    I just puchased this item. It has been running for 3 days and the cans are only cool. The bottom row is a little cooler, but definitely not chilled.

Jeremy, after the line and new filter drier is put in the high pressure side and silver soldered make sure the unit is placed in absolute vacuum for 30 to 60 minutes. It's critical that all air and moisture is remove and the charge applied on low side with out a single air bubble put back in. You may need some on hands help on this solution to get the cooler working properly, Thanks Sea Breeze

    Your welcome, Jeremy

    Yes you will have to pull it down again. First get the freon out and put the drier in the high side with the---> arrow pointing away from compressor. Then pull a long vacuum. Close low side on guage and leave the gauges for 15 Min's.(Turn off vacuum pump after you insure guages are tight) Look to see if air is leaking back into the cooler ( If guage is losing vacuum or leak in weld). If not pull another vacuum and close knob on guage low side and purge the center charge line with freon as you connect to the gauges. Open low side valve and slowly charge from low side until correct charge.Make sure high side knob and seals are good in charging lines all valves are tight and closed as not to allow outside air to enter cooler lines or the charge.

    *(note)The smaller the capillary tube the more perfect the vacuum must be! Always replace or install filter drier on an opened system! Correct amount of freon in charge! Now, I hope this gets you going, Sea Breeze

How to add refrigerant to mt27

You should check the condenser to see that it is clean. Is the compressor running? If you have a leak, putting in gas wont help. You need to look for oil on the components around the compressor, inside the cooling coil housing. Hope this helps good luck.

Yes I have a True 95 38 Beverage cooler and I bought it new 4 years ago , I have used it for 3 and 1 year it just sat not running , well I plugged it in the other day and it is only blowing warm inside and...

Could be many things... A bad thermostat, bad compressor, bad compressor start relay, refrigerant leak, moisture in the system, or even a blocked capillary tube. You would need a lot more information... mostly only the kind a technician can get by getting his hands on it. Sorry.

Head pressure high; suction pressure low. Unit not cooling

Good day,
It's a restriction.
It could be in the liquid line dryer, cap tube as well as the condenser. If it's a R134A system, it's a common problem.

In either case, the repairs can become extensive, with the factory when under warranty, authorizing, replacing the dryer, cap tube,
condenser, and many times the compressor.

Yes some cooling units don't have service ports,but you can put a piercing valve on the low side and check it but when you done take it out and repair the little hole made by the valve.Or if you have to open the system you can add a service port at the low side(suction) and if you open the system always replace the liquid line filter and when you do you can use the ones that cames with a service port to check the high pressure side.

1st check the outter coil and make sure you can shine a flash light through the coil. If not blow out with compressed air and look again. A dirty coil may be your problem.

2nd check the inside coil it may be blocked with frost - ice
3rd the fan both in and out have to be running.
4th check the door seals

you could be low on refrigerant or have a bad thermostat but eliminate all else before going to these 2 problems.
