My Apr 2004 date of Manufacture Apollo half time oven has served us well, but recently, it started making grinding noises and only one half of the Convection burner coil would glow (but still cooked fine). But most recently, after some further journeys, slideout cycles, etc, the grinding noise is gone and both/all of the convection burner coils glow now!
However, the Convection Oven won't get hotter than about 250 degrees so it won't cook, even though all the coils burn brightly.
Anyone else encounter these symptoms or have advice?

Thanks!
