To test the PTC relay in your refrigerator, unplug the fridge and remove the lower back panel so you can access the relay, which will look like a small black box with 2 or 3 wires running into it. The electronics constantly monitors the temperature within the refrigerator and makes fine adjustments to the speed of the compressor accordingly via the inverter. The inverter controls compressor speed by frequency variation and by Pulse Width Modulation (PWM). From the outside, the inverter box looks like this: Whirlpool inverter box. we should check his Continuety with multi meter and check his value if we see Same value in every point that this compressor will OK and also check his shortage that … Q2. Now set the multimeter on ohm or resistance tasting or use an ohmmeter and check the compressor, follow the same method as we use for the fridge compressor terminal. However, let's see the example. ✔ Free Shipping ✔ Cash on Delivery ✔ Best Offers We have to have a PCB kit which will make the voltage according to this inverter compressor. WHIRLPOOL FRIDGE COMPRESSOR … These new generations of compressors on LG refrigerators didn’t prove themself as reliable. Because the digital inverter compressor gradually speeds up and slows down, it does not have to work as hard to manage the temperature. Then, use a multimeter to check the relay for open resistance. The compressor was replaced 5 days ago on Friday 1/4/2019. If there is visible damage to the compressor, you will most likely need to replace it. The twin inverter technology is a new generation of inverter compressors used in refrigerators. However, if you see damage to the compressor itself, you’ll likely need to replace it. After that find out the run terminal, in PTC relay the 2nd supply wire will connect directly to the run terminals of the compressor, which means that the 2nd wire connects to the relay point and that point supply goes to direct a terminal of the compressor will be your run terminal. After all, if there is no such need in a washing and dishwasher, as cleaning dishes and clothes can be done by oneself, then it is impossible to do without a system of preserving and cooling the products. wikiHow is where trusted research and expert knowledge come together.
