I followed the owner's guide in troubleshooting the problem I'm having with my frige. The evaporator fan ok,the condenser fan ok, I cleaned coil freeing from dust, I don't hear no sound coming from the compressor. please help

Possibly evaporator fan not working or defrost problem.

1-The condenser coils are usually located under the refrigerator. They dissipate heat as refrigerant passes through them. If the condenser coils are dirty, they won't dissipate the heat effectively. As debris builds up on the coils, the refrigerator becomes less efficient, causing the refrigerator to work harder to cool down. If the coils are significantly dirty, the refrigerator will not be able to maintain the proper temperature. Check the condenser coils to determine if they are dirty-if the condenser coils are dirty, clean them.
2-The evaporator fan motor draws air over the evaporator (cooling) coils and circulates it throughout the refrigerator and freezer compartments. Some refrigerators have more than one evaporator fan motor. On refrigerators with only one evaporator, the evaporator is located in the freezer compartment. If the evaporator fan is not working, it will not circulate the cold air to the refrigerator compartment. If this occurs, the freezer may still get cold, while the refrigerator will not get cold. To determine if the evaporator fan motor is defective, try turning the fan blade by hand. If the fan blade does not turn freely, replace the fan motor. Additionally, if the motor is unusually noisy, replace it. Finally, if the motor does not run at all, use a multimeter to test the motor windings for continuity. If the windings do not have continuity, replace the evaporator fan motor.

Sounds like a Freon leak. How old is the unit? You will have to decide if it's worth fixing or to replace. GOOD LUCK FRIEND.

Is the coil underneath clean, the compressor has a thermal overload the will cut off power if it gets to hot or the amp draw is to much. Just to clarify the fan in the unit is the evaporator fan, and the one out side is condenser. To clean the coil, use a vacuum first then use air to blow out the dust, water it better but you have to clean it up and if the shroud around the condenser fan is that cardboard do not get it wet, if its metal spray it clean. Hope this helps

Hi,

Many times a freezer and/or refrigeratordo not work right because of a dirty condenser coil...there are also many otherthings that can go wrong. If you are hearing a clicking or buzzing thencheck out the last two tips.

If your refrigerator is running but warm, then...

Check out these tips that I wrote about that... it is a great place to starttrouble shooting your unit...and something that you can do rather then callinga repair person to do a simple thing for you...

Hi and welcome to FixYa, I am Kelly.
Open the freezer and locate the door / light switch. Depress the light switch plunger / actuator and make sure the light goes off and the evaporator fan comes ON. Light stays on and fan does not run = bad door switch.
Next look for signs of ice build up on the back access panel / evaporator coils. Ice block noted on coils and back access panel = evaporator fan problem or possible door switch problem.
Last open the fiberboard cover on the back of the unit and check for massive amounts of lint on the condenser coils and that the condenser fan is running. Blocked condenser coils or condenser fan not running will cause the chassis to be very warm to hot when touched.

If you do not find anything wrong by performing the steps above:

• Unplug the unit
• Remove freezer contents
• Direct an external fan into the freezer compartment for just over 2 hours (manual defrost)
• Tend to the water mess as needed
• After 2 hours wipe up any residual water and return the unit to normal service
• Check to see that the evaporator fan is running.

After a 2- 4 days look again for any signs of ice build up on the evaporator coils. If you note ice beginning to build up on the evaporator coils there is a problem with the automatic defrost circuit.
Possible automatic defrost failure causes:
1. Defrost Control
2. Defrost heater
3. Thermistor (if so equipped)
4. Defrost thermostat

That is pretty much it runs all the time but does not cool troubleshooting. You should find something out of the ordinary by following the steps above.

Thanks for choosing FixYa,

Hi

There could be few reasons for your problem….
If your refrigerator is running too long or more than normal:
You may need to clean the condenser coils. This should be done about every 6 to 12 months. You can use a condenser cleaning brush, this comes in handy for cleaning hard to reach areas. Your refrigerator may be running too long, check the door gaskets for proper sealing, especially the bottom section. Clean the gasket surface where your door gaskets meets the metal with warm soapy water.
However there is a part of the condenser called the mullion loop that adds heat to keep moisture from building up and causing the door gaskets to stick. If it's too hot to the touch, first check your frige and freezer temps. You'll obviously know if the frige is too cold, but you may not know if the freezer is too cold. The freezer should be between 5-10 deg above zero. Any colder and the frige will have to work harder and would create more heat. Also check the condenser coils. If they are dirty it will prevent the frige from removing the heat properly. The condenser should be cleaned at least annually. Most friges have a condenser fan motor. Make sure the motor is running and the fan blades are clean. Most frdiges also have a cardboard type panel on the back at the bottom. That panel directs the air flow across the condenser and must be in place. If it's missing or damaged its need to be replaced.

Let us know if you have something more to ask else please accept the solution.

If the condensor fan is running, then your compressor should be. If not.. you'll need the relay- overload- capacitor replaced...unless the compressor itself is bad.

It is possible you have a defective fan motor in the condenser area or evaporator area. Sometimes when they become defective they will run for a while and just warm up and stop while the compressor continues to run. I learned that one on four costly returns to the home. The cost was to me not the customer. Thanks, Sea Breeze

Poor cooling is often the result of a heavy frost build-up on the evaporator coils or a condenser that is clogged with dust, lint, and dirt.

Evaporator coils Poor cooling is often the result of a heavy frost build-up on the evaporator coils. You can't see these coils without removing a panel on the inside of your freezer. A sure sign that there is a build-up is the presence of any frost or ice build-up on the inside walls, floor, or ceiling of the freezer. Such a frost build-up usually indicates a problem in the self-defrosting system or damaged door gaskets.

The refrigerator is supposed to self-defrost approximately four times in every 24 hour period. If one of the components in the self-defrosting system fails, the refrigerator continues to try to cool. Eventually, though, so much frost builds up on the evaporator coils that the circulating fan can't draw air over the coils. There may still be a small amount of cooling because the coils are icy, but with no air flow over the coils, cooling in the refrigerator compartment is quite limited.

Here's an inexpensive, though inconvenient, way to determine if the problem is with the self-defrosting system. Remove all of the perishable food from the refrigerator and freezer, turn the thermostat in the refrigerator to Off, and leave the doors open for 24 to 48 hours. (Be sure to have several towels ready in case the melting frost and ice causes the drip pan to overflow). This allows the refrigerator to defrost "manually." When the frost and ice build-up has completely melted away, turn the thermostat back to a normal setting. If the refrigerator then cools properly, it indicates a problem with one of three components in the self-defrosting system:

• The defrost timer



• The defrost thermostat (also called the bi-metal switch)



• The defrost heater

If it still does not cool properly, there may be a problem with the refrigerant level or the compressor. You may need to consult with a qualified appliance repair technician to further diagnose the problem

Condenser Self-defrosting refrigerators all have a set of coils and a cooling fan, usually under the refrigerator, that need to be cleaned regularly. If these coils get coated with dust, dirt or lint, the refrigerator may not cool properly. The coils may appear to be a thin, black, wide radiator-like device behind the lower kick-panel. To clean them, disconnect the refrigerator from the power source, use a refrigerator condenser brush (see the Appliance Accessories section) and your vacuum cleaner to clean the coils of any lint, pet hair, etc. You may not be able to get to all of the condenser from the front, it may be necessary to clean the remainder of the condenser from the rear of the refrigerator.
