Federal safety regulators are hoping the fourth time is the charm for millions of recalled dehumidifiers that have now been linked to 450 fires and more than $19 million in property damage: Gree Electric Appliances — the manufacturer fined a record $15.45 million over the fiery dehumidifiers earlier this year — has re-announced the recall. The Consumer Product Safety Commission, along with Gree, re-announced the recall — which covers nearly 2.5 million dehumidifiers — Tuesday aiming to get more consumers to replace their defective, and dangerous, machines.
