Parts for Thermador MTR30: Other Parts

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 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 part has been discontinued by the manufacturer and is no longer available.

A replacement spring hinge that helps support and counterbalance the appliance door for smooth opening and closing and proper alignment. Restores reliable door movement and reduces drop or slamming when the original spring is worn or broken. What it does:

• Provides counterbalance tension to help hold the door open and control closing motion
• Restores proper door alignment and prevents uneven closing or gaps
• Reduces sudden drops, slamming, or heavy-feeling doors caused by a weak or broken spring
• Works as the mechanical tension element within the hinge assembly to maintain normal door operation

• One spring hinge (single counterbalance spring)

• Install with power disconnected and door supported to prevent dropping or injury
• May require partial door removal or hinge access depending on appliance design
• Compare the new spring to the old part for correct orientation before installing
• If other hinge components show wear or damage, replace them at the same time for best performance
