How to Fix an Element Wire in a Toaster Oven
The heating element of a toaster oven is what produces the radiant heat that toasts the bread. Most toaster oven heating elements are made of nickel-chromium alloys that are highly resistant to electricity. A high resistance means that the metal has difficulty conducting electricity and will produce heat. Many times the hardest part about replacing the element wire is access the wire. You first need to disassemble the toaster oven to replace the element wire. Make sure the replacement element wire is the same type as the old one, otherwise you will get uneven heating.
Test each of the heating elements with a multimeter to determine which element is broken if there is no visible broken wire. Touch a probe to each end. A broken element will read has having very high resistance.
Remove the broken heating element by unscrewing the ends of the element with a screwdriver. Depending on the type of toaster element, it may be held into place with rivets. Remove the rivets and remove the defective element.
Insert the replacement heating element where you just removed the broken element. Make sure the replacement element is the same structure, material and heat rating as the old element. Secure it into place with new rivets or screw it into place with a screwdriver. Again, the method of securing the element into place depends on the type of toaster oven.
