Why Crankcase Heaters Matter
When an HVAC system is off, refrigerant can migrate to the compressor crankcase and mix with oil. Upon startup, this can cause foaming, lubrication failure, and mechanical damage. The Lennox 11X27 40W crankcase heater maintains a safe temperature inside the compressor, preventing liquid refrigerant accumulation and protecting your investment.
Applications
Suitable for select Lennox air conditioning and heat pump systems requiring a 40 watt crankcase heater with a 4.85" to 7.09" compressor diameter fit range. Always verify compatibility using the model number before installation.
