Parts for Whirlpool EV181NZTQ03: 04 - Unit Parts

The Evaporator Motor is an OEM part for Whirlpool refrigerators. This part circulates air over the evaporator coils, ensuring even cooling throughout the refrigerator and freezer compartments.

Causes of a bad evaporator motor can include wear and tear from prolonged use, electrical faults, or physical damage to the motor components.  

Symptoms of a bad evaporator motor include:

• Unusual noises coming from the refrigerator
• Inconsistent or insufficient cooling
• Frost buildup in the freezer
• Refrigerator running continuously or not running at all

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

This heater wire harness connects the dishwasher's heating element to the unit's electrical system. Replacing a burned or brittle harness restores safe, consistent power delivery so the element can heat properly during wash and dry portions of the cycle.

• Routes power from the main wiring to the heater terminals
• Ensures secure, high-temperature connections at the element
• Damage can cause no heat, poor drying results, or intermittent heating
• Visual clues include melted/browned connectors or loose terminals at the heater

• Disconnect power at the breaker before servicing
• Access the heater connections from the bottom/front of the unit and note wire routing
• Transfer one lead at a time; fully seat terminals and keep wiring clear of hot or moving parts
• Inspect heater studs for pitting/discoloration; replace the element if terminals are damaged or the connector shows severe overheating

This oven door gasket creates a tight seal between the oven cavity and door to help maintain consistent cooking temperatures and improve energy efficiency. It replaces a worn or torn seal to reduce heat loss and prevent smoke or odors from escaping. What it does

• Seals the oven door to help keep heat inside the oven cavity during cooking
• Helps maintain even cooking temperatures and improves energy efficiency
• Reduces heat, smoke and odors escaping into the kitchen when the oven is in use
• Restores a close-fitting door closure if the old gasket is cracked, flattened or missing

• One oven door gasket as shown

• High-level replacement: usually stretches into a channel or secures with clips; follow your model's service instructions
• Ensure the oven is completely cool and disconnected from power before attempting replacement
• Inspect the door and channel for debris or damage and clean prior to installing the new gasket

This bimetal defrost thermostat mounts on the freezer evaporator tubing and monitors coil temperature to control the defrost heater. Replacing a failed thermostat restores proper defrosting, reduces frost buildup, and helps maintain stable refrigerator and freezer temperatures.

• Monitors evaporator temperature and opens the circuit to end the defrost cycle once ice has melted
• Closes when sufficiently cold so the defrost heater can energize during the next cycle
• Acts as a safety limit to help prevent overheating during defrost
• Typical symptoms: heavy frost on the back wall/evaporator, refrigerator section too warm, unit not defrosting, or defrost heater not energizing

• Disconnect power before servicing; wear cut-resistant gloves
• Remove freezer bins/shelves and back panel to access the evaporator; melt excess ice as needed (do not pry on coils)
• Install the thermostat firmly against the evaporator tubing using the existing clip/bracket if applicable; match wire connections and routing
• Reassemble panels, restore power, and verify normal operation

A small rubber grommet that cushions and protects wiring or hoses where they pass through sheet metal or plastic openings. Replaces a worn or damaged grommet to help prevent chafing and reduce vibration-related noise. What it does

• Cushions and protects wires, hoses, or tubing from sharp edges
• Helps prevent abrasion that can cause fraying or electrical shorts
• Reduces vibration and rattling where components pass through panels
• Commonly replaced when the original shows cracking, tearing, or visible wear

• One rubber grommet

• Disconnect power before accessing internal wiring or panels
• Remove the damaged grommet and press the replacement into the opening until fully seated
• Use blunt tools or a cloth to avoid cutting or distorting the new grommet

This PTC motor start relay provides the temporary start circuit needed for the motor to spin up, restoring normal starting on appliances with a failed start relay. Simple replacement for appliances that won't start or hum at power-up. What it does

• Supplies a temporary current path to the motor's start winding during startup.
• Drops out once the motor reaches running speed so the motor operates on its run winding.
• Commonly used when an appliance won't start, hums but won't spin, or has intermittent start problems.
• Works with the motor and start circuitry; does not include a motor or harness.

• Disconnect power before servicing to avoid shock or injury.
• Access usually requires removing an access panel—keep track of screws and mounting hardware.
• Replace with the exact part number shown on your appliance or parts list; ensure correct orientation and secure connections.

This terminal cover protects the appliance's power connection area, keeping wiring and terminals enclosed to reduce shock and short risks. It's a direct-replacement trim piece that restores the factory protective barrier around the terminal block. What it does:

• Covers and shields the terminal block where the power cord connects, helping prevent accidental contact.
• Helps reduce the risk of shorting or arcing at exposed power connections.
• Addresses symptoms like visible exposed terminals, loose or unprotected wiring at the power entry area, or a missing/broken cover.
• Restores the appliance's intended safety enclosure after repair or shipping damage.

• One terminal cover

• Always disconnect all power (unplug or shut off breaker) before accessing the terminal block.
• Remove the old cover and position the replacement over the terminal area so mounting holes align; secure with the original screw(s).
• Inspect terminal screws and wiring for tightness and damage while cover is off; do not attempt electrical repairs.
• If terminals or wiring are damaged, replace or repair those components before reinstalling the cover.

This evaporator block is a molded insulation piece that helps direct airflow and limit frost build-up around the evaporator in refrigerator freezers. Replacing a damaged or missing block restores proper airflow paths and helps maintain consistent cooling. What it does:

• Fits around the evaporator to insulate and channel cold air through the correct passages.
• Limits excessive frost accumulation on the evaporator coil by closing unwanted gaps.
• Helps maintain even temperatures in the freezer compartment for reliable cooling.
• Can reduce cycling issues and improve overall fridge performance when original insulation is compromised.

• One evaporator insulation block

• Disconnect power to the appliance before servicing to avoid shock.
• Defrost and remove accumulated ice from the evaporator area before installing the new block.
• Remove evaporator cover/panels as needed; handle the block gently to avoid tearing molded foam.
• Reassemble panels and restore power; check for proper airflow and ice/frost levels after a full defrost cycle.
