Magic Chef Defrost Heater, Icing Kit, Fountain Heater

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.

The Radiant Heater is an OEM replacement part for Whirlpool refrigerators. It is the defrost heater that provides a gentle warmth to prevent freezing and freezing within selected drawers and compartments.  Radiant Glass (Quartz), Length (Approx) - 9-1/4, 500 watts

Causes of a faulty heater can include operational wear from prolonged power on cycles. Exposure to condensation or spills may also impact insulation over time.

Symptoms include:  

• Inadequate or ineffective temperature control in heater zones
• Short cycling or failure to maintain set temperatures  
• Loose connections or damage to heating coils

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

This refrigerator defrost heater and thermostat assembly restores proper automatic defrosting. The heater melts ice buildup on the evaporator, while the thermostat shuts off power at the right temperature to protect components and keep cooling consistent.

• Heats the evaporator during the defrost cycle to clear frost and ice
• Thermostat opens the circuit as the coil warms, preventing overheating
• Helps restore airflow across the coil and stable fridge/freezer temperatures
• Common symptoms: heavy frost behind the freezer panel, poor cooling or warm temps, fan noise from ice contact, unit not defrosting

• Disconnect power before servicing; remove freezer shelves/bins and the rear panel to access the evaporator
• Carefully defrost built-up ice; note original wire routing and clip locations
• Transfer any brackets/clips and mount the new assembly in the same positions
• Ensure connectors are fully seated and wires are clear of the fan and moving parts before restoring power

This evaporator defrost heater melts frost from the evaporator coil during the automatic defrost cycle to restore airflow and stable temperatures. Replacing a failed heater helps prevent ice buildup that restricts cooling and leads to warm spots. What it does:

• Heats the evaporator coil to clear frost/ice during defrost
• Helps maintain proper airflow between freezer and fresh food sections
• Typical symptoms: heavy frost on the back panel/evaporator, weak cooling or rising temperatures
• Also cause evaporator fan noise from ice contact and longer run times

• 1 evaporator defrost heater

• Disconnect power before servicing; allow any ice to thaw
• Access the heater behind the freezer's rear panel; avoid damaging fins or refrigerant lines
• Secure the heater and route wires exactly as original, keeping them clear of the fan and sharp edges
• Restore power and verify the defrost cycle per the service procedure

This radiant-style defrost heater melts frost from the evaporator during automatic defrost cycles. Replacing a failed heater restores airflow and helps maintain consistent temperatures while preventing ice buildup on the freezer back wall.

• Heats the evaporator coil to clear frost/ice during the defrost cycle
• Promotes proper airflow for stable cooling performance
• Common fix for heavy frost on the back freezer panel, warming in the fresh food section, or a noisy evaporator fan contacting ice
• If the element tests open (no continuity), the unit will not defrost

• Disconnect power before servicing; allow built-up ice to melt for safe access
• Access from the freezer by removing the rear panel; handle the glass-sheathed element carefully
• Note wire routing and transfer any reusable shields, clips, or insulation from the original part if present
• After replacement, verify the defrost thermostat/sensor and control initiate a defrost cycle

Radiant Glass (Quartz), Length (Approx) - 20-1/4, 450 watts

This 12-inch defrost heater melts frost and ice from the evaporator so your refrigerator can run efficiently and keep food at the proper temperature. It replaces a failed heater to restore normal automatic defrost cycles. What it does:

• Warms the evaporator coils during the defrost cycle to remove frost and ice buildup
• Helps prevent reduced cooling and frost accumulation on the evaporator
• Commonly used when the freezer/back wall has visible ice or when defrost cycles fail
• Works with the fridge's existing defrost control/timer and thermostat to clear ice safely

• One 12-inch defrost heater

• Disconnect power to the appliance before starting any repairs
• Access usually requires removal of the evaporator cover; handle the evaporator and wiring carefully
• Verify correct heater orientation and secure connections; do not force or kink the element

This radiant defrost heater melts ice build-up on the evaporator coil so your refrigerator can maintain proper airflow and cooling. It restores normal defrost operation and helps prevent excessive frost accumulation. What it does:

• Radiant heating element designed to melt frost and ice from the evaporator coil during the defrost cycle
• Restores airflow and consistent cooling when the evaporator has been restricted by ice
• Common symptom: visible frost or ice on evaporator or in freezer compartment
• Common symptom: poor or uneven cooling, longer run times, or a freezer that cycles abnormally

• One radiant defrost heater (single unit as shown)

• Disconnect power to the appliance before servicing to avoid shock risk
• Access typically requires removing the evaporator cover; handle evaporator fins and heater carefully
• Inspect defrost thermostat/thermistor and defrost control components while replacing the heater — replace only the failed components

This heater and thermostat assembly replaces the dryer's heating module to restore normal drying performance by regulating and producing heat. It's a direct-fit assembly designed to simplify replacement and reduce diagnosis time. What it does:

• Provides the dryer's primary heating element and temperature control components.
• Regulates operating temperature via built-in thermostats/thermal cutouts.
• Stops heating when a thermostat or thermal cutoff opens, which can cause no-heat or under-heating symptoms.
• Helps address common symptoms like no heat, long dry times, or intermittent heating when diagnosed to this assembly.

• Disconnect power to the appliance before starting service to avoid shock or injury.
• Carefully discharge any residual heat and avoid contact with sharp sheet metal and the heating element.
• Inspect and replace any blown thermal fuses or damaged wiring.
• Follow model-specific instructions and torque/electrical guidelines from the OEM during installation.

Radiant Glass (Quartz), Length (Approx) - 17-3/4, 400 watts

This defrost heater melts frost buildup on the evaporator so your freezer or refrigerator can cycle normally and maintain proper cooling. It's a direct-replacement style heater that restores the appliance's automatic defrost function. What it does:

• Heats the evaporator coil during the defrost cycle to remove ice buildup
• Helps prevent poor cooling, frozen food, and excessive frost accumulation
• Works with the appliance's defrost thermostat/timer or control board to run only during defrost cycles
• Restores normal airflow by keeping the evaporator fins clear of ice

• Disconnect power before servicing to avoid shock or injury
• Replace only with the exact, compatible heater
• Inspect defrost thermostat, timer, and wiring when replacing the heater—replace any damaged components
