When it reaches temp and goes off pilot goes out

Maybe it's a direct spark ignitor so when call for heating pilot would open and spark ignitor would lite it

The flame sensor is either oxidized and needs cleaning or replacement.

read the user manual as the temp should be thermostat controlled were with gas there is always a pilot light burning when the oven is in use and when the set temp is reached the gas burner is shut off and when the temp fall below set point , the gas is turned on again and the pilot light starts the burner
by using the timer , when the time is reached the gas is turned off and of course you will have to relight it
if you do not have a user manual , download one from google or talk with a gas repair shop

Hi there.
Check the thermostat, it may have a mechanical defect (not closing contacts once it reaches the cut-in temperature).
If the pilot flame goes out with the burner flame once the ste temp is reached, your fryer may have problem with the hi-limit (premature tripping).
Regards.

I would start with cleaning the Pilot ODS Assembly and also reseating the thermocouple.

Here is a link to cleaning instructions.

Hi limit device trips prematurely (should only trip when oil temp reaches 450F). Check if the hi limit sensing bulb (located inside the fryer tank, between fire tubes) is not touching the fire tube because if it does, it will sense the heat from burner flame which is much higher than oil temp.

Set the thermostat to 350 degrees,get a thermometer and put it in the oil,when the unit shuts off look at the temp of the oil.If the temp of the oil is higher then the thermostat is bad if not the hi-limit may be.Let me know.

You will need someone who is qualified in commercial gas appliance repair to fix this.
Liabilities would render this out of reach for anyone else.

try to change the thermal battery the device that the pilot heats.. other wise there is a screw at the botton of the automatic valve.. try to increase the pilot so it can heat more the thermal battery! u dont have enough voltage to activate the solenoid valve so thats why ur pilot goes off

Sounds like the pilot is dirty
