Hi.
I need to lubricate the plastic gears of the microwave turntable motor.
The motor is located at the bottom of the microwave wall.(see photo
as an example).My question is:do i need to use food grade grease or it is
okay to use,also,a non-food grade grease?
The motor is located behind the bottom wall,but it is tie to the wall
and the motor rod(which turns the glass-plate)is getting inside the micro.
So,i wonder if there could be any health concerns if i use a non-food grade grease or it is,actually,not matter at all
I am not sure if this question is appropriate to this forum,but i think that chemistry may involve here.Thanks

Do you have a link to the service and repair manual?

Hi,Billnotgatez.
I wish i have.
I couldn't find anything that related to the
type of the grease(food grade or not).

Lack of a manual for maintenance and repair could mean the company does not expect you to disassemble or do things like lubricating.  That said, it is probably prudent that if any lubricant were to be used, it would be best to be food safe.

The motor gears start to make noise and i noticed that the grease inside dry out,so i need to relublicate it.
Of course the company does not expect me to renew this part,they obviously preferes that i will buy a new motor
or even better to buy a new microwave(and every year the service becomes wrose).So,this is not
surprising that they don't make a repair manual.
Refer to the grease,I am also thinking that food grade grease is the better option,but i would like to know if it is matter at all?i mean according to the motor location,can the grease get inside the micro space(as a vapor...),since
i can't see how can it get inside from the motor as a liquid.

I can not see (my fault) if any vapors from grease (if there are any) could get inside of microwave. I am not sure the non food grade grease you intend to use has any impurities in it that may be harmful to humans (assuming it some how gets inside of microwave {how ever unlikely}).  I am not going to give advice that could come back to haunt me or the forum.

see forum rules that may apply somewhat.

If you were just using the microwave for research and not human use, I would say, probably OK.

Okay,billnotgatez,i see your point.
Thanks alot for your answer
