Check coolant charging Check the compressor connection status and normal operation Check the obstacles around the indoor and outdoor units Check whether the outdoor unitservice valve is open Check whether the indoor/outdoor installation pipe/ wiring are correct Then apply these four readings to the compressor curve sheet. In the hermetic type, it can either be a scroll or reciprocating compressor.This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity. These compressors use terminal designations of W | V | U, as opposed to more traditional terminal designations like C | R | S. Generally, we analyze the windings to ensure they are in good condition and they are not compromised to the outer shell of the compressor (ground). After servicing, push the [push] button to return to normal mode. The windings should be of equal resistance. Without the knowledge to test each component individually we are blindly guessing. An inverter is a device which is used to convert between Direct Current (DC) and Alternating Current (AC). The same reading should be measured between any 2 of the 3 wires. This symbol is often near the same function as continuity on a multi-meter. The resistance for each test should be the same and will generally be around the .5 to 1.0-ohm range. Then check each terminal of the control board IPM [U | V | W] with the negative meter lead. 1. The inverter compressor technology is one that makes the compressor a smart one. Is it the indoor control board, the outdoor control board, or the wiring? Most inverter units utilize a rotary style compressor, though some on the market utilize scroll types. First it will tell you if the phase outputs in the inverter are operating correctly. BUT the compressor is cool and not running, the fridge is warm 70/70. You should receive a reading on your meter of 0.3-0.7VDC. The inverter compressor has a long service life and excellent performance The refrigerator is, perhaps, one of the most important appliances in the kitchen. Depending on how the signal flows through the IPM we will be able to determine if the IPM is functioning properly or not. Assuming you mean the actual compressor, they are treated like a 3 phase motor. An inverter drive works by taking AC voltage and first converting it into DC voltage, then the DC voltage is usually cleaned with capacitors and possibly a DC choke before it is connected to a network of power transistors to turn it into three phases for the motor. Inverter converts DC to AC. agar hum kisi Jaga Kam kr rahy ha or hum Inverter Fridge ya Inverter AC ka kam kr rahy ha to hamy isko check karny k liye 1 PCB kit sath rakhni chhahiye jo is ko chla saky kyu k ye Compressor low Voltage py chalty ha or agar ham isy Direct chala dy gy to ye jal jy ga. esi PCB kit jo is Inverter Compressor k mutabiq voltage bna k dy.
