Brad R for Model Number PFCS1PJXBSS Both fans running, not cooling. No clicking on motherboard. Compressor checks out ok, no continuity from the pins to the compressor body. Windings reading at 7 ohm Formed condenser assemble covered in thick dust. Cleaned that off Thought motherboard was bad so removed. Did not obtain a voltage reading to inverter before removing. Inspected board, no sign of soldier failure. Removed inverter. It is a pale green color, but does have brown spots that may indicate heating. Hard to tell. I thought I would be able to shake the resistors in the inverter to hear whether they had failed. This unit, everything is in the box (different than the initial video I watched). So, its either the motherboard or inverter, Which one? Anyway to check the inverter with everything disconnected? If I incrementally replaced one before the other to see if that took care of the issue, which one should I replace first?
Answer Hello Brad. You will test for power to the inverter. If there then you test for power to the compressor. If there is none, but there is power to it, you will need to replace the inverter. If there is no power to inverter, replace main board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
