Lg Microwave JVM1790CK Parts

This air tunnel directs heated air from the blower assembly into the dryer drum to maintain proper airflow and drying performance. Replaces a cracked or damaged duct to restore efficient air circulation and reduce drying time variability. What it does:

• Channels warm air from the blower to the drum for consistent drying and heat distribution
• Helps maintain proper venting and prevent hot spots that can cause uneven drying
• Commonly needed when cracks, breaks, or blockages cause poor airflow or extended dry cycles
• Contributes to normal operating airflow; damaged tunnels may lead to longer run times or reduced efficiency

• Disconnect power to the appliance before beginning any repair
• Access typically requires removing the dryer's front or rear panels
• Inspect surrounding seals and fasteners; replace any broken clips or gaskets to ensure a proper seal
• If you smell burning or see significant lint buildup, clean the lint and vent system before reassembly; consider a full vent inspection

This fan assembly replaces the fan motor and blade used to move air inside the appliance, restoring proper airflow and helping the unit maintain consistent temperature and performance. What it does:

• Circulates air to support cooling or ventilation functions
• Helps prevent uneven temperatures and frost buildup in cooling compartments
• Stops unwanted noise or vibration when the motor or blade is failing
• Restores airflow when the original fan stops running or runs intermittently

• Disconnect power to the appliance before beginning any repair
• Handle the motor and blade carefully to avoid bending the blade or damaging wiring
• Basic hand tools are typically required; for model-specific steps

This wiring harness routes power and control signals between the appliance's control board and key components so electrical connections are restored and the unit can operate correctly. Installs at the control area or junction block. What it does:

• Carries power and signals between the control board and motors, valves, sensors or switches
• Re-establishes lost or damaged circuit paths that can cause component failures
• Helps fix symptoms such as no power to specific components, intermittent operation, or complete no-start conditions
• Prevents loose or corroded connections that lead to arcing or unreliable performance

• Disconnect power (unplug or flip breaker) before starting any repair
• Match connector shapes and pin counts; do not force connectors or bend pins
• Route harness clear of moving parts and heat sources; secure with original clips or ties
• Replace harness rather than splice if corrosion, damaged connectors, or burned insulation are present

Fix a microwave that won't heat or overheats with this thermostat. Essential temperature control part. Typically takes 30-45 minutes to replace.

The Door Latch Hook is an OEM replacement part for LG microwaves. Located internally on the door frame, this metal hook secures firmly into the microwave's door latch bracket when closed. As a common wear point, the hook can experience minor warping over many years of use.

Causes of a bad door latch hook include normal wear and tear, loss of tension, or deformation from frequent door opening and closing cycles long-term.

Symptoms of a bad latch hook include:

• Door that does not close fully or completely latch in place  
• Gaps forming in the door seal when shut
• Inability to achieve a tight, solid seal around the perimeter 
• Latch hook failing to grasp the bracket securely

This OEM LG part is also compatible with Sears/Kenmore microwaves.
