Ac cooling insufficient

Check the Control Settings:
Ensure that the temperature settings for both the fridge and freezer compartments are appropriately configured. Sometimes incorrect settings can lead to cooling problems.
Make sure the fridge is not in demo mode. If it is, disable demo mode by referring to your user manual.

Inspect the Door Seals:
Damaged or worn-out door seals can cause cold air to leak out, resulting in insufficient cooling in the fridge compartment. Inspect the door seals for any cracks, tears, or gaps.
If you find any issues, consider replacing the door seals.

Evaporator Coil and Fan Check:
The evaporator coils in the fridge play a crucial role in cooling. If they are frozen or malfunctioning, it can affect cooling.
Similarly, check if the fan responsible for distributing cold air inside the fridge is working correctly.

Reset the Refrigerator:
Sometimes a simple reset can resolve cooling issues. Unplug the fridge from the power source for a few minutes, then plug it back in.
Observe if there's any improvement in cooling after the reset.

Compressor Overheating:
You mentioned that the compressor is very hot. An overheated compressor can impact cooling.

Allow the compressor to cool down completely before switching the fridge back on.

this will be from the head pressure being excessive as the gas is not being converted to liquid in the condenser. The main reason being that there is insufficient air passing through the condenser from the ac fan not working. There has to be an extra fan in front of the condenser to maintain air flow at all times the ac is operating. The second reason is excessive amount of gas in the system. Have the pressures checked by an accredited ac shop.

by running out of fuel there is damage done to the little plastic gears in the fuel pump. I would say that the misfires are now the result of insufficient fuel supply and pressure to run the injectors. IT would also account for why there is insufficient power to run the ac compressor

Hi.

Most common problems with refrigerator are either caused by a defective defrost system or by defective compressor motor assembly.

Check if the coils at the back are frozen. In that case the problem is the defrost system. Even if coils are not visibly frozen, try doing a complete defrost and see if the fridge will restart cooling. You can follow the troubleshooting that I just wrote on this page.

If problem is not the defrost system, check if the compressor is starting. If the compressor is not starting at all or is humming and slow to start, then you may need to replace the compressor starter kit or the compressor itself. The starter kit comprises a capacitor and a relay connected directly to the motor. The motor is usually under warranty for many years (up to 12). Call manufacturer if you think that the problem is the motor.

If the motor instead works, stays always on, and defrost has just been performed manually, then there may be insufficient gas pressure. This usually happens with old appliance and requires a repair call.

Modern refrigerators may also deliver insufficient cooling because of a defective ventilation (damper) system, or because of defective temperature electronic control. The most common faults occurring with all refrigerators are still fixed troubleshooting defrost system and compressor starter kit.

hi there,
there are several test to be done and analysis on trouble shooting ac performance.if the ac run smoothly but insufficient cooling effect was taken after recharching factors can be obtain in poor performance of compressor,clogging of tubes mostly on capillary tube and expantion valve.this main factor
contribute on ac in sufficient cooling.compressor performance can check the on the discharge valve by mounting a hi side pressure gauge and check the lost compression effeciency.while the compressor is running if it can discharge a pressure higher than the operating pressure w/o losses on psg. you have good
compressor performance.but if can not maintain a operating pressure you replace compressor.if the compressor is good check the capillary tubing by purging and cleaning the system,obstruction can't expand the freon inside your evaporator,have a nice day don't forget to fix my rate.also recharge exact amount freon on the system don't exceed.poor refrigeration was the result,no cycle will occured.

is the fan running

Most likely problem is lack of refrigerant in the AC system. AC compressors need a minimum amount of refrigerant to function. If your system has a small leak, you may have insufficient refrigerant. Have your system recharged (most garages will do it for under $100) to get your AC working again. Best of luck.

This is only low freon. If the bottom coils freezes and frost over, you don't have enough freon to travel as liquid back to the compressor and boils right there and past this only cool gas .I'll advise you to get this fixed before you loose a compressor due to locking up by not cooling the compressor properly. Get in touch with an Ac man. this should only cost around $100:00

the coil is inside the front of compressor the electrical connector on the compressor that the coil for a block orifice tube forget it high pressure would go up pass 3oo untill pressure sensor cut the compressor you have to look if you have power and ground when the compressor not working or a bad sensor near the dryer 12volt positive bypass that switch i think that what it is, wire beeteen the 2 therminal send power to compressor the pressure that you have mean the ac system get cool off our low side is 40 not block you said 100 somthing the warmer it is the high side is higher our pressure look good its probably a sensor problem look at it pierre

1989 year would indicate the system uses the Old CFC R12 refrigerant. 70 PSI equals about 70°F . This is not enough pressure difference to give you any cooling. Sounds like your compressor has bad valves. Replace compressor.
