What is causing my imperial fryer to burn my fries when the thermostat se at 300 this wasb not happening before

SOURCE: Imperial deep fryer IFS40 pilot lights, turn on

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.

Is this fryer propane?It sounds like the baffles in the tank are clogged.If you remove a burner shine a light in the baffle,if you see alot of soot use a shop vac and clean it out.Let me know.

SOURCE: imperial gas fryer problem, when the burners are

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

When the whole unit shuts down including the pilot light the thermocouple is not working properly. The thermocouple is what tells the gas safety valve that the pilot light is lighted. When the thermocouple fails and does not send the milli-volt (mv) signal to the gas safety valve due a failure the gas safety valve turns off the gas supply. (i.e total shut down)
If you have a handyman around you can have him disconnect the thermocouple from the gas valve control and clean the mating area in the gas valve and on the bitter end of the thermocouple. After cleaning then reconnect the thermocouple. This sometimes corrects the problem. FYI you can get a thermocouple at most any large appliance parts supply. (You will need to the know total length) It would be even better to have the old one in hand during the trip to the parts store.
