Mars 11942 Capacitor

Product Description

The MARS 11942 is a run capacitor designed for use in HVAC equipment. Capacitors in this category store and release electrical energy to start or sustain motor operation in compressors, condenser fan motors, and blower motors. The 11942 is a direct-replacement unit intended for service technicians performing capacitor swaps on residential and light commercial cooling and heating systems. Installation requires basic hand tools and a multimeter to verify capacitance before and after the swap.

This capacitor fits into standard HVAC applications where a replacement run capacitor is required. It is suited for service calls involving failed or weak capacitors confirmed through capacitance testing. Technicians working on split systems, package units, and heat pumps will find this style of capacitor common in the field. Always verify microfarad rating and voltage rating against the existing capacitor and equipment nameplate before installation.

Key Features

• Run capacitor design supports continuous motor operation in HVAC systems
• Direct-replacement form factor for field service applications
• Compatible with compressor, condenser fan motor, and blower motor circuits
• Intended for use by licensed HVAC technicians

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light commercial HVAC systems. Verify microfarad and voltage ratings against equipment nameplate specifications before installation.

Installation Notes

Capacitor replacement must be performed by a qualified HVAC technician. Disconnect and lock out power to the unit before handling any capacitor, as capacitors can retain a dangerous charge even after power is removed — discharge the capacitor safely using a resistive discharge tool before touching terminals. Confirm the replacement capacitor matches the MFD rating and voltage rating listed on the equipment nameplate. Follow applicable NEC and local electrical code requirements.
