My fault, Im an idiot

[mbskye]

I was an idiot last year when my heat went out and used my Frigidaire fgf353bawl gas range for heat for about a week. At the end of the week the oven still kinda worked but wont heat up over 100 deg ( sometimes a little more, sometimes a little less ) trying to trouble shoot and fix it before thanksgiving. cook top/ burners still work fine. Any help would be greatly appreciated.
