Parts for Ge JGB870DET3BB: Lower Oven Parts

The Temperature Sensor is an OEM part for GE ovens and ranges, accurately measures and controls the temperature within the oven cavity. This part ensures your oven heats to the desired temperature and maintains it throughout the cooking process, providing consistent and reliable cooking results.  

Causes of a bad Temperature Sensor can include exposure to extreme temperatures leading to sensor failure, physical damage, or wear and tear over time that affects its accuracy.  

Symptoms of a bad Temperature Sensor include:

• The oven not reaching the set temperature or displaying an error code related to temperature regulation.
• Unpredictable oven temperatures, leading to inconsistent cooking results.
• The oven taking longer than usual to preheat, or not heating at all, indicating that the sensor is not properly gauging and adjusting the temperature.

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

This small replacement bumper cushions and protects the appliance frame/trim where panels meet, helping reduce vibration, chipping and rattles for a cleaner, quieter fit. Ideal when the original bumper is worn, cracked or missing. What it does:

The Bottom Oven and Deflector Assembly is an OEM part for GE ranges. This assembly features both the bottom oven cavity and heat shield deflector above it. It allows for simultaneous cooking on two racks while protecting cabinets from excessive heat. 

The deflector assembly works to direct warm air out from the bottom oven opening. It distributes heat evenly and prevents issues caused by concentrated airflow. Over time, cooking residue buildup may occur on these parts or cracks could form due to repeated heating.

Symptoms of a bad bottom oven and deflector assembly include:

• Excessive cabinet warming from bottom oven use  
• Uneven cooking results within the bottom oven cavity
• Difficult air circulation or hot spots occurring 

This authentic GE replacement restores like-new cooking performance. Featuring durable manufacturing and a premium fit, it maintains oven functionality for more efficient meal preparation.
 

The Bottom Oven and Deflector Assembly is an OEM replacement part for GE wall ovens/ranges. It contains both the lower cooking cavity and heat deflector plate.

Causes of needing replacement can include damage from accidental drops or spills inside the lower oven, failure of the sealed door gasket allowing moisture, or accumulation of baked-on grease harming reflectivity.

Symptoms of issues with the bottom oven assembly include:

• Inefficient or uneven cooking/baking in the lower cavity
• Improper heat distribution and browning on foods
• Difficulty maintaining set oven temperatures
• Visible cracks or gaps in the oven cavity walls or door

This OEM GE part is also compatible with Hotpoint, RCA, and some Kenmore models.

This oven deflector is a stamped heat shield that helps direct oven heat away from sensitive components for more even cooking and to protect the back wall and wiring. Fits in the oven cavity where heat needs to be redirected. What it does:

This is a replacement screw that can be used with many different types of household appliances. Screws fasten various pieces of machines together. They can also help to reduce the amount of vibration in the machine. If a screw is missing or damaged, it could cause a machine to stop working properly, or to vibrate more than it should.The screws are made from metal and will typically last for a long time. However, the threads and other parts of the screw can wear down with use. The screws could also become lost when making other repairs to the appliance. Replacement of the screws is generally easy, but it will depend on where it is placed.This item can replace certain screws found in various models of ranges, ovens, dryers, and microwaves from General Electric, Hotpoint, Whirlpool, and Kenmore. This is a genuine OEM replacement part sourced from the manufacturer. It is sold individually. Owners may want to have several replacements on hand in case they need them.

Replacement fan blade that mounts to the motor shaft to circulate air inside the appliance, restoring airflow and reducing vibration or noise from damaged or bent blades. Works with the fan motor to help maintain proper cooling and ventilation. What it does:

• Spins on the motor shaft to move air through the appliance's cabinet or evaporator area.
• Restores even airflow for more consistent cooling and performance.
• Reduces excessive noise and vibration caused by cracked, warped, or missing blades.
• Helps prevent airflow-related issues such as warm spots or slow cooling when the fan is not operating properly.

• Disconnect power to the appliance before servicing to avoid electric shock or injury.
• Remove interior panels or housing to access the fan; handle the blade carefully — edges can be sharp.
• Slide the blade onto the motor shaft and secure per OEM method (set screw, clip, or hub); ensure proper alignment and rotation direction.
• Test fan operation after installation and reassemble panels securely.

Back

This motor drives the oven's convection fan to circulate hot air for even, consistent baking and roasting. Replace a noisy or stalled motor to restore proper airflow and uniform temperatures throughout the cavity.

• Spins the convection fan to move heated air across all racks
• Helps reduce hot and cold spots for more even cooking results
• Failure signs include the fan not running, running slowly, or making loud humming/grinding/squealing noises
• Symptoms can include uneven baking/roasting, longer preheat times, and poor browning

• Disconnect power at the breaker before servicing
• Access varies by model; remove appropriate panels to reach the motor and fan
• Transfer the existing fan blade and any reusable mounting hardware if your model uses separate parts
• After installation, ensure the blade spins freely and clears the shroud before restoring power

This is a genuine OEM replacement nut that is used on convection oven fans. This nut holds the fan onto the spindle. If the nut becomes lost during repairs to the fan, it will need to be replaced before the fan will work. This nut locks the fan to the spindle to turn and move the air around inside the oven. The fan helps the food to cook more evenly and reduces areas in the oven that are not cool enough or hot enough. If the fan is not working, the convection oven will not cook correctly.Convection ovens are different from regular ovens, and the fan is part of the reason. Convection ovens use the fan and an exhaust system to move the heat around inside the oven to cook food more evenly and faster. Many convection ovens have a setting that allows the oven to be used as a regular oven. If the nut is missing and the fan is inoperable, the oven can be used for regular cooking if it has this feature. Otherwise, the convection oven should not be used until the nut is replaced.This nut is a silver metal replacement part that is sold individually. It is designed for use in convection ovens made by GE and Kenmore.

This receiver hinge is the metal bracket that secures a refrigerator or freezer door hinge pin and helps the door open and close smoothly. It replaces worn or damaged receiver brackets to restore proper door alignment and operation. What it does:

• Restores smooth opening and closing when the original bracket is cracked or worn
• Helps maintain an effective door seal by keeping the door properly aligned

• One receiver hinge bracket

• Disconnect power to the appliance before beginning any repair
• Typically installed at the cabinet hinge location; basic hand tools required
• Support the door while removing/installing the hinge to prevent injury or damage
