    Digital reading stays at 39 degrees so cooler compressor doesnt kick on. Have adjusted thermosta to no avail. Even have unplugged unit overnite and the setting stays within a couple of degrees of 39F.Consequently the compressor doesnt run long enough to cool items. Sometime digital number radomly go as low as lower 20's as if thermosta no working properly. Dont nknow where thermosta is located plug do not have tools or eqpt ot check if properly functioning..Please help

Hi and thanks for coming to FixYa.

I would check your thermostat. The thermostat checks to make sure how cold the unit is and when it reaches the desired temperature, it kills the power to the compressor.
It is located directly behind the temperature selector. If you don't have the tools to check it and/or not sure how, then just replace it. It's easy to and doesn't cost much money.
Make sure you unplug the refrigerator. Take the temperature control off, it should just take common philips screwdriver. Get to it and remove the power leads. (Write down the color combination so you don't forget.) Got to an appliance repair shop and show it to them. It should have the numbers on it so you get the same one. If not, they can look it up at the shop. Then take it home and replace. Don't worry, it's easier than you think. Let me know how it goes!

As you stated compressor does not  kick on check out this Compressor won't run or it is "clicking' on and off: This normally could be a bad start relay and over load for the compressor, dirty condenser coils need cleaning, condenser fan motor is not running or the compressor itself. To check the compressor properly you should test it with an amp meter, each compressor is rated in running amps  ( see model/serial tag or the sticker on the compressor )...if the compressor is drawing too much current, this may be why it is shutting off. Check the model tag for proper amp rating. Some relays will be easy to notice the broken with them, they may be burnt. Example oneexample twoexample three. Some of these relays can be removed and give them a little shake, and if they rattle around inside the relay is likely bad. Compressors can also seize and click on and off or one of the electrical windings inside the compressor could have opened up. You can use a test cord to help check the compressor and this also will help with the amp test. If the compressor checks ok and you want to install areplacement start relay. You will need to find out which winding is which. You will need an ohm meter to determine the windings. First check to see if you have windings in the compressor. Then check to see if they are grounded. If the compressor has windings and they are not grounded, you can find which winding is which. Check for grounded windings by reading from each terminal to a good ground on the cabinet. Read from the top terminal to the lower left terminal. Read from the top terminal to the lower right terminal. Read from the lower left terminal to the lower right terminal. Write down the resistance of each reading as you go. The highest reading you get will be the run and start winding of the compressor in series with each other. The other terminal left will be the common terminal. Read from the common terminal to each of the other terminals. The terminal with the lower resistance will be the run winding. The higher resistance the start winding. Using the original style relay is always preferred, but using a general replacement can "get you by" if needed.
A few things to check for is - power at the outlet, check for 120 volts. If the light inside the fridge works, the defrost timer,cold control and possibly the wiring are the most common things that can make a fridge sit there and be "dead", not running. The defrost timer might be stuck in defrost, turn the timer screw to advance the timer and if the fridge comes back on, replace the defrost timer. You can join the wires together to by-pass the cold control for a test, if the fridge comes on, replace the cold control.

The thermostat cycles the refrigerator on and off. The refrigerator normally runs as long as the temperature inside the refrigerator is higher than the set temperature. If the temperature inside the refrigerator is cold enough and the thermostat still does not cycle off, the thermostat may be defective. If so, you need to replace it, because it cannot be repaired. If the thermostat is not defective, you may have a problem with the sealed (refrigerant) system,.
and you will have to replace the thermostat.its faulty.

The temperature sensor is possibly faulty, have you considered replacing the sensor to see if that solves the problem?

How the warranty? is it out?

Posted on Mar 02, 2009

  • Ekse Mar 02, 2009

    That was my mistake, the temperature sensor is not related to this at all. Suggest to follow ginkos advice in this case. Thank you, please repost over my solution.

Cooler Compressor runs but cooler won't get cold?


If the compressor kicks in then check the lines to see if they are cold. It is possible the compressor burnt out from leaving the door open. Purchase a sensor alarm to alert you if the door is left open.

