Meter Temp issue aside, having s new problem.
I noticed that my AC compressor cycle on and off at every 1 minute interval. On for 40sec, off for 1min and on again. Condition stays same in cold and hot days, and the cold setting is set to near hottest. The air con is still cold, just wanna check whether is it normal.
I suspect the air con gas is low or something is off? There is no sight glass for iswara LMST so I can't brain out whether refrigerant is low. How much for replacing gas, and probably replacing receiver drier and compressor oil? Any good recommendation on this (oil type/receiver drier original OEM)as I'm new to maintaining this system. Will need to get my belts tighten too.. suspect slipping of belt.
For my case, set "hottest" but on "on"la, like you. However that's on hot after noon, if it's on cooler weather or say, at Genting or rain, I need to off it manually (but keeping fan blowing la else it'll be stuffy) because it's too damn cold

Can check your system, as by right every 40k/2 years need to cycle the gas and oil.
Basically is "normal "in the sense that our cooling coils' thermostat isn't as intelligent as modern systems and the compressor clutch engagement is not very efficient.
For original systems I believe have sight glasses, else can just consider getting Denso Drier units and you get the sight glass lol.
I get mine done at uni car Denso Malaysia authorized shop.last I remember their full service cost 300-400, not sure if got raise price and that's before gst also.
Includes gas /oil, Drier, and removing your system /blower /cooling coil to clean them.
