Lennox 48G58 Contactor
The Lennox 48G58 Contactor is a heavy-duty, 3-pole electrical switch engineered for demanding HVACR applications requiring reliable motor and compressor control. Designed with a 24VAC coil (50/60Hz) and rated for a 25 Amp FLA (Full Load Amperage), this genuine OEM component ensures precise cycling and prevents accidental activation of high-voltage circuits. As a veteran technician knows, the 3-pole configuration is essential for breaking all legs of power in three-phase systems or providing additional control points in complex residential and commercial units. The Lennox 48G58 features robust silver cadmium oxide contacts to resist pitting and arcing, significantly extending the service life compared to generic 24v 3pole contactors. Whether you are performing a routine preventative maintenance swap or troubleshooting a buzzed coil, this direct replacement Lennox contactor offers the exact physical footprint and terminal orientation needed for a fast, clean install in HP21 and HP22 series heat pumps and compatible air handlers.
Key Benefits for Contractors:- Industrial-Grade Reliability: Rated for 25 Amps to handle the high inrush current of HVAC compressors without premature contact welding.
- Standard 24V Control: Integrates seamlessly with standard low-voltage thermostat circuits and control boards.
- OEM Fit and Function: Eliminates mounting headaches and wiring confusion common with "universal" 3-pole 25A contactors.
- Enhanced Safety: Effectively isolates power from critical system elements during the off-cycle to reduce electrical hazards.
How do I test if my Lennox 48G58 coil is burnt?
With power disconnected, use a multimeter to check for resistance (ohms) across the side terminals (A1/A2). An "OL" or infinite reading indicates an open, failed coil that requires immediate replacement.
Can I use a 2-pole contactor in place of this 3-pole model?
No. If the original equipment specifies a 3-pole 48G58, it is likely breaking all three legs of a three-phase load or utilizing the third pole for a specific internal control logic. Always match the pole count for safety.
What causes these contactors to chatter or buzz?
Chattering is often caused by low control voltage (below 24V), loose thermostat wiring, or debris/insects stuck between the contacts. Ensure the coil receives a steady 24VAC signal to maintain a strong magnetic hold.
