Motor/compressor hums but does not run. is there a reset button on this unit?

I would check to see if the compressor is running(humming or making a continuous noise). The compressor is in the back of the freezer and approximately the size of a football.

If is not running but you do have power, there may be a problem with one or more of these:
The compressor
The Thermostat
The overload, relay, or capacitor
The defrost timer
The condenser fan motor

You might need to call a repairman.



You might

motor humming is from 2 things
start / run capacitor is failed
compressor is seized and the motor is not turning
call in an technician for a proper diagnosis and quote

Most likely t-stat. If the t-stat is good then move to compressor. If you hear a hum then a click and it shuts off, that is the internal overload telling you the compressor is done and needs to be replaced.

GIVE IT TIME SO THE THE SYSTEM COULD STABILIZE IT SYSTEM FOR A FRESH STARTUP. OR HAVE CHECK TO ITS OVERLOAD UNIT THE COMPRESSOR MOTOR.

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

God day,
Either the refrigerant has leaked out or the compressor isn't pumping properly. If you can put your ear up to the unit and it hums that is the compressor running.
No practical repair possible unless the unit is under 5 years of age in which case you are entitled to factory warranty service.

If the fans your talking about are in the refrigeration section, then the unit is not in defrost. The interior fans shut off during the defrost cycle.
There is a condenser fan motor in the machine section by the compressor. If it fails, the problem you described can occur.
If that fan motor is still, and the compressor is cool to the touch, then no power is getting to the refrigeration section.
Could be a bad thermostat, or the unit has tripped off on the high pressure safety switch. The high pressure switch can be one of 2 styles. Auto reset, which means it will try to restart the compressor when the pressures become normal. The other has a lock out feature that requires it be reset manually. If it goes out on the high pressure switch, once reset, check the condenser fan motor to make sure it is running and/or excessive dirt in the condenser, which must be blown out.
Other causes can be a total loss of refrigerant, or a compressor that won't run.
Short of a broken wire all items listed except for a dirty condensor and reset of the high pressure switch, require a decent knowledge of electrical, Knowledge in the use of a VOM meter and amp-probe, as well as a set of refrigeration gauges.

Is the thermostat knob turned to the proper setting?

Is the compressor motor running? It's a football-sized case with no apparent moving parts on the outside of the freezer at the back near the bottom. Is it humming or making any kind of continuous noise? If it is, but your freezer is still not cooling at all, there may be a serious problem with one or more of these areas:

• The compressor
  
  
• The condenser
  
  
• The evaporator
  
  

You can't service these yourself. You need to contact a qualified appliance repair technician.

If the compressor isn't running but you do have power to the freezer, there may be a problem in one or more of these areas:

• The compressor
  
  
• The overload and relay
  
  
• The defrost timer

A hum followed by a click sound is an indication of a failure at the compressor. Possibly the compressor motor has gone into a locked rotor condition. A locked rotor condition can be checked using an ammeter. The name plate on the compressor will have a rating after LRA. If the ammeter reading is equal to the LRA rating the compressor is done. If it is a reading of about 80% of the LRA (locked rotor amperage) it is possible that a relay or capacitor has failed which is replaceable.

There is no reset switch. There is a thermal overload protector mounted on the compressor. Does the compressor hum and then give a click sound. If so your compressor has failed. If the compressor is cold (Room Temperature) and it does not try to run your thermostat may be bad. If so remove the temperature control and jumper the two main wires that connect to the control. Unit should be unplugged to do this operation. Insulated the wires so they do not contact any metal surface. Plug the freezer back in. If it runs and cools replace the thermostat.
