Hi there,
New to this forum but search and couldn’t find something matching my problem with a Whirlpool Microwave (AMW 415 IX).
I recently moved in a house where the built-in microwave (probably around 5 year old) is tripping the RCD – the reason why the previous owners had a spare microwave on the side…
I realised that it’s only tripping when the door is closed (doesn’t when door is open).
I tested the outlet with another device, it works; I tested the microwave on another outlet, same problem.
I took out the microwave, removed the cover to inspect the switches (3 of them – 1 on top and 2 bottom) triggering when the door is closed. All seem in contact and ‘click’ when pressed on.
Nothing looking burnt on the boards.
I’m a bit lost and don’t have the equipment to test where the potential short circuit may be…
I was thinking of buying parts to replace the switches, since they click, I’m not sure that’s the best option, but can’t think of anything else. (http://m.buyspares.co.uk/microswitch/pr … =2031123bs)
I guess my question is: is it possible that one or more micro switch may be damaged even though clicking? Or is there something else I should be looking into?
Also, I may call in a professional, but I guess that will set me back at least £100, so may end up buying new…
Thanks!
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
you are tripping the RCD so your looking for an earth fault so I would try
disconnect turntable motor, insulate wires and see if it still trips with it not connected
also inspect the infra red grill elements for signs of breakage
its unlikely to be the switches

Thanks! Saved me ordering the switches! I’ll try that tonight and will let you know.
If lucky, is it okay to operate the microwave without the failing part(s) keeping the disconnected wires insulated with duck tape?
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
if its the grill element ok no probs but use good quality insulation tape
if its the turntable motor then unit will work but food may cook unevenly also do not operate it with the motor removed as it may leak microwaves

Semi victory –
I tried disconnecting the grill element, still tripping. Also tried disconnecting the light (even though seemed to be working), still tripping.
I can’t access the turntable mechanism and motor, but when disconnecting its connection directly from the micro-switch of the door mechanism, tada! It doesn’t trip anymore.
Last question(s)… is it safe to operate the microwave leaving this disconnected (and insulated with duck tape)? Does it just mean I’ve only lost the turntable functionality?
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
Thanks Dave – just saw your last post.
The motor is definitely staying in as I can’t access and I’ll duck tape the wire end now disconnected from the micro-switch.
Sounds good?
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
And thank you so much for your advice and pointing me in the right direction!
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
on most microwaves you have to clip out the lugs holding the cover, then fix the motor, then the cover is made to clip back on using a screw

Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
I don’t know if it looks different because it’s a built-in, but it seems like I need to remove a few part to access it.
I think I’ll go with the ‘no turntable’ option!
Thanks again.
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
without a turntable all foods that you cook will need to be turned whilst cooking to prevent localised hot spots in the food. liquids are not affected as the liquid can mover to disperse the heat
if you want to replace it take a picture of the bottom of the oven and post it and I will point out what to doDave
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
Yes! I got it… Thanks for offering further help!
I had no choice because with the turntable disconnected from the switch: did a test run (with light food in the microwave), I could hear short ‘tick tick tick tick’ then after about 5 seconds of running, the cook stopped. Timer stopped (didn’t trip anything or blow any fuse – yet?). It could be resumed, and then stopped again.
I guess disconnecting the turntable from the switch puts more (?) power onto some other element and makes it stop…
So, should I change the motor then – https://www.partmaster.co.uk/whirlpool/ … ref=549973
(Annoyingly, some people who bought the part commented and managed to figure it out and changing it in 20min! I definitely missed the trick here…but challenged me to find out).
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
open the base. disconnect both wires to the motor and insulate.
then check microwave works fully before proceeding
motor part number
old number 481236158419
new number C00311611
you can search for both numbers and you could ask site shop to see if they can supply
Dave
Re: Microwave Whirlpool AMW 415 IX tripping RCD when door cl
And… fixed!
Part received, replaced and microwave now working fine.
Thanks again for your help Dave.
