OEM replacement condenser fan motor run capacitor for Coleman Mach Mach-1, Mach-3, and Mach-15 rooftop air conditioners, including 67, 733, 737, 753, 763, and 833 Series models. Rated 7.5 microfarads at 370V AC, 50/60 Hz.
The 1499-5461 is the OEM replacement fan run capacitor for Coleman Mach Mach-1, Mach-3, and Mach-15 Series rooftop air conditioners. These are among the most widely installed rooftop AC units in the RV industry, spanning the 67 Series (6700s), 733/737/753/763 (7000-generation), and 833 (8000-generation) model families.
This is specifically the condenser fan motor run capacitor — the circuit that keeps the outdoor fan spinning to dissipate heat through the condenser coil. It is a separate capacitor from the compressor run capacitor used in the same unit. Fan run capacitors store electrical energy and release it in a controlled, steady flow to maintain consistent fan motor speed, stabilize voltage, and reduce the electrical stress that causes premature motor wear.
At 7.5 MFD, this is one of the lower-capacitance capacitors in the Coleman Mach replacement lineup — sized for the fan motor specifically, not the compressor. Common signs of a failing fan capacitor include the condenser fan failing to start or spin freely, the unit running but not cooling effectively, or the motor humming without rotation. Always verify the MFD value on the original capacitor before ordering a replacement.
Fan motor run capacitor rated at 7.5 microfarads and 370 volts AC — MFD value must match the original exactly
Covers the 6700, 7000, and 8000 Series rooftop generations across Coleman Mach's most widely installed AC product lines
Fan motor capacitor — distinct from the compressor run capacitor in the same unit; verify which capacitor requires replacement before ordering
Backed by a 90-day limited manufacturer's warranty
The microfarad (MFD or µF) rating of the replacement capacitor must match the original exactly. Installing the wrong MFD value — even one that is close — can cause the fan motor to run at incorrect speed, draw excess current, overheat, or fail prematurely. The 1499-5461 is rated at 7.5 MFD. Confirm this matches the label on the original capacitor before installing.
The 1499-5461 serves the condenser fan motor only. Coleman Mach rooftop units use separate capacitors for the compressor circuit. If the compressor is the component failing to start or run, this is not the correct capacitor. Identify the faulty component before ordering to ensure the correct replacement part.
Disconnect and lock out all electrical power to the air conditioner before beginning replacement. Capacitors retain a charge after power is removed — discharge through an appropriate resistor before handling. Note wire connections before removing the old capacitor and reconnect in the same configuration. Restore all shroud and panel assemblies before reapplying power and run-testing the unit.
