Re: I replaced the thermocoupler still not staying lit.

I understand it that once the main burners go off, after the thermostat is satisfied (water heated) the pilot goes out too at the same time.
Make super sure the top of the t-couple is getting hit directly by the pilot flame. You may need to adjust the t-couples position, or even clean the pilot assemblies oriface. Double checking the connection of the coax cable at the gas valve would be a good idea too. tight but not super tight.

Pilot won't stay lit

If a standing pilot won't stay lit, the usual cause is a bad thermocouple. The thermocouple is a safety device with a probe that is kept heated by the pilot flame and produces an electric signal. Wires from the thermocouple connect to the main gas valve. If the thermocouple fails, the main valve shuts off gas to both the pilot and main burner. When you try to re-light the pilot, it goes out again as soon as you release the pilot button on the valve.

A new thermocouple is only $10 or so, and it's pretty easy to change. There are a number of how-to sites and videos showing how to change the thermocouple in gas furnaces and water heaters, and the process is similar in commercial ovens and fryers. Once you see what the thermocouple looks like and how it's installed in some other appliances, you'll be able to identify it in your fryer and see how to change it. That should get your frying again.

My pilot light will not stay lit. I have replaced the thermocouple and still will not stay lit. Can the valve be bad?

Make sure the thermocouple is deeper into the flame of the pilot light. It needs to reach a high enough temperature to produce a high enough voltage to keep the pilot light lit all the time. I do not think that the main gas valve is bad at all.

Light pilot on Royal deep fryer. Pilot will not stay lit. Second fryer has larger pilot have no trouble keeping it lit. How can I adjust the pilot so that it will 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

Pilot light won't stay lit.

Ensure that gas is getting to the pilot , or you may have a devective pressure regulator.
If gas is getting to pilot and pilot is turning off, then you need to replace the thermocouple.
The thermocouple function is to turn off the gas if there is not enough temperature, so to prevent gas leaks if the pilot light goes off.
Near to the pilot light there should a part similar to a small metal tube directly in contact with the flame. Thermocouple is wired back to the gas valve.
When the pilot is on, and temperature is steady, the thermocouple will generate a small voltage that will keep the gas safety valve open. In case the pilot light goes off, the thermocouple will cause the valve to close. When you hold the pilot light button , the thermocouple will normally reach enough temp to keep valve open.
If the termocouple is faulty, it will turn off as soon as you release the igniter button.
Replacing thermocouple is an easy repair.

Call the number listed on the owners documentation to get the replacement part.

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

What parts did you replace to do the conversion? Make sure all your wire connections are correct (hi-limit/thermostat/thermocouple connections).I repair these fryers if you need more advise let me know.
