WR49X10173 GE Refrigerator Dispenser Water TUBE Heater Kit is a heater assembly intended for use on the water supply tube inside a refrigerator door or cabinet. It is a low-profile resistive heating component sold as a service kit to prevent freezing of the dispenser water line; the kit generally provides the heater element and the necessary mounting hardware to secure it along the tube. This component is a field-replaceable part used in models with through-the-door water dispensers where the exposed water line runs through colder ambient spaces in the cabinet or door cavity.
Inside the appliance, the heater kit’s role is to keep the water tube above freezing temperature so that the dispenser valve, water line and any downstream components remain operable. It interacts directly with the water line and indirectly with the dispenser actuator/valve assembly, the door harness and the refrigerator’s electrical control system when powered. Proper installation requires routing and securing the heater along the length of the tube,maintaining electrical connections through the door harness or terminal block,and ensuring any temperature-sensing or protective devices associated with the heater are correctly integrated with the appliance controls.
In this article readers will find a technical overview of the heater kit’s function, guidance on model compatibility and installation locations, common failure symptoms to watch for (such as, frozen dispenser lines, intermittent flow or evidence of heater open circuits), practical troubleshooting steps such as continuity and resistance checks and voltage verificationand replacement considerations including safe isolation of power and water, recommended mounting practices and verification after installation.

Function and Role of the Refrigerator Dispenser Water Tube Heater in Preventing line Freezing and Maintaining Water Flow
The WR49X10173 GE Refrigerator Dispenser Water TUBE Heater Kit is a low‑power resistive heating element intended to keep the dispenser water tube warm enough to prevent ice formation inside the door or dispenser cavity. By coupling thermally to the tubing that carries water from the reservoir or valve to the dispenser, the heater maintains conductive heat transfer along the tube wall so water can flow freely at low ambient or internal cabinet temperatures. In GE in‑door dispenser designs the kit is installed along the section of tube that is most exposed to cold air; compatibility varies by model, so technicians should confirm fit and wiring against the refrigerator’s service manual before installation.
In practice the heater minimizes the formation of ice plugs that cause reduced flow, sputtering or complete blockage of the dispenser. Failure modes include open heater element, broken wiring or poor thermal contact to the tube; diagnostics commonly include a visual inspection for frost patterns, continuity check of the heater elementand verification of proper connector voltage per the wiring diagram. Replacing the kit is a targeted repair when persistent freezing occurs despite correct valve operation and proper door sealsand correct routing and secure attachment of the heater to the tubing are essential for effective thermal transfer and long‑term reliability.
- Common symptoms addressed: reduced or intermittent flow, sputtering, visible frost on tubing or inside door cavity.
- Key features: low‑power resistive element, direct attachment to water tube, requires correct wiring/connector compatibility.
- Typical checks for technicians: continuity test, connector and harness inspection, verify tube routing and thermal contact.

How the WR49X10173 GE Refrigerator Dispenser Water TUBE Heater Kit Operates Within the Appliance’s Plumbing and Electrical subsystems
WR49X10173 GE Refrigerator Dispenser Water TUBE Heater Kit is a localized resistive heating assembly designed to prevent the small-diameter dispenser water tube from freezing where it passes through cold compartments or the door. The heater wraps around or mounts adjacent to the plastic tubing and delivers low-wattage heat under thermostatic or electronic control so that water remains above freezing without significantly warming the supply. In models that route the feed line through the freezer or across the door edge, the kit maintains flow continuity during extended idle periods and cold ambient conditions; in some configurations the element contains its own temperature limiter, while in others the refrigerator’s control board switches the heater on as needed.
The heater integrates with both plumbing and electrical subsystems: mechanically it clamps to the line or secures with clips to provide conductive heat transfer to the tube wall; electrically it ties into the refrigerator’s wiring harness on a circuit shared with other low-wattage heaters or is routed to a dedicated connector. Compatibility depends on model-specific harness connectors, mounting pointsand tube diameter, so matching the part number and verifying connector style is necessary before replacement. Typical service tasks include verifying continuity of the heater element, checking for the correct switching voltage at the connector when the unit requests heatand replacing the kit if the element is open or the thermostat fails; technicians should isolate power and drain water before accessing the liner or door cavity.
- Common symptoms and quick checks: no water flow or reduced flow with audible ice formation - check for visible ice in the dispenser path, measure element continuity with a multimeterand verify presence of switching voltage at the connector during cold cycles.
- Installation/compatibility tip: confirm harness connector and mounting clip positions against the refrigerator model’s parts diagram before ordering the kit.

Diagnostic Indicators and Common Failure Symptoms of the Dispenser Water Tube Heater Assembly
WR49X10173 GE Refrigerator Dispenser Water TUBE heater Kit is a low‑wattage resistive heater assembly that attaches to the dispenser water tube to prevent freeze‑ups and condensation that block water flow. The assembly is intended to work with the refrigerator’s existing harness and control signals, energizing intermittently under low ambient or control‑board conditions that threaten ice formation. Functionally it dose not alter valve timing or pump operation; rather it maintains the tube temperature above the point where ice forms, preserving consistent flow and preventing the common symptom of an intermittently clogged dispenser line in cold environments or near freezer partitions.
Technicians can identify a failing tube heater by a combination of flow behavior and measurable electrical faults.Typical diagnostic steps include visually inspecting the tube and connector for frost or corrosion, verifying continuity across the heater elementand confirming the control board applies power when the heater is expected to run. Practical examples: if dispensing stops after long idle periods in a cold room and flow resumes after manual thawing, the heater is a likely culprit; if continuity is open at the element, replacement is indicated. Distinguish heater failures from filter, valveor pump faults by using continuity and voltage checks along with observed symptoms.
- Reduced or no water flow after periods of inactivity or in cold ambient conditions
- intermittent flow that clears temporarily after manual thawing
- Frost or ice accumulation on or adjacent to the water tube
- Open circuit or no continuity across the heater element
- Corroded, discolored, or damaged harness/connector at the heater

