GDM-26 humidity very high

You mean 'low as it can go', talking temperature not numbers. The temperature is too high. You need a refrigeration engineer. You either need a top up of gas or the thermostat has failed. They are great fridges, I have had lots of them in my career.

Replace the thermal/starter relay. It is located on the side of the compressor. It clicks like if you unplugged the unit and plugged it back in quickly causing an over load on the compressor due to the high side still having high pressure and have to wait for a couple of minutes before you plug it in. The relay is at fault. Hope This Helps.

Should be under the wiring cover behind the vent slats.

Faulty thermostat, the thermostats are cheap and wear out easy

Hello Margarito539,

I understand that you purchased a True GDM-41 merchandise refrigerator and you are having a problem with the temperature. The thermostat you are currently using is an in-line thermostat and is not the proper thermostat for the unit I would suggest that you follow the below link and purchase the proper thermostat for the unit. http://restaurant-equipment-parts.com/part/true/800393 the cost is $36.98 and is an OEM part.

You also may need a service tech to check out the freon in the unit. The unit uses 134A freon and must be within a few ounces of charge other wise it will not work properly. As the unit is keeping it 60 degrees, before you do anything make sure that you can hear the compressor running as this is not a cheap fix, however may be worth the cost for the unit you have. The compressor should be humming if it is not and the unit has been plugged in for a while, unplug for about thirty minutes and let the compressor cool. Once thirty minutes has passed plug in and see if the compressor is humming.

After checking the compressor you have two choices if it is humming call a service tech and have them check the freon charge and thermostat or change the thermostat and see if the compressor starts cooling the unit. If the compressor is working then the box is well worth fixing, if the compressor is not working you need to decide if it is worth fixing. A used unit with a one year parts and labor warranty costs $2100 so the repair should not cost over $1000 to be economical.

Thank you for choosing FixYa.com

NONE. This is a common complaint from customers who buy commercial units for use in residential atmosphere or quiet stores. These units are made for noisy commercial kitchens, convienience stores, etc.

there is a leak of gas in the system,must see where the leak is, repair it then fill the gas,

Unplug the unit & remove the plate holding the thermostat. The capillary for the thermostat will go into a very small tube that runs into the evaporator coil. You will probably not be able to see the tube but will have to feel for it and get a good orientation for where it is located before you pull the capillary out. Try to measure the amount of capillary in the tube as you pull it out so you know how far you have to push the new one in and put some kind of tape or mark on the new capillary before you try to push it in. you might have to soap up the capillary to get it to slide easier.
