Parts for Thermador CMT-19 SERVICE CODE H & UP: 05 - Base Parts

This discharge adapter connects the appliance's drain hose to the drain or pump outlet, restoring a secure path for wastewater and preventing leaks. Fits the factory connection point to ensure correct hose alignment and sealing. What it does:

• Provides a sealed connection between the appliance drain/pump outlet and the drain hose
• Prevents leaks and water dripping at the hose connection
• Helps restore proper drainage when the original adapter is cracked, worn, or missing
• Matches OEM connection dimensions to maintain proper hose routing and fit

• Disconnect power to the appliance and turn off water supply before starting
• Inspect hose and clamps; replace clamps or hose if damaged for a reliable seal
• Push adapter fully onto the outlet and secure hose with a clamp 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 3/8 in. cable clamp secures wiring and small hoses to the appliance chassis to prevent chafing and keep connections tidy. It's a simple replacement that restores proper routing and strain relief. What it does:

• Holds a single cable or small hose in place to reduce movement and wear
• Prevents wiring from rubbing against sharp edges or vibrating loose
• Helps maintain safe, organized internal routing for better reliability
• Commonly used where a compact clamp is needed for 3/8 in. diameter cables

• One 3/8 in. cable clamp

• Inspect surrounding wiring and routing before installing; replace any damaged wires or insulation
• Install in the same location and orientation as the original; secure firmly but avoid over-tightening
• Disconnect power to the appliance before servicing to reduce shock risk
• Use basic hand tools; no special tools required for most installations

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 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 magnetron shroud is the protective cover that surrounds the microwave's magnetron, helping direct cooling airflow and shielding the high-voltage assembly from debris. Replacing a damaged shroud restores proper protection and airflow to the magnetron. What it does:

• Protects the magnetron and nearby components from dust, food debris, and accidental contact
• Helps direct cooling air around the magnetron to prevent localized overheating
• Reduces the risk of arcing or electrical shorts caused by debris contacting the magnetron
• Be replaced if cracked, warped, corroded, or missing hardware that prevents a secure fit

• Always unplug the appliance and discharge the microwave capacitor before servicing — microwave high-voltage components are dangerous.
• Remove outer cabinet panels and any shielding to access the magnetron area.
• Inspect mounting tabs and surrounding components; reuse OEM fasteners or replace as needed for a secure fit.
• If you see arcing, burning, or magnetron damage, replace the magnetron and related components per OEM guidance.
