My refrigerator is not cooling on the refrigerator side

There are so many things that can make your fresh food side not cool. Usually, it is a frosted up evaporator, which is blocking the air flow of cold from coming from the freezer to the fresh food section. This can be caused by a bad defrost timer, a bad defrost thermostat, a bad defrost heater, or a bad control board. It could be a week compressor that is only strong enough to cool the freezer, the evaporator fan may be bad, which blows the cold air from the freezer to the fresh food section, the damper control going from the freezer to the fresh food section, can be stuck in the closed position, or in rare cases, the light in the fresh food section can be staying on, or even the condenser fan that is responsible for keeping the compressor and condenser from getting to hot, may be bad. This is usually behind the bottom of the fridge. You might also have a dirty condenser, which is the coil that is usually underneath the fridge. So you are most likely going to have to call for service.

Ge monogram not cooling properly

It doesn't cool
  1. Condenser coils
Make sure you dust off the condenser coils to prevent dust build up and overheating due to it overworking. Simply unplug and use a long coil cleaning brush to get rid of debris.
  1. Check seals
If your refrigerator door seal is broken, warm air is pushing its way inside the unit, thus causing it to not cool properly. Prevent this from happening by replacing your seal and keeping the cool air inside.
  1. Temperature controls
Ensure that your thermostat is set correctly, usually 38-40 degrees Fahrenheit.
  1. Defective condenser fan
When this fan is defective, cold air is prevented from flowing through the vents. It may require replacement.
  1. Compressor issues
Check if there are clicking sounds coming from the compressor as it tries to start. If there is a clicking, it is one of only two options, either the start capacitor or a bad compressor. A start capacitor is fairly inexpensive whereas a sealed system repair on the compressor is very expensive and often not cost effective. Refrigerator Repair Help Troubleshooting and Parts

Fridge stopped cooling. light comes on but not cold. only 14 months old. we live where power supply can be iffy so power surges apply. is there a re set button anywhere on the frindge or compressor

Hi,Your start relay is bad for sure however the compressor could have caused the relay to go bad. The only problem is that there is no good way to tell if the compressor was the cause for the bad relay. The best way to tell is to replace the relay. I understand what you are saying, it would be bad to spend money on the relay then it turns out to be the compressor but there is just no definitive way to tell.

If you have a meter about the only thing you can do is to make sure the compressor winding are not grounded out. Check to see if there is any continuity from any of the three terminals on the compressor to ground and if so the compressor is bad. Even if the windings are not grounded out the compressor can still cause the relay problem. Be sure to unplug the refrigerator and the wires off the compressor before attempting to make this test.

I will say that 95% of the time (or more) it is just the relay.

The reason the fan wasn't running is because the compressor was off on the overload which cuts the fan off as well. The fan should have been coming on every so often when the compressor cooled enough for the overload to kick the compressor back on. If that wasn't happening the overload may be bad as well.

Overloads give very little trouble but when they are cutting on and off like they do when the relay is bad sometimes they will go bad as well.

Also, figure out if it's a short term or long term problem. If it's a short term problem, you've got it fixed. If it's a long term problem, then you'll need to take care of the food in your refrigerator while waiting for a repair person.
Can you Quickly fix a Refrigerator that's not Cooling?

start with the settings of the fridge. Often, the cause of a refrigerator not cooling is simply a misplaced switch - have the settings to cold, and see if the refrigerator quickly comes on. If it doesn't, be patient as on some models the cooling part of the fridge doesn't come on right away.
Is there Power to the Refrigerator not Cooling?

The quickest way of telling this is if the fridge light comes on. If it does, then there is power going to the refrigerator. If it does not, there's a chance that the light is just burnt out, however it's good to check in other places. Check the circuit breaker - sometimes a power surge can flip a breaker without you knowing, and be the cause of a refrigerator not cooling.

If the circuit breaker doesn't fix the problem, roll the fridge out and plug in something else to see if you can get power to same socket as the refrigerator.
First place to check - Fan in the refrigerator's freezer

The fan is often a part of the refrigerator that can break down - there are a number of moving parts, and this helps circulate the chilled air. Take a moment and see if the fan is running
Check the back of the refrigerator when it's not cooling

Is the back of the refrigerator warm? Most of the cooling function circulates through the rear of the refrigerator, and when it happens, the rear of the fridge warms up.
Refrigerator not Cooling? Call a Qualified Appliance Repair Technician

When your fridge isn't cooling, you should immediately call a qualified appliance repair technician. Look for recommendations from friends or family, and have one dispatched as quickly as possible. Keep in mind that most companies will take a few hours to dispatch a technician.

When waiting for help, keep in mind that the most important thing is to keep your food in good shape. Ask a neighbor to use their space, and consider eating or cooking anything that is perishable. Food can be very expensive, and once it thaws, in many cases cannot freeze again. Cooking food then refreezing it can add valuable time to your situation.

Compressor conning on for only approx 10 seconds and off for approx 30-60 seconds continuously. Freezer not cold enough to keep things frozen

Check condenser is cleaned. Replace relay and check compressor is working. If working keep your arm on condenser coil to feel warm. If not, no gas int he system. Call repairman to rectify. And also keep fridge temp setting between 36*F and 46*F and freezer temp between -14*F and 8*F. Thanks.

Hi.. feel the dividing rdge between fridge and freezer.. is it warm?.. chances are that the little fan at the back of the fridge freezer that helps cool the compressor, has snagged own it's own wire... it's a weak fan, like you get in a computer, but it does a lot of work.. without it, the coolent does not do it's job, which results in your device not cooling things properly

What kind of refrigerant does a 93 oldsmobile achieva need? Am I able to recharge it with R134a?

Why do people guess, this is what you need
93-92 Olds Achieva All Eng. ....... R-12 42.00 oz Mineral 8.00 oz
Vacumm the system to remove all moister and air (this is a must), I have converted many systems that were R12, with out change anything but the PORTS to allow R134 to charge the system and had no problems, always use high and low gauges, and a temp gauge inside the cars vents, this allows you to see what temp the air is coming out of the vents.
Add enough freon to bring the high side up to 150 psi, this will activate the cooling fan, check the inside temp. add a little at a time till the inside temp drops below 60 degrees, I have been able to get R134 down to 36 degrees, it depends on the systems condition. test drive and be cool.
Good luck

My refigerator and freezer are not cooling enough

You could call for service. It is commonly possible that there was a loss of gas, or the thermostat is defective, or the compressor is weak. The refridgeration service man should be able to check for all of this.
