How to fix the HVTB18DABB when a zone isnt cooling.

Hi fredmw, I noticed that you added your particular issue to the question thread about another Haier model, so I'm copy/pasting the same solution I posted directly to you too, in case you don't see it there. Hope this helps!

"For those of you who have problems with one or bothor your zones not cooling on the HVTB18DABB or similar winecooler/cellar, the problem lies the Peltier-style thermoelectriccooling module. The original part is "TEC1-12706" and information on itcan be found on google. Finding this or a similar part on ebay can bedone by searching for "thermoelectric cooler". If the exact TEC1-12706part 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 3modules...one to replace the bad zone I had, and then I'll have 2spares 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 Winecellar. You will see 2 big fans attached to two large heat sinks. (If aheat sink on the back does not feel warm to the touch, the the otherside is obviously not cooling, which means that zone is broken.) Removethe screws from the fan and the heat sink of the zone that is notcooling, and while holding the heat sink, pull the whole coolingassembly for that zone out. Dont be alarmed if you feel some insulatingfoam separating as you pull it out, its a tight fit so that is to beexpected. Once you have the cooling assembly out of the fridge, take itapart and you will see the square ceramic cooling module inside.(REMEMBER which way the module was oriented before you remove it, soyou know how to put the new one in.) Clip the red and black wires nearthe module and remove it from the assembly. DON'T wipe away any of thewhite thermal grease left behind on the heat sinks. If you have anyextra thermal grease handy (available at Best Buy, or online at siteslike newegg), apply an extra pea-sized dab to both sides of the newmodule. Put the assembly back together and splice the wires from thenew module to the loose wires left behind going into the back of theWine cellar. Mount everything back in place as before, close up theback, and youre done!

This is really a lot easier to do thanit sounds, especially if you're comfortable doing this sort ofthing...a few pictures would explain much better if anyone wants toillustrate.

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

    Awesome but my problem with this same unit looks like a thermistor just next to the fuse. The reason I say looks like is because is fry, so I have no idea. What is great is that the fuse remains good :-$ Anyways Stratfordq5 can you help me up with this particular problem ?? I try online but since the one that I got is a aftermarket one under the name of Aficionado Im a lil bit lost. It share the same model number though.
    Thanks ahead.

Yes , motor is bad . May not start , next time cuts off . The fan in the back by the compressor , is called the condensor fan motor . I would suggest cleaning the coils in front at the bottom , of dust , lint , pet hair , etc , before replaceing the fan motor . Also , clean the fan blade before reinstalling the motor .

SOURCE: Haier Dual Zone Wine Chiller - One Fan wont run

I have the same problem. When I first discovered this, both fans had stopped working and the temp for both zones was over 80. So much for the wine that had been stored there. After leaving the unit unplugged for a few days, the fan for the lower section started working again but the upper fan is still overheating. Haier customer service says too bad, so sad (I discovered this problem in the 13th month of ownership). I'm sure it is not worthwhile to fix this so it is going out with the trash and I'll look for a different brand for the next wine cellar that I purchase. Any ideas?

Hi ive just retimed my machine but now the bobbin thread isnt been picked up x i have a singer HD 4423 xx


That is generally a timing issue. The needle is arriving at the bobbin at the wrong time to intercept the bobbin thread. Be sure you are using a brand new needle.

Mzc64 was working fine, one night came home to every zone panel red. now the main panel says zone set up.... what happened and how do I fix it?


I know this is old but the answer may help someone else.

The keypad sounds like the mode 3.1 type commonly used onthe mzc units.

They say 'setup' when the communication between the mzc controller and keypad is lost, ie just the 12volt power is applied or the keypad is set to the wrong channel (channel is set on the back with a small rotary pot).

If its been working andnow isnt working thenthe channel wont be the issue as that wont have changed. Its most likely to be a fault with the cat5 cable between the keypad and the controller in particular the brown pair of wires asuming its wired as per spec, these are the 485 bus wires which carry the communication. The blue wires are infa red the green is earth and the orange is +12v supply.

