Product review (4 stars): Save money over calling for repair service.
I bought this kit before the one in the dryer goes bad because I want to be sure I have the parts on hand when the heating coil does fail. Repair parts often run out of stock and I want to insure that when the time comes I can do the repair rather than having to replace the dryer. Over time the heating coil becomes thinner and thinner thus reducing the effectiveness and requiring longer drying times and costing you more in electricity consumption.  I've bought Firgidaire products in the past and have been very happy with them. Many off brand products are inferior and are a poor fit. I would recommend buying such items at the first sign of ware even if you don't replace them before they fail. As they say, An ounce of prevention is worth a pound of cure
