Thermador Cmt-21 Parts

This Bake Element is an OEM part for Bosch Ovens. It's responsible for providing heat in the oven cavity for baking and cooking purposes. With prolonged use, the bake element can wear out or malfunction.

Frequent use at high temperatures can cause the bake element to deteriorate over time. Physical damage or overheating may also contribute to its failure.

Symptoms of a Bad Bake Element:

• Uneven cooking or baking
• Inconsistent oven temperatures
• Oven takes longer to preheat

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

This door switch detects when the door is fully closed and latched. Replacing a worn or stuck switch restores safe, consistent start/stop behavior and ensures the unit only runs with the door securely shut. What it does:

• Senses door position and signals the control to enable/disable operation
• Prevents the appliance from running with the door open
• Resolves issues such as: won't start despite power, stops when the door is jostled, "close door" message, or needing to press on the door to run
• Helps restore reliable cycle start and proper safety interlock function

• 1 door switch

• Disconnect power at the breaker before servicing
• Access the switch behind the door panel or latch area; note wire locations or take a photo
• Move wire connectors to the new switch one at a time; ensure terminals are fully seated
• Reassemble and test door closure and operation before returning to service

Size; 8-18 x 1/2 inch.

A replacement glass turntable plate that restores a microwave's rotating cooking surface for even heating and stable cookware support. Fits on the drive roller to provide a flat, heat-safe surface for daily microwave use. What it does:

• Replaces a cracked, chipped or missing glass turntable so food heats more evenly
• Provides a stable surface for plates and bowls to rotate during cooking
• Works with the turntable roller and coupling to restore proper rotation
• Prevents wobble and scraping that can occur with damaged glass

• Unplug the microwave or disconnect power before installing
• Handle the glass carefully to avoid cuts; do not install if chipped or cracked
• Align plate on the center drive coupling/roller support; it seats and rotates freely
• Use only the exact OEM plate size and part number to ensure proper fit

This LIS switch (CMT) is a direct-replacement electrical switch that restores reliable circuit signaling for the appliance control system, helping return proper operation to affected functions. Designed to fit the original mounting and connector layout. What it does:

• Acts as the LIS (logic/interlock/signal) switch that opens or closes an electrical circuit when actuated.
• Restores reliable communication between the door/control assembly and the appliance control board.
• Commonly used to address symptoms such as intermittent operation, failure to start, or unresponsive controls.
• Matches OEM form and connector style for a straightforward replacement.

• Disconnect power (unplug or switch off breaker) before attempting any repair.
• Use basic hand tools; note connector orientation before removal to ensure correct reinstallation.
• Handle the switch and wiring harness carefully to avoid damage to terminals or insulation.

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 mounting bracket secures a dishwasher component to the cabinet or chassis, restoring proper panel alignment and reducing movement. It's a simple replacement for a bent, broken, or missing bracket to improve fit and quiet operation. What it does:

• Provides a secure mounting point for door/panel or internal components
• Keeps panels and trim aligned to prevent gaps and rubbing
• Reduces rattling or movement caused by a loose or damaged bracket
• Restores stable attachment after impact or corrosion-related failure

• Disconnect power and turn off the water supply before starting work
• Basic hand tools (screwdriver, nut driver) are typically required
• Support the panel or component while removing and installing the bracket to prevent dropping
• If fasteners are corroded or damaged, replace them with like-for-like hardware

This lock bolt spring is a small replacement spring for the door latch assembly that helps the lock bolt return and hold the door closed. Restores reliable door latching and proper engagement of the door lock mechanism. What it does:

• Provides tension for the lock bolt so the door latch returns to the closed position
• Helps the door stay securely latched during operation
• Can resolve symptoms like a loose or non-returning latch, door not staying closed, or intermittent door-lock issues
• Works as part of the latch/lock assembly — not a standalone electronic lock

• One lock bolt spring

• Disconnect power to the appliance before beginning any repair
• Small parts and springs can be under tension; use care and keep track of orientation
• Installation typically requires partial disassembly of the door or latch housing;

This inner door glass panel replaces the interior glass pane in the door assembly. It restores a clear, heat-resistant barrier so your appliance can retain heat and operate safely after the original pane cracks or shatters.

• Serves as the interior glass pane of the door facing the cavity
• Helps insulate the cavity to maintain stable cooking temperatures
• Direct replacement for cracked, shattered, or missing inner glass
• Can help address heat loss and unsafe door conditions

• Disconnect power at the breaker and allow the appliance to cool completely before starting
• Remove the door per your model's service instructions and place it on a padded work surface
• Wear cut-resistant gloves and eye protection; handle glass by the edges
• Transfer any brackets/clips in the original order and tighten fasteners snugly without overtightening

This wire oven rack slides into the oven's side supports to hold cookware at the correct height. Replace a bent, rusted, or missing rack to restore safe, level support and smooth sliding for baking, roasting, and broiling. What it does:

• Provides a stable, level surface for pans and dishes on the oven's side rails
• Lets you position food at multiple heights for proper cooking and airflow
• Slides in and out for easy loading and unloading when properly seated
• Common replacement reasons: bent/warped wires, flaking finish or rust, rough sliding, or poor fit

• 1 oven rack

• Allow the oven to cool completely; wear gloves to avoid sharp edges
• Pull the old rack straight out; clear debris from the side rails
• Align the new rack with the side supports and slide it in; ensure stops face the back if present
• Ensure the rack is evenly seated on both rails before placing cookware

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.
