blades keep falling off condenser fan

hey all! so i have a condenser fan that the blades keep spinning completely off the rod that comes out of the fan motor.

i have a guy coming to fix the issues, but my question is… over the next or two is it okay to keep the refrigerator plugged in without the fan running (i’ll just leave the blades off)?

i’m worried about it getting really hot without any air circulation next to the compressor and being potentially dangerous.

any recommendations?
