Smeg sa35mx microwave vibration noise when in use

Excessive 60 cycle hum/vibration means a bad Magnetron. Time to replace the unit.

Remove cabinet cover and observe what's going on.

Yes, the door switches are not working correctly.
I would get it replaced.

In all likelihood the mangnetron has failed, or perhaps even the Power Supply. or a fault that is shutting the system down for safety reasons You need to have it serviced by a reputable service centre/man. Ensure you get a firm "Quote" before proceeding, and remember these days the cost of repair can equal or exceed the price of a new one.

Call GE answer center 1-800-626-2000 ask for tech help, Have your Model # orr your data plate ready.

I have looked and I can't find one either. You can mail Smeg in the UK at [email protected] They may be able to point you in the right direction.

Hi there,

Thanks for the quick reply. As you said this has been mounted into a recess and surrounded like a picture frame.

I found some screws are very deep inside the recess and it has been obstructed by the grille/frame.

If you have any pics or any illustration, can you please forward it to me.

Thanks

I would recommend you visit Smeg Service spares.

Manufacturers used to include access panels in the rear or side so you could easily change the bulb. That exposed the customer to line voltages, and that posed a real liability threat, so they stopped using them.

You now must generally remove the outer cover to replace the bulb.

In many over-the-range models, that can mean having to take the oven down from the wall! For safety's sake, that should be a two-person job and it's really helpful if you have your original installation instructions to do this.

Many models use halogen lamps. You must not touch the new one with your bare skin as the oils will shorten the bulb life.

if it makes a loud humming sound it is something in the high voltage circuit. it could also be a bad microswitch in the door latch assembly
