:( Here’s my problem:

I have a basic thermostat. It's the one that has the needle on the right side.
I set it to 78 deg. And my AC unit will not turn off until it reaches 74 deg.'s:confused:

Then when the temperature gets to 76 deg.'s my AC starts back up again! :eek:
(hence with out the temperature reaching 78 degrees)
It seems to be on a timer depending on the temperature outside it usually
Runs ON and OFF evry 10-15 minutes.


Could it be that my thermostat may be going out?
Or does it have something to do with the blower and AC unit??



Any suggestions or tips? :confused: :confused:


Thanks in advance!

Mercury t-stat or snap contacts?

Mercury needs to be level to read correctly.

Look into an accurate thermometer, then adjust the readings on the t stat to match it,


Numbers on the stat don't mean a thing unless they are accurate, or just rub the #'s off anf put a warmer and cooler arrows
