TROUBLESHOOTING Possible causes and solutions PROBLEM COMPRESSOR WILL NOT START POSSIBLE CAUSE SOLUTION NO VOLTAGE IN THE ELECTRICAL SOCKET USE A VOLTMETER TO CHECK THE VOLTAGE THE ELECTRICAL CONDUCTOR OR WIRES MAY BE CUT USE AN OHMMETER, TO CHECK FOR CONTINUITY DEFECTIVE ELECTRICAL COMPONENTS SUCH AS: THERMOSTAT, RELAY, THERMAL PROTECTOR, ETC.
PROBLEM POSSIBLE CAUSE SOLUTION THE TEMPERATURE IS NOT COLD ENOUGH THE REFRIGERATOR HAS BEEN PLACED AT AN INADEQUATE LOCATION THE UNIT MUST NOT BE NEAR STOVES, WALLS THAT ARE EXPOSED TO THE SUN, OR PLACES THAT LACK SUFFICIENT AIR FLOW THE REFRIGERATOR HAS BEEN USED IMPROPERLY THE SHELVES MUST NEVER BE COVERED WITH ANY TYPE OF PLASTIC OR OTHER MATERIAL THAT WILL BLOCK THE CIRCULATION OF COLD AIR WITHIN THE REFRIGERATOR THE REFRIGERATOR HAS BEEN OVERCHARGED WITH THE REFRIGERANT GAS CHE
PROBLEM EXTREME CONDENSATION INSIDE THE REFRIGERATOR POSSIBLE CAUSE THERMOSTAT’S AMBIENT SENSOR IS LOOSE OR INSTALLED IMPROPERLY THE OUTSIDE ENVIRONMENT’S RELATIVE HUMIDITY IS VERY HIGH (OVER 75%) THE REFRIGERATOR DOOR WON’T SHUT COMPLETELY NO ILLUMINATION SOLUTION CORRECTLY FASTEN THE THERMOSTAT’S AMBIENT SENSOR THIS TYPE OF OCCURRENCE IS CAUSED BY LOCAL CLIMATIC CONDITIONS AND NOT BY THE REFRIGERATED UNIT CHECK THE DOOR AND/OR THE MAGNETIC GASKET.
REFRIGERATION SYSTEM Component Description COMPRESSOR: The compressor is a factory sealed unit located underneath (outside) the cooling cabinet. This pump is activated by a motor which draws low pressure vapor (refrigerant) from the evaporator. It then compresses the gas and forces it into the condenser at a high pressure. STARTER RELAY: The starter relay is attached on one side of the compressor box. The compressor motor has two windings: one for starting and another for running.
REFRIGERATION SYSTEM Component Description EVAPORATOR: The evaporator is located inside the cooling cabinet. As the gas flows at a low pressure through the evaporator, it absorbs serpentine and removes the heat from inside the cabinet. EVAPORATOR FAN MOTOR: This device produces the required circulation of air through the cooling cabinet as well as over the surface of the evaporator’s serpentine thermal exchange area. This fan motor runs continuously.
THE REFRIGERATION CYCLE 1. As the temperature inside the cooling compartment increases, it is detected by the thermostats’ sensor. The thermostat then turns the compressor and the condenser motor on once the programmed temperature is reached. 2. The compressor recirculates the refrigerant throughout the system by drawing the refrigerant gas at a low vapor pressure from the evaporator. Then it compresses the refrigerant and forces it into the condenser. 3.
