what issues are you having?
Are you getting any codes? and have you tested low pressure switch
The low pressure switch is on the refrigeration line inside the condenser. If the refrigerant charge is too low it will not let the unit run. Or you can put refrigerant gages on to see the level
did you force a run to check pressure or we do not know what pressures are?
Bypass contactor, jump power...just like if you had a regular split and you wanted to bypass or press contactor in..
I am going offline now so I will see if someone can take over.
