RPLACE DANBY FANS HOW?

If your Danby DBC514BLS-1 beverage fridge is not cooling and you have noticed frost on the back coil, it could be a sign of a problem with the fridge's defrost system. Here are some steps you can try to troubleshoot the issue:

1. Check the fan to see if it is running. If the fan is not running, it may be a problem with the fan motor or the control board.
2. Check the defrost timer and thermostat. The defrost timer controls the defrost cycle, and the thermostat monitors the temperature inside the fridge. If either of these components is faulty, it could cause the fridge to frost up.
3. Check the wiring and connections. Make sure all the wires are securely connected and that there are no loose or frayed wires.

it is possible to replace the fan in your model of fridge, If you decide to attempt the repair yourself, you will need to purchase the correct replacement fan for your fridge and have the necessary tools to make the repair.

For those refrigeration systems that employ a fan it is usually positioned to push cool ambient air through the condenser, being somewhat more efficient than pulling air through it because unless it is fitted with a close fitting mask or cowl the fan could pull a great deal of air from the sides completely bypassing the evaporator...

Guessing here, Bad thermostat would affect both sides, not just half. I would look for a door or damper door, an obstruction in the air path between the two, where the inside fan lives and on down to the other side if defrosting does not show any difference after plugging it back in a day or two later. If it shows a difference, then there is a defrost problem, deftost cycle not working.

There are 3 fans in this unit. One high up in the back panel for defrost (which should seldom run), and two inside the box with the LED's that divide the compartment into upper and lower areas. All are interchangeable. Replacement parts are available through Sears Parts Direct.
If you intend to do the repairs yourself, make sure the cooler is unplugged when working on it. To gain access to the two fans in the divider box, remove the wine racks to give you more room, and just remove the four screws holding the top of the divider box on and lift it off. One of the fans is directly behind the PC board and the other is inside the 8x10 foam box to the rear of it. Be careful with this foam box, it is delicate. To gain access to the fan inside, use a thin bladed knife or razor blade to delicately separate the top from the sides.
Before replacing fans, try tracing the leads from the fans to the PC board and swapping the plugs for the fans on the PC board and plugging the cooler back in to see if any of the fans are working. Make sure you restore the plugs to their original positions. If all three fans are not working, the problem may be the PC board or the thermocouples.

The problem with the factory fan is that it is a sleeve-bearing fan. On average, a fan should operate for about 50,000 hours, which if it runs continuously would be over five years. However when the operating temperature rises or the fan is installed "not exactly" vertically, it will have shorter life.
I had to replace my fan two times withing two years since we bought the unit! Plus the stock fan becomes quite noisy after a couple of months of work.
With all of these problems I did some research for better fans and decided to purchase a ball-bearing fan to install it into the cooler by myself.
Ball-bearing fans on average outlast sleeve-bearing fans by 50 percent and produce less noise.
It's very important to purchase the right AC 115 Volts fan for this Danby wine cooler.
The original fan is Rullian Science RAL 1225S2 (120x120x25 mm in size, 100-125V AC, 0.09A)
The replacement model is Orion OA12AP-11-3TB which I got for $16.75 from Mouser Electronics (mouser.com). The replacement model is ball-bearing cooling fan with slightly higher/better parameters, which will help to cool down the wine cooler coil faster.
To replace the fan you need to tilt the wine cooler on the side and unscrew two small screws at the bottom that keep the original fan in place, remove one screw to the black box where the fan wires are attached and unplug these wires. Then you just need to replace it with the new fan and test that it works properly. If you never used Soldering Tool before you probably will be better off with getting some help from certified electrician - it still will be less expensive than getting this fan ordered every year from Danby.

you must try from insyde, all my model's have acces from inside. you dont have a seal, remove carrefuly to not bent somethig and it will be ok. I presume that fan is an tangetial fan (that kind of fan have all my wine cooler's) you will need a screwdriver phillips and maybe a wrench.

Called Danby customer service. Requested repleacement part of lower fan unit. Located at bottom right on back of unit. Part was $6.68 plus shipping. Less than $10 total. At my door in 3 days. Plug and play piece that was easy to change. A very cheap fix and I hate to think what a service call would have been. Danby ph # is 800-263-2629.,

The problem is likely with one of the two fans. A new fan is available from Danby (1-800-263-2629). My noisy fan is the condensor fan located at the bottom rear of the device. After removing the cooler from under the cabinet, the source of the noise was obvious. You will need to tell them whether it is the upper fan or lower fan. Leave the cooler upright for a few hours before you plug it in so that you do not damage the condenser. Price for the fan from Danby is $20.15 including shipping.

Does it have a compressor and does it run? If so there is probably a relay on that board that is bad or only runs with the compressor.
