Hey All... I just replaced the Relay Switch on the compressor. The compressor was kicking on every minute and just clicking off after 10 secs or so. My only concern is that I didn't use the Overload switch thatcame with my kit. If I hooked the new Overload switch up, the wiring would be different than the original. Three compressor prongs.. the original and current setup is as follows.. White > Top prong Relay > Bottom 2 prongs Red > Overload > Relay (connection #1 on relay) If I used the Overload switch, I would have to do the following. Overload > Top prong White > Overload (would have to be soldered on) Red > Relay (would have to solder again since Red is currently soldered onto both ends of the original Overload) So, should I do that? A bit confused... the Compressor has been running for a good 20 min now. I am not sure how to test the overload really. I do have a multi-meter and not scare to use it :) Here is the product that I purchased.. whirlpool 4387535 kit Refrigerator and Freezer Accessories Appliance Accessories - Find great deals, lowest prices, and buy whirlpool 4387535 kit Refrigerator and Freezer Accessories Appliance Accessories at Shopping.com Thanks for any suggestions in advanced

The compressor has been going for a good 1 1/2 hours now and it is extremly hot to the touch. I lowered the temp controls a bit and it went off by itself. The fan is going at a good rate. I also cleaned it all out. I didn't put the covers back on to help with the air flow though.
At any rate, I unplugged it since I have to go out for a few hours.

The most important is how the compressor will start, not run. All covers MUST be in place to provide the best airflow. That's why probably the compressor is hot on touch.
I can not verify if the part number you used for this relay/overload kit is correct because the model number you posted is incomplete.

Sorry about that...
I read in other places that the compressor should get warm at most. Also, that if it gets really hot it might be pulling too many amps.

This is correct if the cover is in place. Looking at the picture of the relay/overload kit  I do not see why you have to solder anything at all. I believe it's better to install both new parts from the kit. Gene. P.S. How does the compressor start now?

The compressor starts fine now. I am going to test it tonight to see how hot it gets with the cover on.
The red wire is currently soldered onto the old overload. So, I would have to remove that. It looks like that new overload is supposed to connected to the top prong. The top prong on the original and current setup is connected to the white cable. So, it just doesn't add up to me.

Compressor has been going for a good hour now.. Freezer got up to temp very fast, fridge is still getting there. There is warm air blowing from the bottom front (which is good).
I opened the cover and touched the compressor. It is still pretty hot, but not as hot. I can keep my hand on there for a good 5-7 seconds now.

Another quick update.. it appears this fridge is actually made around 1985! So, thinking a hot compressor is almost normal for a fridge that old. Meaning they didn't make them very efficient back then. I might just suck it up and buy a new fridge.

If it's really about 25 years old then your electric bill for this fridge is probably twice or even more higher compare to a new one.
