Any One Out There Know Anything About Commercial Fryers?

[RamFan503]

Unfortunately, my local guy is in jail last I heard.

I was wondering if any of you out there know about commercial gas fryers.

The problem with one of mine is that once I turn the thermostat on, the pilot goes out. It doesn't matter whether the gas valve is still on pilot or if it's turned to on. As soon as I start to turn the thermostat dial, the pilot light goes out. I am guessing it has to do with the thermo coupler but just not sure.

Any help or thoughts would be great. I'm having quite a week with my ice maker and one of my refrigerated prep tables going out this week. Really not wanting one of my fryers to be added to that list.

Thanks,

Stu

I'll put YOUR knob on backwards!

Faulty operating unit.

I have no clue really on the commercial. But the first thought I had was the thermo coupler as well. I've had to rig my propane burner up for beer making by bypassing the timer unit that controls it. Sounds like there could be some wiring issue that causes the thermostat to make the pilot malfunction.

If that's not it, my vote is that the flux capacitor took a dump.

sounds like a P.O.D. to me also

I'd agree except that I've spent too much time operating and fixing these damn things. Just the first time I've ever seen this particular little stunt it's pullin'. Little did I know I was asking people with less of a clue than yours truly.

Fuckin newbs.

Galaxy Quest fan?

I hope thats a joke.....

[RamFan503]

Nothing showed. My computer is siding with some of my equipment around here and having major suckage issues.

Did I get the wrong reference with the Galaxy Quest thing? Thought they used that term in the movie.

 

[RamFan503]

I hope thats a joke.....

Why? That movie is funnier than hell and I thought they used the term Flux Capacitor in at least one of the scenes.

90% chance it's the thermocouple. They are designed to fail that way. Not hard to change normally. If you have a second burner you could swap them out just to verify. Not knowing the exact type it's hard to say what value it has, but checking it with a Ohm meter and a match can give you a definitive ans. It's dielectric so when it senses heat it closes the connection and lets the gas valve stay open. If the reading doesn't change when it has heat applied then its bad. Tho some K types are opposite, they open the circuit when heat is there. That doesn't matter as long as the readings change.
The other thing it could be is a bad regulator. If it doesn't open letting gas thru the thermocouple won't sense the heat and close the valve.
This is easy to check. Hold a match in front of thermocouple and if it senses heat the valve should open and let gas thru. if it opens and gas doesn't go to burner then that's the problem. Long arms are handy for this because the downside is not needing to shave for a month.

Finally - someone giving some actionable answers. Thanks man. So should there be no continuity to either wire if you touch the end of the thermocoupler and either of the leads that connect to the valve? I'll try the lighter trick. I have it removed from the unit now and can try that one pretty easy.

 

[RamFan503]

OK - So I set the end of the TC in the flame of one of my stove pilot lights. I get an open circuit no matter what I touch the contacts to. In other words, there is no difference in the reading cold or after getting heat. It's a 1 and doesn't change.

I have one ordered and am picking it up tomorrow. I'll let you know if it works when I hook it up Saturday morning. Again - thanks for the insight. Let's hope the new TC fixes the problem. I can dig a $49 fix. I'm already having to pick up a $3000 refrigerated prep table tomorrow as well. It's been a really rough week for my equipment budget.

Not denying galaxy quest is funny. I like that movie. Not sure if they ever use the term flux capacitor in it though.

Flux Capacitor is from "Back to the Future". Doc Brown invented it and its what makes time travel possible.

Ah. You're right. Now I gotta watch Galaxy Quest to see if they used it too. For some reason I'm picturing Tim Allen saying it. That's my story and I'm sticking to it.

It's all good. Sounds like you've had a rough week. You'll get my cheesy 80's movie references next time.

 

[RamFan503]

Finally a bright spot. The problem WAS the thermocoupler. $48 part and a ten minute fix. I can dig those kinds of repairs. Thanks @Yamahopper for the intel on testing it and the rest of you smart asses for simply being smart asses.

Cheers,
