My Panasonic microwave oven failed the other day. The turntable had stopped doing its thing. So I took off the cover and checked the fuses and switches before deciding the unfeasibly high resistance in the turntable motor indicated its probable demise. At first glance, replacing it looked like an absolute pig of a job but I ordered a new motor online for a tenner (www.buyspares.co.uk) and felt optimistic.
When the motor arrived, I had a second look at the bottom of the microwave and realised that it had been designed to make motor replacement a snip [sic].
I used wire side cutters to snip the metal at the points indicated and the plate opened to reveal the turntable motor. Now you only need to remove two screws and it falls out. There’s no grub screw securing the motor shaft and the connections are made with spade terminals. Thanks to Panasonic’s clever design it couldn’t be easier. A couple of self tapping screws (in the snipped holes) might secure the plate better than the aluminium duct tape that I used.
In any case, the motor runs at mains voltage so make sure the appliance is unplugged before trying this at home.
