242044113 Frigidaire Refrigerator Defrost Heater Assembly is āaā resistive heating element āassembly designed to melt accumulated frost on anā evaporator coil in frostāfree refrigerators and freezers. The assembly typically includes the heater āelement itself, āmounting hardware or clipsand aā¢ short wire harness or connector configured for Frigidaire appliance models using this part number. As a component, it is indeed a simple electric heater sized to provide controlled āheat āduring scheduled ā£defrost cycles and ā£is specified to fit particular evaporator geometries and electricalā¢ connectors used by the manufacturer.
Within the appliance, the defrost heater assembly is positioned adjacentā£ to the evaporator coil and isā¢ activated by the refrigerator’s defrost control (a timer or āelectronic controlā£ board) ā¤for short intervals to remove ice build-up. It interacts directly with the defrost termination thermostat ā¢or thermal fuse (which prevents overheating)and indirectly with the evaporator fan and compressor by restoring normalā airflow ā¢and heat ā¢transfer onceā frost is cleared. Proper operation of ā¢the heaterā is critical to maintain evaporator efficiency, prevent restricted airflow, avoid intermittent coolingā problemsand ensure condensate drains correctly to the drain pan ā£rather than causing leaks or icing in the cabinet.
This article will explain the heater assembly’s āfunction andā¢ typical electrical and mechanical characteristics, discuss compatibility considerations for replacement,ā£ identify common failure symptoms (such as persistent frost buildup, āreduced ā£coolingor water leaks during defrost)and āoutline diagnostic andā troubleshooting approaches useful to technicians and learnedā appliance owners.ā¢ It will also cover practical replacement considerations-correct part selection,connector and mounting checks,associated defrost component testing (termination thermostat/thermal fuse and control board),and safeā£ procedures for āisolating power and verifying accomplished operation after service.

Function ā¢and Role of the Defrost Heater Assembly in Refrigerator Thermal āManagement
The 242044113 Frigidaire Refrigerator Defrost Heater Assembly is aā low-voltage resistance heater āmountedā in ādirect contact with or adjacent to the evaporatorā¢ coil; its purpose is toā melt accumulated āfrost during āscheduled defrost cycles so heatā£ transfer through the coil is restored. The assembly is energizedā by the defrost control (mechanical timer āor electronic board) and normally works with a defrost thermostat or thermal ācutoff that terminates heating when theā£ coil reaches a safe temperature. In ānormal operation the heater produces uniform heat along the ācoil length toā¢ prevent localized ā¤ice buildup that would reduce ā¤evaporator efficiency andā cause ā£longer run times āfor the compressor.
- Common failure symptoms: persistentā iceā£ on the backā wall, reduced ā¤cooling capacity, longer compressor on-timesor water āpooling from failed drainage.
- Basic diagnostic checks:ā£ verify continuity across the heater element,ā£ inspect the defrost thermostat and thermal fuse for open circuitsand confirm the control is initiating defrost cycles.
- Replacement ā¢considerations: ensureā¤ the heater’sā mounting style, connector type,ā£ and electrical ratings āmatch the refrigerator model listed for part 242044113.
Compatibility of the 242044113ā¢ assembly dependsā on ā£physical fit and electrical characteristics; technicians should confirm ā¤mounting bracket location andā connector pinout āagainst the serviceā manual before installation. For practical troubleshooting, measuring the element’s resistance and checking for an intact thermal cutoff is faster than intermittent run-timeā observations – a failed element shows open circuit, while a shorted thermal fuse can show continuity on the fuse but no heating during a control-initiated defrost.ā¢ When replacing the assembly, follow electrical safety practices and verify the defrost control initiates and terminates the cycle so the new heater is not leftā energized continuously.

How the 242044113 Frigidaire Refrigerator āDefrost Heater Assembly Integrates ā¢with the Evaporator, Timer, āand Defrost Thermostat
The 242044113 Frigidaire Refrigerator Defrost Heater Assembly is a resistive heating element mounted along the evaporator coil that melts frost during ā£the service defrost period. āwhen ā¢the ā¤defrost timer orā electronic control closes ā£theā¤ defrost circuit, line voltage is ā¤applied to the heater and āthe evaporator temperature begins to rise; ā£the defrost thermostat monitors āthat rise and interrupts power once āthe coil reaches itsā¤ termination ātemperature. In practice this means the heater, the evaporator, the defrost control (mechanical ātimer or electronic control board)and ā£the defrost thermostat operate as a coordinatedā subsystem: the control āsupplies power only during the scheduled defrost āinterval, the heater provides the thermal energy to remove iceand ā¢the thermostatā¤ prevents overheating and ends the cycle when the coil is sufficiently warm.
- Typical diagnostic checks: force a defrost cycle from āthe control and measure voltage at the heater terminals;ā¤ check heater element continuity for an openā£ circuit; verify ā£the thermostat has continuity when cold and opens as theā coil warms.
- Failure behaviors: an open heater element yields progressive frost build-up and reduced cooling; āa thermostat stuck open prevents defrosting, while a thermostat stuck closed or a control that fails to time out can cause excessive melt and water leakage.
- Compatibility considerations: replacement must match mounting style,connector ātype,and āthermal cutoff behavior for the specificā Frigidaireā model to ensure proper ā¤alignment with the evaporator and correctā termination of the defrostā cycle.

