Switching off refrigerator for 6 months or so

Yes no problem but don’t keep any food in refrigerator..

Switch off.

Clear all the items, wipe clean the internals, slightly leave the door open for air flow

If its a non frost free refrigerator, make sure you remove all the water/ice. Wipe off any residual water/moisture with a dry cloth/sponge. Anything wet will create fungus.
You can keep something like camphor/cinnamon sticks/etc inside the refrigerator to obfuscate any malodor that may gather during the time. Keep the door open a little.

Completely dry the fridge without any moisture inside and then you can leave it for months, nothing will happen.

Same scenario came to me and I did the same and now it is working fine even after 6 months

Thanks for all the inputs..
this is in Kerala and its too humid these days with too much rainfalls and heat.

is it ok if I wipe the entire fridge dry , leave it open for 2 days – to make sure excess moisture dries away, and keep some cinnamon sticks and silica, and leave the door closed ?

even if it smells, will it go away ?

this should be the best choice considering humid conditions
