    Thanks Mr Mark 52 and Skeeter140..The little black box you refer to as the relay two pin connector, according to the schematic it is called the starter is that right? I shake it it does'nt rattle...After 30 seconds there is a clicking sound, according to the schematic it is called the motor protector with one pin connector...Both get warm to hot...Is there a motor inside the compressor? Someone said that the compressor will not work if the freon is low...The fridge is practically new, a shame to throw it away...2004 Sylvania se80102-3.....shade-ing

    Thanks Guys, I appreciate all your help...I will try to find a place to order this relay and hope that this will fix the problem.....To my understanding, when the switch does work the motor in the compressor will run? Looking forward in keeping the water bottles and most importantly the Beers cold!!!!!! I'll keep in touch of the outcome....shade-ing

There is a PTC relay on the compressor you need to replace it. Small black square looking device take the wire retainer clip off and pry off the relay. Get the wires going to relay noted and then get the model number and make of your unit. Go to a parts house for appliances and get a new one. About 25 bucks for that little dude but it is a needed for your compressor. Could get a 3 in 1 relay they are a lot cheaper and easy to install. let me know how it goes ken

Chances are, the compressor has locked up. You can try skeeter140's suggestion, but I doubt it will do any good.

Pull the relay off the compressor and shake it. If it rattles, then it's probably good. If it doesn't, go buy a new one as suggested.

Repair is not usually recommended.

    1) Yes, there is a motor inside the compressor.
    2) Yes, the relay inside the little black box is called a start relay, and it's either solid state (PTC) device, or it's mechanical. If it's solid state, just get another one as it's not easily tested. If it was mechanical, you should be able to see a heavy coil of copper or aluminum wire wrapped the outside of it. The rattle is a plunger/switch which makes up part of an electromagnet created by the coil.
    If the relay doesn't rattle, then the plunger is welded in the closed position, and that will cause the compressor to run about 30 seconds, then trip out on internal overload. When the overload cools, the compressor tries again, and the sequence starts all over again.
    And, so far, you've described nothing but an electrical problem. Don't go fishing into the freon side of the system because your looking down the wrong road if you go there. Unit's like this don't usually have low suction pressure switches on them (which would cause actions as you describe.). But, this unit's sounds too new for that to be the problem.


  • Mark Egan Jan 20, 2009

    Yes, the motor in the compressor will run.

    There are two windings in the motor, inside of the compressor. A start winding, and a run winding. Both windings are energized when the thermostat says "Make it cold in here.". But the start winding should only stay powered, through the start relay, for just a second or two, until the motor begins to run. Then the start relay drops the start winding out of the circuit.
    If the start relay does not drop the start winding out, the motor windings heat up, causing the internal high temperature reset to trip out (possibly after 30 seconds that you indicated.). Once it cools, the whole process starts over again.

I have a Samsung rs21!!! it wont cool in either compartment. when I plug it in the compressor fan does a quarter turn then stops. the compressor runs for about 30 seconds then cuts out? any ideas plea


most likely the start relay on the compressor that changes from start windings to run windings. the compressor will run for about 30 seconds on start windings then click out on internal thermal overload.
this can be confirmed by turning it on and letting it do the 30 second run then when it stops just wait and see if it cuts in and tries to run again (usually takes about 5 min) the second time it cuts in it wil most likely not run for as long (usually about 10 seconds). if this is what it does get a new compressor start/run relay.
as for the fan flick it with your finger and see if it spins freely.

Bar fridge not cooling


Sounds like you might be low on refrigerant (gas). Unless it is 134a, which you can buy in automotive stores, you are going to need a license to buy refrigerant. The simple way to see if you might need gas is by feeling the larger line going into the compressor (probably insulated). It should be cold if your system is working and charged. If you feel the line leaving your condenser, it should be fairly warm. Be careful as the line leaving the compressor can be very hot and burn you and you may have exposed electrical. If the lines do not feel cold and warm as they should you may be low on gas or you may just have a problem with your compressor or another part of the system. If you're not getting the warm-cold differential, it's likely worth just buying a new unit.

That is usually caused by the evaporator fan not running. It's located under the fridge accessed from the back behind the cardboard cover. The fan should run when the compressor runs.

Don't know the model/brand off the top of my head...

But: If the compressor is warm/hot, but nothing is happening, I ask this:
Even if the fridge is not cooling, is the compressor running, or dead silent?
If silent, but warm, do you hear a "Click" every so often ? Maybe 3 to 5 minutes apart, followed shortly by a 2nd click ?
If so, most likely the compressor has seized, and this is the over-current trip acting (thermal, so it needs time to cool).
Big problem if it is the compressor (expensive).

The only other thing that might cause a similar occurrence, would be if the compressor has a Start capacitor. If this has died, the compressor will not turn - just sit there getting warmer, as the over-current trip acts.

If it was a dead thermostat, the compressor wouldn't get power, and would be cold.

The fridge gets its cold air from the freezer through a vent(damper) between the freezer and fridge.The fan in the freezer blows air through it. There is a flap you adjust with the fridge temp. control. Make sure it's opening and closing when you adjust the fridge temp.

Fridge not cooling compressor works intermitently


If the compressor starts and runs for a few seconds it could be the relay. Or it could be the compressor itself has failed. When a compressor starts and runs for a short period it is possible that the relay contacts are arced together which would have both the start and run winding in the motor engaged at the same time for more than 3 seconds. This would result in the compressor tripping out on the thermal overload. It depends on what type of relay your compressor has. If it is a thermal relay, unplugging the refrigerator for about 15 minutes would allow the relay to cool off and reset.
