any idea how much will it cost ....?

small plastic door broken my landlord is chinese damn stingy and gives me a lot of trouble

Cut a piece of cardboard to size. Wrap in plastic. Tape to the top of the fridge. This is the hinge. Gravity keeps it more or less closed. You just lift it up to open.

If you don't have cardboard and plastic at home, go to Popular book shop, and buy their corrugated plastic board. No need to wrap since it is already plastic. Costs about RM5-10 for a sheet approximately A0 size (16 pieces of A4 photostat paper).

I have the plastic door also but how do i attach it?

masking tape or duct tape. The friend of every DIY handyman.

but how to do? should i call toshiba?

I doubt Toshiba do housecalls.

If you call a handyman, he's going to charge you.

If you stick it on yourself with tape, it will cost you RM0.

ok bro i will try it but making a hinge is really hard
