Parts for Ge JEM21K01: 01 - Section1 Parts

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 high-voltage rectifier diode is used in the microwave's high-voltage circuit. It converts AC to DC so the magnetron can produce heat. A failed diode can cause no heat, loud humming, or a blown fuse when starting. What it does:

• Rectifies high-voltage AC to DC to power the magnetron
• Blocks reverse voltage in the HV circuit
• Common failure symptoms can include: runs but doesn't heat; loud hum then shutdown; line fuse blows at startup

• 1 high-voltage diode

• Unplug the microwave and properly discharge the high-voltage capacitor before servicing—dangerous voltage can remain even when unplugged
• Match diode orientation/polarity to the original and ensure a solid chassis ground connection where used
• Route leads and reinstall any clamps/insulators exactly as found; keep wiring clear of sharp edges and hot components
• If the original diode failed, inspect the HV capacitor and transformer for related issues before reassembly

The Microwave Door Switch is an OEM part for GE microwaves, designed to prevent the microwave from operating when the door is open by interrupting the power whenever the door is not securely closed. The door switch is an essential safety feature.

Symptoms of a failing Microwave Door Switch include:

• The microwave not starting or heating
• Running when the door is opened
• Unusual noises when the door is closed  

Causes of a bad Microwave Door Switch can result from repeated opening and closing of the door or slamming that can cause the switch to degrade or become misaligned, leading to intermittent or failure.

This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances.

This small replacement cushion pads the oven lamp cover to prevent vibration and keep the glass cover seated securely. It restores a snug fit so the lamp cover doesn't rattle or shift during oven use. What it does:

• Cushions and centers the oven lamp cover to reduce rattling and vibration
• Helps keep the lamp cover properly seated and aligned with the housing
• Protects the lamp glass from direct contact with metal edges
• Can be used if the original cushion is torn, missing, or hardened

• One oven lamp cover cushion

• Disconnect power to the appliance before servicing; allow the oven to cool completely
• Remove the lamp cover and replace the worn or missing cushion, then re-seat the cover
• Handle the lamp glass carefully to avoid breakage; wear gloves and eye protection
• If the cover or lamp assembly is cracked or damaged, replace the damaged components rather than relying solely on the cushion

Ceramic

A small keyed retaining spring that secures and tensions moving components to restore proper engagement and alignment. Replaces a worn or missing spring to help stop loose parts and intermittent engagement. What it does:

• Holds keyed components or shafts in place to maintain proper alignment and operation
• Provides tension for reliable engagement of latches or moving parts
• Helps eliminate play, rattling, or intermittent contact caused by a broken or missing spring
• Used where a compact, keyed retaining spring is required for secure fit

• Disconnect power before beginning any repair to avoid shock or injury
• Verify correct orientation and seating of the keyed end before tightening or reassembling
• Use basic hand tools; avoid forcing parts—if it won't seat easily, recheck alignment
