General Electric Microwave JVM1870SK03 No heat

The High Voltage Diode is an OEM Replacement Part that acts as a one-way gate for electrical current on GE microwaves. It allows power to flow in a single direction. This part is critical in regulating the electrical current within the device it is used in. Measuring approximately 3-1/2" in length, this diode features a banded side with a #8 ring terminal and a non-banded side with a 1/4" female quick connect.

Unlike most electrical components, this diode does not read continuity, instead, it reads resistance. It's crucial to note that a functioning diode will only show resistance in one direction. If it exhibits this characteristic, the diode is in good working condition. This diode is compatible with select GE, Hotpoint, and Kenmore models.

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.

Replacing a defective microwave door switch is crucial for maintaining the safety, functionality, and efficiency of your GE microwave, ensuring it operates correctly and safely with each use. This OEM GE part can also be used on Hotpoint, RCA, and Kenmore/Sears appliances. 
 

The GE magnetron is an OEM replacement part responsible for generating the microwave energy that heats and cooks your food. Located within the microwave's cooking chamber, typically behind the control panel and connected to the waveguide, the magnetron emits high-frequency microwaves, which are then distributed throughout the cooking cavity. This electromagnetic radiation excites water molecules in the food, causing them to heat up and cook the food quickly and efficiently.

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

This part fixes the following symptoms

• Failure to heat or uneven heating of food
• Humming or buzzing noises
• Tripped circuit breakers when using the microwave

The Monitor Switch is an OEM replacement part for GE microwave ovens. Located internally on the turntable control circuit board, this switch monitors rotation of the turntable during cooking cycles.  

Causes of failure involve degradation of the electrical contacts from continuous arcing loads over years of use combined with vibration stresses.

Symptoms of a faulty monitor switch include:

• The turntable no longer rotates or spinning intermittently
• Cooking cycles aborting prematurely with error messages 
• Screeching or grinding noises emanating from beneath cavity
• Visible burnt spots on turntable drive assembly

This genuine GE switch is also compatible with select Hotpoint and RCA models.
