Vulcan 1gr65 fryer, installed new thermopile but pilot wont stay lit, any suggestions.

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.
