cce3451w induction cooktop slow to heat

[John Rounds]

I have a Jenn Air induction cooktop that is slow to heat on induction and never gets very hot.  Cooks ok but have to use HI just to cook eggs.  Large pot never boils.  The unit always works (over a year), just poor performance.  We previously had the same unit that operated very well.  I bought this unit used off Ebay about 2 years ago for installation in our new house due to the price on the new models.
Servicetechhelp.com states there is a bulletin "TS Bulletin 753, 01/02. Customer complains of long time to boil when using the induction cartridge." but it is available only to "membership paid service techs".
All electrical connections are correct and tight.  The wiring diagram shows 2 potentiometers in the induction housing.  Adjust them??
Any help at all would be appreciated.
Thank you,  John Rounds

The least I can do is show you the document:

THANK YOU!!!

OK - I read the bulletin.  I sanded the pads on the induction units to even out and minimise the clearance to the cooktop surface.  I added some springs to ensure the induction units were against the cooktop surface and put it all back together.  Now I await the verdict from the spouse!

BTW - what do the 2 potentiometers in the induction unit do???

They are variable resisters that change the power output to the burners.

The induction burners are working better but not as well as our previous unit.  What is the basis for the adjustment of the resistors.  Can I measure the output with a Fluke meter for adjustment??  Thanks for any help.
