Question about Refrigerators
There are several reasons for a compressor to run too hot, including high compression ratio, high return gas temperatures, and lack of external cooling.High compression ratios are the result of either lower than normal suction pressures or higher than normal discharge pressures. Changes in suction pressure will affect the compression ratio more rapidly than changes in the discharge pressure. For this reason, it is important to keep the suction pressure at its highest possible value.
Causes of low suction pressure can include incorrect sizing of components, misadjusted or defective metering devices (TXVs), loss of refrigerant charge, plugged driers or strainers, and excessive suction line pressure drop.
Although not as sensitive to change as the suction pressure, the discharge pressure can still greatly affect the compression ratio. Keeping the discharge pressure within normal operating conditions is still important.
Causes of high discharge pressure can include dirty condensing coils, undersized discharge line, a blockage or recirculation of condenser air, erratic condenser fan operation, refrigerant overcharge, noncondensibles in the system, and an undersized condenser.
Many larger refrigeration systems with electronic controllers will automatically monitor the temperature of the discharge line and will send out an alarm to alert the owner or service contractor of a potential problem. Regardless of how the discharge line temperature is monitored, it should always be checked as part of any service to a refrigeration system.
A technician should also check the discharge line temperature within 6 inches from the outlet of the compressor. Any temperature above 225 degrees should be investigated and the cause found and repaired.

Mine leaks. Had leaked at other times but i took the vacuum cleaner to the front drain spout, that leaks into the removable basin. That worked in the past, but i't's not working now . The water is overflowing at the back of the catch tray and leaking out through the bottom underneath. The holes are clear, so it shouldn't be doing this. I am stumped.

Welcome to fixya.
I'm Huuum and happy to assist you,
I believe your problem is an old compressor about to go!
At 11 years old My advice is do not put good money into bad!
A new fridge will pay for itself in a few years by using a lot less electricity!
Here is an interesting report I just read!
Repair or replace?
When to pull the plug on your old refrigerator
It nearly always makes sense to undertake simple do-it-yourself repairs,
such as replacing a gasket on a refrigerator or a freezer.
Typically, you'll also find a troubleshooting section for more-serious problems
in the owner's manual.
Should you pay for a repair or buy a new model?
The answer depends mostly on the age of your refrigerator,
how much you bought it for,and the cost of the repair.
Follow these guidelines:
When a repair makes sense.
If your refrigerator is under warranty or less than four years old (three years for top-freezers),
paying for a repair makes sense.
Note that refrigerators under warranty might require service from a factory-authorized technician;
readers have found them on a par with independent repairers.
When a repair might be a wise choice.
If your refrigerator is out of warranty and is four to seven years old,
it might make sense to pay for a repair. Customers generally pay $100 to $200 for a repair.
But you might want to buy a new model even at this stage,
given that today's models are quieter and have added features.
Higher energy efficiency is another plus: Energy Star-qualified models made after April 28, 2008,
are 43 percent more efficient than conventional models built before 2001 and 56 percent
more efficient than those built before 1993.
When it pays to replace.
The repair costs more than half the price of a comparable new refrigerator.
Data also shows that it doesn't pay to fix a less-expensive top-freezer refrigerator
six or more years old or a bottom-freezer or side-by-side eight or more years old.
Thanks to better recycling programs, less than 10 percent
of a refrigerator you replace is likely to end up in a landfill.
Thanks for giving me the opportunity to help!

Thank You, HUUUM

you may just have a bad relay. with the power removed ..(unpluged)
remove the relay cover ( on the side of the compressor)
remove overload and relay
check relay for 4-5 ohms
check overload (if open it is bad)
let me know

U-line does make compressors as long as its not a r12 system. As far as the icemachine turn breaker off for a couple of min then try it. If same results then it could be a board.
