Gibson Refrigerator Defrost Heater, Icing Kit, Fountain Heater

The Defrost Heater is an OEM part for Frigidaire refrigerators, playing a critical role in the appliance's defrost system. This component is designed to melt away frost and ice that accumulate on the evaporator coils, ensuring that air can flow freely and the appliance maintains optimal cooling efficiency.

Causes of failure might include a burnt-out heating element, damage to the heater's electrical connections, or a malfunction in the control system that fails to activate the heater during the defrost cycle. 

Symptoms of a bad Defrost Heater include:

• Frost build-up on the evaporator coils, leading to reduced cooling efficiency.
• The freezer or refrigerator compartment is too warm.
• The appliance is constantly running in an attempt to maintain the set temperature.
• Pools of water or ice on the floor of the freezer compartment due to incomplete defrosting.

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

The Defrost Heater Kit is an OEM part for Frigidaire refrigerators. This part is responsible for melting frost and ice buildup on the evaporator coils during the defrost cycle.  

Causes of a bad defrost heater can include regular wear and tear, electrical issues, or physical damage.  

Symptoms of a bad defrost heater include:

• Excessive frost or ice buildup in the freezer
• The refrigerator or freezer not cooling properly
• The defrost cycle not initiating
• Water leaking inside the refrigerator due to melting ice

This OEM Frigidaire part is also compatible with Electrolux, Gibson, Kelvinator and some Kenmore models.

This defrost heater kit restores the automatic defrost cycle by melting frost from the freezer's evaporator coils. Replacing a failed heater helps clear ice buildup, restore airflow, and stabilize temperatures for reliable cooling performance.

• Heats the evaporator during defrost to remove frost and ice
• Helps maintain proper airflow through the coils for consistent cooling
• Common symptoms of a failed heater: heavy frost on the back freezer wall, weak airflow, warming temps, or cooling that improves after a manual defrost
• Supports efficient operation by preventing ice from re-forming on the evaporator

• Unplug the refrigerator before servicing; let any sharp parts or coils warm up to avoid damage
• Access the heater behind the freezer's rear panel; handle the element carefully to avoid damage
• Note wire routing and mounting before removal to match the original configuration
• Check the defrost thermostat and defrost control/timer for proper operation

This defrost heater warms the evaporator coil during the automatic defrost cycle to melt frost and ice, restoring airflow and consistent temperatures. Replace a failed heater to stop recurring frost buildup and uneven cooling. What it does:

• Heats the evaporator to clear frost/ice so air can circulate
• Helps maintain stable refrigerator and freezer temperatures
• Symptoms include heavy frost on the back freezer panel or coils, poor cooling, evaporator fan noise from ice contact, or frost returning soon after a manual defrost

• 1 defrost heater

• Disconnect power before servicing
• Remove freezer shelves and the rear interior panel to access the evaporator area
• Transfer the heater into the original clips/brackets and route wiring exactly as original, away from sharp edges and the fan
• If frost returns after replacement, also test the defrost thermostat and the defrost control

• With power disconnected, the heater should show continuity on an ohmmeter; an open circuit indicates a failed element

The defrost heater mounts at the evaporator to melt accumulated frost during the automatic defrost cycle. Replacing a failed heater restores airflow and temperature stability, preventing ice buildup that blocks vents and reduces cooling performance. What it does:

• Heats the evaporator coil to clear frost during the defrost cycle
• Maintains airflow across the coil for consistent cooling
• Common symptoms: heavy frost on the back wall or coils
• Weak/no airflow or fan hitting ice; warmer temperatures; long run times

• One defrost heater

• Disconnect power before servicing
• Access the evaporator and allow heavy ice to thaw—do not force ice off the fins
• Transfer any mounting clips and route wires like the original, away from sharp edges
• Handle the element carefully; reinstall the evaporator cover before restoring power

The defrost heater warms the evaporator during automatic defrost to melt frost so air can circulate freely. Replacing a failed heater helps stop heavy ice buildup, restore cooling performance, and prevent fan noise from ice contact.

• Clears frost from the evaporator so cold air can move between compartments
• Helps maintain stable temperatures and efficient cooling
• Common symptoms of a failed heater: thick frost on the back freezer panel, poor cooling, or fan scraping ice
• Electric resistance element that often tests open (no continuity) when failed

• Disconnect power before servicing; do not work on a live appliance
• Remove freezer shelves/drawers and the rear panel to access the evaporator and heater
• Allow ice to thaw; handle fins and tubing carefully to avoid damage
• Route wiring and clips as originally installed and ensure tight electrical connections before reassembly

This defrost heater kit heats the evaporator to melt frost and ice buildup so the refrigerator can cycle normally and maintain proper cooling. It's a direct-replacement kit for units that use a heater-style defrost assembly. What it does:

• Warms the evaporator coil during the defrost cycle to remove frost and ice
• Helps restore normal airflow and cooling when frost buildup blocks the evaporator
• Commonly used when a refrigerator has excessive frost, poor cooling, or no active defrost
• Works with the existing defrost control and thermostat to allow automatic defrost cycles

• Disconnect power to the appliance before starting any service
• Handle evaporator fins and sharp sheet metal with care; wear gloves and eye protection
• Reassemble panels and restore power; check for proper defrost operation after installation
