I have purchased 11 brand new imperial fryers and i continually keep having pilots that dont stay lit wnhen i try to turn it to on and its not always the same fryers that have this problem they continually change what should i do they're brand new fryers i shouldn't have this problem

When the pilot goes out and won't stay lit is is usually because the Thermocouple safety device has failed.

The burners should never be on when the thermostat is off. That is incredibly dangerous. You need a gas registered service technician.

If it has a thermocouple you should check it next.

The reason is the pilot generator will hold the safety magnet but it won't operate the solenoid.
It is old and weak.Ain't putting out enough power to operate the solenoid. Get a new generator

Have a lighter handy (I use one of the elongated ones for caravaners)
in-between the burners is a pilot light (top right) keep the lighter flame where the gas comes out.
On the right hand side of the fryer at the bottom is a gas valve with a little black knob.
Press and hold the black knob in and gas will come out of the pilot light and ignite by the lighter flame. You need to hold the button in for quite a while. (until it stays lit)
When it stays lit depress the little black knob and turn it anti clockwise. Gas comes out of the burners and ignites from the pilot light. When it reaches temp. it will cut out.
To turn it off turn the little black knob clockwise. To turn the pilot light off, push and turn clockwise.

Remove the thermocouple and clean the threaded end carefully.
Then screw it back in and try it.
If it continues to extinguish,replace the thermocouple.

You have a bad gas valve. It's not reading the signal from the thermostat. The gas valve is stuck open.

need tochange termal couple

check the high limit it tripping out

Try to clean the pilot orfice,ive seen even though the pilot stays lit it doesnt have enough millivolts to energize the gas valve.Did you check the wiring really good?

I had a very simular problem. My fryer would do exactly as you described, but sometimes the pilot light would stay on until the burners tried to re-ignite and then it would go out.
I finally had to call the gas company. They took the pilot light apart and cleaned it. The fryer works perfect now.
Hope this helps!
