I wrote to the company and they said they can't (or won't) identify the thermal fuse rating, nor will they tell me where to get one. They told me to just buy a new fryer for $50. I don't want to do that, being that I know the fuse costs $2 (I just replaced on my coffee machine). The numbers on the old one are illegible. If I knew the specific rating, I think I could just scoot down to the local Radio Shack and get a new one, like I did for the coffee maker. I can find no service manual anywhere. I assume the rating has to be at least 450 degrees F, but I want to get some more info before replacing what is essentially a fail-safe protection device. If I get on that is rated to high, I run the risk of severely overheating the unit, and I have teenagers who may use it; too low, and it will blow before the oil gets nearly hot enough to fry my chicken. I know I can make the thing operate without the fuse, but I would like to replace it. Any info?
If the old fuse is open, it did what it was supposed to do. Until the cause is found and repaired it will continue to open when it is used. Take the unit in to a local service center and have it repaired or purchase a new unit. The reason the company will not give you the information you request is a product liability issue. If you install a fuse in a faulty unit and burn down your home they are concerned about an insurance claim. For $50 it is not worth risking your home with a fire and your insurance deductible is probably much higher than $50. All advice on this site is worth what you pay for it and that is the limit of the liability.
