Sears 580.75184 air conditioners troubleshooting

ProblemSolution
THE AIR CONDITIONER WILL NOT OPERATE.
Wall plug disconnected.Push plug firmly into wall outlet.
House fuse blown or circuit breaker tripped.Replace fuse with time delay type or reset circuit breaker.
MODE selector is OFF position.Turn MODE selector to the desired COOL setting.
Unit was turned off and then on too quickly.Turn unit off and wait 3 minutes before restarting.
TEMP Control set warmer than room temperature.Turn TEMP Control clockwise to a cooler setting (higher number).
The current interrupter device is tripedPress the RESET button located on the power cord plug
If the RESET button will not stay engaged, discontinue use of the air conditioner and contact a qualified service technician.
AIR FROM UNIT DOES NOT FEEL COLD ENOUGH.
MODE selector in LOW COOL position.Turn selector to HIGH COOL position
TEMP Control set too warm (lower number).Turn TEMP Control clockwise to a cooler setting.
Room temperature below 70°F (21 °C).Cooling may not occur until room temperature rises above 70°F (21CC).
Temperature sensing tube touching evaporator coil, located behind front grille.Straighten tube away from evaporator coil.
THE AIR CONDITIONER COOLING, BUT ROOM IS TOO WARM - ICE FORMING ON COOLING COIL BEHIND FRONT GRILLE.
Outdoor temperature below 70°F (21 °C).To defrost the coil, set selector to FAN position. Then, turn TEMP control counterclockwise to a warmer setting.
Air filter may be dirty.Clean filter. To defrost, set selector to FAN position.
TEMP Control set too cold for night-time cooling.To defrost the coil, set selector to a FAN position. Then, set the MODE control at FAN position or “High Cool" with the TEMP control to a warmer position.
THE AIR CONDITIONER COOLING, BUT ROOM IS TOO WARM.
Dirty air filter - air restricted.Clean air filter.
TEMP Control set too warm.Turn TEMP control clockwise to a cooler setting (higher number).
Front of unit is blocked by drapes, blinds, furniture, etc. Air distribution is restricted.Clear blockage in front of unit.
Doors, windows, registers, etc. open. Cold air escapes.Close doors, windows, registers, etc.
Unit recently turned on in hot room.Allow additional time to remove stored heat from walls, ceiling, floor, and furniture.
THE AIR CONDITIONER TURNS ON AND OFF RAPIDLY.
Outside temperature is extremely hot.Set MODE on HIGH speed to bring air past cooling coils faster.
NOISE WHEN UNIT IS COOLING.
Sound of fan hitting water - from the moisture removal system.This is normal when humidity is high. Close doors, windows, and registers.
Window vibration - poor installation.
WATER DRIPPING INSIDE ROOM WHEN UNIT IS COOLING.
The air conditioner is improperly installed.Tilt air conditioner slightly to the outside to allow water drainage.
WATER DRIPPING OUTSIDE WHEN UNIT IS COOLING.
The unit is removing large quantities of moisture from humid room.This is normal during excessively humid days.

COMPLAINTCAUSEREMEDY
Fan motor will not run.No powerCheck voltage at outlet. Correct if none.
Power supply cordCheck voltage to rotary switch. If none, check power supply cord. Replace cord if circuit is open.
Rotary switchCheck switch continuity. Replace switch if defective.
Wire disconnected or connection looseConnect wire. Repair or replace loose terminal.
Capacitor. (Discharge capacitor before testing.)Test capacitor.
Replace If not within ±10% of manufacturer's rating. Replace if shorted, open, or damaged.
Will not rotateFan blade hitting shroud or blower wheel hitting scroll. Re-align assembly.
Units using slinger ring condenser fans must have 0.22-0.25 inch clearance to the base. If it is the base, shim up the bottom of the fan motor with mounting screw(s).
Check fan motor bearings; if motor shaft will not rotate, replace the motor.
Fan motor runs.Revolves on overload.Check voltage.
If not within limits, call an electrician.
Test capacitor.
Check bearings. Does the fan blade rotate freely? If not. replace fan motor.
Pay attention to any change from high speed to low speed. If the speed does not change, replace the motor.
Fan motor noise.FanIf cracked, out of balance, or partially missing, replace it.
BlowerIf cracked, out of balance, or partially missing, replace it.
Loose set screwTighten it.
Worn bearingsIf knocking sounds continue when running or loose, replace the motor. If the motor hums or noise appears to be internal while running, replace motor.
Compressor will not run. fan motor runs.VoltageCheck voltage. . If not within limits, call an electrician.
WiringCheck the wire connections; if loose, repair or replace the terminal.Check the wire connections; If not according to the wiring diagram, correct the connections.
Rotary SwitchCheck for continuity. Replace the switch if the circuit is open.
ThermostatCheck the position of knob. If not at the coldest setting, advance the knob to this setting and restart the unit.
Check the continuity of the thermostat. Replace the thermostat if the circuit is open.
Capacitor (discharge capacitor before servicing.)Check the capacitor.
Replace if not within ±10% of manufacturer s rating, replace if shorted, open, or damaged.
CompressorCheck the compressor for open circuit or ground. If open or grounded, replace the compressor.
OverloadCheck the compressor overload if externally mounted. Replace if open. (If the compressor temperature is high, remove the overload, cool and retest.)
Compressor cycles on overload.VoltageCheck the voltage. If voltage is not within these limits, call an electrician.
OverloadChock overload, if externally mounted.
Replace if open. (If the compressor temperature Is high, remove the overload, cool, and retest.)
Compressor cycles on overloadFan motorIf not running, determine the cause. Replace if required.
Condenser air flow restrictionRemove the cabinet, inspect the interior surface of the condenser. If restricted, dean carefully with a vacuum cleaner (do not damage fins) or brush. Clean the interior base before re-assembling.
Condenser fins (damaged)If the condenser fins are closed over a large area on the coil surface, head pressures will increase, causing the compressor to cycle. Straighten the fins or replace the coll.
CapacitorTest the capacitor.
WiringCheck the terminals. If loose, repair or replace.
Refrigeration systemCheck the system for a restriction.
Insufficient cooling.Air filterIf restricted, dean or replace.
Unit undersizedDetermine if the unit is properly sized for the area to be cooled.
Excessive noise.Blower or fanCheck the set screw, or clamp. If loose or miss- ing, correct. If the blower or fan is hitting scroll or shroud, rearrange the air handling parts.
Copper tubingRemove the cabinet and carefully rearrange the tubing not to contact the cabinet, compressor, shroud, and air guide.
