Fujitsu 18R1 crankcase heater installation




By garcia9053 on Nov 16, 2008

" "
An a/c tech removed the crankcase heater from my unit (AOU18R1) and doesn't remember how it was installed. How is the heater supposed to be installed and where is it supposed to be electrically connected?

- Sound's great if it hold's true. I live in south FL so cold weather is not the norm. However I did get the following from the Tecumseh web sight: " This heater prevents accumulation of refrigerant in the compressor crankcase during non-operating periods and prevents liquid slugging or oil pump-out on start-up". If this is true it seems that I still need to connect the crankcase heater. How is this done?

it really doesn't need to be reconnect unless you live in colder weather,it's job is to keep the oil in the compressor warm but if you live in warmer climate not a big deal
