Check your thermostat setting, if the setting is ok then something wrong with your thermostat control.

change your temperature sensor, it's broken and it's going to down temperature

Hey all,

For those of you who have problems with one or both or your zones not cooling on the HVTB18DABB or similar wine cooler/cellar, the problem lies the Peltier-style thermoelectric cooling module. The original part is "TEC1-12706" and information on it can be found on google. Finding this or a similar part on ebay can be done by searching for "thermoelectric cooler". If the exact TEC1-12706 part cannot be found, then any similar part that's 40mm x 40mm in size, and 51 to 69 watts should do fine. For $25 I was able to get 3 modules...one to replace the bad zone I had, and then I'll have 2 spares in case the other zone, or this new one, ever go bad again.

To replace the part you must remove the back panel from your Wine cellar. You will see 2 big fans attached to two large heat sinks. (If a heat sink on the back does not feel warm to the touch, the the other side is obviously not cooling, which means that zone is broken.) Remove the screws from the fan and the heat sink of the zone that is not cooling, and while holding the heat sink, pull the whole cooling assembly for that zone out. Dont be alarmed if you feel some insulating foam separating as you pull it out, its a tight fit so that is to be expected. Once you have the cooling assembly out of the fridge, take it apart and you will see the square ceramic cooling module inside. (REMEMBER which way the module was oriented before you remove it, so you know how to put the new one in.) Clip the red and black wires near the module and remove it from the assembly. DON'T wipe away any of the white thermal grease left behind on the heat sinks. If you have any extra thermal grease handy (available at Best Buy, or online at sites like newegg), apply an extra pea-sized dab to both sides of the new module. Put the assembly back together and splice the wires from the new module to the loose wires left behind going into the back of the Wine cellar. Mount everything back in place as before, close up the back, and youre done!

This is really a lot easier to do than it sounds, especially if you're comfortable doing this sort of thing...a few pictures would explain much better if anyone wants to illustrate.

These are actually great units, so I hope this helps somebody fix theirs!

SOURCE: THE UNIT DOES NOT COOL ANDY COLDER THAN ROOM TEMPERATURE.

does the compressor run ? if so you could have a low refrigerant charge, a sealed unit resrtiction, leak or defective compressor.

Hello,

Check the thermostat for temperature setting. Also check the condenser coils and clean them if found clogged with dust. Unplug the wine cooler and wait for a couple of hours before plugging it again. If you can hear it running or whining, perhaps the compressor is being overheated. Test various components such as temperature control knob, evaporator fan, defrost timer, compressor relay, overload protector and the compressor motor.

Take care.
