Mini split showing incorrect temp
 

The mini is starting to act up . It cools sometimes and sometimes it dont . Noticed if i flip the breaker and leave it off a bit it shows right temp. Makes me think theres a thermostat wrong somewhere i just have no clue where that would be located or if it is even able to be replaced. Any one have any exp doing that with these cheap chinese made units . Its the kozy kool 1ton. Installed it about 7 or 8 years ago.
