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.

most of the cooktops are strong eneough to resist against scratching for you to use a razor blade to get off stubbburn stains, once they are gone their is a product called cermabryte which can polish and remove leftover buildup.. hope this helps

hook the red and yellow off the new stove to the two hot phases-then connect the white on the new unit to the neutral power connection and finally the green wire can hook to the same neutral wire also as long as the power comes directly from the main electrical panel in the home, but not a sub-panel

By far the most common cause of what you describe is
Demo Mode is turned ON


1-bq0fxqg1zh3iovhrefhl5oob-1-0_1.jpg If am certain you have already checked to make certain there are not too many appliances plugged into the same outlet, and that you are not trying to run your Bosch through a power strip or so-called "surge protector", which are worthless troublemakers.

again.


From what you have described your Frigidaire oven lock is stuck open and you are receiving error codes "F9" and "DR". The "F9" error code stands for runaway temperature (overheating). This could be an issue with your RTD (Resistance Temperature Detector) or the EOC (Electronic Oven Control). I would recommend performing a reset on your oven and you can do that by disconnecting from your oven for ten minutes. The "DR" code means that the door is not closed or the door latch is not recognizing the door is closed. This could be an issue with your door latch or control panel. If the reset does not help correct your issues I would recommend having a professional technician out to perform a proper diagnosis and repair.
