halacha - Microwave on Pesach


A friend told me that his family will kasher his microwave in general (ie if non-kosher food was heated up in it) but will not kasher it for Pesach, letting it lie dormant instead. Does anyone have a source for such a distinction? (Let's also assume the tray can be covered, so the issue is only with the microwave itself.)


I know people are generally overly machmir (stringent) when it comes to chametz. I'm looking for a source for this particular distinction.



Answer



You wanted to know, why some people might be machmir on this:


From InstituteforDayanim.com



Kashering a microwave for Pesach is impossible since only metal or wood can be kashered for Pesach. Although one can kasher plastic the rest of the year, one should not do so for Pesach. The inside of a microwave is generally not metal and is thus not kasherable.



It goes on to give a method to test if the microwave has absorbed any ta'am (even lifgam), and if it hasn't, it says it may be used. However, this that it can't be kashered, and that the only way to use it is if you're sure it hasn't absorbed anything, may be why some are machmir.





From teach613.org



Although many people will not kasher a microwave for Pesach because it has plastic components and because it is hard to clean properly, if you choose to kasher it the process is as follows. ...



(Plastic can not be kashered for Pesach.)
