Cooling on and off (by 3 users)

wow, thats basically what the company told me to do:
Hello,    That rapid temperature drop as soon as the compressor turns on sounds like your temperature sensor may be loose. It is a thick black plastic wire located behind the filter screen on the top left. The sensor should be placed in a clip towards the front of the unit keeping it suspended between both the evaporator coils (the metal grating and copper coils you see) and the filter pre-screen and casing. If you feel comfortable you could check this and move the sensor between those two components yourself. I will need the serial number and the first and last name the unit was ordered under to check any further warranty options. Let us know if you were able to find the loose sensor or your order information. Have a great day.   Thank You,
Lauren

i will probably try it tomorrow as it's not too big of a deal at the moment (relative to the work i have to do). thanks for the response though, how in the world did you know that anyway?

also, as i mentioned, this is a 450z which i think is a newer model? the site says 13,000 BTU's if it makes any difference
