- Check your voltage. Some people may have high voltage like 245 volts where you should nominally have 240 volts.
- Make sure you don't have a 208 volt kiln hooked up to a 240 volt circuit. This is dangerous because the kiln will draw more amps than it is rated for which will overload the power wires and other components and could cause a fire.
- Check element ohms and compare with factory values. (See CHECKING ELEMENT OHMS).
