really!! I know there is a slight difference front to back but side to side too? Oh my. How much of a difference can one expect?

It's been so long since I've checked mine that I don't remember.

I found out DILs oven is drastic from one rack to the other!!! Made a difference in good cookies and burnt cookies! Frown

I had to buy a new oven this year. It's electric - I have always had gas and that's not an option here.I was told not to buy oven thermomter as they can be off by 20 degrees. Bought one anyway. When I set my oven to 350 it registers 350 on the nose. All my baked goods were coming out overcooked. Called the store and had them send someone out to check. He came with his gadgets and checked and said it was reading perfect. Baked goods still coming out over baked. I'm now in the process of playing with different temps and checking my baked goods at least 10 minutes earlier that suggested times (I'm not real comfortable with this as edges can be over cooked and centeres not done) I don't know if this is an electric oven thing or not but never had this problem with a gas oven in the 50+ years I had used them. Very frustrating!

I've had gas for most of my life.

Wait a minute...let me rephrase that!!! LOL

I've had gas OVENS for most of my life. I now have an electric oven. When we moved in, it was only 2 years old. Something I baked didn't turn out right so I bought an oven thermometer. The oven temperature was not right. The manual told how to "calibrate" the oven up or down a few degrees. I did that and am satisfied with it.

We were at stepson's several years ago...going to stepdaughter's in the same town for Thanksgiving. I took my stuff with me to cook at stepS's house. When I opened the oven to check on the cheesecake...it was done and cracked. WOW! I found his manual and reset the thermostat on his oven. Baked my next dish and was right on the money.

Beedeeess, I think it is just your oven. I've had both electric and gas and have had both adjusted. This one just had me confused.

Oh, I tried the sugar test again and it melted it at 380, making the oven 15 degrees off. I then tried a few french fries and they came out correctly.

I'm still heading to the store for the thermometer tomorow. It will be interesting to see what part of the oven reads differently.

Beedees - could it be your bakeware? There are so many types out there, and many recipes now provide instructions for glass, dark metal, light metal, etc.

We have a new dual fuel range that was put in last year. Gas cooktop, electric (convection) oven. It has the built in thermometer, but with just the two of us, I rarely cook large items that require a temp check. This has been a big change from the teeney tiny wall oven that we tore out. Horrible thing - couldn't cook anything in that.

I love electric ovens. That said, there can be problems of course. Double check the temps as stated. Nothing worse than having to fiddle with recipes to get them to work, all because the appliance isn't working right.

When I was first married in 1967 at age 19, I didn't know how to cook at all and we had a gas stove with no knob for the oven. Where the knob belonged there was a twisted NAIL to operate the darn thing. My husband bragged that he could use that nail to set the oven at any temperature needed, even 374!!!!! Smile

I did get the thermometer and now am more confused then ever. At 325 it read 325 if I waited longer for it to warm up than the preheated time called for. But at 425 it read 450. Now I don't know if it is the oven or the thermometer.

At least I do know I have to leave a longer preheat time. I will be making a cake and maybe some cookies this week so we will see how that goes.

Check reviews on Amazon for the thermometer you purchased. Some ARE better and more accurate than others.

Maybe the thermostat is broken. I killed off the one in mine when I was cleaning the oven. The repairman was here for 3 hours with the oven on and the measuring the oven temperature at intervals. I had the same odd temperatures readings as you are getting. The repairman said that thermometers that you buy it in the store aren't very accurate but you can purchase a good one.

There was an article in Consumers Report, and another report on TV about oven temperatures, and how they can vary off the mark by as much as 150 degrees during a cycle.

AT THE TIME, the GE Profile was the oven that varied the least, by 25 degrees either way off the mark.

It's not about a good brand vs. a cheap brand. It's the nature of most ovens.

Don't know if it's been updated or not.

I have a GE Profile electric stove and the oven is 10 degrees off. I bake cookies at 360 instead of 350 and they are perfect in the 13 minutes the receipt says. My stove is about 8 years old, if that makes any difference.....smooth top and love it.


love life

May, ditto on all you just wrote. I have the GE Profile, for about the same length of time, and my baking is sooooo much better, using the same recipes that would fail in other ovens.

Smooth top, too. And, love it!

My Magic Chef stove is pretty old but I have never had any problem with oven temperature. I set the temp at whatever the recipe calls for and the results have always been fine.

I make my living checking temperatures and temperature uniformity in industrial sterilization equipment.

The temperature controllers in household ovens are not calibrated to the accuacy needed in industry.

Controllers drift. Even if the controller was right when it was installed it may be wrong soon after.

Most purchased temperature gauges have similar problems. They are fine for determining uniformity, not so good for determining temperature.

The melting point of sugar is a range, not a point. Different samples melt at different temperatures.

I don't know a quick-and-dirty way to check the accuracy of your oven.

Sorry to comment so late on this. I completely forgot I took note of America's Test Kitchen method for testing oven calibration. Here it is:
How to check oven calibration
~ Set oven rack to middle position.

~ Heat to 350° for at least half an hour.

~ Add almost 1 cup of water to an ovenproof measuring cup. Check the temp with an instant read thermometer. Add water - warmer or cooler - to adjust water to exactly 70°.

~ Set the cup into the oven and close the door. After 15 minutes, remove the cup, swirl the water to even out any hot/cold spots, and measure the water temp. It should be within a degree or two of 150°. If not, the oven needs calibration.

~ To avoid shattering the glass cup, allow the water to cool to room temp before pouring it out.

Well, I have cooked 2 batches of cookies and a cake. Cooked for minimum time and they are okay but I still am unsure. Making ham dinner today for out of town relatives. Hope it comes out okay.

Will try the water test next week when I have time. Thanks.
