My deep fryer pilot somtimes goes out after burners ignite
I assume this is a natural gas fryer....Are your jets clean? That is an issue sometimes, and those are the small holes that your flames come out of....Is your gas line clogged anywhere....? I don't sell Dean fryers, not too impressed by that brand, as they leak quite often, and then Dean won't honor their warranty program....so I'm not as familiar with their products, however on some brands, the thermostat dial itself should not be turned to the holding temperature until after it lights and is fully on...Do you turn it to say 350 degrees right away or wait for it to light before selecting your temperature? Thermostats themselves going bad is the number one issue with fryers, so it could be that. To clean out the burner jets, we use a compressor and blow them out clean...You can also use a small brush or skewer to clean them out. I would eliminate everything you can that has no costs involved first, and then move to parts that you have to purchase. If you need a thermostat, I could get you a price on Monday... Our toll free number is 888-542-5959, Restaurant Equipment Outlet, Cincinnati, Ohio. We would need the brand/model number and serial if you have it also. Our service tech who specializes in gas products is off Monday, but there are other people there who can help and get you pricing on parts. I won't be in until after lunch myself Monday, but check out what you can, and if nothing works, then call us on Mon or Tues next week.
Everything is closed up until Monday, so we can't order or get pricing over the week-end. Good luck, hope this helps.
