To locate the exact replacement components for your 25.5 cu. ft. French-door cooling unit, reference the exploded view schematics in sections 8 through 12 of the official service manual. The interior LED light assembly (part #DA97-18003D) sits behind the right-side mullion cover–remove the single Torx T20 screw securing it before disconnecting the four-pin harness. For evaporator fan motor failure, focus on sub-assembly 3C; the blower wheel (AH45-00741A) requires a 9mm socket for removal after releasing the three retaining clips.
Door seals on this model use a three-layer gasket design–replace only complete sets (AH61-00025A for upper doors, AH61-00026A for lower) to prevent uneven cooling gaps. The dual icemaker system’s water inlet valve (part #DA97-16580A) connects via a ¼” compression fitting; shut off the household supply and purge the lines before swapping to avoid ice buildup in the freezer compartment.
Defrost heater repairs demand access via the rear panel–unplug the appliance, tilt it forward on its wheels, and remove the 11 Phillips screws to reveal the heating element (AH36-00019A). Test continuity with a multimeter before replacing; faulty units often show 0Ω resistance. Compressor start relay issues (part #DA31-00211A) typically manifest as clicking sounds–verify proper installation by ensuring the relay snaps securely into its socket without lateral play.
Control board diagnostics begin with the inverter display (part #DE92-00919A). If error code “4E” appears, check the thermistor continuity (spec: 10kΩ at 25°C)–replace if readings deviate by more than 5%. Cabinet hinge repairs require removing the top grille (held by four hidden tabs) to access the torque rods. Lubricate pivot points with food-grade silicone grease during reassembly to prevent squeaking.
Repair Manual for Model RF260: Key Component Locations
Begin by removing the lower front panel to access the evaporator fan motor. Detach the two screws securing the grill, then pivot it downward to reveal the assembly. The fan connects via a three-wire harness–label each wire before disconnecting to avoid confusion during reassembly. This component often fails silently, so test with a multimeter for continuity before ordering replacements.
Locate the defrost heater on the rear wall of the freezer compartment. It’s a glass-encased element embedded in the evaporator coil–handle with care as the filaments are fragile. Measure resistance (typically 20-40 ohms) before removing; a reading outside this range confirms failure. Replace the heater in pairs with the defrost thermostat for consistent performance.
To service the water dispenser, disconnect power and drain the reservoir. Remove the outer door panel (held by eight screws) to expose the valve assembly. The dual inlet valves–one for chilled water, one for ice–are prone to mineral buildup. Soak valves in white vinegar for 30 minutes, then flush with distilled water to restore flow rates. Inspect tubing for kinks during reinstallation.
Electrical Diagnostics
Trace the main control board behind the top rear panel. Disconnect power, then remove the five screws securing the cover. Use a multimeter to check voltage at the P1 connector: pins 1 and 2 should show 120V AC; pins 3 and 4, 12V DC. If readings differ, test the transformer and thermal fuse before replacing the board–a common failure point.
The condenser fan motor sits behind the rear access panel. Remove the single screw securing it to expose the blade and housing. Spin the blade manually to check for friction; a rough rotation indicates bearing wear. The motor draws 0.3A at 115V–verify with an ammeter. Lubricate with graphite powder (not WD-40) if noise occurs without current failure.
Replace door seals by peeling the old gasket from the groove–heat the area with a hair dryer to soften adhesive. Clean the groove with isopropyl alcohol before installing the new seal. Press firmly along the entire perimeter, then test sealing by placing a dollar bill between the door and frame; resistance should be uniform when closing.
Compressor relays sit on the left side of the unit’s base. Access them by removing the rear lower panel. The overload relay (usually black) and start relay (white) slide onto the compressor pins. Shake the relays–rattles indicate internal damage. Swap relays with known-good units if the compressor won’t start, but avoid jumper wires for testing as this risks catastrophic failure.
Identifying Core Elements in Your Cooling Unit’s Layout
Begin with the upper rear section where the compressor resides–typically a black or dark gray cylindrical or box-shaped unit. Check the schematic for label Q1 or PUMP, as this device circulates refrigerant through the system. Verify its positioning near the condenser coils, often finned tubing behind a protective grille at the bottom or back.
Locate the evaporator fan inside the freezer compartment–usually behind the rear panel. The fan should align with label FAN1 in the visual guide, positioned to blow cold air into the fridge and freezer sections. If airflow drops, examine the area for frost buildup obstructing the motor’s small blades.
