Coleman Mach 15 air conditioners do not use a single universal start capacitor. Most units use separate capacitors: typically a 45 µF run capacitor for the compressor and a 7.5 µF capacitor for the fan motor. Some models also use a hard start kit, such as Coleman 8333A9021. To confirm the exact capacitor needed, the specific Coleman Mach model number from the rooftop unit label would be required.
