Parts for Thermador CMT-231: 04 - Power & Related Parts

This relay mounting bracket secures a relay or control module inside the appliance, keeping electrical components stable and aligned for reliable operation. It replaces a worn or damaged bracket to restore proper component positioning. What it does:

• Holds the relay or control module firmly in place to prevent movement and vibration
• Helps maintain correct contact alignment for reliable switching
• Can reduce relay-related noises such as rattling or buzzing when the bracket is loose
• Supports safe routing and separation of nearby wiring and components

• Disconnect power to the appliance before starting any repair
• Installation typically requires removing an access panel and existing bracket hardware
• Keep original screws and mounting hardware; replace only the bracket unless other parts are damaged

This plenum assembly routes airflow and seals ventilation passages for proper operation and quiet performance. It replaces a damaged or cracked plenum to restore correct airflow and reduce leaks or abnormal noises. What it does:

• Channels and directs airflow through the appliance's ducting
• Seals gaps to prevent air leaks that can reduce performance
• Helps reduce rattling or whistling caused by a broken or loose plenum
• Supports attached components and maintains proper fit of adjoining parts

• Disconnect power and follow all safety instructions before beginning work
• Inspect mounting tabs and seals during install; replace damaged fasteners or gaskets as needed
• Verify fit and airflow after installation; do not force or modify the part

This resistor bracket secures the appliance's resistor/CMT assembly, keeping electrical components mounted and stable for reliable operation. It replaces a worn or broken bracket to restore proper component positioning and minimize contact issues. What it does:

• Provides a secure mounting point for the resistor/CMT assembly
• Keeps wiring and resistor components properly spaced to prevent contact or shorting
• Helps maintain consistent electrical connections that affect operation
• A damaged or missing bracket can lead to intermittent component function or failure symptoms

• Disconnect power to the appliance before servicing to avoid electrical shock
• Inspect surrounding wiring and fasteners; replace any damaged clips or screws as needed
• Handle bracket edges carefully; some replacements may have sharp edges
• Verify fit with your model's parts diagram—do not modify the bracket during installation

This metal relay mounting bracket secures a control relay to the appliance chassis to keep the relay stable and aligned. It prevents relay movement and reduces stress on electrical connections for more reliable operation. What it does:

• Provides a secure mounting point for a control relay so terminals and wiring stay stationary
• Reduces vibration and movement that can cause intermittent connections or relay noise
• Helps maintain correct relay alignment for consistent electrical contact
• Commonly used where a relay must be fastened to a metal chassis or frame

• One relay mounting bracket

• Disconnect power to the appliance before starting any work to avoid shock or injury
• Remove access panels as needed to reach the relay location; retain all fasteners for reassembly
• Use the existing screws or mounting hardware; do not overtighten to avoid stripping threads or stressing the relay
• Inspect surrounding wiring and connector condition while accessing the relay; replace damaged wiring or connectors as needed

This terminal block provides a secure connection point for appliance wiring, restoring safe electrical continuity and helping prevent loose or intermittent power at the connection. Designed to match original OEM fit and function. What it does:

• Secures and organizes incoming and internal wiring at a single connection point
• Provides a stable electrical connection to prevent arcing or intermittent power
• Replaces damaged, cracked, or corroded terminal mounts that cause intermittent operation
• Restores factory routing and strain relief for attached wires

• One terminal block

• Disconnect power before servicing to avoid shock or injury
• Verify wire placement and tightness of screws; replace any frayed or damaged wires
• Inspect surrounding insulation and mounting hardware; reuse original screws if undamaged

This is a #8-32 x 1/4-inch pan-head screw with red zinc finish used to secure appliance panels and small components. It replaces deteriorated or missing fasteners to restore proper fit and reduce rattling or loose parts. What it does:

• Fastens trim, panels, brackets, and small assemblies where a #8-32 x 1/4 pan-head screw is specified
• Provides corrosion-resistant holding with a red zinc finish for long-term fit
• Stops loose or vibrating panels and helps maintain proper alignment
• Matches OEM thread size and head style for correct seating in threaded holes

• Screw

• Disconnect power to the appliance before servicing to avoid electrical hazards
• Use a #1 Phillips driver sized to the screw head; apply steady pressure to prevent cam-out
• Tighten until snug—do not over-torque to avoid stripping threads or damaging parts
• If threads are damaged, replace the mating insert or stud per manufacturer guidance

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.

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
