Parts for Kenmore 911.4942990 (9114942990, 911 4942990): Microwave Body Parts

This replacement cushion is a small rubber/foam bumper that cushions moving parts and reduces vibration and noise for a quieter, smoother appliance operation. It helps prevent metal-on-metal contact and wear where installed. What it does:

• Absorbs shock and vibration to protect panels, doors, or components
• Dampens noise caused by moving or rattling parts
• Prevents direct metal-to-metal contact and cosmetic wear
• Helps maintain proper alignment of the part it cushions

• Disconnect power to the appliance before beginning any work
• Typically press-fits into a mounting hole or snaps into place; no special tools usually required
• Inspect mating surfaces for damage or debris and clean before installing

This microwave high-voltage capacitor stores and releases energy in the high-voltage circuit to power the magnetron. Replacing a failed capacitor helps restore proper heating and protects other components in the high-voltage system.

• Works with the transformer and high-voltage diode to supply the magnetron with the required voltage
• Failure may result in the unit running but not heating
• Shorted capacitors can blow the internal fuse or trip a breaker; opens may cause loud humming or buzzing
• Visible swelling or leakage on the capacitor body are common failure signs

• Unplug the microwave; capacitors can retain a dangerous charge even when unplugged—discharge using an appropriate, insulated method before servicing
• Note wire positions and terminal orientation; transfer any mounting hardware from the original part
• Mount securely and route wires to avoid pinching

This magnetron generates microwave energy to heat food in compatible countertop and over-the-range microwaves. Replacing a worn magnetron restores cooking power and helps eliminate uneven heating or failure to heat. What it does:

• Converts high-voltage electrical power into microwave radiation used to cook and reheat food
• Common symptom: oven runs but food doesn't heat or heats very slowly
• May also be needed if you notice loud buzzing, arcing, or burning odors during operation
• Works with the microwave's high-voltage system; other components may also need inspection

• One magnetron (single unit as shown)

• Disconnect power and discharge the microwave's high-voltage capacitor before servicing
• Inspect surrounding parts (waveguide, diode, capacitor, and cooling fan) for damage during replacement
• Use only the correct replacement part number to ensure proper fit and safe operation

This is a replacement mounting screw used to secure panels and components on compatible appliances. It restores proper fit and prevents rattling or loose parts for a safe, stable appliance. What it does:

• Secures panels, trim, brackets or small components in place
• Replaces missing or stripped fasteners that cause rattling or loose parts
• Helps maintain appliance alignment and safe operation when installed properly
• Small fastener for interior or exterior appliance assemblies

• Disconnect power (and gas if applicable) before servicing the appliance
• Use the correct screwdriver and hand-start threads to avoid cross-threading
• Do not overtighten; snug until secure to prevent stripping or damaging parts

Black. 8-18 AB HXW 3/8

This lower trim clip secures the appliance's lower trim or kickplate, keeping panels aligned and preventing rattles or gaps. It's a small but essential fastener for a finished, stable exterior. What it does:

• Holds the lower trim or kickplate in place to keep the front panel aligned
• Prevents trim from sagging, rattling, or separating from the cabinet
• Restores a secure fit after a broken or worn clip
• Works behind the trim to keep visible edges flush for a clean appearance

• The lower trim clip shown

• Disconnect power to the appliance before starting work to avoid electrical hazards
• Access the clip by removing the lower trim or kickplate per your model's service instructions
• Use appropriate hand tools and gentle pressure to avoid cracking trim pieces
• Replace any damaged clips with matching parts; inspect surrounding fasteners for wear