Try unplugging the failed keypad at the back of mzc on the appropriate zone and swapping it with one of the other keypad connectors on another zone (check on the back of the keypad on the other zone that it is set to the same channel address as the one you ate swapping it with).

If the problem stays on the same keypad then you know the issue is with either the keypad or cable, if the problem moves to the other keypad then the issue is with the main mzc control unit.

If the issue is the controller then it will be a hardware failure which will need repairing by an engineer, i continue to repair these units on a weekly basis and this faulty is rare but could be one of 3 things 1) ribbon cable failue between control board and backplane 2) faulty backplane panel or 3) faulty control ic on control panel.

However its probably cable issue Between keypad and controller.

trust that helps.

How can you fix the under threading of a sewing


Check the ovious things first make sure you needle isnt broken... then make sure there isnt any thread twisted inside your bobin housing. make sure bobin is inserted correctly if those things dont help it could be an issue of timing in your machine... I work as an embroidery operator in a factory setting and those things usually help..

I'm not a fan of zoning but it sounds like they don't have the ducting done correctly. There has to be bleeder trunks installed in the unit because your are taking a unit that is designed to cool or heat a particular square footage and make it cool or heat a smaller area. This makes the unit way too big for the job you are asking it to do. If the ducting is improper, you are going to have issues like this. A lot of contractors will not admit that the ducting isn't correct due to the cost to correct it. I personally think (my opinion) that 4 zones are a little excessive. Sounds like you really need 2 units. It's hard to tell from my point of view since I'm not there to actually see what is going on. I would have a couple of different contractors come out and give you an estimate to fix the issue and then tell the installer to come and fix what they say is wrong.

Compressor runs and gets hot but does not cool unit


This product has been discontinued
i dont think many danby units are parts supported
more likely generic after market parts fitted by air con mechanics do the job
relay first might be a thematic one and an compressor motor fan relay
then check gas pressure

Haier Wine Cooler won't cycle on and off automatically


If all you are doing is messing with that relay and then it hits the right temp, change the relay. I think the failure is a coincidence.

Hi PixelPup....Although I am unaware of what types of fabrics/needle size/project (ie does it have batting or metallic/special threads) your issue involves a fault located above your needle plate with 2 points of interest in particular. 1) Appropriate Needle Size, Type and Insertion. 2) Absence of upper tension. When replacing needles, ensure that the groove along the length of the needle is facing you. For every day medium weight cottons, a universal size 70 or 80 needle is fine. However, ALL OTHER fabrics, especially knits, denims, stretch and very lightweight or sheer fabrics should be sewn with the specified needle types. Your local sewing retailer can help you with exactness if you bring along a swatch/sample when you shop for your needles. Please purchase your sewing machine supplies from a sewing oriented retailer. Needles AND Thread quality matter a great deal in the quality and longevity of your stitches. As for needles, I recommend Schmetz, and Viking for threads. Keep in mind that needles to get dull, and can easily acquire brays which may not only cut your thread, but damage your fabrics as well, and should be changed "regularly". I would guess that misthreading accounts for 95% of all sewing machine problems including lockups, needle breakage, and instant jams. The dial for your upper tension may have a "colored zone" for the universal tensioning starting point usually between 3.5 & 5.5, with the lower number for lighter fabrics, and increasing with weight. If you don't have a colored zone, begin with #4. Completely remove the thread spool from your machine. Ensure that your presser foot is in the up position, and begin methodically threading your machine, paying special attention when you reach the tension area. There are usually 3 or 4 'plates' that provide the tension, and rushed threading by experts regularly causes the thread to miss the discs altogether. The presser foot must be in the raised position, which releases the pressure on the tension discs enabling your thread to slide in. Why not be proactive and remove and rethread your bobbin as well, ensuring that your bobbin thread receives tension from the flat spring on your bobbin case. Unless I have misunderstood your issue, your problems should now be solved......good luck my friend.
