Microwave Ovens (264)

Government / agencyIndexed Oct 22, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20190517-28DE3-2147380920. Severity: Incident, No Injury. Matched catalog product: Whirlpool WMH53520CS. Incident: My whirlpool over the range microwave has melted a hole on the interior rectangular plastic piece on the top of the microwave. After some research, this model was included in a recall from 2016, WMH53520CS but my serial number TR45157865 was not part of that recall. There must be something wrong with the mechanical workings of this microwave for this plastic piece to melt like it has. My fear is that if this plastic piece gets hot enough it could possibly catch fire. There is also the possibility that whatever is causing the plastic to melt is also causing additional damage that is not visible to the eye unless taken apart. I do not want to see this cause a fire because Whirlpool is making defective products. The manufactured date is Decemeber 2014.

Government / agencyIndexed Oct 16, 2026Source-linkedVerify source — SaferProducts.gov incident

SaferProducts.gov consumer incident report 20191223-793B0-2147375849. Severity: Incident, No Injury. Product: Whirlpool WMH53520CS (Whirlpool WMH53520CS 2.0 cu. ft. Over-the-Range Microwave Oven with Steam Cooking). Incident: Just over one year ago, the Whirlpool microwave WMH53520CS that was purchased was part of a bundle from Spencer's Appliance in Oct 2016, caught on fire while baking a potato. The unit was deemed out of warranty, and a countertop replacement was loaned by family until a new comparable, over the range model, could be purchased. Today while looking at a comparable unit, it was discovered that this unit was recalled, but the serial on this unit TR62593566 was out of the range of recalled units. There was a significant fire, internal to the unit, and smoke and heat damage to the surrounding cabinets. The unit is still in place, as it was when the fire occured, and can be inspected for verification that the problem occurred with the unit. We feel that the unit should be replaced by Whirlpool ]and want others to know that this problem likely impacts units outside their given serial number range.
