MY HOTPOINT SELF CLEANING STOVE

Question

MY STOVE IS FUELED ELECTRICALLY. ONLY ONE TOP BURNER
LIGHTS BY ITSELF. I HAVE TO MANUALLY LIGHT THE OTHER 3.
RECENTLY MY OVEN STOPPED HEATING UP THE PRE-HEAT
LIGHT COMES ON AND GENERALLY THE OVEN GOES TO 350 AND HEATS UP. MY BROILER PART WORKS.

ARE THERE PILOT LIGHTS OUT OR SOMETHING.
