Estate Defrost Heater, Icing Kit, Fountain Heater

The Heater is an OEM part for Whirlpool refrigerators. This part prevents frost buildup by heating the evaporator coils during the defrost cycle. This part ensures that air flows freely over the coils, improving the efficiency of the cooling system and maintaining the refrigerator at the optimal temperature. 

Causes of a bad heater can include electrical failures, such as a blown fuse or a faulty wiring connection, or physical damage to the heater element itself.  

Symptoms of a bad Heater include:

• Frost buildup on the evaporator coils
• The refrigerator and freezer not maintaining the desired temperatures
• Increased energy consumption as the refrigerator works harder to cool
• Unusual noises from the refrigerator as the fan hits frost buildup

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

The Defrost Heater is an OEM part for Whirlpool refrigerators. It is responsible for melting frost and ice that can accumulate on the evaporator coils, ensuring the refrigerator operates efficiently.

Causes of a bad defrost heater can include electrical issues such as short circuits or open circuits, physical damage to the heater element, or wear and tear from repeated heating cycles over time.

Symptoms of a bad defrost heater include:

• Frost buildup on the evaporator coils
• The refrigerator not cooling properly
• Frequent or continuous running of the compressor
• Water leakage inside the refrigerator due to melting ice

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

The Defrost Heater is an OEM replacement part for Whirlpool French door refrigerators. It is an electric heating element strategically placed within the refrigerator compartment and freezer liners. This component aids in preventing excessive moisture buildup from condensation formed during normal operation. 

Causes for heater failure include standard component degradation from prolonged use. Exposure to moisture accumulating over time can damage wiring insulation or short-circuit coil filaments as well.

Symptoms of an inadequate defrost heater involve:

• Frost buildup interfering with door seals and interior shelving
• Promotion of mold/mildew growth from sustained dampness
• Food spoilage risks due to the inability to regulate proper humidity 

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

The Defrost Heater is an OEM part for Whirlpool refrigerators. This heater turns on during the defrost cycle to melt the frost on the evaporator coils. If you need the defrost thermostat order WP4387490

Causes may include cracked heater elements reducing heat output or open circuit damage limiting functionality over time. 

Symptoms of a faulty heater involve:

• Periodic refrigerator odors
• Prolonged defrost cycles or remaining ice
• Frost and ice buildup beyond normal amounts

This is a genuine Whirlpool OEM replacement this part is also compatible with Maytag, Jenn-Air and some Kenmore models.

This defrost heater melts frost from the evaporator during the automatic defrost cycle to keep air moving and temperatures stable. Replacing a failed heater restores normal cooling and helps prevent frost from building up on the freezer wall and coil.

• Heats the evaporator coil during defrost to clear accumulated frost and ice
• Helps maintain proper airflow and consistent refrigerator/freezer temperatures
• Common symptoms: heavy frost on the evaporator cover, refrigerator section warming, weak airflow, or fan noise from ice contact
• A failed heater often tests open (no continuity) with a multimeter

• Unplug the refrigerator before servicing; work with dry hands and tools
• Access the heater behind the freezer's rear panel; avoid damaging evaporator fins/tubing
• Note wire/connector positions and transfer any clips or shields from the old part if applicable
• After installation, reassemble panels securely and verify normal operation

This defrost heater warms the evaporator during automatic defrost to melt built-up frost so air can move freely and temperatures stay consistent. Replace a failed heater to restore normal cooling and end recurring frost on the freezer panel.

• Melts ice from the evaporator coil during the defrost cycle
• Prevents frost buildup that restricts airflow and causes warm spots
• Helps maintain stable refrigerator and freezer temperatures
• Typical failure signs: heavy frost on the back wall, reduced cooling, fan noise from ice contact, frequent manual defrosting

• Disconnect power before servicing; wear cut-resistant gloves
• Access through the freezer compartment; remove shelves/ice bin and rear panel to reach the evaporator
• Match wire connections and route leads exactly as original; keep wiring clear of the fan and sharp edges
• After reassembly, restore power and monitor a defrost cycle; if frost quickly returns, also evaluate the defrost thermostat and control
