General Electric Microwave DVM1850DM2BB No heat

The High Voltage Diode is an OEM part for GE microwaves. This high-voltage diode is crucial for converting alternating current (AC) to direct current (DC), enabling the magnetron to generate the microwave energy needed for cooking. 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.

You should replace the diode-H.V assembly if it becomes faulty due to electrical issues, wear and tear, or physical damage. Continuous exposure to high voltage can cause the diode to deteriorate over time, leading to malfunction.

Symptoms of a bad diode-H.V assembly include:

• The microwave not heating food
• A burning smell or unusual noises during operation
• The microwave shutting off unexpectedly
• Visible damage or burn marks on the diode

This GE replacement part is also compatible with Hotpoint, RCA, and some 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.

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

The Magnetron is an OEM part for GE microwaves. The magnetron converts electrical energy into microwave radiation, which heats and cooks the food placed inside the microwave oven.

Over time, the magnetron can wear out or fail due to regular use, electrical surges, or overheating. A malfunctioning magnetron can lead to the microwave not heating properly, reducing its overall functionality and efficiency.

Symptoms of a bad magnetron include:

• The microwave not heating food at all
• Unusual noises such as buzzing or humming during operation
• A burning smell or visible damage inside the microwave
• The microwave turning on but failing to heat

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

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.