Compatibility with GE Refrigerator Models, Replacement Considerations, Step‑by‑Step Installation and Troubleshooting Diagnostics
WR49X10173 GE Refrigerator Dispenser Water TUBE Heater Kit is a low‑wattage heater assembly intended to prevent the dispenser water line routed through a refrigerator door from freezing or forming partial ice blockages. Technically, the kit provides localized heat to the plastic water tube and is fitted where the tube traverses the door-to-body interface; correct fitment requires matching the harness connector, mounting bracketsand tube length to the refrigerator’s door architecture. Compatibility is limited to GE models that use an in‑door water routing and a removable heater assembly-verify the refrigerator model number against OEM parts lists or service manuals before ordering, as mismatched connectors or bracket geometry will prevent proper installation and can cause leaks or loss of electrical continuity.
Installation and troubleshooting follow standard appliance electrical and fluid isolation practices: remove power, remove the interior door panel to expose the tube, inspect and replace the heater assemblyand verify electrical continuity and mechanical mounting before restoring service. Diagnostics focus on two measurable conditions: electrical continuity of the heater element (an open circuit indicates a failed heater) and presence of supply voltage at the connector when the system is expected to energize; common operational symptoms include partial or complete loss of dispensed water flow, intermittent freezing inside the door, or cold spots along the tube. For a practical workflow, technicians should trace the harness for corrosion, confirm secure tube clamps to prevent flex‑induced fatigue, and test the assembled system with water flow checks after installation.
- Verify model compatibility and harness type before purchase.
- Power off and remove door panel to access the water tube and heater assembly.
- Measure heater continuity with an ohmmeter; infinite resistance = replace.
- After replacement, confirm connector voltage and perform a water‑flow test to ensure the tube remains ice‑free under normal conditions.

Q&A
What is the purpose of the WR49X10173 dispenser water tube heater kit?
The WR49X10173 is an OEM heater assembly intended to prevent the refrigerator door water/dispenser tube from freezing. It wraps around or runs alongside the water line and provides heat when required so water can flow to the dispenser/ice maker in cold ambient conditions or when the refrigerator’s internal defrosting/air circulation is insufficient.
Which refrigerators is WR49X10173 compatible with?
WR49X10173 is an OEM GE/Hotpoint/Appliance Works style part used on many GE-built refrigerators. Compatibility depends on the refrigerator model and production date, so always verify by checking your refrigerator’s model number against the part number listing from GE, an authorized parts dealer, or the parts listing where you buy the kit. Do not assume compatibility based on appearance alone.
What are the common symptoms that this heater kit has failed?
Typical symptoms include a dispenser that stops delivering water (especially in cold rooms or winter), intermittent or slow water flow from the door, visible frost or ice forming on the water tubeor water lines that repeatedly freeze at the door. If the rest of the refrigerator is cooling normally, a failed heater is a likely cause when the water line freezes.
How do you test the WR49X10173 heater to see if it is working?
First disconnect power before handling the part. With the heater removed, check continuity across the heater element with a multimeter; it should show a low resistance (not open). To verify it receives power in-service, reconnect panels, restore powerand measure the voltage at the heater connector while the refrigerator is in the condition that should call for heat (be very careful — this is live voltage testing). If the heater has continuity but there is no voltage at the connector, the fault may be the control board, wiring, or thermostat rather than the heater element itself.
Does the kit include a thermostat or mounting hardwareand how is it installed?
Kit contents can vary by supplier. Many kits include the heater element and a clip or adhesive sleeve to secure it to the water tube; some versions include a temperature sensing thermostat or connector. Installation is generally: disconnect power and water, remove access panels, attach the heater to the water tube per the kit instructions, secure wiring to the fridge harnessand replace panels. Always follow the specific instructions that come with your kit and verify what is included before starting.
What voltage does the heater use and how is it controlled?
The heater is driven by the refrigerator’s electrical system and typically operates on the appliance line voltage supplied by the control board or a temperature thermostat.In most household refrigerators this is derived from the 120 VAC supply. The control board or an inline thermostat switches the heater on only when necessary to prevent the water line from freezing.
What safety precautions should I take when replacing the heater kit?
Always disconnect the refrigerator from electrical power and shut off the water supply before starting. Avoid contact with energized terminals; if you must measure live voltage, take appropriate safety precautions or have a qualified technician perform the test.Route and secure wires so they cannot contact sharp edges or moving partsand ensure any exposed connections are insulated. Replace panels and restore power only after confirming all connections are secure and dry.
How long does the heater kit last and should I buy OEM or aftermarket?
Service life depends on usage and environment; many last several years but can fail earlier if exposed to moisture, mechanical damage, or wiring stress. OEM parts (like WR49X10173) are built to the manufacturer’s specifications and are generally recommended for best fit and reliability. Quality aftermarket parts can be acceptable if they specify compatibility and meet the same electrical and mechanical requirements. Always buy from a reputable parts supplier and confirm return policy and warranty coverage.