| 242044113 Frigidaire Refrigerator Defrost Heater assembly | Resistive element that transfers heatā to evaporator fins to remove ice during ā¢defrost. |
| Evaporator | Cold coil where frost accumulates and which must be heated uniformly to ārestore airflow and heat exchange. |
| Defrost Timerā¢ / Electronicā Control | Schedulesā¢ or commands the defrostā£ interval and switches power between cooling and defrost functions. |
| Defrost Thermostat | Temperature-sensitive switch that āopens to terminate the defrost cycle once the evaporator reaches the set temperature. |
For technicians and informed owners, practical replacement āor troubleshooting focuses on verifying the sequence: initiate defrost fromā the control, confirm line voltage present ā¢at āthe 242044113 heater during the defrost interval, confirm element continuity and inspect the thermostat for open/closed behavior as temperature āchanges. Physically, the heater must make consistent contact or be correctly routed along the evaporator for uniform melting; mismatched assemblies can leave cold spots and residualā¢ ice. Always remove power ā¤before probing circuits; when diagnosing persistent frost orā water leaks, examine all four ā¤elements of the subsystem ā(heater, evaporator, control,ā thermostat) rather than replacing the heater alone without confirming control and sensor operation.
Common Failure Symptoms and Diagnostic Indicators of Defrost Heater Assembly Malfunction
The 242044113 Frigidaire Refrigerator Defrostā¢ Heater Assembly is a tubular heatingā¢ element mounted ā¤along the evaporator coilā¢ that meltsā accumulated frost ā¤during the ā£defrost cycle so theā evaporator can transfer heat efficiently. It operatesā under ācontrol of the refrigerator’s defrost control (timerā¢ or electronic control board) andā aā temperature-sensitive ādefrost thermostat; the heater should ā¤present a measurable resistance and ā£draw current only during ā¢the ā¤commanded defrost āinterval. Physically, this assembly must matchā¢ the evaporator geometry and mounting points ofā the specific Frigidaire ā£model it serves,ā so mechanical fitā£ andā terminal type āare practical compatibility checks before replacement.
failures of the defrost heater typically produce predictable refrigeration āsymptoms and clear diagnostic traces. Common observable indicators include persistent ice build-up on āthe evaporator, ā¢reduced cold-air circulation into compartmentsand intermittent compressor āoperation as the system struggles to reach set temperatures.ā¤ Technically confirm failure by āchecking āfor continuity across the ā¢heater element ā¤with aā¤ multimeter ā(open circuit indicates aā broken element), ā¢measuring expected ā¢resistance range for the model,ā and verifying āthat the defrost thermostat and control signal are present during a forced defrost. For example, a technician can initiate a āmanual defrost cycle, verify lineā¤ voltage at the ā¤heater terminalsā¢ during that cycleand compare measured current and resistance against āthe ā¤manufacturer’s reference values to isolate whether the heater, thermostator control module is at āfault.
- Ice accumulation on āthe evaporator orā£ walls despite normal compressor operation.
- no continuity or abnormally high resistance measured across the heater āterminals.
- Heater terminals remain unenergized āduring a forced/observed defrost cycle (control or wiring issue).
- Visibleā breaks, corrosionor burn marks āon the heater tubing or lead āconnections.

Compatibility, Replacement Considerations, Installation Steps, āand Troubleshooting Procedures for the Defrost Heater assembly
The 242044113 Frigidaire Refrigerator Defrost Heater Assembly is the resistive element āinstalled along the evaporator coil that melts frost accumulation during āscheduled defrost ā¤cycles. It is indeed energized by theā appliance ādefrost control or timer and monitored by a defrost thermostat; the heater itself presentsā¢ a low-ohm resistive pathā¢ designed for mains voltage operationā£ (commonly 120 ā¢VAC inā£ North America). Typical failure modes are open circuit,a short to chassisā ground,or ā¢localizedā burnout that reduces heating output-each of which produces excessiveā¢ frost on theā¢ evaporator,reduced airflow,and long run-times for theā compressor. Confirm fitment against the OEM part number and inspect mounting clips and the connector styleā¤ before replacement ā¢because physical routing and clip positions must match ā¤to avoid contactā¤ with the evaporatorā¤ fan or adjacent wiring harnesses.
When ā¤replacing or troubleshooting the assembly take ā£a ā¤methodical approach: disconnect āpower, ā£removeā¢ the evaporator cover, visually āinspect the heater for breaks orā burn āmarksand verify continuity with āa multimeter. If the heater is open, also test the defrost thermostatā and the control board or timer output before replacingā¢ the heater; ā¤a good heater that receivesā¤ no voltage indicates a control or thermostat fault.Installationā steps typically include removing ā¢the evaporator cover, releasing āthe mounting clips, ā¢transferring the heater to theā¤ same routing andā clip āpositions, reconnecting the connector, ā£and āperformingā a forced defrost or control-board diagnostic to confirm heating and proper ādrain of meltwater. Common troubleshooting ā¢checks are continuity of the āheater, continuity/operation āof the defrost ā¤thermostat at itsā rated temperature, ā£and verifying the defrost control supplies voltage to the heater ā¤during a forced cycle.
- Symptoms: heavy ā¢frost/ice on evaporator, warm freezer, compressor running continuously.
- Pre-replacement checks:ā¤ multimeter continuity across the heater, continuity of defrost thermostat, verify control outputs during a forced cycle.
- Basic āinstallation checklist: remove power, note routing and clips, disconnect connector, āinstall newā£ heater in same orientation,ā¢ secure clips, reassemble and forceā defrost to verify.
- Post-install verification: confirm heater draws current during defrost, observeā¢ ice melting and drain flow,ā¢ check for no contact with fan or wiring.

