Question on my Sierra Air Conditioner made by Honeywell.?
Hi I have a Sierra Air Conditioner its made by Honeywell. I turn on the AC unit on and it wont ever turn off I have to manually turning it up to 88 degrees for it to kick off. It will run for hours if I dont turn it up. Does anyone know why or how to fix it to where it kicks off by itself?

i assume your talking about a window or wall unit if you take the front cover off there will be a bulb attached to the coils. that is your temr sensor make sure it is touching the coils if it is then the t-stat is bad you will have to replace it
