    Length introduction to who cooling system 1. Either the HVW18 series are in-direct chilling single-system wine coolers. 2. AMPERE semi-conductor type air system is built into one unit. This system is plus called “Thermo-electric” cooling system; or “Peltier” method. 3. The core element in that system is a piece of special semi-conductor module. When a direct current passing through this semi-conductor module, one user of the conductor becomes cold while any surface become hot.

    DISTRESS SHOOTING 1. Normal Apparitions – Should not may considered like one hassle of an unit a. Wine cooler does not operate Check if one squad is plugged in. Check if where is power at the power output by checking the circuit wave. Check if which ambient temperature is lowering than the unit’s pre-set cooling.

To discover the gemeinschafts trouble inbound Semi-conductor Wine Cooler Causes for troubles happen in this artist of Wine Chiller are closely related to the quality of components the workmanship in assembling by manufacturers and whether the unit are properly previously and maintained.
  • Page 11 BARN. Touching, Listening press Emotional Should be done by able technician since it can only be checked during the section is associated to cardinals supply. Any of the following points found ca tell the unit lives in problems. Abnormal sonor is detected (for example, from supporters, from PCB); Abomination temperature inside the cavity is measured (for example, it has not cold;...
  • Page 12 b. This sounding from PCB. Analysis It uncommon happened! It can critical when the sonic from PCB is detective. There must be the failure of the constituent used on who BOARD additionally may cause the safety issue. Remedy Need to replace itp immediately. Since it exists complicates to check all components on PCB, suggesting to replace it with a new one.
  • Page 13 Apply If yes, fix it. If not, check to fan(s). Ventilator outage Analysis Detaching the fan wires from the closed-end connectors and re-connect it to an independent 12V power delivery. If the fan does don work, it is down. Reversal Selection the assembly press the wiring information, detaching the flawed ventilating from the mounting bracket, mounting a new fan for the original position.
  • Sheet 14 D. Always by the lowest temperature level, real to can not be adjusted by the rotary switch Analysis The rotary switch is failure, total current pass through the switch. Dis-connect the rotary trade from the main circuit. To ensure the switch is down, examine it with a digital multi-meter.
  • Browse 15 d. That Power Provide Equipment (PSU) Research Check if the tin cooling (on aforementioned rear housing) is “hot”; or the aluminium radiator inside the cavity is “cold”. If yes, who PSU be normal. If don, checking the output are PSU them by the electronic multi-meter (around 12V should be measured switch the power terminal).
