Thermador Microwave Parts

This microwave turntable ring (also called a roller ring) sits beneath the glass tray and uses small wheels to support smooth, even rotation. Replacing a worn or cracked ring restores stable tray movement and more consistent heating.

• Supports the glass turntable and guides it as it rotates for even cooking
• Helps resolve issues like the tray not turning, jerky or noisy rotation, wobbling, or uneven heating
• Replaces a damaged, warped, or missing roller ring to keep the tray level

• Unplug the appliance before servicing
• Remove the glass tray and lift out the old ring
• Clean the cavity floor; set the new ring (rollers down) centered on the track
• Reinstall the tray, ensure it seats on the drive, and test rotation before heating food

The Cooking Tray is an OEM part for Bosch microwaves. As the centerpiece of the microwave, the cooking tray ensures even cooking by rotating food items during the cooking cycle. It supports dishes and rotates continuously to evenly distribute microwave energy throughout recipes.

Causes of a bad cooking tray can include wear and tear due to extended use over time. Food splatter or spills left inside the microwave may damage or corrode the tray. Accidental dropping or cracking of heavier dishes placed on the tray can also cause issues.

Symptoms of a bad cooking tray include:

• The tray not spinning or rotating properly during cooking
• Unevenly or partially cooked food
• Loud grinding or scraping noises coming from the tray
• Cracks or breaks visible in the plastic surface

This genuine OEM Bosch part is also compatible with Thermador, Gaggenau and select Kenmore models.

This diode is a small rectifier used on the appliance control electronics to allow current to flow in one direction, protecting the board and enabling proper control signals. Replacing a failed diode restores correct circuit behavior. What it does:

• Provides one-way current flow on the control board to prevent reverse voltage
• Protects sensitive electronics from backfeed and voltage spikes
• Can prevent control errors caused by a shorted or open diode
• Commonly replaced when control circuits fail to power or behave intermittently

• Disconnect power to the appliance before accessing controls to avoid shock
• Handle circuit boards and components with ESD care; avoid touching traces and contacts

This microwave high-voltage capacitor replaces the internal capacitor that stores and supplies the pulse of energy needed for the magnetron to generate microwaves. Restores proper HV circuit operation when the capacitor is faulty. What it does:

• Stores and releases high-voltage energy used by the microwave's magnetron
• Commonly fails after electrical stress, age, or arcing
• Symptoms of a failing capacitor: microwave not heating, intermittent operation, humming or arcing noises, or blown fuses
• Works with the high-voltage circuitry—do not use as a general-purpose capacitor

• Disconnect power and unplug the appliance before any service.
• Capacitors can retain dangerous voltage even when unplugged—discharge safely using an insulated discharge tool.
• Follow the appliance service manual for correct removal and wiring; replace with the exact OEM part.

This switch assembly replaces a faulty E34 - 19HV switch to restore proper electrical control in the appliance. It provides the same fit and function as the original to help re-enable the affected control circuit safely. What it does:

• Acts as the electrical switch that completes or breaks a circuit when engaged
• Restores normal operation when a failed switch causes intermittent or no response
• Commonly associated with control failures, unresponsive buttons, or power-related symptoms
• Matches OEM form and mounting to fit into the original switch location

• Always disconnect power to the appliance before servicing
• Handle wiring and connectors carefully; note wire locations or take a photo before removal

This thermal fuse stops excessive heat build-up by opening the circuit when temperatures get unsafe, protecting the appliance and its heating components. Replace a failed fuse to restore normal heating and safety functions. What it does

• Opens the circuit if overheating is detected to prevent damage or fire risk.
• Prevents the heating element or motor from running when the fuse is blown.
• Common symptom: appliance fails to heat or runs but produces no heat.
• Common symptom: appliance does not start or suddenly stops during a heat cycle.

• One thermal fuse.

• Disconnect power to the appliance before servicing to avoid shock or injury.
• Replace with the exact OEM part number; improper substitutes may cause malfunction or safety issues.
• Inspect surrounding wiring and heating components for faults that could cause repeated fuse failures.

This is a replacement LIS CMT switch used to restore proper electrical switching for the control module and motor circuits. It helps return normal operation when the original switch is worn or failed. What it does:

• Acts as an electrical switch for the control module and motor circuitry
• Enables the appliance to complete control signals needed for motor or control functions
• Commonly linked to symptoms like no motor response, intermittent operation, or unresponsive controls
• Provides a direct replacement that fits the original mounting and connector arrangement

• Disconnect power to the appliance before attempting any repairs to avoid shock
• Handle the switch and connectors carefully to avoid damage to terminals or wiring
• Verify connector orientation and secure mounting when installing the new switch

This replacement capacitor with internal resistor helps stabilize control circuits and assist motor start in compatible appliances, restoring reliable electrical performance and preventing intermittent operation. What it does

• Provides the capacitance needed for motor start/run and helps suppress electrical noise in control circuits.
• Supports steady voltage during startup to reduce motor humming or failure to start.
• Can resolve intermittent operation, erratic control behavior, or startup delays when failing.
• Contains an internal bleed/resistor to safely discharge stored energy and reduce residual charge risk.

• Disconnect power at the breaker and unplug the appliance before accessing electrical components.
• Capacitors can hold a charge — discharge safely and use insulated tools.
• Handle carefully to avoid damage from bending leads or crushing the housing.
