Frigidaire FFTR1835VW Refrigerator Service Manual

The Frigidaire FFTR1835VW is an 18.3 cu. ft. garage-ready top-freezer refrigerator with white finish, featuring adjustable interior storage, humidity-controlled crisper drawers, and ENERGY STAR® certification for efficiency. This service manual provides technical data, diagnostics, wiring diagrams, component testing, and parts information for qualified technicians. Always disconnect power before servicing. Refer to the service data sheet for detailed procedures. Below are the key sections.

Safety and General Information

• Caution: All electrical parts and wiring must be shielded from torch flame. Do not allow torch to touch insulation; it will char at 200°F and flash ignite at 500°F. Excessive heat will distort the plastic liner.
• Power: 115 VAC (127 VAC max); grounded outlet required.
• Refrigerant: R600a; manual defrost, top freezer.
• Safety Note: Information for qualified repair personnel only. Disconnect power cord before servicing. Return green grounding wires to original position if removed.
• Important: Check for pinched or damaged wires before replacing components. Contact TID before replacing main control board.

Diagnostic Modes and Error Codes

Error Codes

• No Digital Display: Mechanical controls; no error codes
• Overload Trip: Compressor protector trips if amps exceed rating
• Defrost Timer: Advance to test defrost cycle

Diagnostic Modes

• Defrost Test: Advance defrost timer to defrost position; heater should energize, thermostat opens at 60°F
• Fan Test: Run compressor; fans should operate
• Compressor Test: Check voltage at compressor terminals; start relay clicks

Wiring Diagrams Summary

Refer to Wire Diagram for full schematic. Key connections:

• Power: Black (hot), white (neutral), green (ground)
• Compressor: Connected via PTC relay and overload protector
• Defrost: Heater in series with thermostat and timer
• Fans: Evaporator and condenser fans parallel to compressor
• Light: Door switch in series
• Grounds: Cabinet and chassis

Troubleshooting

• Not Cooling: Check power, thermostat settings, door seals, vents; ensure level. Test compressor windings and start relay.
• No Defrost: Test defrost timer, heater continuity, thermostat operation.
• Frost Buildup: Check door seals, defrost system; ensure proper air flow.
• Noisy Operation: Normal compressor hum; level unit; check for loose parts or fan issues.
• Light Not Working: Check bulb and door switch.
• Door Not Closing: Level refrigerator; check hinges and seals.
