Carrier Refrigeration Crankcase Heater – HT31AZ-121, 120V 200W – New Open Box
About this item
This is a Carrier-style crankcase heater, model HT31AZ-121.
It's a 120-volt, 200-watt heater designed to keep the oil warm in a refrigeration or AC compressor, preventing liquid slugging on startup.
It's new open-box condition—so it's been maybe tested or is just missing the original box, but it's in excellent shape with no functional issues.
It should include any accessories that came with it.
If you're servicing a Carrier unit or a compatible system, and the heater is shot, this is a drop-in replacement.
A crucial part for compressor longevity, especially in colder weather.
