## Description

SPECIFICATIONS The capacitor is 1.97" in diameter by 4.13" in height and will run from -25 C. to +70 C. It is safety rated at 10,000 AFC. Fixes the following symptoms: As the capacitor gets older, the motor may get louder and seem to run slower. If replaced before they get weaker, it's possible to lengthen the life of the motor. Eventually, the capacitor will get too weak to start the motor and if the motor can't start, it can short out. Timely replacement of the capacitor is essential to Air Conditioning Maintenance. Safety tips for replacement: When replacing a capacitor, always be sure to turn off the power to the air conditioning unit and place a screwdriver between the terminals of the capacitor to release any stored charge. Our Capacitors are designed to be the correct fit, but it's best to measure the height and width of the capacitor to double check that the replacement unit matches the original. Count on our 30 MFD Run Capacitor for an unrivaled mix of durability, convenient functionality, and great value for money. Click ‘Add to Cart’ now!
