General Electric Microwave EMO3000CSS001 No heat

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 is a monitor or interlock switch that detects whether the microwave door is properly closed before allowing the unit to operate. It is a safety device that shuts off microwave power if the door is open or if other door switches malfunction. Replace this switch if the microwave does not start, runs with the door open, or blows a fuse when the door is closed.

Microwave not heating or humming loudly? The high-voltage diode converts AC to DC for the magnetron. Repair takes 30-45 minutes with basic tools.
