Follett Freezer Temp is High – Under Counter REF5 / 00926626
Customer complaining that the Follett Freezer temp is high and has been for a few days. Found the unit temperature at 50*F. Checked all components and found they were operating normally. Installed my stubby gauges to check refrigerant pressures and found the suction pressures lower than normal. Unit discharge line and condenser were barely warm to the touch. Determined that unit was low on charge and therefore must have a leak. Returned with service gauges and nitrogen then pressured system to 125 psig. Searched for leaked using my leak detector. Unable to locate any solid detections. Doubled checked with leak bubbles and still unable to locate any leaks. Bled off nitrogen and pulled a quick vacuum. Recharged system with refrigerant per weight on data tag. Added leak dye to system. Informed client of leak issue and that we would return in a couple of weeks from now to allow leak dye to circulate and hopefully help us pin point where leak is in the system. Returned to the location and started search for leak dye. Found a little dye underneath evaporator coil. Called factory and checked the units warranty status and part availability. Checked unit charge and pressures looked normal. No need to add any additional refrigerant. Spoke with customer about findings and quoted repair. Customer said he would call us to make repair if approval was given. Unit is currently operational and temperature was at -3*F before leaving.
