Cooktop valves under knobs are locked

That is an obvious burned wire, or burned thermal cutoff etc

if this is a oven you are lighting would be oven thermostat would contact surplyer as faulty goods dont try repair as will void garantee

The All Off cooktop touch control turns off the downdraft exhaust

system and all surface cooking areas that are in use at the same

time.

The Lock cooktop control avoids unintended use of the surface

cooking areas. When the cooktop is locked out, the surface

cooking areas cannot be turned on by the cooktop touch

controls.

To Lock Cooktop: Touch and hold the ALL OFF/LOCK keypad

for 4 seconds. After 4 seconds, ALL OFF/LOCK will glow red,

indicating that the cooktop controls are in the lockout position.

To Unlock Cooktop: Touch and hold the ALL OFF/LOCK keypad
for 4 seconds.

What do you mean by "all four burners turn on"
Some electronic ignite systems turn on on all the burners, But just the SPARK not the gas part of the burner.
Is this what you are describing?.

there is a chaffing problem on this unit on the left side of control remove nobs remove the cover and inspect for chaffed wires or oone that has come out of the ignitor

Yes. Buy a burner module. Sears sells them also most appliance part stores. (I am assuming you have the model with 2 knobs on the grill side) The electric version of burner modules is around $100 Gas should be similar price.

My husband figured it out.....when we took the knobs off, I, of course, washed the area they had been sitting on, thereby spilling some water into the open part which contained the wires leading to the igniters.  A short time with a hair dryer sorting things out.

grab hold of the installed burner cartridge at he top of unit and pry up slightly, should lift up without much effort, if not try lifting front side. they jsut lift up and slide back in no screws hold them in place

I just ordered one of these---sounds like people are not happy with this model---please get me more info
