Unit wont start, flashing lights on indoor unit, fuse may be gone

The unit will not start. Has power, outdoor motor checks out o.k. The indoor unit fan runs, but the lights on the indoor unit are flashing indicating a communication problem. I believe the fuse is blown inside the indoor unit or so the electrician says. Should we replace the indoor unit or just a circuit board ?

How old is it? Can you justify spending lots of money on an older system? Sounds like a transformer issue. Sometimes if the low voltage wiring gets shorted outside via dog or weed eater it will short the transformer. But if transformer is on control. Controls are cheap at supply houses maybe not from technicians

After I replaced the pcb on my samsung air conditioner indoor unit it won't start and all 3 led's are blinking


I have had similar problems with Samsung. Apparently, the indoor board fits a lot of different models and each has to be "programmed" in to suit your model. Not sure what was wrong with your machine before but it has been known for these units to have a faulty outdoor fan motor which causes the outdoor board to fail as well. When this happens, the indoor unit will usually work fine for about a minute or 2 and then shut down, with lights flashing. The outdoor wont start at all. If these were the symptoms, I would suggest putting your old indoor PCB back and then getting a new outdoor fan motor and outdoor PCB.

The outdoor unit doesnt work for ac panasonic cs c9mkp,i have following the instruction on manual book.


After switching the indoor unit to cool, the indoor fan starts and the light flashes, lower the temperature setting to 16 degree centigrade. When the light stops flashing the outdoor fan and the compressor start, if not check the wiring connection going to the compressor contactor. Check if there is power supplying the holding coil of the contactor. If the contactor works, check the power on both contact points by using a volt meter. If the outdoor fan only works, you need to check line working pressure. If the standing pressure is low, compressor will not start.

AC unit Amcoraire AOS241HX @ startup i have power to the L1, L2 power inlet terminals to the outdoor unit but no power to the lines going up to the indoor unit. What can I do to correct problem?


these should be seperate circuits so lets forget the condensing unit for a moment. It should not come on because it gets the control voltage for the contactor from the indoor unit. Check your circuit board for a 3 or 5 amp fuse and make sure it hasnt blown. If it has you will get nothing past the board. If that isnt the case, you will have to start checking for supply voltage from the panel to the disconnect at your furnace, disconnect to board(transformer may also be bad) the blower motor. transformer, and circuit board are the only components indoor that effect the outdoor unit.

Indoor unit does not function -outdoor unit works


These units have circuit boards inside that have lights on them. These lights come on and tell you what the problem is. I have had 4 units do the same thing that yours is doing. The result has been that the compressor has gone bad. You have to get access to the control board to see the lights. There will either be one inside the inside unit or one inside the outside unit depending on exact manufacturer date.
Good luck and hope this helps.

Airconditioner wont come on


Does the indoor blower come on? If not you might have a low voltage problem in your thermostat circuit or blown breaker or fuse for your furnace which energizes the contactor outdoors. If indoor blower runs check if their are any fuses in your outdoor disconnect.

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
