Is the system set to COOL? Is cool showing on thermostat?
Let's set system switch to COOL and use up and down arrows to set a desired temp, then immediately hit HOLD
Not even if you swing door open? I don't have a model number of the stat so operating somewhat in the dark here.
OK, this one is non programmable, so just set system to COOL and set desired temp
