I have 1.5 ton sharp window ac. Problem is that it doesn't work from around 2pm to 6pm everyday. It works normally otherwise and best ac cooling I have experienced. Compressor never switch off if I set temp to 16 degree but in afternoon if by chance compressor start then it work for around 10 min before shut off. I regularly clean coils and its not problem. Can this be due to low voltage? How can I diagnose the problem? Can I use cheap rs 150 millimeter from ebay to check voltage? Please someone guide me.
Ps. I recently changed my stabilizer to vg400
