GT - your element is an original replacement element from Luhr-Jensen (Little Chief Mfgr). It used to have a spiral element in it. Your current element replaced the spiral element. This is found on the older top loading Little Chiefs.
The replacement element part number is 9810-000-0000, it's a 175w round disc and Luhr Jensen sells it for $33.50. You can call them at 800-535-1711.
In my opinion you don't have a problem with the smoker though. Like others have said, you really need to put the box that it came in over the top of the smoker to effectively dry the fish. Either that or keep the fish in for another half day. I found that I'd leave my fish in the Little Cheif for about 10-14 hours depending on fish size, outside temperature and if the wind was blowing or not. if there is ANY wind you absolutely must have the box. The instruction manual also said that if the temperature dropped below 45 degFarenheit that you should use the box to insulate it. They do make a insulating blanket for the Little Chief now. It's part number 9999-940-0000 and they sell it for 24.99.
All that aside, before I spent any money on any of the above, I'd go out and pick-up a Big Cheif, cost around $70. You can do twice as much fish, you get the box it came in and it runs much hotter (I've owned both). I can do a full smoke in about 7-8 hours with the Big Chief.
BTW - as other have said, one of the biggest keys to a successful smoke is to let the meat dry and get tacky before you place it in the smoker... There's a term for what happens to the meat. I can't remember it, but this needs to happen for the fish to smoke proplerly.
Good luck!
