Genuine Coleman Mach replacement hard start capacitor designed to provide additional starting capacitance for dependable compressor startup in compatible RV air conditioning systems.
The Coleman Mach 1497-6881 is a replacement hard start capacitor designed for use with compatible Coleman Mach RV air conditioners and heat pumps. This capacitor provides additional electrical starting capacitance to help the compressor overcome the initial load required during startup.
A properly functioning start capacitor is an important part of reliable compressor operation. When a capacitor becomes weak or fails, the air conditioner may struggle to start, produce a humming sound without the compressor engaging, or experience repeated startup difficulties. Replacing a faulty capacitor can help restore proper starting performance when the capacitor is determined to be the cause.
Common symptoms of a faulty start capacitor include difficulty starting the compressor, humming during attempted startup, or visible swelling or leakage from the capacitor body. These symptoms can also indicate other electrical or mechanical problems. Always disconnect power before servicing the air conditioner. Capacitors can retain a dangerous electrical charge even after power has been disconnected. Inspection and replacement should be performed by a qualified technician.
For RV owners looking to further reduce the electrical demand during compressor startup, Coleman Mach also offers a Soft Start Kit (part #1497-3601), designed to help reduce starting current on compatible air conditioning systems.
