Thermostat defective/Short of gas/chocked/no gas.
1. Thermostat is malfunctioned-Replace it. 2. Check amps of the fridge if run amps is less than as specified, it's gas leak. 3. Keep your arm on condenser line. If it's warm, gas is there. Check slight whistling sound in freezer. If not system chocked.
For gas leak find leak and arrest it. Then vacuum and do gas charging.
For chocked system, release all gas and flush out the system. Replace filter drier and vacuum and do gas charging. Helpful?
So first thing you try is , perform,
manual defrost reset procedure.---------
The manual defrost
reset procedure is as follows : ----
First unplug the unit from main power outlet. Then empty whole unit
completely. Then keep both the doors open. Wait for 24 hours. All the ice
collected on the coils and in the freezer section will get melted.
Clean the water from the sections. Then Connect the power cord of the unit to
main power outlet after 24 hours/.Then set the temperature to normal in both
fridge and freezer section. Then check,if same frost is getting collected, then its defrost problem,. If it's again
building up ice that means the unit is not defrosting. It's starting the
cooling procedure, and then while defrosting, it's not working. The defrost
assembly consists of three main parts. The defrost thermostat, the defrost
heater and defrost board. Any of the one is not functioning. When thermostat
sense the maximum cooling, it triggers the defrost heater to start heating and
this defrosts the ice collected on the coils and the system works. Both
thermostat and heater are controlled by defrost board. First the
thermostat and defrost heater to be checked, if both check ok by meter and
visually, then its defrost board causing the problem. You can get
required parts from from online sites like:

should help.Thanks.Helpmech.
Oncce the fridge was shut off and left for a while the cooling had come back . If frost is seen it is a good indication as the compressor is working with sufficient gas within.
If after about 6 hours you observe cooling it is possible that the defrost timer is faulty.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge.
However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
replace the defrost timer, heater or thermostat one you have confirmed to eliminate one by one.
If there is no cooling on the fridge but the freezer is cooling then the compressor and gas pressure seems good. So to check the set for blocks in the ducts we must shut off the fridge.Keep it off while you clean and check the evaporator for frost. If frost is seen it is a good indication as the compressor is working with sufficient gas within.
Now after about 6 hours plug in the fridge to start. Observe cooling to happen in about one hour and ice to from under three hours.
Earlier make sure that the thermostat was set to normal mode for freezer and fridge. However if Ice forms then observe the fridge for about 24 hours for cooling to continue and the fridge to cut off . If not the auto defrost timer, or the thermostat must be checked.
The fan making noise can be due to frost build up .If defrost timer works but frost keeps forming check while the compressor shuts if the heaters are working, check continuity of the heaters.
Do not set thermostat up to max but keep it to normal .So try this test from the outside and make your observations so that we come to the solution.
