Microwave/Convection OTR JVM1190 002
fan sound is almost a whirr; I changed the belt but the sound is still not "normal". ?? problem- stirrer??
Hello, and thank you for using this service. I'll be helping you with your problem today.

So probably the best thing to determine which part is creating the sound is to just unplug the stirrer motor or unplug the turntable motor, or unplug the cooling fan motor. I'm not there to actually hear what noise you are experiencing, but if you unplug these parts and the noise goes away, then you know that this is the culprit. See if there is anything that the part is rubbing on to create the noise and if it looks all good, replace the part.

I'm not comfortable unplugging motors since I'm not sure of the wiring. There is no turntable. When I initially changed the "rubber band" belt, the sound was what I was used to. After a short time it became a lower decibel sound that seemed not to run normally. Sorry I can't identify the sound better. I'm concerned of the safety of running the appliance as is. The microwave does heat. I've not tried using the convection feature.

So the problem with not knowing exactly what is causing the noise is that it really has a number of possibilities that can cause the problem. If the noise is related to the belt and sitter motor and you replaced the belt but it's making the noise again, I'd replace the stirrer motor itself next.

Thanks. I appreciate your prompt response. This appliance is 14 years old so I'm questioning how much repair should be done versus replacing the appliance. Is the stirrer motor a usual problem occurring over time?

It is something that fails as the unit gets older because it's one of the few moving parts inside the unit. I would just set a cut off on a unit this old and if parts start to exceed $100 or so maybe it's time to replace the unit. Convection units are not all that cheap.

I just heated some veggies and the sound I hear is like something is running but not accomplishing anything. The veggies were heated, but I wonder if this might be what I could expect if the stirrer motor was not working properly and moving the microwaves around. I can see the fan on the right side, and it does move I think normally. There is no way I can observe the stirrer as the door must be closed. Any other thoughts?

Not really. You can't visually see most of the parts move which is why you would just need to leave them unplugged. But if the stirrer motor isn't moving right it won't really cause a noticeable affect.

Thanks again for your help. Guess I'll need to make some decisions on using it as is for a time, and look at repair versus replace.