- Condenser coils: Found at the base or rear, these serpentine tubes (COIL in the chart) dissipate heat. Clean them annually–dust accumulation forces the compressor to work harder, reducing efficiency.
- Temperature controls: Search for CTRL BOARD or THERMISTOR in the ice maker or fridge cavity’s upper corner. These sensors regulate cooling cycles–faulty readings cause inconsistent temperatures.
- Defrost heater: Wrapped around the evaporator (HEATER ASM in guides), this component activates to melt frost during defrost cycles. A broken heater leads to ice blockages in hours.
Inspect the water valve assembly next to the compressor if your model includes an ice dispenser. The valve–labeled SOLENOID–blocks or allows water flow to the ice maker. Corrosion on connectors disrupts water delivery, causing leaky trays or hollow cubes.
The door switches (SW1/SW2 in most schematics) trigger interior lights when doors open. These small plastic or metal protrusions mount along the door frame. Misalignment shuts off cooling even when doors are closed, wasting energy. Test by pressing each switch–lights and fans should activate instantly.
- Remove rear or lower access panels only after disconnecting power–capacitors store lethal voltage.
- Use a multimeter to confirm components match their labels: fans register ~120Ω, heaters ~30-60Ω, thermistors >5kΩ at room temperature.
- Cross-reference colors: wires in guides often match physical harnesses (e.g., red/black for power, yellow for signals).
Trace the refrigerant lines–thin, copper tubing–from the compressor to the evaporator. Kinked or corroded lines restrict flow, causing warm fridge temps. Inspect solder joints near the filter-dryer (DRYER) for oil stains, indicating leaks requiring immediate recharge.
For models with dual cooling, identify both evaporators: one in the freezer (EVAP FRZ), one in the fridge (EVAP FF). The secondary evaporator’s fan (FAN2) circulates air into the fridge zone. Blocked vents here create uneven cooling–ensure no food packages obstruct the airflow slots.
Step-by-Step Disassembly for Accessing Core Components
Unplug the appliance and relocate it to a well-lit, stable workspace with adequate clearance. Remove all food items and interior shelves, then detach the lower kick plate by pressing inward on its retaining clips–these are positioned near each corner and require firm pressure to disengage. With the plate removed, locate the drain tube and verify no residual water remains; use a towel to absorb excess moisture if necessary.
Next, extract the rear access panel by unscrewing the fasteners along the perimeter. Use a ¼-inch hex driver for the upper screws and a Torx T20 for the lower ones–count eight total: three on each side and two at the base. Store screws in a labeled container to avoid misplacement. Once removed, tilt the panel backward carefully; it secures additional wiring for the evaporator fan, which must remain connected until the control board is accessible.
Disengaging the Door Assembly
Lift the door seal from the outer lip using a plastic pry tool, starting at the top hinge and working downward. The seal is held by a tensioned wire, which can be guided out of its channel with gentle pressure–avoid excessive force to prevent tearing. Once the seal is free, remove the hinge covers by unscrewing the single Phillips screw at each hinge, then lift the door off its pivot pins. Set the door aside on a padded surface to prevent scratching the exterior finish.
With the door detached, locate the inner door liner screws–typically ten in total, recessed behind plastic caps. Pop the caps with a flathead screwdriver, then remove the liner using a 5/16-inch nut driver. Behind the liner, the foamed-in-place insulation will be visible; this material is fragile and should not be disturbed unless replacing a door sensor or heater element. If proceeding further, disconnect the wiring harnesses by releasing the tabbed connectors, noting their positions for reassembly.
| Step | Tool Required | Screws/Fasteners | Key Precautions |
|---|---|---|---|
| Kick plate removal | None (hand pressure) | 4 retaining clips | Check for water residue |
| Rear panel access | Hex (¼”), Torx T20 | 8 screws | Avoid disrupting fan wiring |
| Door seal removal | Plastic pry tool | Tensioned wire | Work from top to bottom |
| Door hinge covers | Phillips screwdriver | 2 screws | Label screws for reassembly |
| Liner extraction | Nut driver (5/16″) | 10 screws | Preserve insulation integrity |
For access to the compressor or condenser coils, slide the unit forward slightly to expose the rear grille. Remove the grille by unscrewing the six Phillips screws–two at each side and two at the base. Behind the grille, the condenser coil is secured by a retaining bracket; loosen the bracket’s two screws with a 7/16-inch wrench, then pivot the coil outward. Exercise caution: refrigerant lines may still hold pressure, and puncturing them requires professional evacuation before repair.
