GE Profile Microwave Model JVM1860SF001 Is Making Noise and Smells

Thumps and Humming

• A thumping or humming noise that occurs on all power levels except the highest is the sound of the magnetron tube inside your microwave cycling on and off to achieve the lower power. The thumping comes from the magnetron tube and also may sound like a pulsating noise. Usually this is not abnormal and requires no repair.

Popping

• Food that contains a high amount of fat tends to pop as it cooks. Cover containers when heating these foods to prevent both the noise and food splattering your microwave’s interior. Leftover food spills and running the microwave while empty also causes popping noises. Using metal utensils or metal-trimmed cookware in the microwave results in electrical surges called arcs, which emit a the popping noise as well. When using the cooking probe included with your microwave, make sure it is inserted fully into the food. If the probe is not properly inserted, arcing can occur and this can damage or destroy the probe. If a hole burns through the interior of your microwave as a result of arcing the appliance may not be repairable. GE recommends replacing microwaves with holes larger than those on a screen door. If the microwave continues to pop and produce arcs, contact a repair technician.

Burnt Odors

• The smell of burnt food usually is caused by overcooked food or spills that have become baked onto the interior of your microwave. Do not use abrasive cleaners on the interior of your microwave. If the odor is present after cleaning with a mild detergent or with baking soda and water, mix 6 tbsp. of baking soda or 1/2 cup lemon juice into 1 cup of water and heat it in a microwave-save container for two to three minutes on the highest power. Leave the door open for several hours to allow air to circulate the odors out. Some odors such as fish or popcorn may require several days to disappear.

Electrical Odors

• A faint electrical odor accompanied by a very small amount of smoke is common with new microwaves. This comes from the electronic board, which cures as it is heated during the first few uses. Dust particles also can build up on the convection element and burn off. Once the dust is gone, the odor and the smoke fade. If an electrical odor is present with a popping or humming sound, contact a service technician to determine if there is short in the electrical components.
