Symptoms of a bad microwave switch:

• Difficulty in selecting or changing settings
• Microwave not responding to button presses or inputs
• Erratic behavior, such as randomly changing settings or modes
• Complete failure of the microwave to operate or power on

This OEM Bosch part is also compatible with Thermador, Gaggenau, and some Kenmore microwave models.

The Support is an OEM part for Bosch microwaves. It is designed to hold and stabilize internal components within the microwave, ensuring they remain securely in place during operation for safe and efficient performance.

Over time, the support can become worn out or damaged due to continuous use, exposure to heat, or accidental impacts. Causes of a bad support include cracking, warping, or general weakening of the material, which can compromise the stability of internal parts.

Symptoms of a bad support include:

• Loose or misaligned components inside the microwave
• Unusual noises or vibrations during operation
• Poor performance or uneven heating due to misaligned parts

A compromised interlock support can lead to the microwave not functioning properly or running when the door is open, which is a significant safety hazard.

Symptoms of a bad door interlock support include:

• The microwave not starting or stopping unexpectedly
• Error messages indicating a door issue
• The microwave running when the door is open
• Visible damage or wear to the interlock support
