Safety Information & Precautions

This section outlines critical safety warnings for technicians to prevent injury, electric shock, or damage to the appliance during service.

HazardPrecaution
Electrical ShockDisconnect power before servicing. Verify power is off with a voltmeter.
Refrigerant HandlingUse EPA-certified recovery equipment. Avoid open flames; refrigerant can produce toxic gas.
Sharp EdgesWear cut-resistant gloves when handling evaporator coils, sheet metal, or fasteners.
Heavy ComponentsUse proper lifting techniques or a helper when removing doors, compressors, or condensers.
Moving PartsEnsure all fans are stopped before reaching into compartments.

WARNING! Only qualified personnel familiar with refrigeration systems and electrical safety should perform service. Follow all local codes.

Model Specifications & Features

Key technical data and standard features of the WRX986SIHZ00 model.

Installation Requirements

Proper installation is critical for performance and safety. Verify all steps before powering the unit.

  1. Location: Level floor, away from heat sources, with adequate clearance (top: 1", back: 2", sides: 0.25" min).
  2. Electrical: Connect to a dedicated 120V, 60Hz, 15-amp grounded outlet. Do not use an extension cord.
  3. Water Supply (for dispenser): Connect to a cold water line with a 1/4" copper supply line and a shut-off valve. Install the water filter (if provided).
  4. Door Alignment & Handle Installation: Adjust door hinges to ensure proper seal. Attach handles per included instructions.
  5. Initial Startup: Allow unit to stand upright for 4 hours after moving. Power on, set temperatures (Recommended: Fresh Food 37°F, Freezer 0°F).

CAUTION! Incorrect leveling can prevent doors from sealing, leading to condensation and compressor overwork.

Component Locations & Access

Identification of major serviceable components and their access panels.

ComponentLocation / Access Method
Main Control BoardBehind the top grille. Remove screws securing grille.
User Interface BoardIntegrated into the external dispenser control panel.
Compressor & RelayBottom rear, behind the kickplate. Remove kickplate screws.
Evaporator Fans & CoilsFresh Food: Rear panel inside fridge compartment. Freezer: Behind rear interior panel.
Condenser Fan & CoilBottom rear, behind the lower back panel. Ensure power is disconnected.
Water Inlet ValveBottom left rear, behind the access panel.
Ice Maker AssemblyUpper left of the freezer compartment.
Temperature SensorsVarious locations: Fresh food evaporator, freezer evaporator, damper area, ambient air.

Control System & User Interface

Overview of the electronic control system, diagnostic modes, and user settings.

Control Board: The main board manages compressor cycles, defrost, fan operation, and communicates with the user interface.

User Interface (Dispenser Panel): Controls include: - Temperature Setpoints (Fresh Food & Freezer) - Filter Reset Indicator - Ice Maker On/Off - Sabbath Mode - Diagnostic Mode Entry

Entering Diagnostic Mode: 1. Press and hold "Light" and "Ice Type" buttons on the dispenser panel for 3 seconds. 2. Display will show test codes. Use "Temp Up/Down" to scroll through tests (e.g., Compressor Relay, Fans, Valve). 3. Press "Lock" button to exit.

Factory Reset: Disconnect power for 5 minutes, then reconnect.

Disassembly & Assembly Procedures

Step-by-step instructions for accessing key components. Always disconnect power first.

  1. Removing Doors: a. Open door 90 degrees. b. Remove hinge cover and hinge bolts. c. Support door weight and lift off hinges.
  2. Accessing Main Control Board: a. Remove top grille by pulling forward from the sides. b. Disconnect wire harnesses. c. Remove mounting screws to release board.
  3. Replacing Water Inlet Valve: a. Remove lower kickplate. b. Locate valve assembly. c. Label and disconnect water lines and electrical connector. d. Remove mounting bracket and replace valve.
  4. Accessing Evaporator (Freezer): a. Remove all freezer bins and shelves. b. Remove screws securing the rear interior panel. c. Carefully pull panel away to access coil and fan.

Tip: Take photos during disassembly to aid reassembly. Keep screws organized.

Electrical System & Wiring Diagrams

Reference wiring schematic (not shown in text manual; included in full PDF). Key electrical components:

Testing Components: Use a multimeter to check continuity and resistance. Refer to component-specific resistance values in the full diagram.

Refrigeration System

Details on the sealed system using R-600a refrigerant.

Dual Evaporator System: Separate cooling loops for the fresh food and freezer compartments improve humidity control and efficiency.

Key Components: - Compressor (Variable Speed or On/Off) - Condenser Coil - Capillary Tubes/Expansion Devices - Fresh Food Evaporator Coil - Freezer Evaporator Coil - Filter-Drier

Service Ports: This model may have service access valves. Always recover refrigerant before opening the system. Charge with specified amount of R-600a (weight-critical, typically ~2.0 oz).

WARNING! R-600a is flammable. No brazing on a charged system. Evacuate system thoroughly before recharging.

Diagnostics & Error Codes

Common error codes displayed or indicated by flashing lights.

Code / SymptomDescriptionProbable Cause
FF / F1 (Flashing)Fresh Food Temperature Sensor FaultOpen/short in sensor or wiring. Check thermistor resistance.
FF / F2 (Flashing)Freezer Temperature Sensor FaultOpen/short in sensor or wiring.
FF / F3 (Flashing)Ambient Temperature Sensor FaultSensor failure near control board.
Compressor not runningNo coolingCheck power, relay, overload, control board output.
Continuous runningPoor coolingLow refrigerant, dirty condenser, faulty damper, door seal leak.
Ice maker not workingNo ice productionWater supply, inlet valve, ice maker assembly, temperature too warm.

Troubleshooting Flowcharts

Structured approach to common problems.

Problem: Refrigerator not cooling. 1. Check power: Is unit plugged in? Display lit? 2. Listen: Is compressor running? Are fans running? 3. Check diagnostics: Enter diagnostic mode for error codes. 4. If compressor runs but no cool: Check condenser (clean?), evaporator fans, sealed system. 5. If compressor does not run: Check relay, overload, control board output.

Problem: Water dispenser not working. 1. Check water supply: Is shut-off valve open? Line kinked? 2. Check filter: Is it installed? Is it clogged? Reset filter indicator. 3. Listen for valve: Press dispenser paddle; do you hear a click? 4. Test valve: Use diagnostics to activate valve. Check for voltage. 5. Check for frozen water line in freezer compartment.
