Customer: replied 2 years ago.
the unit was working fine but no cooling
Expert:  Tim H. replied 2 years ago.
OK, I understand. The reason your light is not on is the blown fuse.
Expert:  Tim H. replied 2 years ago.
Did you have any other questions?
Customer: replied 2 years ago.
Why I am not getting cool air
Expert:  Tim H. replied 2 years ago.
That could be a separate issue. Is the outside unit running?
Expert:  Tim H. replied 2 years ago.
If the outside unit is running, check the larger of the two copper lines going into unit (called the suction line). This should be cold to the touch. If it is not running, check the circuit breaker and fuses for outside unit. I have to leave for a bit, but will check back when I return.
Customer: replied 2 years ago.
i touched it and it is not cold, the outside unit is working but the larger line is not cold
Expert:  Tim H. replied 2 years ago.
Then the unit most likely is low on charge.
Customer: replied 2 years ago.
what do i buy
Customer: replied 2 years ago.
what type gauge and hose i know is 410A and what pressure should i stop at
Expert:  Tim H. replied 2 years ago.
This will not be something you can just buy and take care of. First of all, as a person not certified for refrigerants, you will not be able to even purchase the refrigerant to recharge the system. Secondly, even if you had refrigerant, it requires expensive equipment to add and check pressures on the unit. And know what to look for when charging.
Customer: replied 2 years ago.
I did the course and is now certified for refrigerants but do not equip yet and no field experience yet, it i get the equip with some directions i can do it,
Expert:  Tim H. replied 2 years ago.
I'm going to opt out and see if one of our other experts can help here as I have to leave for quite a while. Please do not rate the question yet or reply back and this will go into the que for other experts.
