I have a tappan stove, then oven only works part of the time. If it works one day the next day it won't. I turn it on and the electric element heats up, but won't light the gas. If i let it sit on for about 15 minutes sometimes i can light it with a piece of newspaper, however, the gas does a popping sound with hardly any coming out. Any suggestions? THANKS!!
