How do I remove my electric cooktop...the conduit enter thru an L connector into the cooktop and prevents it from being lifted out...I cannot figure out how to get under the control knobs to access the connector...cooktop is a Jenn Air

You are either:
A) missing the mounting screws and brackets that hold the unit in place
B) it is stuck and will require brute force to remove
C) both

Problem: Error codes 26 or 42 after turning on too many heating elements.
Potential issue: Damaged main electronic board


Specific case: Error code 42 after turning on more than 3 elements, then already after 2, 1 until none of the cooking element could be turned on, over a period of a few weeks.
Root cause: Dying/blown electrolytic capacitor on the main electronics board.


Solution:
1) Turn off power (circuit breaker) - caution high voltage inside the cooktop
2) Lift the cooktop out of the hole in the countertop and slide it on a flat surface
3) Remove all screws around the metal housing using a torx screwdriver
4) Carefully tilt the glass top out of the housing on the front, noting that there are electrical connections in the rear, and place the rear end of the glass on a stable surface. You may need someone's assistance here.
5) After double-checking that there is no power, record the color coding of the four wires connected to the glass assembly (green for ground, white, black, red from left to right)
6) Next open the black plastic cover by removing four Torx screws.
7) Carefully remove from the connector on the left the the plastic strip connecting to the display board.
8) Carefully remove the circuit board with relays and capacitors that is held in place by plastic tabs.
9) If one of the capacitors is bulging out or showing sings of damage on top, replacing it may fix the appliance. De-soldering a bad capacitor requires some tools and skill. Replace the capacitor with at least the same capacity, voltage and use high-temp. 105C version) Alternatively, instead of replacing a $2 component you will have to replace the entire board.
10) Reassemble and done.

Firstly turn the power off. Lift the cooktop out from the benchtop and lean it against the wall. There will be a small panel where the wiring terminates into the cooktop. Remove the panel and disconnect the wiring to the cooktop. Ensure that you insulate all wires properly. You can then turn the power back on if you need to.

This is usually the infinite switch has failed. They are easy to check and inexpensive. There is a video at http://appliancehelponline.com/infiniteswitchvideo.html that will walk you thru testing this. It may be a different model but the testing will be the same. You can also enter your model # for diagrams and illustrations for your specific model. Not all models are available. All parts come with installation instructions.

the electric elements should unplug from their electric connectors. remove the knobs. see if the control panel lifts off, or screws off. after removing all of these things maybe you can tell how to get to the screws or how to remove the top of your cooktop.

There is no fuse on the unit. I suspect your house circuit is blown. If not, then a wire may have burnt off. Hope this helps!

The cook top is attached to the wood frame by brackets, just remove the screws and the electric connection, make sure the power is off from the main box, it's a 220 volt wiring and then just lift the top off. to remove the glass, look around the edges and you should see some small screws, just remove them and the glass should lift off.

1. Turn off the power at the breaker box.
2. lift off the air grill.
3. remove the two screws at the front of the control switch panel (escutcheon)..
4. slide the control panel forward until it disengages, then lift up to expose the switch assembly and wiring.

Hello
Yes their is a way, you need to unplug the power, and look for the brackes that holds the cooktop to the counter, remove those scrwes and lift the cook top, then look under the top lip and you will see small scrwes, remove those and the glass will lift, then just reverse the steps.
Hope this help!!
