The above will take you to the installation manual for your unit. This is to make sure you have set up the unit to their specs.

There are multiple things that can cause a lack of cooling. Let's cover a few of them.

1: Make sure the condenser coil under the unit is clean. You have to be able to take a flashlight and see light through the coil and fins. Be sure unit is off when cleaning. Use vacuum, compressed air, or a long, stiff bristle brush and go with the fins direction so they do not bend over.

2: The termostat may be set wrong or is not working as designed. Look for the compressor and fan on the condenser to cycle off when temp is met and on when it gets too warm. If unit is running all the time, look for frozen up evap.

3: If evap is frozen up, no air can pass through so no cooling is taking place. Air can not go through a solid block of ice. Clear ice with warm water. Again, make sure unit is off first.

4: Door not sealing or closing all the way. Seal on door should have magnets that help seal them to the door frame.

5: Again, if unit is running all the time, as in #2 above, unit may be low on refrigerant (freon). If you suspect this to be the case, have a qualified tech do the repair. Make sure he locates and repairs the leak. Adding freon without the repair means he will be back to do it a second time. The system is a sealed one and you should not have to continually add freon.

Good Luck and hope this get you going.

If you check into it further I think you will find that the units are low on freon and the coils are froze up causing the leaks....
Turn them off let them defrost and then have the correct charge placed in the system.....
They will work well, and also save you money because they will run much less...

You will need to find out why the unit is not shutting down properly....
It may be that the thermostat sensor will need to be placed in a different spot...or the temperature may just need to be raised higher...
Does the thermostat turn off the unit if the temperature is raised??? If so, then place a thermometer in the cooler and then adjust the thermostat to 38F by that thermometer and not by the t-stat calibration, it may be off even if it is new...

If the t-stat is not cycling the unit then you will need to use an electrical meter to trace out the power to the unit and find out why it is not shutting down...

The pulleys or copper tubing can be accessed by removing the aluminum siding located inside cabinet on either side. The left side contains the pulley and weightfs or left and center door, the right for right door (each held on by 4 1/4 screws) . To make the door close, simply make sure string is attached to weight, running though pulley, and attached to top of door.

    Cant get my GDM 69 to go below 40, seems to cycle fine just won't go any lower even after turning the thermostat knob

    Unplug the unit. Clean your condensing coil, the one by the compressor. Nothing fancy, just get a narrow plastic or brass wire brush and follow the lines of the coil fins. If you like, spray in some heavy duty de-greaser like you use around your restaurant and rinse thoroughly.

    Where do i find the starters for the florescent lights on a true gdm-72

    They should be located under the front access cover below the door. Under that cover there may be another smaller covered box that they may be located in.Make sure you disconnect the power source before removing any covers.

    Flourescant lights flickering

    is there a ballast or a starter? if there is a starter (little silver metal or white plastic can), then replace the transformer inside the lamp housing. if there is a ballast (long black rectangle with many wires) and you replaced that and the lamp, then there must be a power drain in the unit somewhere.

    A starter may be located in the top area inside the cooler. Not all true coolers have starters. Check the connections where the light pins slide into. Also may need new ballast.
