Question about Kenmore 66469 / 66462 / 66464 Microwave Oven

Microwave runs constantly

We have a Kenmore microwave oven (model # 721.62463200) that recently started running continuously (without heating up) when the door is closed. It only stops running when the door is opened or when it is unplugged. The microwave is about 1 year old. Any suggestions for what this might be would be greatly appreciated. Thanks!

If it's less than a year old, it's under warranty and you should call the nearest Sears store for free repairs. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk You can find helpful exploded view diagrams and order parts by entering your full model number here: http://www3.sears.com (the 3 is correct)

Usually that is a sign that your magnetron tube has gone bad (shorted out).

Kenmore elite mircowave model 721,62369201...has a F9 error. ?? The unit runs, but does not heat up.

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Constant rattling noise during operation

possibly the "stirrer" motor - this is in the top and turns a metal reflecting ring to disperse the microwaves around the oven more evenly. About $70 on GE site for my oven.
