SOURCE: Fujitsu Heat Pump - problems

I had the same problem. The heater did not work in heating mode. However it was OK in air-conditioning mode. The operation light and the timer light blink twice and then the operation light blinks for 5 times followed by few seconds non blinking, then the cycle repeats again. I have read on the internet that you better unplug the power cord and then plug it again so that the heater re-sets itself. My only problem was that my heater is directly plugged to the power with no visible plug. So I went to the main distribution board and put off the power for about 20 seconds for the whole home. HOORAY!! The heater worked after that.

Check your filters. Manual says they need to be cleaned every two weeks under normal operation (and in my case more often during renovations). It seems it may not take much to limit air flow enough for the indoor unit to trip out. Hope this helps.

Check the disconnect switch and make sure that both the fuses are good and not shot. If one is shot then the system wont work. There are two fuse. Also be careful due to you will be working around 210 volts

SOURCE: Timer light on fujitsu heat pump flashes not heating

the light flashing indicates there is a problem. you can try reseting the system by turning the power supply off and back on again 30 sec later, if the same thing happens you need to count the number of light flashers and that relates to a fault code

Fujitsu ASTA12LCC WILL NOT HEAT OR COOL. GREEN TIMER LIGHT FLASHES TWICE AT INTERVALS. FAN WORKING. IS IT REPAIRABLE?


Serial signal reverse error. Basically the outdoor unit is not talking to the indoor unit. This is normally due to damage to the outdoor controller PCB and it needs to be replaced.

Fujitsu a/c outdoor model number AOTG12LVC indoor unit economy light flashing continuously, operation light single flash, timer light single flash this sequence repeats


Serial communication error. This means that the indoor unit is not communicating with the outdoor unit usually because the outdoor unit is faulty. You can check the indoor unit by switching it to 'fan' mode and seeing if all functions work normally (fan speed, louvers move as directed). If it responds normally, then it's probably ok so you can turn your attention to the outdoor unit. A common problem with the outdoor controllers is that they are susceptible to bugs, geckos, etc. shorting them out which will mean replacement of the board.

How to fix Fujitsu a1 error code for 15rls2 heat pump.


Try cutting power to the indoor and outdoor units for a couple of minutes. Restore power and see if the error returns. The A1 error for this line of units indicates high compressor discharge temperature, which translates to overheating outdoor unit.

If this error code remains after a hard power reset, it's time to pick up the phone. Either you have a refrigerant leak which has resulted in a loss of freon, or a blockage in the refrigerant plumbing that is backing up pressure in the system. Both conditions will require a major repair by an authorized service tech to get your heat pump up and running again. 25361378-awph1b3yhxdrnyqdcrsrelkr-4-0.jpg

Indoor fan slow to rotate in heat mode and no heat/compressor


The indoor fan will not run at normal fan speed untill the indoor coil reaches 32oC. This is done so that a cold draught is not felt when outdoor unit is not running. Check to make sure the outdoor unit is operating. If the outdoor fan is running but there is no indoor fan after 5 mins then you must likely have a gas issue or a fault compressor circuit.

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

Split unit, I get heat but no cold


I have run into this with the LG brand systems. try shutting power off to the outdoor unit to reset all units. If problem persists, it could have to do with a charge level of refrigerant (freon) or possibly a failed control board.

System will not start up.


This is a signal fault between the indoor and outdoor first make sure the dip switches are set start with the unit closest to the condensor set as unit 1 then next unit as 2 and so on the dip switches are inside the indoor unit on the pc board if you check the manual it will tell you which swithes to set, if this wasnt done when the units where installed they would have never worked i would also check the signal wiring between the wallmount and the splitter box / bc box and make sure there isnt a loose connection when you have ruled this out id say more than likely it is a faulty indoor board on the wallmounted unt
