Question about Kenmore 73502 / 73504 / 73509 Bottom Freezer Refrigerator

Refridgerator/B-Freezer not cooling

I've had the evaporator fan and relay switch to the compressor replaced in the last 18 months. Now the compressor is very hot and you can hear it humming to turn on, followed by a click and then nothing.

I'm guessing that the compressor has gone out, but is there anything I can do to confirm?

Also, I am fairly handy. Is changing out the compressor a difficult undertaking? Any special tools needed?

Thanks!

System refrigerant must be recovered prior to any work done on replacing any part of the sealed system, Recovery unit required at about $750.00. After recovery the compressor lines must be disconnected by heating to a temperature above 1385°F, Torch required , cost about $350. The compressor electrical wires must be disconnected. The motor mounts must be disconnected by removing clips or bolts. The compressor can then be removed. The new compressor can now be installed and the mounts connected. The piping can be cleaned fluxed and re-soldered using a high temperature alloy such as #45 silver solder. #15 if the stub tubes of the compressor are copper. A new system filter/dryer must be installed. Electrical wires must be connected to the new compressor. A deep vacuum must be pulled on the system to remove and air , moisture and non-condensible gases for the internal system. Then you can charge the system by weight to the exact amount shown on the system name plate and the proper tyep of refrigerant.

So the answer is yes it is difficult and requires a good technician to be done properly.

If the unit is out of warranty it is not recommended that the compressor be replaced at you expense.

How to test a defrost thermostat, to see if its working


Not sure exactly what the situation is I'm going to give you a detailed overview on how the system works that way you'll be able to isolate the problem. Your machine is a single compressor unit, meaning that even though there are two seperate sides, the freezer and the refridgerator, they do not operate independantly. The sealed system, which is what cools the machine, has two parts, a high side and a low side. The high side is located under the machine and consist of a condensor, for which freon is pressurized back into a liquid and passed throug the compresoor to be released as a gas into the evaperator, the low side. This is where the freon is at a cold state. Ok, now that you have the bare basics of a sealed system, we move forward. The Evaporator is located in the freezer side, behind the freezer wall. As freon goes through the evaporator, a fan, called the evaporator fan, is located above it and circulates air throughout the freezer compartment. Also, an airway connects the freezer to the refridgerator, usually top right of freezer, or top left refridgerator on side by sides and through the freezer floor on top mount models. This means the freezer cools the refridgerator side. ****First check point**** Is the fan running in the freezer? This would cause the freezer not to cool as well but also a rise in the refrigeration side would be noticed. As freon goes throught the evaporator, which is made of aluminum, the temperature levels are well below the freezing point, so frost and ice will form on the coils. Over time, this kind of build up would form a blockage, not letting air be drawn from the bottom of the coils by the fan to circulate the cold air. To prevent this from happening the a defrost heater is installed to thaw the ice away and comes on every 6-8 hours. This is initiated by the defrost timer, or in some machines an adaptive defrost control. The heater will be located at the bottom of the evaporator because hot air rises, getting maximum effect. A third part to the defrost system, the first two being the timer and heater, is a bi-metal,or terminating thermost. Its called this because when the thermostat is cold, the metal inside it constricts making a pathway for electricity to flow through to the defrost heaters so it can get hot, and as the heat rises and the ice melts away, the terminating thermostat will warm up, and the metal will expand causing the path of electricity to be broken, turing the heaters off. This is to prevent any high temperature situation from happening, like melting plastic or even a fire. If any of these parts fail, the machine will nit defrost. ***Checkpoint two***** Do you see any ice build up on the freezer wall. This ice will be completely across the back wall. Most signs of defrost problems are noticed first by a rise in temperature on the refrigerator side first. The above can be assessed with a quick look and listen. If no frost is present and the fan is running you can rule out the above. ****Please not that ice build up on just a small section, for example, upper left or right corner only is not a defrost situation but a sealed system issue, caused from low freon or a restriction in the lines and a EPA certified technician should be called.****** The last thing you should check you'll need to pull the machine away from the wall and remove the lower panel to gain access to the compressor area. What you are checking here is to see if the condensor fan motor is running and that the coils are somewhat clean enough for air to flow across them. The fan draws air from across the compressor and through the coils helping to keep the compressor temperature down and also to evaporate the water that is drain when the machine goes into defrost. Rule of thumb is if the compressor is on the fan should be. If the fan isn't runnning the heat from the compressor will be transferred to the machine and notice first on the freezer more so than the refrigerator. ****checkpoint three**** IS the condensor fan running? Are the coils clean, and can you feel the air from the fan with your hand placed on the opposite side of the coils?
The refrigerator side is usually where your defrost timer, discussed earlier is located. Also on this side is where your temperature control, or controls , are located, These controls are what are called thermostats, and have a direct line to the compressor. This means when the temperature has reached the desired setting the thermostat will kill power to the compressor in the same manner the terminating thermostat does with the defrost heater. Some models have a temperature control thermostat for the freezer and the refrigeratot, but some only for the refrigerator. The most noticeable sign of a thermostat being bad is the food in the refrigerator side will freeze, usually on any setting or the machine won't come on at all, including the fans. Problems are usually noticed on the refrigeratot side first. The last thing to discuss is The freezer and the refrigerator both are rising in temperature, but the fans are running, etc. Normally in cases like this a humming sound followed by click is heard or sometimes just the click. The humming sound is the compressor trying to start but failing and the click is the relay breaking contact. On newer machines, especially ones that fall under the whirlpool umbrella, the compressor relay, also called the start device has failed and needs to be replaced, but also the compressor itself could be bad. Well, thats the basics. I know it's long winded but I wanted to put something that you could print out and use as reference. Good luck.

