Question about Danby DWC440 Wine Cooler

Open Question

Adding Freon to the Wine Cooler

Seems like we have the same problem as other folks. Freon must have leaked out. 1) Can freon be recharged at home? 2) Exactly how can it be done? 3) What freon do we use? Thank you - M

    We're having a party and just noticed the cooler wasn't working (temp inside 75ยบ )
    The previous question about adding freon - does not appear to be answered? What can be done?

SOURCE: need freon recharge. punctures freezer coil in

You punctured the aluminum evaporator . In the many years I've been in refrigeration , I have yet to find any way to patch a hole in the evaporator . I've used epoxy , solder , and all different advertised ways to try to patch aluminum . Nothing worked ( for long anyway ) . My suggestion would be to buy another refrig . You will be wasting time and money trying to " fix " this problem . To repair it yourself , you have to have a license to buy R12 , maybe you can buy R134A without a license , you have to look on the " modell , serial number tak to see which it uses and how much to use . Also , the system has to evacuated ( all air removed from the lines ) . Do you have a vacuum pump ? You have to buy a solder on connector ( or saddle valve which WILL leak eventually unless you get a solder on valve ) which will connect to the larger tubing on the compressor or use the access line already on the compressor but is pinched off . Do you have guages for the refrigerant type you need to use ? Once you have these things , reply back and myself or someone else will help you procede .

SOURCE: leaking water from the back

make sure that the drain is connected properly at the back.

Make sure that the little drain pipe (usually clear hose) is sitting in the plastic shroud that sits on top of the compressor at the back of the fridge.

SOURCE: Danby Silhouette Wine cooler won't

Hi sooner84,
I really like the Danby wine coolers, they are usually nice products. As far as your problem, I would first try to find out where the main problem area is. To do that first make sure that your compressor is running. If the compressor is running and it is not cooling then you may have a freon charge issue. Thats not to say that you can just put some more freon in and it is fixed, You would have a leak in your sealed system and you would most likely still have warranty coverage for that. Most Danby products carry a 5 year sealed system warranty. That would include your compressor.
If the compressor is not running then you would know that you have a compressor issue. Either the relay overload on the compressor would need to be replaced or the compressor itself was bad. You can buy relay kits for about $30.00 and intall them easily with very little experiance.
Next if the compressor is doing its thing and trying to cool you could have a fan not blowing air properly. either a condenser or evaporator fan may have stopped. If you find one not working then chances are you just need a fan. If the fans are blowing and the compressor is working then you would just have a defrost problem. In that case you would just need to defrost then check for bad parts, either a defrost heater, defrost thermostat or a defrost timer. Most of the Danby products have a defrost control board, that board willl contorl the defrost, the temperature, and the fans. If the board was cheap I would say just put one on and see if it fixed the problem, but they are around $145.00.
The most important thing for you would be to make sure you are not going to do something that would void your warranty. Free service is always the best. Good luck to you and send some wine my way, I make lots of different types. from grapes, strawberrys, muskedyne, etc.... mca0824@aol.com

Undefind Freon leak


that is a very fast leak. try using UV dye leak detector. color of this dye is bright green and will be show at the leak source. a UV light is also helpful so you can see it better. you can buy this at any auto parts with freon mixed with it, with this leak you should see oily trace at the leak area, don't forget to recharge compressor oil after your repair.

Freon Recharge


FREON SHOULD NOT ESCAPE AT FIRST! IT CALLED SEALED SYSTEM, SO WHEN YOU RECHARGE FREON, PROBLEM OF LEAK IS NOT SOLVED, IT WILL WORK FOR A WHILE, BUT FREON WILL LEAK OUT. REPLACE FRESH FOOD SECTION EVAPORATOR - THE MOST COMMON FIX FOR THIS "SERVICE" OR "VACUUM CONDENSER" LIGHTS. CHECK ON THE VIDEO.

I put freeon in my 2001 hyundai sante fe and its still blowing out warm air


If you put freon and the system still seems to be leaking then this means you have a leak in the system. Head to your nearest auto repair shop and have them do an a/c check. They will use a special dye that will pin point exactly where the leak is coming from. After you fix the leak, the repair shop can offer you an a/c revac and recharge to fill you whole system with freon after the leak is repaired.

Hope This Helps!

When at a stop light my 2001 gmc 2500hd A/C starts blowing warm


Your freon level is low and needs to be recharged. To have this done properly, a total evacuation of the A/C system should occur so that the seals can be replaced. The seals are leaking and that is where your freon is going. Once the seals are replaced, the system is then recharged with the proper amount of freon. Hope this helps.

1992 ford aerostar ac not working


Below is a guide to troubleshoot and check system function. This can be done by most folks.

Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.

If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.

The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.

The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.

The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.

The system should be filled until suction pressure is about 30 to 38 psi..

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP2_bing.gif liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer back to the compressor suction.

How can i recharge the air conditioner? Where is the hose located?


Ok if you want to do a home repair in hopes of saving yourself a lot of money and with hopes your system is not in major trouble, here goes:
First step buy 3 types of 1 lb. cans of refrigerant R134a at a parts store, 1 can of leak detector freon combination, and if possible 1 can freon/air conditioning oil combination freon along with 1 can of straight r134a freon.
The store will sell you a charge hose with a cheap type of charge gauge attachment and fittings to attach to your system for the re-charge.
Providing your system is low on freon,First, with the vehicle running and the a/c on full cold, high fan, install the 1 lb. can of freon/oil combo first only charging through the low pressure side of the system never through the thin line high pressure side as the pressure from the high side can enter the cgharging freon can and explode it like a bomb,(this low side line is the larger hose and the low side charging hose fitting the parts store sells you will only screw onto the low side charge valve which is normally marked "low" on the top of the plastic dust cap that is factory installed(hand screwed) on the low side valve fitting.
Secondly after the oil/combo can is emptied into the low side and you of course are wearing mechanics hand protection gloves and eye protection googles, then and only then will you install the leak dector 1 lb. freon can combo.
Third you will install the last 1 lb can of r134a freon, however your vehicle will not allow the whole last pound of freon into its system by means of a pressure relief blow valve that will automatically blow off any excess pressure once the system over fills, the system typically holds approximately 2.75 lbs. of freon.
If you have successfully installed the above freon into the system it should be up and running providing the system is in fairly good working order, by that I mean it may have a very slow leak that allowed the freon tio originally escape in the first place causing you to refill it, and if it does have a leak the leak detector die that you installed into the system should leak out from wherever it may be escaping from, indicating the place of needed repair by means of a red or blue, or whatever other designated coloration the die gives out from the leaking area.
Please note: Not all home charging techniques typically work as there are many mechanical failure factors in an a/c system that may require a certified a/c technician to determine exactly why your system is not working should the home remedy fail.
I hope this helps you and remember to always work safe with eye and hand protection especially around freon gases which become extremely cold and can cause frost bite when contacting with the bare skin.

Cooling system


All the parts that you mentioned are the correct parts that you need to check if there's a problem with the cooling system in your jeep. It's just that you missed to check two (2) things:

1. Freon
2. Leak

If there's a leak in the copper tube, your car will run out of freon. If the freon is low, then the jeep will not get cool.

Contact an A/C tech to check if there's a leak, fix it and recharge your jeep with freon.

Have a great day!
