can be bad but look good

yes you can test with an ohm meter

make sure the breaker is OFF.

With both element leads removed from element, check elment reistance

Guessing here but the resistance should be failry high;.
Check the resistance foir a 100watt bulb if my conceptual thinking is
correct the element's resitance s/b about 15 to 20 times higher. Or
you could compare it to the broiler element.

Checking is easy but I just replaced an element in a 25 year old GE for
my mother. Element looked good but was bad, I never checked the
resistance.
