Fujitsu AC not running
Hi can anybody help,
We are looking at a Fujitsu AOY54RBA3L split with an underslung inside unit. I have the three phases to the outdoor unit and also the single phase to the indoor unit, the fan run's indoors but the control signal to the outdoor unit is only 120v is this right or should the signal be 240v.
Any ideas as to why the compressor will not run
Cheers

Are there any fault codes showing on the controller?

Re: Fujitsu AC not running
I do have a fair idea why it does not run as this i right up my particular street of expertise, however due to certain recent redundancies i would not urinate on someone who calles himself/herself "TEAM" york if he/she were on fire.
Do what i do, get a meter and figure it out yourself.Takes a licking, keeps on ticking.

Re: Fujitsu AC not running
If you want to know the right voltage weather it is 120 or 240 v. then simply check the contactor voltage ,if it is 240 v the the signal must be 240 .IF you find that the voltage must be 240 and you have 120 first check the wiring to the indoor unit carefully specially the ground wiring,after all check the control board you will
find may a relay controls the signal to the outdoor unit
check it ,almost it runs by 12 V. DC if its voltage are correct then the possibilities are open .

Re: Fujitsu AC not running
I believe that the Fujitsu control signal is always 120v at all times. Something to do with fuzzy logic.
As for the comp not running then there may be a fault within the pcb. Good luck!

Re: Fujitsu AC not running
Thanks for the help lad's I got it sorted in the end, dodgy discharge sensor.
As for slingblade, it's Yorks policy to cut out tossers, any decent engineer would have been relocated or another company would have snapped you up. Redundancy is a part of life GET OVER IT!!

p.s. congratualtions on mending a split a/c unit, these can be very tricky indeed.Takes a licking, keeps on ticking.
