When a dual capacitor malfunctions, it can create a domino effect on the entire ac system. Issues like air leaks, clogged filters, and dirty coils can all stem from a malfunctioning capacitor. If left unchecked, it can lead to a complete breakdown of the system. That''s why it''s essential to address the issue immediately.
Learn MoreSome capacitors use "MFD" which stands for "microfarads". While a capacitor color code exists, rather like the resistor color code, it has generally fallen out of favor. For smaller capacitors a numeric code is used that echoes the color code. Typically it consists of a three digit number such as "152".
