Parts for Frigidaire MFU14F3GW4: 04 - System Parts

This aluminum strap secures the defrost heater firmly against the evaporator coil to maintain proper contact during defrost. Correct contact improves heat transfer so frost melts evenly and helps prevent recurring ice buildup on the evaporator.

• Secures the defrost heater to the evaporator for proper contact and heat transfer
• Promotes complete, even defrosting across the evaporator coil
• Helps reduce repeat frost/ice accumulation caused by a shifted or loose heater
• Typical clues include a loose heater, uneven frost pattern, or rattling near the evaporator

• Disconnect power and allow ice to melt before accessing the evaporator
• Use care around sharp fins and fragile refrigerant tubing; do not puncture or deform the coil
• Position the heater per your model's parts diagram and tighten the strap for firm, even contact
• Verify wiring is routed clear of the fan and moving parts before reassembly

Includes service line.

The Defrost Thermostat is an OEM part for Frigidaire refrigerators. It monitors the temperature of the evaporator coils and activates the defrost heater when necessary. This process prevents frost buildup on the coils, ensuring the refrigerator maintains optimal cooling efficiency.

You should replace the defrost thermostat if it becomes faulty or damaged. Common causes of a bad defrost thermostat include electrical failures, regular wear and tear, or temperature fluctuations that can degrade the component over time.

Symptoms of a bad defrost thermostat include:

• Excessive frost buildup on the evaporator coils
• Refrigerator not cooling properly
• The defrost cycle not activating
• Increased energy consumption

This OEM replacement is also compatible with Electrolux, Gibson, Kelvinator, and Kenmore models.

The Defrost Timer is an OEM replacement part for Frigidaire upright freezers. It serves as a crucial component responsible for regulating automatic defrost cycles.

Causes of a faulty defrost timer relate to 20,000+ hours of constant exposure to freezer temperatures as low as -10 degrees Fahrenheit. Such extremes can compromise electrical switching mechanisms over prolonged usage periods.

Symptoms of a failed defrost timer include:

• Inability to initiate automatic defrost modes  
• Excessive ice and frost accumulation inside cabinet
• Warm areas detected due to impaired fan circulation
• Diagnostic codes indicating defrosting problems

This genuine Frigidaire replacement part is compatible with Kelvinator and some Kenmore units as well.

This compressor grommet is a rubber mounting isolator that cushions and secures the compressor to the appliance chassis, helping reduce vibration and noise while preventing metal-to-metal contact and premature wear. What it does:

• Cushions compressor movement to reduce vibration transmitted to the cabinet
• Dampens noise and rattling caused by compressor operation
• Prevents direct metal-to-metal contact that can wear mounting points
• Helps keep the compressor positioned and secured under load

• Disconnect power to the appliance before accessing the compressor or base pan
• Replace grommets while supporting the compressor to avoid strain on lines and connections
• Inspect remaining mounting grommets; replace all worn isolators for best performance

The product featured is a Frigidaire refrigerator compressor. The compressor is a vital component for the cooling and freezing process of a refrigerator. A compressor works together with the evaporator in providing the cold air needed to keep everything at the desired temperature. When a compressor fails, this could have an effect that calls for an emergency repair. Losing the compressor function means the refrigerator stops getting cold in both compartments. Prolonging the repair could mean the loss of all the food items stored inside. A faulty compressor may become very loud when it operates. Users may hear a slight clicking sound on a compressor that's entirely out of commission. This is the relay clicking in an attempt to power the compressor. If a compressor does go out, keep the doors of the freezer and refrigerator shut. There's a chance the food can be salvaged if repairs take place fast enough. This compressor is a genuine OEM product and is sourced directly from the manufacturer and is only available as an individual component. Frigidaire, Kenmore, and Maytag refrigerators can be repaired with this component.

This electrical relay assembly controls power to a major appliance circuit, restoring reliable switching and helping appliances start and run properly. Replace a failed relay to stop intermittent starts, no-start conditions, or unreliable operation. What it does

• Switches electrical power to motors or heating circuits when the appliance control signals for operation
• Commonly fails after arcing or overheating, causing intermittent or no-start symptoms
• May cause a unit to click repeatedly, run intermittently, or fail to power specific functions
• Restores correct electrical switching when installed in place of a damaged relay

• Disconnect power before accessing control panels or wiring to avoid shock
• Access and removal typically require removing the control panel or top panel; keep track of screws and wire locations
• Replace with the exact part number and reconnect all terminals securely; do not bend or damage connector pins

This retainer lead wire secures appliance wiring to keep harnesses organized and away from heat or moving parts, reducing wear and accidental disconnection. It's a simple replacement to restore proper wire routing and protection. What it does:

• Clips or holds the wiring harness in place to prevent chafing and strain
• Helps keep wires away from hot surfaces, vents, or moving components
• Reduces risk of intermittent electrical connections caused by loose wiring
• Restores factory routing after service or component replacement

• Disconnect power to the appliance before installing to avoid shock or injury
• Remove any panels necessary to access the original retainer and wiring route
• Replace like-for-like, seating the retainer securely so the harness cannot shift
• If wires show damage or insulation wear, inspect further and replace damaged wiring before reassembly
