Wires to capacitor melted. What is the most likely cause?
I have a Bryant Coastal unit that had a cap replaced under a year ago. The unit failed again. I was told that the cap was o.k. but that the wires to it had melted and thus the cap had to be replaced. They theorized that it may have been due to a surge. The electrical service has a Leviton whole house surge protector that is showing green. I''m …
The role of capacitors and the cause of bursting
1. Capacitor quality problems. The quality of the capacitor is not close enough, and it can not reach the marked withstand voltage and heat resistance, which objectively causes the capacitor to work overloaded. A slightly longer time, or a larger voltage fluctuation, will burst the capacitor. 2. Heat dissipation
Power Supply Failure: 5 Common Causes and Preventions
Electrolytic capacitors can leak chemicals, which can then cause further damage from corrosion, eating away PCB traces, and other problems (see Fig. 2).

Circuit Board Repair: Common Reasons for PCB Failure
Many capacitors store electrical charge through an electrolyte paste. As capacitors age, this paste loses its ability to store electrons. As a result, the paste swells, causing the entire capacitor to swell and ultimately stop functioning. If you take a look at your PCB, notice any bulging components. These are most likely failed capacitors.
How do I fix a circuit that keeps blowing a capacitor?
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.
Capacitor Failures
In order to prevent capacitor failure and to use capacitors safely, it is very important to understand the causes and processes of capacitor failure and to take appropriate countermeasures. Failure of capacitors is caused by …
Clutch Troubleshooting: Common Issues and Causes

Common Heat Pump Problems: Causes, Signs, and Solutions
A water leak by your outdoor unit could be caused by several things. One cause is a cracked or broken condensate pan that allows water to leak out. Another is a dirty or blocked air filter, which causes restricted airflow to the evaporator coil. In this case the coils can freeze, causing water to spill out of the condensate drain pain.
induction motor
This combined with an applied mains voltage can cause rapid oxidation of the metal film. Measurement of failed capacitors show a value of about 1% of rated value. The seal must be air tight rubber, or a meniscus (lead) seal using the expoy the capacitor is dipped in. For this reason most film capacitors fail in an open state.
