How to Fix Kenmore Refrigerator Error 6 BLINK
Problem: Compressor overload or start system failure (795 series flash code)

How to Fix Refrigerator Error
1. UNPLUG unit for 30 minutes to allow compressor thermal overload to reset.
2. Restore power and listen for compressor attempting to start (brief hum then shutdown indicates overload).
3. Remove rear access panel to access compressor.
4. Replace start relay/overload kit first (least expensive component).
5. If compressor still won’t start, test compressor windings for shorts/opens (requires multimeter).
6. If windings good but compressor locked (won’t rotate shaft with screwdriver), install hard start booster capacitor as temporary fix.
7. If windings shorted or compressor seized permanently, requires sealed system repair by licensed technician (refrigerant handling required).
8. NEVER operate compressor with hard start device for >30 days – causes permanent damage.

Problem: Evaporator fan motor failure or wiring fault preventing communication with main control board

How to Fix Refrigerator Error
1. Unplug refrigerator for safety.
2. Remove freezer rear interior panel to access evaporator assembly.
3. Inspect fan blade for ice obstruction or physical damage.
4. Disconnect fan motor harness and test resistance: should read 50-200Ω across motor terminals.
5. If open/infinite resistance, replace evaporator fan motor WPW
6. Check wiring harness between fan and main control board WPW10868991 for pinched wires or corroded connectors at J2 connector.
7. Reassemble and verify fan operates during cooling cycle.
8. Clear code by pressing Door Alarm + Freezer Temp Down for 3 seconds.

How to Fix Maytag Refrigerator Error SY CF
Problem: Condenser fan motor failure or wiring fault interrupting communication with main control board

How to Fix Refrigerator Error
1. Pull refrigerator forward and unplug.
2. Remove lower rear access panel.
3. Locate condenser fan motor (mounted near compressor).
4. Inspect for dust/debris blocking blades – clean condenser coils thoroughly first.
5. Disconnect motor harness and test resistance: 50-150Ω indicates good motor.
6. If motor seized or open circuit, replace condenser fan motor WPW
7. Check voltage at harness: should read 120VAC when compressor runs. No voltage indicates failed relay on main control board W
8. Reinstall panel and verify fan runs when compressor activates.

How to Fix Maytag Refrigerator Error SY IC
Problem: Ice maker communication failure due to faulty ice maker module, wiring harness damage, or control board issue

How to Fix Refrigerator Error
1. Unplug refrigerator.
2. Remove ice bin and inspect ice maker mold for jammed cubes – clear any obstructions.
3. Locate ice maker module (typically upper freezer wall).
4. Disconnect harness and inspect for corrosion/water damage at connector pins.
5. Test ice maker thermostat continuity: should close below 15°F.
6. Manually advance ice maker by inserting insulated screwdriver into test terminals to verify harvest cycle operation.
7. If no response, replace ice maker assembly WPW
8. If ice maker tests good but code persists, check wiring harness WPW10312695 between ice maker and main board.
9. Last resort: replace main control board W10868991 after verifying all other components.

How to Fix Maytag Refrigerator Error SY CE
Problem: Communication error between user interface board and main control board during power-up sequence

How to Fix Refrigerator Error
1. Unplug refrigerator for 15 minutes to reset electronics.
2. After reboot, if code returns: remove kickplate grille and locate main control board (rear lower compartment).
3. Inspect all wire harness connections – especially J1 (power) and J7 (UI communication) – for loose/corroded pins.
4. Disconnect and reconnect each connector 3 times to clean contacts.
5. Check continuity of communication wires (typically white/red pair) between UI board WPW10366217 and main board W
6. Test UI board output: with multimeter on DC voltage, measure between J7 pins 1-2 while pressing display buttons – should fluctuate 3-5VDC.
7. If no signal, replace UI board.
8. If signal present but main board doesn’t respond, replace main control board W
9. After replacement, MUST program board using model-specific code from serial plate (e.g.,
10. via Door Alarm + Freezer Down key sequence.

How to Fix Maytag Refrigerator Error SY RC
Problem: Relay control fault on main board – compressor or damper relay stuck open/closed causing temperature regulation failure

How to Fix Refrigerator Error
1. Unplug unit.
2. Remove rear lower access panel to expose main control board W
3. Visually inspect board for burnt components near relay locations (K1 compressor relay, K2 damper relay).
4. With power restored briefly (use extreme caution), measure voltage at compressor terminals during cooling demand – should read 120VAC when relay energizes.
5. If no voltage but board receives proper input signals, relay has failed internally.
6. Check damper operation in fresh food section: should open/close during temperature changes. Stuck damper indicates failed damper motor WPW10662480 OR relay controlling it.
7. Replace main control board W10868991 if relay tests faulty.
8. IMPORTANT: After replacement, enter programming mode (Door Alarm + Freezer Down 3 sec), input correct program code from serial plate sticker, then press Freezer Down until code flashes to save. Failure to program correctly causes PE0000 error.

How to Fix Maytag Refrigerator Error SY E2
Problem: Freezer thermistor out of range – sensor reading implausible temperature (< -25°F or > 80°F) indicating open/short circuit

How to Fix Refrigerator Error
1. Unplug refrigerator.
2. Locate freezer thermistor: behind rear interior panel near evaporator coils (small white sensor clipped to evaporator tubing).
3. Disconnect thermistor harness.
4. Measure resistance at room temperature (70°F): should read 8,000-10,000Ω. At 32°F: ~7,964Ω. At 0°F: ~23,345Ω.
5. If reading infinite (open) or 0Ω (short), replace thermistor WPW
6. If resistance within spec, check wiring harness continuity back to main board J3 connector – look for pinched wires near hinge areas.
7. If wiring good but code persists, test defrost thermostat WPW10316428 (clipped to evaporator) – should read closed below 40°F.
8. Last resort: main control board W10868991 has failed ADC circuit – replace board and reprogram.
