SUBJECT: Crank Case Heater Kit for Inverter Split Systems
For reliability and longevity, inverter condensing units are designed to maintain compressor oil
at optimum conditions while the unit is in stand-by mode. This feature allows a small current
draw through the compressor windings to maintain proper oil temperature to provide
compressor protection in preparation for the next run cycle.
In some cases, homeowners may hear a high-pitched sound coming from the outdoor unit. This
is the result of current draw through the compressor windings and is not a defect with the
inverter unit. If you have a homeowner experiencing this condition and finds it objectionable, we
have developed a kit to install an external crankcase heater to maintain proper oil temperature
instead of utilizing the compressor windings on the inverter units.
This kit is not under the manufacturer’s warranty and must be purchased by contacting your
service parts CSR. The part number for the kit is
