The amount of heat rejected from a refrigerator is minimal and doesn't usually run long enough for a full dryer cycle. Dryers also need max CFM air flow and ducting the fridge into the dryer might be a net loss in and of itself. My fridge 150 watts and runs for 10-15 mins at a time. Dryer has an element in it that produces 33x more heat than the refrigerator when it is switched on.

Your gains will be very minimal in theory but if you are ducting your air flow through the dryer outside the small period of fridge operation, you'll likely be doing damage to the refrigerator efficiency. I can't see a worthwhile net gain here and see plenty of flaws in the effort. Might help if this is all timed for the recovery of a defrost cycle though, that's a good 30 minutes of runtime while cooling off a hot freezer coil and using higher compressor amperage.