Vinotemp not staying cool, it's set at 54 degrees, but it's at 82 degrees


Step 1:

It's most likely the PTC (Positive Temperature Compensated) start relay that turns the compressor on and off. The manufacturer has replaced part number P6R8MC with part number 6R8MG for this PTC start relay. Order part number 6R8MG, it cost less than $20.

First, unplug the wine cooler and take off the back panel. The back panel is held into place with several philips head screws.


Step 2:

Locate the compressor. You'll find the compressor in the bottom left corner of the VT-60 as viewed from the back. You will see copper tubes coming out of the compressor. These tubes carry the compressed refrigerant to the evaporator assembly. Be careful not to crimp or damage the copper tubing.

Step 3:

Find the black plastic cover to the left of the compressor. This cover is held into place with one philips head screw. Remove the screw and remove the cover to find the PTC start relay.

Step 4:

The replay is connected to the compressor by a single blade connector and two pins which protrude from the compressor. Remove the blade connector and pull the PTC relay to the left, sliding it off the pins attached to the compressor.

Step 5:

Slide the relay on the connector pins, reattach the blade connector, reattach the black pastic cover over the relay, reattach the back panel onto the VT-60 and you're done.

Unit will not stay cool. Is it a thermostat, compressor?


Small refrigeration units like this one like to fail to cool by developing a small leak and slowly
leaking refrigerant.
THERMOSTAT FAILURE CHECK:
A technician will check the thermostat using using a DMM (digital multimeter). But you can suspect the thermostat if you set the thermostat high and the compressor motor does not run,
then set thermostat low, and the compressor motor also doesn't run - in other words, the thermostat is failing to start the refrigerator's refrigeration system no matter what its setting - an obvious failure of the thermostat.
COMPRESSOR FAILURE CHECK:
If the compressor is dying, you would hear the compressor running almost constantly, but not
sounding quite right (uneven noise, clunking, tapping).
REFRIGERANT LEAK CHECK:
If you unit is low on refrigerant (due to a leak), the compressor motor will be running
almost constantly, but it will sound Ok.

Wine cooler just stopped working. light will come


Try disconnecting all power to the unit for about 10 mins, and turn it back on to see if the compressor will kick in. Also check your temp settings and make sure they are properly set. If that doesnt work, you might have a dead compressor which a tech can look at and verify.

If the unit is a thermoelectric unit it can be the cooling system.
If the unit is a compressor unit it will be the thermostat.

Whirlpool Beverage Center (WBC127BLS) - Won't cool enough


If you're handy with a soldering iron, it's possible to 'trick' the fridge into cooling down a few more degrees.

Long version:
If you open the door to the fridge, on the right wall near the bottom is a small plastic grate. You should be able to pull this straight out from the side wall. There is a temperature sensor attached to the back of the grate. Unplug the sensor. (The fridge will then give you a very annoying error beep and display "EE" on the readout. Pushing the °F-°C button stopped the beeping.) This sensor will change resistance with temperature. (The lower the temperature, the higher the resistance) I was reading a resistance of about 3700 ohms at 43°F and 2460 ohms at 68°F. Throw in a rough assumption that the response is linear and it works out to almost 50ohms/degree. In order to 'trick' the fridge into cooling down more, you need to drop the resistance. I was aiming for about 6 degrees cooler. Assuming the resistance response was linear, 6 degrees cooler would give me about 4000 ohms from the sensor. By jumpering a 50000 ohm resistor (yes, 50K ohm) in parallel with the sensor, I should get about 6 degrees cooler. I did the soldering, plugged the sensor back in, and ended up about 8 degrees cooler. Two days so far, everything appears good and the beer is cold.

Short version:
Put a 50K ohm resistor in parallel with the temperature sensor behind the grate on the inside right hand wall.

The temperature read out will be inaccurate forever after though. But then, I just want cold beer, my wife wants cold water, and the kids want to play with the cool blue light. I don't care what the number on the readout is.

True Refrigeration GDM-26 Compressor problem?


More than likely you need a new compressor. It sounds like it's trying to start and then trips on it's "Klixon" overload. Call a commercial refer guy (not somebodys brother in law that works on A/C, it's NOT the same!)