Q&A
What is the 242044113ā Frigidaireā£ defrost heater assemblyā£ and what dose it do?
The 242044113 is an OEM defrost heaterā¢ assembly for many Frigidaire refrigerators. Its job is to melt frost and ice that accumulates on the ā¢evaporator coil during normal operation. The refrigerator runsā periodic defrost cycles;ā when the heater is powered it warms the evaporator enough to melt accumulatedā ice so the unit canā£ maintain proper ā¢airflowā and cooling.
How doā¢ I know if the defrost heater assembly is failing?
Common symptoms include excessive frost orā¤ a thick iceā¢ build-up ā£on the evaporator, poor cooling in the freezer or refrigerator compartments, ā£long orā continuous compressor run timesand waterā pooling under the freezer after a defrost cycle. Ifā the heater is open (no continuity) or not receiving power duringā¢ a defrostā¤ cycle, it will notā¢ melt the ice.
Can I test the defrost heater myselfand if so how?
You can perform a basic ācontinuity test with the refrigerator unplugged. Remove the interior back panel to access theā evaporator and heater, disconnect the heater wiring harnessandā¢ use a multimeter setā¢ to the ohms/continuity function. A working ā£heater will show low resistance (typically a few ohms to a ā£fewā dozen ohms depending āon model). Anā open circuit ā£(infinite resistance) indicates āa failed heater. Do not attempt live-voltage tests unless you are ātrained and take proper safety precautions.
What voltage does the defrost heater useand can I safely jump it ātoā¤ test?
Inā North america most refrigerator defrost heaters operate on the appliance’s āmains voltage (about 120 VAC). You should not apply mainsā power directly to a heater as a diagnostic unless you are qualified. Incorrect testing or bypassing safety components can cause ā¢shock, fireor furtherā¤ damage. For safe diagnostics, use a multimeter to check for voltage presence during a defrost cycle or āhaveā¢ a qualified technicianā perform ā¤live tests.
How do Iā replace theā¤ 242044113 defrost ā¢heater āassembly?
Basic replacementā¤ steps (overview): unplug the refrigerator, remove the freezer interior panel to expose the evaporator, disconnect the āheater wiring and any mounting clips or brackets, remove the oldā£ heater and install the new assembly, reconnect wiring, reassemble panelsand restore power. as the evaporator and heaterā¤ areā insideā¢ a sealed ā£compartment, follow the ā¢refrigerator’s serviceā manual and safety procedures. If you’re not pleasant with disassembly or electrical components, hire a qualified appliance technician.
What other components should I check if the heater isā fine but ā¢defrost ā¤still fails?
Check the defrost thermostat/thermistor and the defrostā£ control (timer or main control board). The thermostat (or bi-metal thermostat)ā must close at low temperature to allow ā¤the heaterā to receive powerand the control initiates defrost cycles.Aā¤ failed thermostat, blown thermal fuseor bad control board can āprevent theā heater fromā receiving power even if ātheā heater itself is good.
Is it acceptable toā run the refrigerator with ā¢the defrost heater āremoved or bypassed?
No. Running theā refrigerator long-term without a ā¤functioning defrost system will lead to heavyā£ frost on the evaporator, reduced air flow, poor cooling, higher energy useand possible compressor damage. Temporary manual defrosting is possible for short periods, but you āshould repair ā¢orā£ replace theā heater and any faulty controls promptly.
Where can I buy the 242044113 and how do I confirm fitment for my model?
The 242044113 can be purchased from Frigidaire parts distributors, authorized dealersand reputable online ā£appliance parts retailers.ā¤ To confirm fitment, ā£use your refrigerator’s exact āmodel number (usually found onā¢ a tag inside the fridge), search OEM parts lists or the seller’s compatibility toolor consult your appliance’s service manual.Buying OEM āor OEM-equivalentā parts and verifying compatibility āreduces risk ofā£ incorrect fit or performance issues.
