A list of GE product recalls is available on the GE Appliances website, which indicates that, as of 2015, there has been a micro-oven combo recall which took place in 2007. However, there have been no recalls for any stand-alone microwave oven units.
A micro-oven combo is a wall oven with a built-in microwave. The recall is due to some incidences in which the door switch in the microwave overheated and caused a fire hazard. GE advises that consumers should not use the microwave component unless a technician repairs the unit, but states that the lower oven is still safe to use. GE offers either a free repair or a rebate to consumers who own the affected product models.
