Parts for Maytag DNF20J: 03 - Unit Compartment & System Parts

Refrigerator not cooling or running constantly? The compressor circulates refrigerant to maintain temperature. This repair requires refrigerant handling.

Start relay for refrigerator compressors that helps the compressor begin running at power-up. Replacing a failed relay can restore normal starting behavior and resolve common startup symptoms. What it does

• Provides the initial start current path to the compressor during startup.
• Allows the compressor to reach running speed, then drops out once the motor is running.
• Common symptoms a bad relay may cause: compressor clicking, humming without starting, intermittent cooling or frequent cycling.
• Installed as the electrical component used only on compatible compressor assemblies.

• Disconnect power to the appliance before servicing to avoid electrical shock.
• Access the relay at the compressor; remove and replace the relay only after confirming diagnostics.
• Dispose of the old electrical part per local regulations.

Fix a refrigerator that clicks but won't start or runs warm. This compressor start relay restores reliable startup. Simple DIY repair in under an hour.

Refrigerator clicking but not cooling? A failed overload protector can prevent the compressor from running. Simple plug-in replacement part.

Refrigerator not cooling or stops running after a few days? This compressor overload protector prevents motor damage from overheating. Easy 15-minute fix.

This overload is a thermal protection device that mounts on the motor/compressor and opens the circuit when excessive heat or current is detected. Replacing a weak or failed overload helps restore safe startup and protects the windings from damage. What it does:

• Monitors motor/compressor temperature and current draw
• Interrupts power on overheat/overload to prevent damage
• Aids troubleshooting of start/run issues when paired with the start device
• Common symptoms: hums then clicks off, won't start, intermittent shutdown, frequent tripping

• 1 thermal overload protector

• Disconnect power before servicing; allow components to cool
• Access the terminal area on the motor/compressor; remove any cover
• Note/photograph wire positions; transfer wires and fully seat the new overload on the correct terminal
• Inspect the start relay, capacitor, and terminals for heat damage; replace any compromised parts

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 Run Capacitor is an OEM part for Whirlpool appliances, designed to provide the necessary electrical charge to start and run the compressor motor. This part attaches to the compressor to aids in maintaining a consistent motor speed and ensuring smooth operation. The run capacitor plays a crucial role in the appliance's electrical system, storing and releasing energy as needed to power the motor.

Causes of a bad Run Capacitor include electrical surges, wear and tear over time, or overheating, which can lead to a failure in providing the necessary start-up energy or maintaining motor speed.

Symptoms of a bad Run Capacitor include:

• The appliance does not start.
• The motor shuts off shortly after starting.
• The appliance is humming but not running.
• Increased energy consumption.

This OEM Whirlpool part can also be used on Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore/Sears brand appliances.

Replace a faulty heat exchanger if water is freezing in the drain tube during defrost cycles. Compatible with various freezer and refrigerator models.

Refrigerator not cooling properly? A clogged filter drier prevents proper refrigerant flow. Requires professional installation due to sealed system.

Fix a freezer that won't cool or has frost buildup with this evaporator coil. Requires soldering skills and heat shield for installation.

Fix frost buildup and warm temps in your freezer with a new defrost timer. Restores automatic defrost cycles. Straightforward DIY repair.

Fix ice buildup in your freezer with this defrost heater. Replaces burnt-out heating elements on evaporator coils. Moderately difficult, 2-5 hour repair.

Fix ice buildup and cooling issues with a new defrost thermostat. This bi-metal switch monitors evaporator temperature to prevent frost accumulation.

Replacement mounting screw for securing panels, brackets, and components inside your appliance. Needed when original screws are stripped, lost, or damaged.

Motor mounting bracket for freezers. Secures the motor assembly in place. Replace if cracked, broken, or causing motor misalignment or vibration.

Protective shield that covers and guards the motor assembly in your freezer. Replace if the original is cracked, broken, or missing to protect components.

Replacement fastener screw for appliances. Secures panels, trim, clips, and components. Needed when original screws are stripped, missing, or damaged.

Replacement mounting screw for freezers and refrigerators. Secures internal components and panels. Order a new screw if original is stripped or missing.

This replacement screw secures specified refrigerator components—such as covers, brackets, and internal panels—so they stay properly mounted. Replace a missing, stripped, or corroded fastener to restore a tight, rattle-free fit and reliable operation.

• Provides the correct fastener for locations identified in your model's parts diagram
• Helps prevent looseness, vibration, and rattling of panels or brackets
• Replace if the head is stripped, threads are worn, or the screw is missing
• Symptoms can include loose parts, gaps, or noises from movement

• Unplug the refrigerator and shut off water if working near the ice maker or dispenser
• Match length and type to the original; follow your model's parts diagram for placement
• Start threads by hand to avoid cross-threading; tighten snugly without over-torquing, especially into plastic
• Keep track of screw positions; do not mix different screw lengths or styles
