Wont cool below 50 degrees

Had no problems until i adjusted the temperature to ferment a lager beer at 45 degrees. adjusted to near 50 degrees for a few weeks and now the unit will not cool less than 50. the coils were really dirty so i cleaned them and still no change. if i turn the thermostat to off the compressor turns off. the fan works fine. its an older unit, the date on the compressor is 1993. i dont usually mess with the thermostat and i wonder if this is the problem or if i need to have the freon recharged. any help would be great because there's beer at stake here. many thanks.

Re: wont cool below 50 degrees

Seems like the T-stat may have a dead spot on it since it started when you changed the settings. It is possible to trick (short) the t-stat to cause it to cool FOREVER, that would check your refrigerant charge is good. Would lean more toward t-stat problem first.

Re: wont cool below 50 degrees

Check the seal on door, make sure its sealing properly, if yes check coils internal & external, make sure they're clean, check freon level as a last result

SOURCE: beverage air dd78e not cooling

change setting on thermostat and see if anything changes. If yes, that's the prob if no, freon level. start there.

You'll need to check the back-pressure on the low-side of the system, you have a faulty compressor. If there is a condenser fan motor make sure it is running when the compressor is on.

My fridge is not cold enough

You can't adjust the temperature? Owner's manual toubleshooting? No owner's manual try this:

Make sure the fan near the floor is working, Make sure the coils are clean, make sure the cooling fan intake is not blocked.

Beer freezes

The proper temperature should be between 35 and 42 degrees. Here are some things to try:

  • If your refrigerator temperature is closer to 35 degrees, try turning the temperature up slightly.

  • If the temperature is too low and you can't make it warmer by adjusting the thermostat, you probably have a defective 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.

Beer Not Cold!!!

There is a temperature control knob on the back side of the ref. it is on the bottom by the compressor
Have you adjusted this?

Cooler wont cool below 48 degrees.

Keep a thermometer handy. (adjust temperature control knob accordingly)
Periodically monitor temperatures inside your cooler. (adjust as necessary)
Keep the refrigerator door closed as much as possible to avoid temperature fluctuations

The temperature of the refrigerator compartment is
controlled by adjusting/setting the thermostat control
knob, located on the ceiling of the refrigerator
To start the refrigerator, and achieve maximum
cooling quickly;
• Turn the temperature control knob (using a coin
or screwdriver) clockwise to the furthest
(maximum) setting on the darker blue section of
the graduated control dial.
• Allow the refrigerator to run at this setting for 3~4
• When maximum cooling is achieved, turn back
the temperature control knob setting to the 2:00
o'clock position on the graduated blue control
• Correct cooling temperature is a key factor to
consider in storing and dispensing draught beer.
• Optimum temperature for serving draught beer is
between 34ºF ~ 38ºF.(1ºC ~ 3ºC)
• To maintain temperatures ranging between
34ºF ~ 38ºF.(1ºC ~ 3ºC) We recommend the
thermostat knob be positioned at the "2:00
o'clock" setting on the graduated blue control dial.
• To turn off the refrigerator, (no cooling) rotate the
control knob to the "0" position.

I have this same problem.  I have read discussions on this exact topic in several forums, and I have come across a link to a Haier Service Website.  When you go to this site login with password "HAIER" and UserID "HAIER" and look up your model number (my model number is "HBF05EABB)".  There is a "service bulletin" which provides instruction/pictures for adjusting the thermostat.  I have not tried this yet, but I intend to later tonight.  I like my beer a little cooler than 41 degrees!  Hope this helps.
