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

This defrost heater and thermostat assembly melts frost from the evaporator and shuts off at the proper temperature during the defrost cycle, restoring airflow and helping the refrigerator maintain steady, reliable cooling performance.

• Heats the evaporator to clear frost/ice during the automatic defrost cycle
• Thermostat opens to terminate heat once a safe temperature is reached
• Helps restore air circulation to the fresh food section
• Common failure signs: heavy frost on the freezer back wall/evaporator, poor cooling or warm fridge, fan noise from ice contact, little or no water in the drain pan after "defrosts"

• Disconnect power before service; work on a fully de-energized appliance
• Access is typically behind the freezer's rear panel; remove shelves/ice components as needed
• Fully defrost before installing the new assembly to prevent damage and ensure proper fit
• Reinstall in the original locations; clamp the thermostat to the evaporator tubing and route wiring exactly as factory, away from sharp edges and moving parts

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 dishwasher heater mounts at the bottom of the tub to raise wash-water temperature and boost the heated dry cycle. Replacing a failed element restores proper heating, helping cycles finish on time and improving drying performance.

• Heats wash water to the correct temperature for effective cleaning
• Aids the dry cycle by evaporating moisture from dishes
• Common symptoms of failure: dishes not drying, water staying cool, longer-than-normal cycles, sanitize option not reaching target temperature
• May show visible damage or test open for continuity

• Disconnect power and shut off water supply before servicing
• Pull the dishwasher forward for access to the underside
• Remove wires and retaining nuts from the old element; lift it out through the tub openings
• Seat the new element evenly, tighten hardware securely without overtightening, reconnect wires, then run a short cycle and check for leaks at the ports

Includes heater and instructions. Please note: This heater kit will NOT work on Frigidaire refrigerators manufactured prior to 2001, on side-by-side or counter-depth models, or on models with electronic controls.

This evaporator defrost heater melts frost from the freezer's evaporator coil during the automatic defrost cycle, restoring proper airflow and cooling. Replacing a failed heater helps prevent recurring ice buildup and temperature swings.

• Heats the evaporator coil at set intervals to clear ice
• Maintains airflow so the fresh food section and freezer cool consistently
• Common signs of failure: heavy frost on the back freezer panel or evaporator
• Other symptoms may include warm refrigerator temperatures, reduced airflow, or fan noise from ice contact

• Disconnect power before servicing; wear appropriate PPE
• Access the heater behind the freezer's rear panel; defrost ice with warm air/steam—avoid sharp tools
• Reinstall in the original position; keep wiring clear of the fan and moving/hot parts; ensure secure harness connections
• After reassembly, verify the defrost cycle per service instructions; if frost returns, also check the defrost thermostat/bi-metal and control

This defrost heater mounts at the evaporator and melts frost during the automatic defrost cycle. Replacing a failed heater restores airflow, helps prevent ice buildup, and brings cooling performance and temperature stability back to your refrigerator. What it does:

• Heats the evaporator coil during defrost to clear frost and ice
• Keeps air passages open to maintain even cooling between compartments
• Common failure signs: thick frost on the rear freezer panel or iced-over evaporator
• Resulting symptoms may include poor cooling, a warm fresh food section, or fan noise from ice contact

• 1 defrost heater

• Disconnect power before servicing; let heavy ice thaw and never use sharp tools on coils or liners
• Remove the freezer's rear panel to access the heater; note wire routing and clip positions
• Transfer any existing brackets/clips and secure the heater in the original location, clear of plastic parts and the drain trough
• Check heater and defrost thermostat continuity before reassembly; ensure all connectors are fully seated

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

This defrost heater kit warms the evaporator during the automatic defrost cycle to melt frost and keep air moving. Replace it when ice builds up on the freezer coils and temperatures rise or airflow is restricted.

• Heats the evaporator coil during defrost to clear accumulated frost/ice
• Helps maintain proper airflow and stable temperatures in both compartments
• Symptoms can include heavy frost on the back wall/evaporator cover, reduced cooling, or fan noise from ice contact
• A failed heater can leave the defrost system unable to clear ice, restricting airflow

• Disconnect power to the refrigerator before servicing
• Access the heater behind the freezer's rear panel; safely remove heavy ice before replacement
• Move wires and clips one at a time, routing exactly like the original to avoid pinched or exposed conductors
• After replacement, monitor defrost operation; icing persists, also check the defrost thermostat and control
