Desolder the bad capacitor(s) from the board. Don''t immediately throw the bad capacitors away, we''ll need them for the next step. Also not the direction of the gray colored band on the side of the capacitor. The new capacitor must be inserted the same way. Wear eye protection sometimes the bad capacitors can explode because there under pressure.
Replace capacitors in about half the time ; Leave old caps in place, no unsoldering is necessary ; No more breaking traces during removal ; I''ve successfully repaired multiple power supply boards by soldering new
Testing in-circuit bad capacitors using an ESR meter. An ESR meter is a great tool for testing capacitors while still in-circuit. It requires minimal effort and no disassembly of the circuit board. If you don''t have these tools handy, it''s best to consult with a professional or take your device to an electronics repair shop. With the
The removed capacitor is examined. It can be seen that the plates are touching each other. This is bad. I suppose most people would replace the capacitor, but there is no need if it can be repaired. Somehow the shaft had moved back, forced by the tripod-like spring. The nut on the shaft, which held the shaft in pace, had cracked.
Will AC run with a bad capacitor? In many cases, AC will not run with a bad capacitor. The capacitor is essential for starting and running the compressor and fan motor.
