Lmv2257 Parts

This temperature-sensing safety switch monitors heat inside the microwave and opens or closes its circuit at a set point. Replacing a failed thermostat helps protect the unit from overheating and restores proper fan or heating control. What it does:

• Monitors surface temperature where it is mounted (cavity, duct, or component)
• Opens/closes its electrical circuit at a specific threshold to prevent overheating
• Can interrupt power to heating components or signal the exhaust fan, depending on design
• Symptoms can include: unit shuts off until it cools, runs but won't heat, exhaust fan won't auto-cycle or runs constantly

• Unplug the microwave; if over-the-range, remove it safely from the cabinet
• Discharge the high-voltage capacitor before servicing
• Note wire positions and transfer one lead at a time; ensure tight connections
• Mount firmly and flush to the original location/bracket for proper thermal contact

A high-voltage capacitor for the appliance's high-voltage circuit that stores and releases electrical energy to support proper heating operation. Replacing a failing capacitor can restore consistent heating and prevent related electrical faults. What it does:

• Stores and delivers high-voltage energy used by the magnetron/ high-voltage assembly to generate heat.
• Failure may cause no-heat or weak-heat conditions in the oven.
• Faulty capacitors can contribute to arcing, loud humming, or blown high-voltage fuses.
• Works as part of the HV circuit; not a user-serviceable low-voltage control.

• High-voltage components can hold a dangerous charge—disconnect power and discharge the capacitor before servicing.
• Use insulated tools and avoid touching terminals; verify proper operation with appropriate test equipment.

The TEMPLATE is an OEM part for LG microwaves. It is the outer casing and control panel covering that defines the microwave's design and aesthetics.  

The causes of a bad template can include cracks, dents, or damage to the outer surface from impacts or normal wear over time. Heat and humidity fluctuations can also cause template materials to degrade.

Symptoms of a bad template include:

• Cracks or breaks in the template material
• Loose, misaligned, or damaged control panel or display  
• Yellowing, warping, or discoloration of plastics
• Openings or gaps that compromise the microwave structure

This genuine OEM LG replacement part restores the microwave's appearance and protects internal components. It is also compatible with some Kenmore and Sears microwaves

• Start threads by hand to avoid cross-threading, then tighten snugly with the correct driver
• Do not overtighten to prevent stripping threads or cracking plastic bosses

The Transformer is an OEM part for LG microwaves. It is responsible for stepping down high voltage current from the wall outlet to safe low voltage used by the microwave's electronic control system. Located inside the microwave cabinet beneath the turntable mechanism, the transformer supplies precise power to crucial components including the magnetron, control console, and touch controls.

Causes of a transformer failing include stresses from constant heating and electromagnetic flux over many years, damage from water damage, or manufacturing defects.  

Symptoms of a bad transformer include:

• Microwave failing to heat or function 
• Faulty or unresponsive control panel and display
• Buzzing or humming noises emanating from inside

This genuine LG replacement ensures all electronic systems receive stabilized power safely. Compatible with Sears/Kenmore branded microwaves using LG components.
