Ok. By the way...you have a fan motor near the compressor. When you plug the unit back, observe this fan if it is running,. It should be running the same time the compressor runs. If this fan is not running, then that could be the cause why the compressor is over heating.
If I am offline, just post what you find out and I will respond as soon as I log back in after about 6 hours...thanks.
ok. Did you take a look at the fan? is it running? The cover should be placed back while testing the unit. This would ensure that the condenser coil will be cooled down.
Here is a parts diagram that would look like your unit. Please click the blue words.
Please take a look at the front of the unit. Remove the front kick panel and check the condenser coil if it is clogged with dirt and dust. That would be item 15 on the parts diagram.
If it is dirty, give it a good vacuum and cleaning. Then do the test again after 4 hours of not running. Make sure the cover at the back is in place so that the air would pass through the condenser coil from the front.
ok. i will be waiting....
OK. Please tell me if the fan near the compressor is running when you started it, and you put the back panel back in place.
IS the clicking sound still there? Is the buzzing sound different from the clicking sound before?
If it is the same, try to replace the capacitor as well as the starting relay if you just replace the overload relay. In this parts diagram, the capacitor is item 8 and the starting relay is item 4.
One more thing, when the buzzing starts, does the unit stops cooling? ( If there is the clicking sound, the unit would stop cooling but if there is no clicking sound and it is just a buzzing sound, then the unit might continue to cool down)
