Lennox 93M14 Crankcase Heater
The Lennox 93M14 Crankcase Heater is a critical component for maintaining compressor health in high-voltage commercial HVAC systems. This 480V 40 Watts Crankcase Heater is specifically engineered to prevent refrigerant migration to the compressor oil during the off-cycle. By maintaining a constant temperature above the refrigerant saturation point, this heater eliminates the risk of liquid slugging and "foaming" upon startup—common causes of catastrophic bearing washout and valve damage in industrial environments.
Designed for professional installation, the Lennox 93M14 features a 6.3 to 8.5 inch diameter range, making it compatible with a variety of scroll and reciprocating compressors found in Lennox Elite and Merit series units. The 54-inch leads provide ample length for secure routing to the control circuit or contactor. This OEM Lennox replacement part (also identified as Lennox 100499-11) ensures the precise wattage required to drive off moisture without overheating the lubricant, preserving the integrity of the refrigeration cycle in cold weather conditions.
Key Benefits:- Refrigerant Migration Control: Prevents liquid refrigerant from diluting the compressor oil, ensuring immediate lubrication at every startup.
- Industrial Build Quality: Constructed with a rugged, moisture-resistant heating element designed for high-voltage 480VAC applications.
- Universal Diameter Compatibility: The adjustable tension design fits compressor shells between 6.3" and 8.5" in diameter for broad system application.
- Extended Compressor Life: Reduces mechanical stress caused by liquid slugging, particularly in low-ambient heating modes.
- How do I verify the Lennox 93M14 is functioning? A technician should perform a resistance check across the leads; an open circuit (OL) indicates a failed element. When energized, the element will feel significantly hot to the touch.
- Can this heater be used on a single-pole contactor? Yes, it is typically wired to the "hot" side of a single-pole contactor so it remains energized whenever the compressor is not running.
- Is this 480V heater compatible with 208/230V systems? No, using a 480V heater on a lower voltage will result in insufficient heat output, failing to protect the compressor.
