So the other wire will be the start terminal, otherwise, 2nd supply wire will be connected to the start terminal through a capacitor or heating resistor. You can diagnose problems with your compressor by using a multimeter, or a device that can measure volts, amps, and ohms. The twin inverter technology is a new generation of inverter compressors used in refrigerators. We use cookies to make wikiHow great. The control panel is usually located on the freezer door, which can be used to control the temperature of the freezer as well as the fridge itself. Then, use a multimeter to check the relay for open resistance. or switch of the supply which is connected to the fridge. *The image of the product are for illustration purpose only and may differ from actual product. Non-inverter fridge compressors are either on or off. Now connect one lead of the meter to compressor common and other connect compressor uninsulated body place.

Wenn Sie Lg total no frost refrigerator nicht versuchen, sind Sie anscheinend bislang nicht motiviert genug, um Ihren Problemen etwas entgegenzusetzen. A refrigerator with a Samsung digital inverter compressor consumes up to 46.9% less energy than a single-speed induction motor compressor, and thus contributes far less in the way of greenhouse gases. Especially we are enabling to give our customers technical support in order to provide best performance compressor through design … Part no: SRF014. Now test the compressor shortage between Compr.... terminals with compressor body like fridge compressor and if the meter showed no reading then compressor winding is no shortage with the body and if it's shown the reading then it means that compressor windings are shortage with compressor body. Current draw over nameplate rating would be a bad compressor. However, consumers benefit because they can save on power consumption when they use fridges working on the inverter compressor. Not only this, it comes with 10 year warranty and provides super silent operation. However, consumers benefit because they can save on power consumption when they use fridges working on the inverter compressor. As the compressor of the inverter slows down, the sound will be reduced as the fridge attains its ideal temperature. In the hermetic type, it can either be a scroll or reciprocating compressor. First of all plug out the fridge main electric plug. Changing frequency and PWM will cause an effective voltage … A platform to learn electrical wiring, single phase, 3 phase wiring, controlling, HVAC, electrical installation, electrical diagrams. The next step to test its resistance between one another. Why we use an overload protector with a compressor? Then see the relay and find out which one terminal is common, start and run. Part no: RHFR165. The problem i have is with some Hitachi units which just stop as soon as the compressor starts to ramp up. In this post, I am telling you about some main and common reasons for compressor not working and about testing compressor methods.

I already replaced - 3 thermisters (1 in FZ and 2 in FF) - the mother board (main board) The compressor still dead silent. Capacity modulation is a way to match cooling capacity to cooling demand to application requirements. Now if you check compressor motor windings and not find any problem and still compressor did not run then change the capacitor and if still compressor not working then check the overload protector. wikiHow is where trusted research and expert knowledge come together. wikiHow's. Assuming you mean the actual compressor, they are treated like a 3 phase motor. Product Sold Out. Sometimes when our refrigerator compressor stop working or not running a problem then we must call a professional to test the compressor or refrigerator.
