Parts for Lg LMH1017CVST: Base Plate Parts

This 4.0x16mm tapping screw secures trim and internal components on compatible appliances, providing a reliable fastener for repair or reassembly. Use the correct screw to maintain fit and function during service. What it does:

• Fastens appliance panels, brackets, and small components where a self-tapping thread is required
• Replaces stripped or missing screws that cause loose panels or rattling
• Helps restore proper alignment and secure electrical or mechanical parts
• Suitable where a 4.0 x 16mm size and tapping/sharp thread are specified

• One 4.0x16mm tapping screw (quantity: 1)

• Use the matching screw location and thread engagement; do not force a misaligned fastener
• Tighten until seated; avoid over-torquing which can strip threads or crack plastic
• Disconnect power and follow appliance safety procedures before servicing
• If screws repeatedly strip, inspect mating threads or use an approved repair insert

A Tap-Tite binding-head screw used to fasten appliance panels and components where a self-tapping metal thread is required. Replaces missing or damaged fasteners to restore secure assembly and reduce vibration or rattling. What it does:

• Creates its own mating thread in thin sheet metal for a secure hold without a nut.
• Holds panels, brackets, and trim in place to prevent looseness or movement.
• Commonly used where stripped, missing, or broken screws cause rattling, misalignment, or parts that won't stay attached.
• Compatible with standard screwdrivers or nut drivers sized to the binding-head.

• Disconnect power and unplug the appliance before working on it.
• Use the correct driver bit to avoid cam-out or head damage.
• Start straight and apply steady pressure; avoid overtightening to prevent stripping the formed threads.
• If the original hole is badly damaged, assess for repair or use of a larger fastener as needed.

Thermistor is a temperature-sensing replacement that monitors refrigerator and freezer temperatures so the control board can regulate cooling. Replacing a faulty thermistor restores accurate temperature readings and helps stabilize cooling performance. What it does:

• Senses interior/evaporator temperature and sends a signal to the control board for temperature regulation.
• Helps prevent erratic cooling, long run-times, or inconsistent compartment temperatures when operating correctly.
• Faulty thermistors can contribute to excessive frost, failed defrost cycles, or compressor cycling issues.
• Use when the existing sensor fails to report correct temperatures or the part number matches.

• Always disconnect power to the appliance before servicing to avoid shock or damage.
• The sensor is typically mounted on or near the evaporator or inside a cabinet wall; access may require removing panels or covers.
• Handle the sensor and wiring harness gently; avoid pulling on wires or bending the sensor element.

This high-voltage transformer steps household AC up to the level the magnetron needs to generate microwave energy. Replace a failing transformer to restore reliable heating when the unit runs but food remains cold.

• Steps up line voltage to the high voltage required by the magnetron
• Works with the high-voltage capacitor and diode to create microwave energy
• Failure can cause running but no heat, loud humming/buzzing, burning odor, or visible overheating
• Shorted windings can blow the internal fuse or trip a breaker

• Unplug the microwave; high-voltage components can retain a dangerous charge—properly discharge the HV capacitor.
• Remove the outer cabinet, label wire locations, and disconnect leads carefully. Transfer any mounting hardware/brackets and secure the transformer firmly.
• Verify all connections are tight and routed correctly; reassemble and test with a cup of water. Do not operate the microwave empty.
