What details should you consider when repairing a Bosch wine cooler?
Many high-end wineries use Bosch wine cabinets when storing red wine. During daily use, you should pay attention to the status of the red wine, so as to ensure that the storage effect of the red wine is good. Previously, the Hong Kong Junhong Repair Center encountered a call about a red wine cabinet failure. The winery owner discovered that the cooling capacity of the wine cabinet had weakened, so Junhong immediately sent technicians to repair the Bosch wine cabinet. Next, we will use this as an example to share relevant knowledge.
1. Why does the refrigeration of the wine cooler become weak?
In fact, many winery owners will find that the refrigeration capacity of the wine cabinet has weakened after using it for several years. This is usually because refrigerant needs to be added to the refrigerant system. If the refrigeration capacity of the wine cabinet decreases in the short term or even loses refrigeration capacity, it is necessary to For professional maintenance and troubleshooting, the specific operating procedures are as follows:
(1) When repairing the Bosch wine cabinet, we must first check the status of the compressor. If we find that the sound of the commercial wine cabinet is very loud, it means that there is an abnormality in the compressor. In this case, the compressor needs to be disassembled to find the damaged parts.
(2) When measuring the compressor, you can use a multimeter to measure its winding resistance. The normal winding resistance value is 10-20 ohms. Abnormalities indicate that the compressor is faulty and needs to be replaced.
(3) After confirming that it is not the compressor that causes the abnormality of the commercial wine cabinet, look at the condenser and evaporator. For example, the surfaces of the condenser and evaporator of many wine cabinets that have been used for several years are very dirty. We need to clean them before checking. Many commercial wine cabinets have abnormal conditions. The red wine cabinet has too much dirt, which causes poor heat dissipation and affects the operation of the evaporator.
(4) If the compressor, condenser and evaporator are all faultless, then repairing the Bosch wine cabinet depends on the refrigerant system. If the cooling effect slowly decreases, then there is a high probability that refrigerant needs to be added, otherwise the leakage point must be checked. .
2. The red wine cabinet light strip does not light up.
I just introduced the case of repairing the Bosch wine cabinet and then explained how to solve the problem of poor cooling of the wine cabinet. As a commercial wine cabinet, a common problem is that the light strip does not light up. Although it does not affect the storage of red wine, the commercial wine cabinet is used as a winery. The display cabinet naturally needs elegant lighting, and the solution is relatively simple.
(1) Usually the light strips of the wine cabinet are composed of LED lights and are connected in series, so if only a single bulb fails, it can be replaced directly.
(2) If the marquee of the commercial wine cabinet suddenly fails and cannot flash according to the preset, use a multimeter to check the control motherboard and circuits, find the broken circuit and replace the burned parts.
The above introduces the common problems when repairing Bosch wine cabinets. If we encounter problems with cooling, we must repair them early to avoid affecting the storage of red wine due to commercial wine cabinet failures.
