OT frozen stove gas valves

Daughter-in-law bought a new to her house. Has a Jen Aire counter top burner unit with 4 burners, and some sort of hot air burner. Suspect it is the forerunner of the now popular air friers. Anyway four of the six burner valves are stuck. I've put all the torque I dare on the shafts, and drowned them with spray silicone. No luck. Think cook top must be fastened down pretty well, as can't shift it on the countertop.

Any suggestions?
 
Did a package of owners manuals come with the house?

If not you can probably go online and find the manual for the stove top. Go directly to the manufacturer, not through a second party.

The manual will give some insight how to get the unit open, possibly a parts break down.

If the valves are like old school gas valves, they are a taper seat with a cross drilled taper plug that regulates the gas flow. There is a special grease that seals the valve and lubricates the stem so it will turn easily. Just a guess, could be entirely different. But sounds like the valves are stuck from not being used, and will need to come apart.
 
Yes, the old valves were tapered plug valves, with a spring on the bottom to keep them as tight as possible, and a screw to retain the spring. They could be gently tapped up if they became stuck, and there was a lubricant called stop-cock grease for them.
 
As mentioned, owners manuals are the place to start. If she bought a warranty on the appliances she might get the cook top repaired or replaced under that warranty. If not, a service call will answer a lot of questions without breaking anything.

Does she like the cook top and planed to keep it or did she plan to replace it anyway?
 
Tap on the shaft a few times. Then clamp a small pair of vice grips on it. Try up and down first and then back and forth. It has to go down just a tad and then it will turn. Take your time.
 
Push in and turn counterclockwise to light the burner is the way most I have used worked.

Not sure what the real estate rules are where you are but here if an appliance is included in a sale any repairs are the sellers responsibility if it is not functioning when the buyer takes possession.
 
silicone spray won't do much on a frozen valve--use some good penetrating spray (kroil oil) and let it soak for a day or two
 
Had to replace the valves on our kitchen range a while back. Had previously worked on the valves, and a local appliance repair shop told me that they used anti-seize compound on gas valves. They did not use the special lube.
