Is there a reset button on the outside unit
Expert:  BillyHvac replied 5 months ago.

there are 2 parts to the ac..the indoor blower and the outdoor ac unit. Where in the home is the indoor blower unit and do you have access to it?

Customer: replied 5 months ago.
Don't know where the blower is I changed the filters and there is nothing but a hole going down under my house
Expert:  BillyHvac replied 5 months ago.

Ok we will do a small test if your game before we get that far...can you remove the top section of the thermostat?...to where we can see thermostat wires?

Customer: replied 5 months ago.

Customer: replied 5 months ago.
The top of the thermostat is off
Expert:  BillyHvac replied 5 months ago.

now we want to take a short wire or paperclip and shape in a U

then hold one end on R terminal (may say rc or rh)

and hold the other end on G terminal.

tell me if the blower starts

Customer: replied 5 months ago.
There is an rc/0 and an rh/b and will a safety pin work
Expert:  BillyHvac replied 5 months ago.

use the Rc terminal...and yes a safety pin is fine

Customer: replied 5 months ago.
Nothing happens
Expert:  BillyHvac replied 5 months ago.

Thank you...

now here is what happens.

The blower under the house is where the thermostat power starts.

There are some units that are a one piece where all is together

Could you get me a model n umber from outdoor unit so I can tell

Customer: replied 5 months ago.
Model # *****
Expert:  BillyHvac replied 5 months ago.

Ok you have an all in one ....do you know where the breaker is in the electrical panel?

Customer: replied 5 months ago.
I've tried all the breakers in the house is that what you mean
Expert:  BillyHvac replied 5 months ago.

Ok,

How far are you willing to g on this? are you willing to get inside the outdoor unit?

On the unit outside or on the side of the house besides the unit is there a powwer box with a lever?

Customer: replied 5 months ago.
I already tried that is there a reset under the cover I can take it off just let me know what I need to look for please
Expert:  BillyHvac replied 5 months ago.

can you take a pic of these things for me and post here? Using the attach fileslink?

Customer: replied 5 months ago.
Okay
Expert:  BillyHvac replied 5 months ago.

terrific.

now follow that thick power wire to the unit. Remove the door from the section where this power cord enters. Take a pic with door off.

I will NOT ask you do anything dangerous

Customer: replied 5 months ago.
Okay it looks like some of the wires have gotten really hot and melted
Expert:  BillyHvac replied 5 months ago.

you are correct....

If we are lucky the only issue is that part..called a contactor. Of course the wires would need trimmed and cleaned up. But overall this is not a real expensive fix if the other parts are ok.

BUT this is 220 volts, so caution would be paramount. Are you wanting to try and fix yourself?

Customer: replied 5 months ago.
I think I got it figured out the wires are not even attached they have melted through thanks for your help gonna get my so to help me thank you so much
Expert:  BillyHvac replied 5 months ago.

You are very welcome...the part can be gotten for $20...

Just make sure the breaker is off at that power box.

Thank you for your patience and help!

Billy
