Power back on, but AC is not. How do I get the fuse? *PIC* *UPDATED FIXED*

OK, two neighbors with the same name brand have theirs already on. However, I'll stop playing with it for now and see if it comes on. The disconnect unit outside has absolutely nothing interactive, save the main switch. I see nothing else within it...

If so, the fuse is in that unit.

In most modern units there is not a fuse on the air handler. There is a fan on switch. Usually the breaker is in the main box and it is labeled as furnace.

Modern?
My unit is 8 years old and it has one.

Where is there a fuse and what brand? Do you mean breaker?

On the power supply. That would most likely not cause his problem (it could). A lot of old units have a large fuse. Sorry for the confusion.
 
Every unit I have ever seen has them. If they didn't and a spike got thru the breaker it would risk blowing the contact board a be very expensive to repair as opposed to a $2.50 fuse. I can't find a picture of showing the electrical installation after several google attemps and obviously and I not describing it very well. Perhaps Evadman will see this a chime in!

Skoorb has just failed HUSBAND 101.

:beer:

-edit- its a new house so pretty modern HVAC.
<---NOT an hvac guy.

but there should be:

Can you blow?
Can you cool?
Does thermo say to blow cool?
 
I just went up in the attic and I see no indication of fuses located in that area. I am almost certian they are outside but since IVAN is dumping buckets on us I think I'll stay inside.
 
outside.JPG <- that's outside, with my switch.

Thermo says to cool. Heat pump does not do a single thing when set to hot or cold; absolutely no lights or indication of life, period.

It looks to be on but to be sure it hasn't tripped...
turn it off then back on.

even if you turn the fan on?

if so then you ain't getting power to the blower (fan thingy that moves air)

Ah, my DC panel is the same. I have no visible disconnect - or anything like your setup anyway - anywhere.

Done about 10 times 🙂

Did you do the same for the breaker in your main panel?
Click to expand...
yep!
even if you turn the fan on?

I can't turn the fan on. Normally there are lights on the thermo. Tonight, none. Normally fan turns. Tonight, nope.

Battery in thermo?

[/quote]I didn't see one in it, but since it worked 8 hours before, I doubt it's a battery (?). It really sounds like a fuse SOMEWHERE...
