Question about Haier BC112G Wine Cooler

Haier Wine Cooler won't cycle on and off automatically

My Haier Wine Cooler won't cycle on automatically. Tapping the relay next to the motor causes the compressor to cycle. It then cools to proper temperature before cycling off. Once off it won't hole that temperature unless I tap the relay again.

We had a series of power outages due to the ice storm. Is it likely that the relay is shot and needs replacing ?

Re: Haier Wine Cooler won't cycle on and off...

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 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!

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.

I have a Haier model BC112G that stopped working. I unplugged it overnight and it still won't work. It just makes a clicking sound once in a while. Any Ideas? Wayne

Sounds like you compressor won't come on, check you warranty status before you call anyone. This repair can cost more than the unit did. The clicking noise is the overload on the compressor witch will happen if the relay fails (rare on this unit) or the compressor locked up. Either way, check warranty status on you unit before you call anyone, maybe cheaper to replace unit.... I hope this helped..

Cooler constantly runs

It sounds like it could be a thermostat problem. If it is a faulty thermostat, you will have to replace it as it will burn out the motor (compressor).

Wine temp on Haier wine cooler BC112G went to LL, opened up and some champagnes frozen, other wines very cold, condensation all over door, how do you fix this error?

The error is likely caused by a bad temperature sensor. The control board may still be Okay.
Replacing both of them is recommended.

Power surge caused wine cooler to quit cooling

Power surges, spike and brown-outs are a nemesis to small refrigeration units. The capacitor for the compressor likey was affected and possibly the start components in general, especially if the unit was operating when the surge occured.

Inside rear is icing up on Heir wine cooler

Surprised you don't get an "LL" error code for being too cold. Replace thermostat RF-7350-59 first, motor control next. Service manual out of print.

Want to purchase relay. Can't find part locally.

The best thing to do is go to your local appliance parts warehouse and match up the relay with what they have in stock.

Be sure to briung all relevant info you might have on the unit.

That way you can ask for the RF-5600-01 to compare it before purchasing. Thats exatly what a service tech would do if you called one, only they will charge you 50 to 100 bucks to do it.

We got a Haier 42 wine cooler. The motor doesn't run.

This is something you can not fix yourself. Remember it might cost as much as a new wine cooler to repair. As for free estimate on repait. That way if it cost to much your not out anything. Rus

Making clicking sound motor gets hot but not cooling

Your PTC relay on the compressor is bad needs to be replaced.

First be sure to unplug cooler. Remove the cardboard cover that covers most backs of the units. Remove the plastic cover that is on the side of compressor. It is held on with a metal clip. Now you should be able to see the relay pry the relay straight off. note the wiring and position of relay. Only three prongs on compressor. Go to a parts house for appliance's and with your make and model number should be able to get a new one. Let me know if you need any more help. ken

Haier Wine Cooler motor died

Yes, those motors shoudl be pretty standard stock items at any local appliance parts supply house found in the yellow pages.

You might also try lookinmg under "motors and controls" in the yellow pages. If you get it locally like that then you can physically compatre the old one with the new one to make sure it is indeed the same part.

Thats better than an online link with just pictures.
