Lennox 99K32 Overload
The Lennox 99K32 Blower Motor Overload is a critical safety component designed for high-performance protection of three-phase HVAC blower motors. Engineered with an adjustable trip range of 4-6.3 Amps, this genuine Lennox OEM thermal overload relay provides precise monitoring of current flow to prevent catastrophic motor burnout. When the 99K32 overload detects an amperage spike beyond the calibrated setpoint, it instantly breaks the circuit to isolate the motor from power, safeguarding the thermal integrity of the stator windings. This unit is a direct replacement for LEN99K3201 and is commonly found in Lennox CHA16 and KGA series commercial units. Its compact profile and reliable Heater/Overload manual reset functionality ensure minimal downtime for technical service calls. For contractors performing preventative maintenance or emergency repairs, installing this HVAC motor protection device ensures the system maintains its original factory specifications and efficiency ratings.
Key Benefits- Adjustable Amp Range: Features a versatile 4 to 6.3 Amp trip range, allowing for precise field tuning based on the specific Full Load Amps (FLA) of your blower motor.
- 3-Phase Compatibility: Purpose-built for 3-phase (3PH) power configurations, providing balanced protection across all legs to prevent motor failure due to phase loss or imbalance.
- Direct OEM Fit: Guaranteed physical and electrical compatibility with Lennox HVAC equipment, acting as a drop-in replacement for part number 99K32.
- Thermal Protection: Utilizes advanced thermal sensing technology to disconnect the motor before excessive heat can damage internal components or melt winding insulation.
How do I set the correct amperage on the 99K32?
Refer to the blower motor’s nameplate for the Full Load Amps (FLA). Use the adjustable dial on the face of the 99K32 relay to line up the arrow with the specified motor amperage to ensure accurate tripping sensitivity.
What causes a Lennox 99K32 to trip frequently?
Nuisance tripping is often caused by mechanical issues such as worn blower bearings, tight belts, or clogged filters that increase static pressure and motor load. Verify your voltage supply and actual amp draw with a multimeter to confirm the motor is operating within its rated limits.
Can I use this overload relay on a single-phase motor?
No, the 99K32 is specifically designed for three-phase electrical systems. For single-phase applications, you must use a dedicated single-phase thermal protector to ensure proper circuit interruption.