REFRIGERATOR NOT GETTING COLD


. Cut everything off for a few minutes then turn it back on and listen for a click from the compressor relay as the compressor tries to start.
Is the compressor motor running.If no check starter/overload relay. If the relay is ok there is a compressor problem or low freon it it don't start

Check to see if the condenser fan at the back underneath near the compressor is running. If no check fan.

Are the condenser coils near there warm or room temp. should be warm




Is the evaporator fan in the freezer running. It blows cold air into the fridge side through a damper in the wall between the freezer and fridge. Make sure the damper is open.

Below the evaporator fan is the evaporator coils. Remove the back cover in the freezer to observe the frost pattern. Light frost everywhere(NORMAL) or a partial pattern of ice(LOW ON FREON) or nothing(LOW FREON OR COMPRESSOR PROBLEM).

It sounds like your evaporator fan motor, they last about 4-5 years. Try to see if the buzzing noise comes from the motor, usually in the freezer compartment behind a vented cover plate

The freezer is usually cooled by the compressor, the fridge is then cooled by an evaporator fan motor ($30). If this fan seizes or slows down then the fridge warms up (it sometimes starts squealing before this happens). It could be that your drain hose is clogged or frozen. Maybe the temperature adjuster go bumped.

If you think it is the evaporator fan motor:
Check to be sure you can get a replacement fan first, they last about 4 - 5 years. Can get from a parts supplier or electric motor company.
UNPLUG fridge. Located usually in top of freezer behind a vented cover plate. Remove cover, remove screws holding fan in, may have to cut wires. Replace with new motor, make sure the fan pushes air into the freezer area and doesn't spin backward drawing air from the freezer area.

Refridgerator not cooling


is it side by side or freezer on top/bottom...check to see if the fan inside the freezer is running when the compressor is running..also check to see if ice is covering the evaporator coils.. the freezing should be even with a thin layer of ice/ not partically melted..sometimes the ice forms in the vents and stops the air flow...to review...check and see if fan is working in freezer
check to see if vents are clogged......good luck!!

Kenmore Trio: the refridgerator is not getting cool


In the Freezer or Fridge compartment, there is the Evaporator Fan (& Motor) If the freezer is cold, the Evaporator fan motor most likely went bad. Check to see that when the compressor is running, so should be the fan motor. If not, you have to remove it & replace it. It is not an expensive repair unless you call for service on it. Make sure that you unplug the fridge when you replace the fan motor.

If the coils were really dirty, the compressor is probably just overheated. Let it cool down overnight then try again. If it still won't stay running it needs serviced. Could be the start relay or internal overload/overheat sensor in the compressor. If the coils were really dirty and it was used like this for a long time, the compressor could be damaged. It is almost never worth replacing a compressor in a home refrigerator.
