TROUBLESHOOTING CHARTS TROUBLE UNIT WILL NOT RUN. COMMON CAUSE REMEDY Blown Fuse. Check power for “live” circuit. If outlet is “dead” but building has power, replace the fuse. Try to determine the cause of the overload or short circuit Low Voltage. Check outlet with voltmeter. Should check 115V plus or minus 10%. If circuit is overloaded, either reduce load or have electrician install separate circuit. If unable to remedy any other way, install auto-transformer. CABINET TOO WARM.
TROUBLE CABINET RUNS CONTINUOUSLY. COMMON CAUSE REMEDY Not enough air circulation around cabinet or circulation is restricted. Relocate cabinet or provide proper clearances around cabinet. Remove restriction. Cooling large quantities of product or heavy loading. Explain to customer that heavy loading causes long running time. Refrigerant charge undercharged or overcharged. Check, evacuate and recharge with proper charge. Room temperature too warm. Ventilate room as much as possible.
TROUBLE UNIT RUNS TOO MUCH. COMMON CAUSE REMEDY Abnormally high, heavy use of cabinet. Heavy usage requires more operation Check usage and correct or explain. Shortage of refrigerant. Unit must run longer and will operate at a lower than normal suction pressure. Put in the normal charge and check for leaks. Overcharge of refrigerant. Excessively cold or frosted suction liner results in lost refrigeration effort. Remove excess charge.
COMPRESSOR – TROUBLESHOOTING CHARTS TROUBLE WON’T START. NO HUM. WON’T START. HUMS INTERMITTENTLY. (cycling on protector) COMPRESSOR STARTS – MOTOR WON’T GET OFF STARTING WINDING. 98 COMMON CAUSE REMEDY Open line circuit. Check wiring, fuses, receptacle. Protector open. Wait for reset—check current. Control contacts open. Check control, check pressures. Open circuit in stator. Replace stator or compressor. Improperly wired. Check wiring against diagram. Low line voltage.
TROUBLE COMPRESSOR STARTS & RUNS BUT CYCLES ON PROTECTOR. STARTING CAPACITORS BURNT OUT. RUNNING CAPACITORS BURNT OUT. RELAYS BURNT OUT. TROUBLESHOOTING COMMON CAUSE REMEDY Low line voltage. Bring up voltage. Additional current passing through protector. Check for added fan motors and pumps connected to wrong side of protector. Suction pressure too high. Check compressor for proper application. Discharge pressure too high. Check ventilation, restrictions and overcharge. Protector weak.
FLUORESCENT LAMP – TROUBLESHOOTING CHARTS The manufacturer uses standard fluorescent lamps in ail of its applications. Standard one- and two-lamp ballast circuits are used. Replacement lamps should be purchased over the counter from a local electrical wholesaler. The table below indicates general problems that may be encountered with fluorescent lighting applications, possible causes, and corrective maintenance suggestions. TROUBLE NORMAL END OF LIFE. Lamp won’t operate.
TROUBLE NO STARTING EFFORT OR SLOW STARTING. COMMON CAUSE REMEDY Open lamp cathode circuit due to broken cathode, air leak, or by open weld. If open, circuit is shown by continuity test or viewing end of bulb against a pinhole of light. Replace lamp. Wrong lamp type used. Replace with lamp type indicated in owner’s manual. Starter at end of life. Replace starter. Starter sluggish. Replace starter. Ballast installed not supplying the specified electrical values.
