A broken or defective ignitor can prevent your oven from functioning correctly. It can cause your food to be cooked inefficiently, or it can cause your oven not to heat up at all. Both of which, are not welcome in the kitchen, especially for anyone who values the use of their kitchen appliances. Fortunately, it is possible to replace a broken or defective Frigidaire range ignitor, but unless you are already knowledgeable about appliance maintenance, we usually recommend leaving this type of repair to a trained appliance professional.
