Many operating parts are replaceable on an Emerson brand microwave. Emerson microwave owners can find small replacement parts such as switches, fuses, couplers and lamps. Various sizes of Emerson glass cooking trays are available for purchase. Many Emerson parts that break or become damaged can be found online.
Important parts that help Emerson microwaves function can be replaced. For instance, a single magnetron part sold by Repair Clinic is a replacement part that works in numerous Emerson microwave models. Sometimes it is helpful to look at a diagram of different microwave components to find a specific part needed. Sears Parts Direct sells Emerson microwave parts with corresponding diagrams. If a control panel needs fixing, the diagram for this component depicts each part separately.
Common problems that can lead to a microwave needing repair include the microwave failing to turn on, sparks erupting after turning it on and lack of heat. When a microwave fails to turn on, it may be due to a blown fuse or damaged door switch. Food splatter can cause sparks to fly inside a microwave. Sparks can also be caused by a malfunctioning microwave stirrer, which requires the replacement of either the fan motor or stirrer belt. If the microwave fails to heat and makes a buzzing noise, this is an indication that the capacitor or magnetron may be defective.
