Alfredo for Model Number GE JVM3670SK04 My microwave-circa 2008 new with house purchased stopped operating earlier this month. Here are some details taking place prior to the microwave tripping the dedicated circuit breaker: - Within 5 seconds of the microwave programmed to heat, a loud growling-type noise could be heard, followed by the microwave power shutting down, tripping the circuit breaker. This was re-constructed three times. - Once power was restored, the date could be re-set using the control panel, the timer would continue to operate, and both the downlight (to light a separate gas range-unattached from the microwave and the fan could still operate. Further note that the microwave's capacitor did not exhibit any sign of being deformed. When following the installation of the magnetron and re-starting a heating cycle for under 5 seconds, I did detect a slight burning odor at which point I immediately shut off the heating cycle. The source of any kind of burning could not be readily established as the odor immediately dissipated. I did buy from Appliance Parts Pros and have installed a magnetron, but the same initial problem persists. Are there any recommendations on what else to change out? Would you recommend I continue to attempt a repair, given the situation as I described it? If a repair would be performed, what would be the sequence of replacement parts inserted and sequentially tested by initiating a brief test microwave heating sequence? There are a number of reasons why I'd like to repair the microwave that has been extremely reliable over the las 12 years, mainly that today's appliances don't have the durability of older models (trend to a casual disposable culture?) Earlier in December, 2019, I had occasion to repair parts to my highly reliable 12-year old LG Steam Clothes Washer, after its door hinge was no longer operating (determined to be caused by severe corrosion to its tension springs). The hinge change, along with installing a new rubber door seal and detergent/softener/bleach drawer have it operating as good as new. Many thanks for having the parts available! Your feedback is greatly appreciated on my microwave issue.
Answer Hello Alfredo, since you replaced the magnetron tube and did not mention any further growling noise just a burning odor, I would suggest you check the inner walls of the waveguide. If the magnetron had arced to the waveguide it would have damaged itself resulting in the growling noise, consequently, if there are any arc marks or scorch marks on the waveguide inner walls then the waveguide is damaged and it is not a replaceable part. The microwave cannot be repaired. Read More... Answered by AppliancePartsPros.com | Monday, January 20, 2020
