My deep fryer pilot light dose not stay light, why is it happening?

The thermocouple is bad or the pilot light is not adjusted to heat the thermocouple to the point where the safety shut off stays on.

clean pilot light first , you may need to change thermopile or thermocouple see what mille volts you get from thermopile need 600mille volts

I don't think it is the ortice it is most likley the thermal coupling change it and this will keep your pilot light will stay lit

Most fryers have pilot lighting instructions on the inside of the door. If yours doesn't then find the gas valve, turn the knob to the pilot position, push in on the knob and light the pilot. Keep the knob pushed in after you lite the pilot for at least another 30 seconds. The pilot should stay lit.

there is a small adjustment screw on the gas valve,turn it clockwise to increase pilot,if that does not work the vent cap on the gas regulator on the back of the unit could be stopped up,remove that cap ,clean out or replace unit can operate without it just fine.If you increase the pilot and it still wont stay lit replace the thermocouple

Hi there, it sounds like your thermopile, for the pilot, is failing during use, when this happens, the small DC voltage it generates is less than the gas valve requires to stay open, and shuts off the pilot, which shuts off the main burners. Another thing that could be happening, is the hi limit is opening prematurely, instead of shutting of the pilot at 450 deg. it now is opening at 325, or 225 or 250. Sometimes the sensing bulb gets broken where it pass's through the oil tank causing this symptom. If you temporarily bypassed the hi limit to test this also, and it still goes off, you need a thermopile. If it stays on, check your temp with a reliable thermometer, and see if it reads fairly close to your setting, if so, then you need a hi limit.
Hope that helps, and thank you.

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!

i had this trouble with a different fryer. We had lpg instead of natural gas. check youre using the correct gas.

my deep fryer pilot light lights but wont stay on!

Wrong voltage thermocouple? must have 400mv, residential uses 25-40mv.
