If you mean by low you mean number 1? This would mean the thermostat is bad. Number 9 would freeze everything anyway. I'm leaning towards a bad thermostat. Email if you want a thermostat [email protected]

SOURCE: We have a Coke Cooler (True)-- not cooling, icing over

thes are pretty well built unit, did you check th see is the evaporator fan motor is running at full speed" All that you may have to do is clean the evaporator and maybe change out the evaporator fan motor. True has a special one and you cost should be arouud 75 dollars wholesale.

SOURCE: TRUE COOLER COMPRESSOR CYCLES ON 45 SECONDS AND OFF FOR 2 MIN.

The unit has a temperature swing adjustment screw located behind the thermostat plate.If you remove the knob and the face plate you will see it,It can be adjusted there.It may also be the thermostat bulb is going bad or touching something and giving a false signal to the compressor.

SOURCE: I've set the freezer as low as it will go but it

The evaporator coil behind the cover on the back wall inside the freezer will ice up under normal conditions. Every 8 to 10 hours for around 20 minutes the defrost timer (or in most newer models the electronic adaptive defrost control) will turn the defrost heater on to melt the built up ice. There is a defrost thermostat which prevents the heater from overheating the freezer by breaking the heater circuit when the temp reaches close to 32 degrees F. The entire cooling system shuts off during the defrost cycle and starts back when the timer advances through the cycle.

If this ice is not melted it will continue to build up until the air can’t flow over the coil to circulate the cold air through the freezer and into the fridge. The temperature change in the fridge is usually noticed first followed by the freezer.

If the defrost thermostat is bad, it can prevent the heater from coming on OR it won’t turn the heater off when it gets too warm. It is clamped to the evaporator coil at the top to sense the temp. If it appears to be misshapen it is bad.
With an ohm meter it should show continuity when cold and none when warm.
You can also bypass(disconnect the two wires plugged into it and twist them together) the thermostat to see if the heater comes on then. If it does then you know the thermostat is bad and needs replaced.

The defrost heater is located on the evaporator. It is in a tube which is at the bottom and can also go up the sides of the evaporator. On some types you can see a burnt spot if it’s bad. With an ohm meter it should show continuity from end to end when disconnected from the wiring in the freezer. You can also test the wiring for voltage when it’s in the defrost mode.

If you have a defrost timer you can test it. It can be located under the fridge behind the kick panel on the front. Some are in the fridge with the controls at the top. You can turn the defrost timer till it clicks and everything shuts down. The heater should now come on. If it does, replace the timer because that means the timer is not running. If it doesn't, check the heater and defrost thermostat. Turn the timer again till everything starts back up to end the defrost cycle.

If you have an adaptive defrost control instead of a timer, replace it if the heater and thermostat test good. It is located in the fridge with the controls in some models and on the back in others. You can post your model number into one of several appliance

LG French door refrig 766-what should I set refrig temp &. Then the freezer—- I know it will change to internal— I just need to ser temps’

I would set the fridge in the middle, check it in a couple hours and see what the temperature is. I like my fridge too be at 36 degrees. Adjust the temperature control as needed to get the temperature to what you like. Do the same with the freezer, I like my freezer to be around 28 degrees. My big freezer I keep at about 10 degrees.

Cooler wavers between 35 and 45 degrees.....even after turning the controls to colder. Would this be the thermostat?

Probably... OK I am going to fill you in on something here that almost no one knows. The True coolers all use a thermostat that reads the coil temperature and has no idea what the box air temperature might be. They are all pretty much the same but have a few different variations. For most beverage coolers though they are getting the coil down to around 13-15 degrees and then shut off and stay off until the coil gets back up to 38-40 degrees.This means that the air temperature can be anywhere from 23 to 50 degrees at any given moment but the product temperature is going to average out in the middle. If the box is full no problem the temperature swing will not be anything like this because the product will keep the temperature more stable. If the box is empty you will need to put SOMETHING in there to help stabilize the temperature before panicking. 3 or 4 gallons of water will do. Also if you want to sleep better at night put a thermometer in a glass of water in the cooler to get a better idea what your product temperature really is and don't put too much faith in the cheap dial thermometer mounted to the outside of the box. Oh and set the dial on 5 and if that doesn't work the thermostat could be a problem... they are the weak link in these units.

Thermostat or start relay is defective and causing the compressor and fans to run all the time. Here is a manual for all models=> HERE

Coils keep freezing up, and temperature in cooler won't go lower than 44 degrees. just installed new thermostat.

Hi,
The refrigerant system is low on charge....you will need to have the leak fixed and the system recharged.

Arctica pss29ngna Fridge is getting too cold

Hi, On any model of temperature controlled box, the only thing that is wired into the system to control the temperature is the thermostat. Commercial boxes can be controlled by a low and high pressure control. If the temperature will not get above what you are saying, the only thing that can be at fault is whats sensing the temperature which is the thermostat control. If you are not able to change the setting to raise the temp, its not doing its job and needs to be changed out.
Sincerely,

Freezeing up, not cooling

Without knowing if it a freezer or a cooler I will have to guess. Could be caused by a few things. I'll list them in order of the one I think is the most common reason.

Cooler
  1. Door gaskets or someone left door open for a time.
  2. Thermostat set to low.
  3. Low freon
  4. expantion valve out of adjustment or needs replaced
Freezer
  1. Defrost not working (Will have heaters with a timer)
  2. Low on freon or expantion valve

The beverages in my True refrigerator are frozen

Definitely a thermostat problem. Make sure that it is set on #3, make sure you have something in the box to provide a constant load (if you are worried about product freezing just put several gallons containers of water in there), set a thermometer on a shelf and let it run for several hours. Temperature should run 35-40f If it still freezes I recommend changing the thermostat. Not the easiest job on a True but the only real option. If it is too warm then raise the setting to #4 and run for several hours more and double check the temperature. It is normal for these box temperatures to "swing" quite a bit especially if empty. The thermostat actually senses coil temperature and not unit air temperature. Typically it cycles off when the coil reaches around 14f and then back on when the coil gets to around 38-40f.

Is It A Cooler or a Freezer?

With no heaters or defrost timer, it is most likely not a freezer unless someone removed all that. As best as I can tell, I can not find anything that equates to the temperature and pressures you related to. It could be either low on Freon or the R-12 has been removed and an alternate Freon installed to replace it. Hope this helps.
