Here''s what you can do once you''ve identified the problem: Replace the capacitor: Replace the blown capacitor with a new one of the same type, voltage rating, and capacitance. Repair any damage: If there is any damage to the circuit board, such as burnt traces, you will need to repair them.
Check the resistor in front of Q2 the transistor on the heat sink. Photo is not too clear, is it R5 or R6? it looks like some of the coating has blown off, it may well be open circuit caused by shorted switching semiconductors. Thank you for your answers. The capacitor probably failed, it is a 7 years old power supply.
Generally (!) it comes down to the specification of the capacitor. If you replace a poor spec one with another, then the same failure will happen. what circuit are you trying to improve? In general, a common reason for electrolytic failure is overheating; overheating is caused by excessive current.
Rule And/Or Policy Violation You never said if when you replaced the motor, if you also replaced the capacitor with a new one at that very time. If not, the bad motor may have not only damaged the first bad capacitor, but the 2nd new capacitor as well.
The capacitor is at the limit of its voltage rating (i.e., 6.3V on a 6.3V capacitor). For long life you should choose a cap that's at least 20%, or better yet 50% over-rated. If you're absolutely sure you can measure this without getting fried, check the voltage. The thing is running hot, and the capacitor is over its rated temperature.
Check the voltage rating of both capacitors and go with higher voltage, i.e. 25V instead of 16V. Thank you for your answers. The capacitor probably failed, it is a 7 years old power supply. I will now check the voltage of the capacitors and try to replace the faulty one and if I find trouble doing this I will just buy a new PSU.
Don't try to establish anything with measurements it if the cap is rated for over 63V -- in that case, there's likely to be potentially fatal voltages on the cap, and if you have to ask, you probably don't know how to stay safe. The capacitor is at the limit of its voltage rating (i.e., 6.3V on a 6.3V capacitor).

If your AC keeps blowing capacitors repeatedly, it could be a symptom of an underlying issue in the electrical system, such as voltage irregularities, short circuits, or a failing compressor or motor. It is crucial to have a professional technician diagnose and address the root cause of the problem.
A small capacitor that stores a voltage sample for the regulation section is often the cause, it can also be the resistor divider that sample comes from. It probably isn''t a difficult repair as long as nothing went bang on the primary side, check the secondary side rectifiers (Shottky barrier diodes looking slightly leaky is normal - but not ...
Install a capacitor with higher voltage and ripple current ratings (assuming it isn''t too big to fit in the case). Make sure the unit isn''t running too …
Below are some things you can do to prevent a capacitor from causing destruction. Reverse Polarity – If you are using polarised capacitors (like an electrolytic capacitor), double check, no triple check that you have wired it the right way before applying a voltage. Over voltage – This might be a simple solution be it''s worth noting, stay within the limits of the …
The insulation in the machine is what keeps it from having any sort of electric shock. If the insulation begins to decrease, there can be more frequent short circuits that cause the capacitor to fail. 7. Capacitance. The capacitance of a device describes its ability to store electric charges. Unfortunately, sometimes the capacitance can exceed the limit for a device, …
It''s annoying if your AC keeps turning on and off on its own. But it''s indicating your capacitor is in a bad state. Because of a bad capacitor, you might notice your AC is only working during the daytime but not at night. If you still have any confusion, use a multimeter. You can test your capacitor with a multimeter to conclude. 4 Other Reasons An AC May Stop …
Install a capacitor with higher voltage and ripple current ratings (assuming it isn''t too big to fit in the case). Make sure the unit isn''t running too hot due to insufficient ventilation or drawing too much current from it.
You need to put a properly rated cap into the circuit and then test to see if the circuit is operating properly -- and that means testing the key internal voltages. This may or may not be easy because you may not have a good feel for what those voltage should be.
A small capacitor that stores a voltage sample for the regulation section is often the cause, it can also be the resistor divider that sample comes from. It probably isn''t a difficult …
I tested the capacitor and it was bad again. So my diagnosis is that something is causing the capacitors to blow, in turn it burned up the motor. I am at a dead end not able to find out what would blow capacitors with a new motor. The motor has all the same specs and the capacitor is the right requirements. I''m assuming something electrical is ...
How do I locate the capacitor on my washing machine? Locating the capacitor on your washing machine can vary depending on the make and model of your machine.
