This thermostat is the temperature control switch that helps regulate your appliance's internal temperature for proper operation and food safety. It replaces a failed or faulty control to restore consistent cooling performance. What it does:

• Senses interior temperature and cycles the compressor or heating element to maintain set temperature
• Stops cooling or heating when the thermostat fails open, or causes overcooling when it fails closed
• Commonly replaced for inconsistent temperatures or an appliance that runs constantly
• Works as the user-controlled temperature regulator in the appliance's control system

• Disconnect power before starting any repair to reduce shock risk
• Handle mounting hardware and wiring carefully; note wire locations before removal
• Test operation after install by setting temperature and confirming normal cycling

A hi-limit safety switch that stops heating when temperatures get too high, protecting the appliance from overheating and helping prevent damage. Designed to replace a failed thermal cutoff to restore safe temperature control. What it does:

• Opens the heating circuit when internal temperature exceeds the safe limit to prevent overheating
• Commonly replaces a failed or intermittently opening thermal limit control
• Helps stop burners or heating elements from running unchecked when a thermostat fails
• Addresses symptoms like no heat, intermittent heating, or safety trip shutdowns

• Disconnect power before accessing heating components and wiring
• Verify the part matches the appliance diagram and wiring orientation before installation
• If corrosion or other damage is present on connectors or terminals, replace or repair per OEM guidance

The Light Bulb is an OEM part for Whirlpool ranges and ovens. It provides illumination inside the oven cavity, allowing users to monitor the cooking process without opening the oven door.

Causes of a bad light bulb can include burnout from regular use, electrical issues, or damage due to high temperatures and vibrations within the oven.  

Symptoms of a bad light bulb include:

• The light not turning on when the oven door is opened or the light switch is activated
• Flickering or dim light
• The bulb appears visibly damaged or burned out

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

This is a replacement 8-18 screw used to secure components in compatible Whirlpool appliances. It provides a reliable, corrosion-resistant fastener to restore proper fit and function for panels and internal parts. What it does:

• Secures panels, brackets, or small internal components where an 8-18 thread is specified
• Restores loose or missing fasteners that cause rattling, misalignment, or improper sealing
• Matches OEM thread size and head profile for a correct fit when listed for your model
• Prevents further wear or damage caused by using the wrong screw size

• One screw as shown

• Turn off and unplug the appliance before starting any repair
• Use the proper screwdriver or driver bit to avoid stripping the head
• Do not overtighten—tighten until snug and components seat without play
• Replace only where the OEM specifies an 8-18 screw to ensure proper fit

This is a replacement screw designed to work with a wide range of household appliances. It is used for many purposes in these appliances, from holding body panels together to securing electronics into control boards. However, screws are subject to damage through corrosion, impact, and improper installation/removal. In most cases, the primary damage to this screw is through corrosion – it may become rusted or corroded in place, depending on the appliance and the maintenance provided during its lifespan. The screw may also be stripped or rounded due to improper removal or installation. If the screw is damaged, lost, or corroded in place, it will need to be replaced. In most cases, removal will require nothing more than a Phillips head screwdriver or the appropriately sized socket with a ratchet. However, if the screw is damaged, it may require a tap set to remove it from its mounting location. Note that this is a genuine OEM replacement screw made from durable, high-quality metal, and is sold individually. It fits Whirlpool, Maytag, Roper, Estate, Amana, Crosley, and Thermador appliances. It is used in over 150 machines, ranging from washers and dryers to air conditioners.

This replacement wire provides a single insulated conductor for restoring a broken or damaged electrical connection in your appliance. It's a direct-fit service part for repairing wiring faults and re-establishing reliable power flow. What it does

• Replaces a damaged or frayed wire that can cause intermittent or no power to a component
• Restores a secure electrical connection to stop sparking, arcing, or poor contact
• Helps resolve symptoms like intermittent operation, components not receiving power, or visible wire damage
• Useful when insulation is melted, cut, or terminal ends are corroded

• One replacement wire as pictured

• Always disconnect power to the appliance before inspecting or replacing wiring
• Verify correct routing and secure with existing clips or fasteners to keep wire away from heat and moving parts
• Reuse or replace appropriate terminal connectors; ensure tight, corrosion-free connections

This fuse holder secures and connects a replaceable inline fuse to the appliance's electrical circuit, restoring overcurrent protection and helping prevent damage from short circuits or power surges. What it does:

• Holds and connects a replaceable fuse in the appliance's electrical circuit
• Completes the fuse's electrical connection so current flows through the protective element
• Replaces a cracked, burnt, or loose holder that causes intermittent power or blown fuses
• Helps restore proper overcurrent protection when the fuse itself is intact

• Disconnect power to the appliance before inspecting or replacing electrical parts.
• Inspect nearby wiring and connectors; replace any damaged components to ensure a secure connection.

This wire harness is a complete electrical connector assembly that routes power and signals between appliance components for reliable operation. It replaces damaged or frayed wiring to restore secure electrical connections and improve safety. What it does:

• Carries power and control signals between major components (motors, switches, sensors, control board).
• Replaces worn, cut, or heat-damaged wires that can cause intermittent operation or loss of function.
• Restores proper connector fit to prevent arcing or poor contacts.
• Helps address symptoms such as no power to a circuit, intermittent component operation, or blown fuses/circuit breakers.

• One complete wire harness assembly as shown.

• Disconnect power at the breaker or unplug the appliance before starting work.
• Match connector shapes and wire colors; route harness the same way as the original to avoid pinching.
• Secure with existing clips or fasteners; do not reuse damaged connectors.

This time-delay fuse protects the appliance's power circuit by opening when current exceeds a safe level while tolerating brief inrush current. Replacing a blown fuse can help restore power once the root cause is corrected. What it does:

• Protects the line and control circuits from shorts and overloads
• Time-delay design helps prevent nuisance opening during startup surges
• When open, the unit will be completely dead—no display, lights, or response
• Repeatedly opening usually indicates an unresolved electrical fault that needs diagnosis

• 1 time-delay fuse

• Disconnect power at the breaker before servicing; some appliances can retain dangerous high voltage
• Replace only with the same type and rating specified by the manufacturer
• Inspect the fuse holder and wiring for heat damage or loose connections before reassembly
• If the new fuse opens immediately, stop and diagnose the underlying cause; never bypass or upsize a fuse
