OEM replacement blower run capacitor for Coleman Mach 679, 6537, and 6535A Series basement-mounted packaged air conditioners and heat pumps. Rated 12.5 microfarads at 370V AC, 50/60 Hz — maintains steady current to the indoor blower motor for reliable, efficient operation.
The 1499-5631 is the OEM replacement blower run capacitor for Coleman Mach 679, 6537, and 6535A Series under-floor basement packaged air conditioners and heat pumps. Unlike the larger compressor and condenser fan capacitors used in rooftop units, this is specifically a blower run capacitor — it serves the indoor blower motor that circulates conditioned air through the coach interior.
Run capacitors store electrical energy and release it in a steady, controlled flow to keep the motor running smoothly after startup. By maintaining a consistent charge to the blower motor, the capacitor stabilizes motor speed, reduces voltage fluctuations that cause wear, and allows the AC system to run for extended periods reliably and efficiently. At 12.5 MFD and 370V AC, this is a lower-capacitance unit than the compressor-side capacitors used in the same family of basement units — the correct MFD value must be matched exactly when replacing.
Signs of a failing blower run capacitor include the indoor blower struggling or failing to start, reduced airflow despite the compressor running, or a humming sound from the indoor section of the unit. Disconnect all power before inspecting or replacing any capacitor.
Blower motor run capacitor — lower capacitance than compressor-side caps in the same unit; MFD value must match original exactly
Specific to Coleman Mach 679, 6537, and 6535A Series under-floor basement AC and heat pump units — not for rooftop models
Rated for both 50 Hz and 60 Hz AC power systems
Backed by a 90-day limited manufacturer's warranty
The 1499-5631 is specific to Coleman Mach 679, 6537, and 6535A Series under-floor basement packaged units. These models mount below the coach floor and use a dedicated indoor blower assembly with its own run capacitor. This part is not compatible with Coleman Mach rooftop air conditioner models.
The microfarad (MFD or µF) rating on the replacement must match the original capacitor exactly. The 1499-5631 is rated at 12.5 MFD — this is the blower motor capacitor. The 679/6537/6535A basement units also use separate, higher-value capacitors for the compressor and condenser motor circuits. Verify which capacitor you are replacing before ordering.
Disconnect and lock out all electrical power before beginning replacement. Capacitors can retain a charge even after power is removed — discharge through an appropriate resistor before handling. Note wire connections before removing the old capacitor and reconnect the new unit in the same configuration. Restore all assemblies before reapplying power and run-testing the blower in all operating modes.
