I have 1 unit of old TOSHIBA Air conditioner model RAV-710LEP, 2 ton split, made in japan. My problem came recently. The unit stops automatically after 15 seconds upon turning it on. Then i will turn it on again. Then it will turn off automatically after sometime then i have to turn it on again. But surprisingly, sometimes there is not interruption or what. Could you please let me know on how to troubleshoot by simply sending me your answer on my email add mac21jst@yahoo.com. Thanks!
