Bryan, thanks for your prompt reply. The Model number is XXXXX The service plus parts costs may show that it would be cheaper to buy a new one that having this one repair. Could you give me in addition to the cost of the magnetron the estimated repair cost.
Bryan, I wish to apologize for not replying to you sooner. I did follow your advice and considered not fixing it myself. The part was $72 but not having the corresponding equipment to check for proper settings, I dropped the idea. I bought a new GE microwave, which is the same size as the Whirlpool, for what I believe is less than it would have cost me to have it repair. The cost of the new was $200. Thanks for the help.
