Normal ACs (non inverter) work in the following way
The AC compressor runs continuously till set temperature is reached in the room
The compressor then switches off, but the blower fan in the wall mounter unit keeps running. Durint this time the AC fan blows air out at Room temperature (which feels warmer)
When temperature of room rises then compressor starts running again. During theis period the air coming out from the inner uny is cooled by the condenser coils
And the process is repeated.... as long as you keep AC running
Ac works this way throught the operation period.
Now if you feel that your AC keeps switching off and on very frequently check the following
Your AC may be over powered for room *for example a 1.5 ton AC installed in a scenario where 1 ton is enough)
If there is voltage fluctuation in your area then the compressor may keep shutting don on large voltage swings
Solution: Get a Stabilizer
You have set the temperature setting too high. Max temp suggested for ACs is 25 degree Celsius, any higher will mean the compressor shuts down often. Remember every compressor shutdown and startup draws a high starting current
Set AC temperatures between 22 and 24 degrees Celsius
The thermostat/ Temperature sensor is faulty
Get unit inspected by Authorized technician
There is dust buildup on the outer unit / compressor unit. The dust buildup may cause overheating by preventing efficient heat exchange, This may lead to overheating of compressor and it shuts down to, prevent damage to itself
Get unit serviced by Authorized technician
The fan motor of the outer unit is not working properly
Get unit inspected by Authorized technician
Remember to get the AC serviced at least thrice a year to ensure smooth operation
Cool Thoughts... Cool Life !!!
First of all, fan on the tstat (on or auto) is referring to the blower fan not the outdoor fan. For the outdoor fan to run system must be set on cool and the setpoint temp must then be lower than the room temp. So what you are saying is the unit begins to work when you kick it??? Possibly you have a lose wire somewhere, check all connections outside. What type of checks have you performed on the capacitor?
How do you get it to kick in ?.Fid you spin it by hand ,if that's what you did and fan runs then you have a bad capicator. If fan runs fine in cooling and not in heat then you have a bad board
sounds like your compressor is not starting. Is this a split system? probable could be a run capacitor. Hard to say with out knowing what kind of system it is. Let me know and I will try to help you,
is the car running hot? some cooling fans never come on going down the road because the air comjng through the front of the vehicle keeps the car cool enough that it doesn't need to come on. but if it is overheating then you may want to check the cooling fan relay.
Threr are suppose to be two sounds comming from the window unit. One, the fan sound and the compressor sounds, (this compresses the refrigerants aove room temperatures (around 240*) & send it to the back coils and remove it to room temperatures and send it to the front coils which if enough freon, it will cool to at least 40*. Turn the thermostat all the way up or down while its off and see if you hear a clicking noise which tells you the thermostat is working which that what calls for cool. If it started loosing cools little by little, then you have a leak, and leaked all the freon out! If it stopped cooling all of once, then your compressor is not kicking in.
