Is there a way to test induction cooktop?

I have the True Induction cooktop in my mh. Lately it seems to be cooking slower than it seemed when first installed. I was wondering, since I know many others on this forum have the same cooktop, is there an accurate way to test the function of this cooktop? How fast should it boil 1 qt of water? I haven't measured it, but it doesn't seem to really give a rolling boil even after a long time.

Are you using different pots & pans? The composition of the metal in the pan can make a huge difference in the heat transfer. The less magnetic the metal, the poorer (slower) it will heat.

Do you have an IR temp gun? If so check the temp using several pans at the same cook time. You can compare the burners also and see if the unit comes up to the set temp.

I discovered that if you use the TEMP mode instead of the HEAT mode the unit draws about 30% less current. So using the HEAT mode at 10 will heat fastest than 450 in the TEMP mode.

I always use heat mode on number 10 for fastest heating. I also use magma induction cookware, and I have always used them. Additionally I sent an email to true induction, and I will see what they reply.

"Cbones".....I know of at least one person who said theirs wasn't working properly and had to have it repaired. I'm guessing you'll need to speak to the TruInduction people to get some type of test procedure or calibration numbers.

One quick test would be to set two pans on the cooktop, both with water and set one at 10 and then turn the other side on. The side set at 10, should be reduced by the number you set on the other side. So if it's set at 10 and you turn the other side to 2, the first side should drop to 8. This might give you an idea if the electronics are working.

This would depend on a lot of things if the unit is working properly. Altitude, type of pot you are using, temp inside the rig, temp of the water before adding to pot. many factors involved.

FYI - The max power on the True Induction when both sides are in use is "7". So a 7/3 split is what you'll get.

Really? How long have you had yours? Maybe they changed it since we got ours, which was about 2 years ago.

Yep - we bought ours in January 2014 and this is how it works.

I think my point was missed. It doesn't matter what setting you use 6/4, 7/3, etc, but to check if that was even working. Do both burners come on and change as you add power or reduce. It was just a thought to see if the circuits are working.

This being one of my "Busy" days I will tell you how to do the research.

First: This is not for the faint of math.
Using the internet translate WATTS to BTU's and calculate how fast it SHOULD heat water.

Now.. You need a steel (Magnetic) pan something with LOW heat index (Use Interenet) NOT Cast iron which has a high heat index. The heat index is how much effort it takes to heat the pan and how much heat it holds.

now put a measured QUART of water in the pan, stick in a digital cooking thermometer and read the temp.. Fire that mother up and start a stop watch.. When the temp hits an arbituary point (Say 200) stop the watch

Now you can do the math to figure out how many watts hit the jar as it were. NOTE: it will not be 100% efficient. use this as a benchmark

NOTE: REad the voltage at the outlet (Plug in or pass through meter or Kill-a-Watt (use pass through) for this test... If your voltage is low it WILL COOK SLOWER.

Get someone else to do the same test, compare.. Keep your results as a baseline, if it starts cooking "Slower" re-do the test and compare.
