The purpose of a run capacitor is to accumulate an energetic charge from its source and store it, and release it whenever it is required by the circuit. 2444, 325P306H37M30N4X, 628318-308, RD30370; In stock. Without the run capacitor, the fan cannot turn. Features a round, molded case that protects it from oil, dirt, moisture, and grease. Measures 1-3/4-inch diameter by 3-inch height. Maybe the fan motor he replaced it with required a higher one? A single run capacitor supports a single electric motor and is commonly used in small air conditioners and microwave ovens; a dual run capacitor will support two motors, the first being a compressor and the second being a fan motor. Original part#: D147086P33 (CPT00692) In general, motors that are operated in hot environments or with little ventilation will experience a dramatically reduced lifespan on their run capacitor. If a Run capacitor goes bad, then a motor can turn on, but the running amperage will be higher than normal, causing the motor to run hot and have a short life expectancy. So now im thinking the original 2 stage capacitor is my problem from the start.
