Fan blows room temp air, I can hear the AC kick in but it only runs for about 30sec to 1min before cutting out and making a sputtering sound that shakes the whole unit. Then it just goes back to blowing the room temp air around again before trying to go back to AC mode. Only started to do this when the room temp was over 90F.

You missed the important bit 'air conditioner'. So it isn't chilling? Take it into a local refrigeration company. It probably needs a top up with refrigerant gas, but is may also be the thermostat. I trust you have is set to AC and not to 'Fan'?

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

Make sure the Thermostat is set correctly! The problem with mine was the temp in the house was colder than my A/C lowest thermostat setting.I had my AC temp setting on 66 degrees.The temp in the house was a little lower so the AC didnt kick on just the fan blowing cool air and no compressor working. The next day it was warmer out and the house temp was 79. So when I powered up the AC set at 66 i heard the compressor kick in and the AC worked fine.

The upper passenger side firewall has a little black line passing through it . Usually it is broken. There is also a ball on the drivers side firewall behind the hinge

Sounds like then fan has died or the run capacitor has die. All motors that run on single phase mains need a capacitor to start them spinning. These are quite cheap & simple to replace usually - worth just replacing if you feel you can't test it. Looks a bit like a 'D' cell battery with 2 leads hanging out. Could also be that the unit is not cooling/heating and the temp sensor will not activate fan until heating/cooling coolant has passed room temp. - Rick

Hello Rett Check the fan selector switch setting on the thermostat.It should be set to AUTO position instead of ON.

Since this seems like a fuel shortage problem amplified by slosh, it could also be the purge valve after the charcoal canister, that is supposed to let air in and out of the gas tank. Open the gas cap and listen for a "whoosh" when it is happening. There is not supposed to be any pressure difference.

It sounds like your air conditioner is doing what it is supposed to do. The compressor kicking in and out is an energy saving method of using the ac. When the thermostat (ball attached to evaporator coil) registers the set temperature the compressor kicks off.

A "Heat-Pump" is also known as a reverse cycle air conditioner, this means on heat the outdoor unit acts like the indoor section and vice versa. So in all probability you need to have it leak checked and recharged.

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.
