Should the compressor be hot?
Yes, when a compressor is operating it will run hot to the touch. If it is cool or just warm then the compressor has not been operational or it is not pumping refrigerant.
Hello, I have a Kenmore Model 253.62244201. I was told by a representative of APP that the fridge is made by Fridgidaire, and the part number of the compressor is AP4499996.
We purchased the fridge new in 2002, though about 2 years ago, we hired Sears because we suspected that the fridge was using too much electricity, based on a meter we were using for that purpose. It turns out that the fridge was consuming a normal amount of energy, but our meter was defective. In any case, the technician replaced the compressor as part of the process, so we have a compressor that is only about 2 years old.
The fridge is not cooling properly. Conditions vary over time. Sometimes it is cooling, other times not at all. Freezer is defrosting and items within are thawing. Compressor is hot to the touch. Doesn't burn my skin, but is uncomfortable.
I have run into several threads indicating there is a simple test with a multimeter that can be used to test the windings of the compressor. With the power unplugged, I have removed the plug on the side of the compressor, and three pins are visible as a result, in a triangular pattern, a single pin on top and two pins below it, side by side.
How do I use a multimeter to test the compressor? What are the values of resistance that I should get and from which terminals?
The top pin is the common and the other 2 are the run and start. You would first check from common to each of the other pins. The readings should be around 5 to 9 ohms. Then check across the 2 lower pins and the reading that you get across these should total about the same amount that both of the other 2 readings added together. It should be roughly 11 to 13 ohms. You will also want to check the condenser fan to make sure that it is operational as a non working fan will cause compressor to overheat. Also check the start relay to make sure that it is good. You do this by shaking the relay to see if it rattles and if it does then it is bad. Also when the unit stops cooling double check to make sure that the fan are running. If the fans are not running then the unit may be sticking in defrost.
My freezer currently has an RF107-1 compressor. The compressor kit that is recommended for replacement contains an oil cooler. My freezer does not currently seem to have an oil cooler. What is recomended that I do with the oil cooler? Leave it off? Mount it where? Thanks.
Answer Hello Bill,
If the compressor that is recommended goes onto a unit without an oil cooler and the compressor has an oil cooler, leave the rubber caps on the cooler lines and install the part into the unit. I have done this many times and it never has caused a problem.
You state that the compressor kit doesn't ship charged with freon. Where and how would I get it charged with Freon?
Answer Hello Mark,
The sealed system has to be recovered and charged by a freon certified technician as per federal law.
There is a wining sound coming from the compressor in short intervals. It also stops making ice. Then after a few hours it starts making ice and cools the refrigerator section. Please help
Answer Hello Gene. Based on the information you provided, it sounds like the compressor 5304475140 is bad and will need to be replaced. You can test the compressor.

My compressor was changed out 5 years ago. Now, it is making an unusual loud noice when operating. Do you think the compressor is about to go out again and I should change it now?
Answer Hello Tina. If the noise is coming from the compressor, then the windings may be going bad. If so, you will need to replace the compressor before it goes out. Hope this helps.
