Panasonic Microwave Turntable Motor for NNE548WB Stock Number: ES132365
Genuine spare part for select models of Panasonic microwaves
Hello My very old NN3800 has died. First the lamp blew. Then the internal fuse in the power supply blew (spectacularly). A new fuse met the same fate immediately when attempting to heat anything. The unit momentarily tried to start and then blew the fuse. So, if I spend £25 or so (new motor, bulb & fuse) and get this going I shall be very pleased but how likely is it that the turntable motor is the problem? Also, much of the foam that forms barriers, compartments and seals within the casing has disintegrated through age. Is this a problem? Any advice gratefully received. Thanks.

The turntable motor is unlikely to be the cause of your problem and if you take off the connections and measure with a meter you would be easily able to identify a short circuit. The fault is more likely to be one of the door switches stuck or a fault with the high voltage section. We suggest due to the extremely high and dangerous voltages in microwaves you do not attempt a repair in this area.

This is the speed quoted on the label on this motor and as a mains synchronous motor it will fix to the supply frequency and keep this speed of 5 rpm on 50 hz supply and 6 rpm on 60 hz supply.
The turntable motor of my Sharp Carousel looks ALMOST identical to this one, with slightly different specifications and shorter metal drive shaft. [ 2.5 rpm / 2.5 watt - don't know what "FREE" means ] Should I take a chance it will be a suitable replacement; some others reporting here shortened the drive shaft to make it work ? On dismantling this motor it was easily apparent why/how it failed; liquid had made its way onto the very fine wire coil and burned it out. That seems to beg the question on why these motors are not made more waterproof ?

The motor should certainly do the job you require but the shaft length may prevent the drive 'hub' from sitting at the correct level and cause the turntable to be raised of the wheels. It may be possible to trim the motor shaft with a hacksaw. These motors cannot normally get water in unless large quantities of liquid is spilt or excess water when cleaning is allowed down the shaft.
The Spec looks alright AC220/240V ; 50/60Hz; 5/6rpm except the Watt- My microwave is using 2.5/2W but this is 4W.. will there be a problem ?

No the power used may be higher but the circuits will supply this without a problem.
Will this part fit my appliance?
