Toshiba air conditioning unit not working RAS-13UKH-G

I've switched off the internal power supply to hopefully reset the ac but whenever I switch it back on the operation green light starts blinking and if I turn the ac on with the remote, the yellow timer light also starts blinking. I couldn't seem to find any helpful manuals online for exactly this model so if anyone's got any ideas please let me know.

If the operation light is blinking, it means there is an error with the unit. The number of blinks can indicate what the error is.
Here are some common error codes for Toshiba air conditioning units:

  • Blinking once: Indoor unit room temperature sensor error
  • Blinking twice: Indoor unit coil outlet temperature sensor error
  • Blinking three times: Indoor unit coil inlet temperature sensor error
  • Blinking four times: Outdoor unit discharge temperature sensor error
  • Blinking five times: Outdoor unit suction temperature sensor error
  • Blinking six times: Indoor unit EEPROM error
  • Blinking seven times: Outdoor unit EEPROM error
  • Blinking eight times: Indoor unit remote control error
If you can determine the number of blinks, you can refer to the user manual to see what the error code means and what steps you can take to fix it. If you don't have the manual, you may be able to find it online or contact Toshiba customer support for assistance.

Model Yamaha ME-50 no power

With AC power off.
Use a meter (on Ohms scale) to check internal fuse for blown (open) fuse.
If you feel qualified & safe with AC Power On.
Check input to internal power supply on AC Scale (Caution when AC is on) for volts in.
Use meter on internal Power Supply for "probably" DC volts leaving internal Power Supply electronics to power the rest of the electronic circuits.
Switch mode power supplies can break down. They stop doing their high frequency switching so they don't convert AC to DC.
If this P/Sup is a separate box or circuit board, inside the unit, then it can have a part number & be replaced.
Good Luck

Red blinking and ac not working

If the power "flickers" and unit fails but will restart once the breaker is reset, this sounds absolutley normal. It is a safety device that keeps the unit from burning up things due to improper power being supplied. As long as resetting puts it back into service with no issues, don't worry about it.

Which can i conect the LED on the motherboar

As soon as power is switched on, mains via the UPS, the LED glows indicating that the MB is ready for action, plus an indication that the SMPS, internal power supply, responsible for converting the AC to DC(12V, 5 V & 3.3 V, both(+ve & -ve), IS working for the MB(3.3V supply to the MB) & the MB has successfully passed POST(only MB), ready for action.
I hope this is your query, else clarify the problem you are facing by posting it as a comment and I'll modify(try) the soln...........sodeep

Hitachi RAS 5142CHA Won't operate

Check the fuse on the control board inside the head unit,if its ok you need to replace the contrl board

Air conditioner stopped working

Check the breaker in the panel and the fuses in the disconnect at the outside unit. If that doesn't do it. call a heating and air technician instead of an electrician.

Hitachi RAS-25CHA will not work after power supply -brown outage.

I am an ex warrenty agent for Hitachi in Western Australia and I will be able to take you through some tests if you want. But from the sounds of it I think that you will be up for a new indoor PCB as these are the most common things to go when there are power failures. If you would like me to go through it with you let me know. But first where abouts are you in Australia?

Worked fine yesterday, today zilch !!

One computer I fixed had its internal power regulation confused. With the AC adapter plugged in, holding the power switch down for twelve seconds, then pressing it again, switched it back on. This sort of problem can come from a variety of causes, though. There is an internal power distribution chip which could have received a static electric shock or power surge and gotten cooked. The RAM could have gone bad. The socket where the adapter plugs into the computer could have been cracked loose. Check the power switch and then RAM first, and write more if that doesn't fix it.

Compressor for air conditioning does not run. no power to the unit, why?

Try reseting all the related switches and breakers. If this does not work you may need a professional to trace the power loss. Most commonly the compressor first pulls high amperage (due to an internal failure) then the unit will pop a fuse in the disconnect switch. The fuse can easily be replaced but that does not fix the failing compressor. You may want to call a professional in. Good luck:)
