I replaced compressor for a hussman refrig and its hums loud

have a technician check it out but a frequency hum indicates a faulty start/run capacitor for the compressor
if you continue to let it hum ,it may damage the compressor

Check the rubber mounts under the compressor and look for any lines touching the sides of the cabinet. The gurgling and clunking are often normal. good luck. Roger

it has cooling problem.

Thanks for all the suggestions. I just replaced the overload relay and it does the same thing. Runs for a few seconds and the loud click from overload relay. I did notice the relay is really hot to the touch, if that matters.Coils on back are clean. I had noticed the last few months that the inside coils were frosting up quite a bit.Really had hoped it was the relay.

Hi, It is time to replace your compressor. Your compressor sucks the energy higher than normal. It has lower efficiency.
So I suggest to replace it soon.

Normally compressors fail due to overheating. But just like any machine that may run 24 housr a day 7 days a week, the compressor may just wear out. Overheating is caused primarily by stopped up condenser coils. The condenser coil is the radiator like object that sits close to the compressor and dissapates heat created by the compressor. Also if the fan behind the condenser coil fails because of an obstruction or fan motor burnout the heat will not be dissapated properly. The compressor has protection built in that should shut it off during an overheating situation, but it can't protect it over a period of time where the compressor keeps trying to start and shuts down due to overheating. If you look at the condenser coil in many cases you will find dust and or grease build up so dense that no air flows through the coil. This is simply neglect or not knowing that the coil needs to be cleaned periodically. Also, if you have a refrigerant (freon) leak, your compressor will overheat. The cold returning freon helps to keep the internal components of the compressor cool as well as keeping the oil inside the compressor churning up onto the internal components. If you have a leak, it is not sufficient to just add freon every once in a while. Leaks need to be fixed by finding the leak and welding the leak shut. No refrigeration system should require "gassing up" other than the initial charge of refrigerant. Overheating can also be caused by a lack of air flow through the condenser coils because there is no space around the machine for air to flow into and out of the compressor compartment. If you have recently replace a compressor and it goes bad again, it may be burnout residue from the previous compressor that clogs the lines after a burnout. I hope this answers your question.

Yes it is a very big concern.It sounds to me like your condenser is dirty and the compressor gets hot and goes off on overload.You can tell by putting your hand NEAR the compressor.Be careful as the compressor can be very hot

The humming noise is most likely from vibration, check to make sure the freezer is level.

If it is level look in the back lower area there is a compressor, black component about the size of a bowling ball, make sure nothing has fallen on it or touching it causing the noise.

change the rubber washers on the compressor should work a treat...

Sound's like the start relay overload on the compressor if you hear a humming and a click do not leave plugged in get new relay/overload at you local part store or the compressor winding will burn up and a new frig will occur message me if this is the sound and inconsistent cooling temp b4 you heard the buzzing and click take you model # to the parts store an easier repair which is good....
