The thermostat in my hot tub has the exact same number on it which is odd, because hot tubs aren't supposed to go over 120 degrees. I wonder if the number stamped on the side of the part is fairly generic or merely refers to the casing.
If that's the case, you'll need additional info such the power rating on the fryer I suppose. I think fryers cooks at around 350 degrees -- maybe higher.
Also, mine has a sticker on it that reads TD103 149 and then below that 110F CR. I'm guessing that last part means 110 degrees Fahrenheit is where it tops out.

My keating fryer heats the oil fine to temp set on thermostat but will not re fire when oil temp drops unless I push the high limit button. Don't know if the problem is the themostat or high limit...

Sounds like the thermostat is working because it does heat to the right temperature, right? The high limit switch is to shut it down when it gets too hot, so why that helps the unit relight and heat up is strange? Is this gas or electric? Since hitting the reset or high limit button is what is working, I would start there, and replace that... I don't think either part is super expensive, so replacing both wouldn't be too expensive, especially since you have one of the best fryers ever made... Keating is number one in my book, and I know they are expensive to start with, but these two parts shouldn't be much....however I would start with the high limit switch or reset button... If you need a part, we can get you a price....I'm Susan with Restaurant Equipment Outlet, Cincinnati, Ohio, 888-542-5959, or you can ask for Paul too. Thanks, Susan REO

My fryer heat up to 285 then quit then try to light but want,

sounds like the high limit is doing what it is suppose to do. Check the actual temperature of grease with a perometer and see if it matches temp on computer if it is more than 10 degrees off or fluxuates irraticly change the temp probe. If it is dead on change the high limit.

Can i disconect the hi limit switch and still use fryer

Hi there.
Hi limit switch/ device on fryers acts as safety device. It cuts gas supply on burners when it is triggered by high oil temperature in case the temperature regulating device failed to avoid further damage on equipment, property or life.
It is not advisable to operate the equipment with bypassed hi limit device.
I suggest to have it replaced first before putting the fryer back in operation.

The High Limit is a self resetting thermostat that acually works like an oven control. If the fryer is too hot it will cut off the gas burner valve voltage:
OEM PN is 00-854453
Original PN VUL854453

Source 1
Source 2 Must log in.. new account

The 854453 number comes up often in the part search for the high limit.
The high limit contacts can be checked and reading the NO and NC terminals. This control / switch is normally closed until opened by heat at 450 Deg F.

Thanks for Choosing FixYa,

Fryer quits heating have to hit reset switch

This button should be a high limit switch. If it is a small red button mounted to a 2" x 2" or so device. You most likley have an issue with the thermostat letting it over heat. The best thing to do would be to replace both the thermostat and the high limit for safety reasons.
