oven stopped heating

I thought I was being a total girl and was afraid of fixing my oven myself, but when it took forever to get my landlord to come over and fix my oven I ordered the part, got it in three days, followed the directions online and fixed it myself! Easy, easy! Turned off the electric, switched off the gas, unscrewed 2 bolts, unplugged the old switch, screwed in the new switch, replugged it and turned on the stove. Roasted a chicken and baked bread within minutes!
