gE 240v Advantium not browning

GE 240 volt Advantium works but doesn’t brown (like the bottom of a pizza during speed cook functions).

It works fine otherwise. Microwaves, and runs convection as it should.

I assume it may be the Miraclon reflective heater element.

Any way to test the element after, or before, removal?

Thanks,

What was the solution to your advantium not browning pizza bottom. Mine also did not brown on bottom during convection bake, but BISCUITS browned perfectly! I guess I’ll try cooking pizza on biscuit selection!
