The LiftMaster 27-17108 Heater Element is a genuine OEM replacement designed to keep select LiftMaster commercial door and gate operators operating reliably in cold environments. By providing localized heat inside the operator or control enclosure, it helps prevent condensation, reduces the risk of frost-related binding, and supports consistent performance in low temperatures. This compact, cartridge-style element measures approximately 3/8 in diameter by 3 in length, making it a direct drop-in for assemblies that specify part number 27-17108.
Use this factory-original heater element when restoring the cold-weather kit or internal heater circuit on compatible LiftMaster commercial garage door operators and vehicular gate operators. Installation should be performed by a qualified technician: disconnect power, position the element in the designated bore or bracket, and connect to the existing heater wiring and thermostat/control circuit as specified in the product’s service manual. Always match the original heater circuit’s electrical requirements and verify fitment against the parts diagram for your exact model; this component is not universal. For safety, avoid contact with the element when energized and ensure proper strain relief and insulation are maintained. No programming is required after replacement.
