This terminal block cover protects the appliance's electrical connection area from accidental contact and debris, helping reduce the risk of shorts and corrosion while keeping wiring secure and contained. What it does:

• Covers and shields the power terminal/block where the power cord connects
• Helps prevent accidental contact with live terminals and reduces short risk
• Keeps out dust, lint and debris that can cause corrosion or arcing
• Useful when the original cover is cracked, missing or showing burn marks

• Always disconnect power (unplug or switch off breaker) before servicing electrical components
• Typically installs over the terminal block and secures with the existing fastener(s); inspect mounting hardware for wear
• Replace if cracked, melted or if terminals are exposed; ensure cover seats fully before restoring power

The Relay and Overload Kit is an OEM replacement part for Whirlpool refrigerators. It is an essential component of the refrigerator's electrical control system, responsible for powering components and protecting circuits from overload.

Symptoms of a bad relay and overload kit are:

• Refrigerator not cooling or icing 
• Components like lights or fans not working
• Buzzing or humming noises from the electrical control area
• Repeated blown fuses 

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

This compressor mounting grommet kit replaces worn or damaged rubber mounts that secure the compressor and reduce vibration. Restoring proper mounts helps cut down on compressor noise and prevents movement-related wear. What it does:

• Cushions and isolates the compressor to reduce vibration and rattling noise
• Keeps the compressor secured to its mounting bracket during operation
• Helps prevent stress and wear on mounting hardware and tubing
• Addresses symptoms like excessive vibration, banging, or unusual compressor noise

• Disconnect power to the appliance before beginning any repairs
• Support the compressor while removing and installing mounts to prevent strain or shifting
• Use appropriate hand tools and avoid over-tightening fasteners that can compress or damage grommets

The Axle is an OEM part for Whirlpool refrigerators. This axle allows it to be easily repositioned or moved for cleaning and maintenance. It supports the rollers that enable the refrigerator to glide across the floor.

Common causes of a bad axle include prolonged use, excessive weight, or impact damage, which can lead to the axle bending or breaking.

Symptoms of a bad refrigerator roller axle include:

• Difficulty moving the refrigerator
• Uneven or wobbling movement
• Scratches or damage to the floor
• The refrigerator not staying level

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

This kit is used to mount evaporator trays on compressors.

This refrigerator compressor circulates refrigerant to cool the appliance and restore proper temperatures. Replaces a failed compressor to help the refrigerator maintain set temperatures when the cooling system is compromised. What it does:

• Pumps refrigerant through the sealed cooling system to enable heat exchange and cooling.
• Runs the refrigeration cycle so the refrigerator and freezer can reach and hold target temperatures.
• Common symptom linkage: fridge not cooling, compressor humming or not running, or frequent cycling.
• Can cause system pressure issues if damaged or leaking.

• One compressor (single sealed unit)

• Power should be disconnected before beginning work and the refrigerant must be recovered per regulations.
• System evacuation, leak testing, and proper recharge with the correct refrigerant are necessary after replacement.
• May require replacement of mounting hardware, start device, or filter-drier—verify system condition during service.

This wire assembly connects the capacitor to the appliance's motor or control, restoring a secure electrical path for reliable start/run operation. Replaces a damaged or worn harness to help resolve starting and intermittent power issues. What it does:

• Provides insulated wiring and terminals to link the capacitor to the motor or control
• Ensures a secure electrical connection for proper start/run signaling
• Can resolve symptoms such as failure to start, humming or intermittent motor starting
• Prevents shorts or arcing from frayed or damaged wiring when functioning correctly

• Always disconnect power at the breaker or unplug the appliance before servicing
• Capacitors can hold a dangerous charge — have the capacitor safely discharged before disconnecting wires
• Match connectors and routing to the original harness; secure wires away from moving parts and heat sources

Condenser fan motor mounting bracket assembly.

The condenser fan motor is an OEM part for Whirlpool refrigerators. It plays a vital role in circulating refrigerant through the condenser coils, facilitating heat exchange and maintaining the refrigerator's cooling efficiency.

Over time, the motor-condenser can wear out or fail due to electrical issues, mechanical wear, or blockages in the condenser system. A malfunctioning motor can compromise the refrigerator's cooling performance, leading to temperature fluctuations and increased energy consumption.

Symptoms of a bad Motor-Condenser include:

• The refrigerator not cooling properly
• Unusual noises coming from the back of the refrigerator
• The compressor running continuously
• Increased energy bills due to inefficient operation
• Overheating of the refrigerator
