General Electric Microwave ZSC2001CSS Won't start or doesn't start

This microwave thermostat monitors the internal temperature and automatically shuts off the microwave when it reaches 105 degrees Celsius to prevent overheating. It protects your microwave from damage caused by excessive heat buildup. Replace this part if your microwave shuts off unexpectedly during normal operation or if it overheats frequently.

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.
