8333A9021 Coleman MACH RV Hard Start Kit (88–108 MFD)
8333A9021 Coleman MACH RV Hard Start Kit (88–108 MFD)
Ensure reliable compressor startups in low-voltage or short-cycle conditions with the genuine 8333A9021 Hard Start Kit. This OEM package combines a high-capacity start capacitor and a PTCR (positive temperature coefficient resistor) start device to deliver the extra torque your Mach-series rooftop A/C needs to fire up smoothly every time.

💡 Technician Notes
-
Hard starts are especially beneficial when panels suffer voltage drop from long shore-power runs or generator use.
-
PTCR device automatically disengages after startup, preventing carry-on current and heat buildup.
-
Inspect old start capacitors for bulging or leaks before retrofit—this kit eliminates that worry.
-
Mount the strap securely to the A/C chassis and route wiring away from moving parts to ensure longevity.
