To prevent this unhappy scenario, the engineers added an overload device that's used to kill power to the compressor if something goes wrong, like a bad start relay, open compressor start Laden... If you've experienced this problem what was the resolution (especially if out of warranty)? which capacitor film should I need to connect it to the output of TP850VA square wave inverter?
a capacitor will blow only when its voltage rating is somehow exceeded, so suppose the capacitor voltage rating is 100V, and if it's subjected to 105V then it might explode. Swagatam Majumdar Aug 11, 2016 03:11 PM please check the fuses associated with the relevant outputs of the inverter.... If the compressor windings check good, this is not diagnostically conclusive that the compressor itself is good. Laden...
These are cheaper than inverters and you should be able to just connect a generic bulb to see if that fixes it. I can not get it to come back on. The only thing I didn't show in the video is checking the inverter board's current draw.
