Our Amana gas cooktop problem began with one valve which appears to locked up and will not turn. The next day another then the next day all of them will not turn. What is the problem?

on most, your push down and turn to hi to open gas valve and turn on piezio to light burner. it sounds like you have a knob already turned on . the control under the knob may need replacing. kinda an easy replacement if you get new part. check out repairclinic.com for video(maybe) but for parts for sure. be careful. gas is explosive.

Is there an orange glow in the burner area when this happens? If so then the thermostat is not shutting the ignitor off and needs replacing. If there is no glow then the gas valve is not shutting off the gas and needs repalcing

It could be locked, the valve could bed closed. r clicking is just an electric switch I would make sure the gas is turned on somewhere

Get some rust buster and apply it to the valve stem liberally. Work the shaft in and out a bit to loosen the shaft. Let that rust buster sit on there a bit. Good stuff.

If you have parts of the cooktop not working I would replace it with a new one of your choice.

Hi,
Here is a tip that I wrote that will help figure out why the burner spark keeps on clicking...

adjusment in the gas valve,i think the air is in low position,hard to adjust,find in manual how u do by using plat screw.

is gas comeing out of the hole? sometimes by cleaning the orfice hole (food and debrie will get in there and plug the hole not letting the gas come through) i get a needle and poke it.

when you say it is sparking...When you turn the dial for that specific one you want ignited... That one is sparking? If so Great. This means you either have a plug or the valve is bad and not letting the gas flow through.

All gas appliance should be diagnosed by a professional.
