    Okay.  Check for:

    • Poor pilot flame quality (low gas pressure or dirty pilot burner)
    • Wire connection bad/poor (loose or cruddy connection; bad wire crimp)
    • Combination valve wiring improperly configured (doesn’t match diagram on the door)
    • Open hi-limit (as tested across the NC and C terminals)
    • Bad combination valve (if voltage across TP terminals is >200mV, the pilot valve should remain open)
    • Other possibilities I can’t think of at the moment…

     

    Once you employ your manometer and VOM to troubleshoot for these possibilities, the problem can be quickly and easily isolated/corrected.

    Check the over-limit safety, Pilot flame quality, and wiring.

    We must have been typing at the same time. Kool.

    I should add that a quick and easy assessment of the hi-limit’s condition can be done by draining the oil, then inspecting the hi-limit’s sensing bulb capillary tube.  If it’s beat up or mangled, it’s probably lost its charge.

    I HAD AN ATOSA FRYER ACTING THE SAME WAY. AFTER SOME TESTING WITH MY METER, I WAS ABLE TO REPLACE JUST THE MAGNET HEAD ON THE VALVE (A ROBET SHAW).

    That’s very rare.  I would check the pilot flame as being to high on that one.

    Replacing the gas valve will solve the issue.

    Not something one would do without first testing the pilot system and ohming out the valve coil.

    Don’t know what manual that is from,  But that is why we carry digital volt ohm amp meters. Measure the millivolts first at the valve.

     

     

     

    Wait,  I know where it came from.   Fryer repair for dummys.

    Hey,  I made my living on coming in after a part’s changer tried to fix it.  With a suitable price structure to support it for the aggravation.

    Your referenced screenshot is from a website that caters to DIY (do-it-yourself) repairs.  You happened to miss the first TWO steps BEFORE coming right out and saying to replace the valve. 

     

    Here’s what you skipped:

     

     

    The hi-limit in the OP’s (original poster’s) Vulcan fryer doesn’t have a red reset switch.  Even if it DID, that component sees much abuse (due to its sensing bulb design) and should always be first to receive initial scrutiny. 

    While the steps explained ABOVE are suited for DIYer, a technician would quickly assess a failed hi-limit with a VOM.

     

    FWIW:  I’d love to simply pull up a chair and observe a DIYer intent on swapping the wires on the hi-limit in a Vulcan fryer.  I think that’d be very entertaining.  I also think that after the first twenty minutes, they WOULD BE WILLING to pay ME to do it!

     

    SO, use that website as you may, but realize that technicians DON’T.  It’s silly, dumbed-down and falls FAR short of conveying the skills that we technicians possess.

    fipe does say in his profile that he has 0-5 years experience on the cold side. That would make him a tech, albeit one not experienced on hot side.

     

    Also, welcome fipe!
