Fujitsu 18R1 crankcase heater installation

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

Condenser motors all have oil in them. If the unit is overcharged with refrigerant and does not have an accumulator, (cylindrical canister)
the excess refrigerant can force oil out of the compressor as the
compressor tries to move liquid throughout the system. you will notice this as the system will not cool effectively.
Also if the compressor sump heater has failed (especially true for Tranes). The refrigerant will settle into the crankcase of the compressor and force oil into the linesets upon startup. This is the reason you should allow at least 20 minutes for the sump
heater to warm up the crankcase when installing a new outdoor condenser on a new system install. Hope this helps.

So far that sounds like the problem. Same situation I had with a new unit. The compressor went south. Changing it was a matter of a half hours work. If it has a warranty though, it may be worth the time and effort to call a pro. They will help validate your claim against the warranty. And if they are the fellas that sold the unit to you, well you may get the labor for free as well. If you do hit it your self, remember to have R-134 refrigerant on hand with the proper fittings. The compressor itself has only about 4 bolts and couplers. Good luck!

Have just installed a Fujitsu Asta 24lC air con heat pump problem


Hi Shannon,
I would pursue your fight with Fujitsu, normally their units are reliable:(
It could be a really simple problem or a really complex one ranging from many componenets. A air conditioner has many more components that people may think. Keep fighting to get the unit repaired will it is still under warranty, after that Fujitsu wont want to know you. It could also be a wiring and refrigerant fault. Call Fujitsu out again.
I take the time to answer your question, so please rate me.
Thankyou Mat

Will Not Heat


On the outdoor unit the fan should not be running, on the indoor unit the fan should be running. If you then check the outdoor unit with fan not running, you should be able to hear clearly that the compressor is actually working. If this is all correct, it is possible that your fourway reverse valve is seeping and needs to be replaced.
