The Goldstar and Comfort-Aire dehumidifier brands were first recalled in 2009 after four serious fires. Since then, there have been 16 more reports of smoke, fire and arcing associated with the dehumidifiers.
In all, 98,000 dehumidifiers are now being recalled.
The consumer product safety commission says the power connector for the machine's compressor can short-circuit, which poses a serious fire and burn hazard.
The dehumidifiers are believed to have caused more than $1 million in property damage. No injuries have been reported.
