Only high setting works on burner

Based on the symptoms described, it is possible that the issue lies with the ceramic element that the burners connect to at the back of the burner unit. This could be causing a short circuit between the two burners, which is preventing the large burner from being adjusted lower when both burners are on.

It is also possible that there is an issue with the wiring or connections between the two burners, which is causing a similar short circuit. However, given that the smaller burner appears to be working fine, this seems less likely.

Another potential cause of this issue could be a problem with the control board or another component of the stove's electrical system. However, given that replacing the infinite switch and receptacle for the large burner did not resolve the issue, it seems less likely that this is the root cause.

In order to determine the exact cause of this issue, it may be necessary to consult with a professional appliance repair technician who can diagnose and repair the stove.

Faulty switch if you are changing it yourself remember turn off power and take your time, take a photo to compare so you get it right.
Good luck. Ray

Hello,

The switch for the right front burner is defective and needs to be replaced,its bad as far as internally when turned on no matter what its set it the interal contact is stuck on only high so their is no setting it will work on except high. By replacing the switch it will work on the various settings and not just high.

I'm having the same problem! Except I'm not guarenteed any heat even on high.

Bad control or infinite switch. replace the switch for that element and you will be good to go.

I'm going to assume this is a new installation, either way, it sounds as if you're only getting one leg of your 220v circuit, which wld run the timer and lights but not enough to power the burners. This is prly not something you shld try and repair yourself as a 220v circuit can cause some serious damage. At the least, you could first, TURN OFF THE BREAKER and then check the connections to the cooktop to make sure all connections are secure.

You need the switch for that burner. The contacts inside are stuck together. You will need to pull the unit and separate the glass from the lower body to access it. To get the right switch you need full model and serial number located on a plate at the bottom of the unit.

Your ability to perform this is dependent on how mechanical you are. The Whole unit must be removed from the counter opening and the base unscrewed from the glass, remove knobs before disassembling. For someone mechanical this is not difficult. De-energize whole unit first.

Once the two pieces are separated the remainder is mechanically easier. Disassemble the box on right containing the switches and replace the correct one. Reverse the process for reassembly. Good Luck

not related any further then sounds as if you have 2 burner switches gone bad,and actually the front right burner is controlled by a electronic control circuit board part retails for about $160-$200 part number 12002723, and left rear switch about $30 part number 74007841 . uint needs to be uninstalled from counter and parts changed by removing the bottom panel

Switch that controls that burner is bad and needs replacing

I have had this same problem on the JP350.

I have replaced the switch several times, and am now tempted to replace the heating element and the switch the next time it becomes constant (currently, it is intermittent... which has led to some burnt food).
