Thomas M Coarsegold , CA September 04, 2016 Upper broil coils were bad Ordered parts and replaced--works great now. Needed screwdrivers and a 3/8 air impact to get screws loose. Had to wrap plastic ties to keep wires from falling thru holes so I could rehook new coils. Rear holddowns removeable to put on new coils. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
