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

[spidey07]

so you have no power to your thermostat?

definately breaker (or batteries in thermostat)...it pulls low voltage from your blower.

unless its wireless and has batteries.

All the breakers have been reset multiple times!

Yeah, it doesn't look wireless, so it must be pulling power from the blower, which ain't workin 😉

Control (24VAC) is missing. Make sure your AHU is getting 120VAC. Make sure ALL of your appliances in your house are working and every branch circuit has power. You may be missing a phase!

Cheers!

No matter what the blower should come on. There is obviously no power going to the control circuit inside. Normally the breaker that feeds the AC/Heat is either one or two Double breakers. Sounds like a double breaker died from the surge. Time to get a meter going and measuring where power is lost.

Yes, that could be it. 120 might work and 220 might not. Good idea, sharkeeper.

hehheheehe

Skoorb use a multimeter (it is right next to your man card) to see if power is cominginto the airhandler. Your thermostat is supplied by the 24v circuit so if no power is getting there you will obviously not be able to use the thermostat. Check both the main in and the 24v circuits.

My power has been out since my last post. 🙁 very boring.

So presumably repairing that would involve taking the main panel off and looking behind for dead fuses?

You might have a leg of your 220 missing .....see if something like your dryer will work (if it's 220 that is).
If the dryer doesn't work right then I bet that's it.

My inlaw's had a power problem a couple of months ago and the lights went off and when they came back
on everything worked but the stuff like the AC and the Range and the Dryer.....ended up that one of the
legs of his 220 was dead and the power company had to come out and do something to the power line
between the transformer and his house.

Thanks for the idea, but I tried the dryer and it does indeed work ...

Ther are no fuses in the main panel. Ther are breakers. Take the cover off and see if you have 240 coming in.

So i'll need the multimeter for that then 😉 I will play again tomorrow morning. i've got 240 at least for the dryer, though it does run on a separate 2 X 30 breaker setup.

ummm, update?

It's still off! I'm going to unscrew the main panel and, presuming nothing seems out of place (like I'd know!) I'll have to call an electrician I suppose. I guess I will assume that the cooling is fine, and call a general electrician as opposed to an AC repairman.

EDIT: Actually I won't even bother unscrewing that thing, because if there are no fuses anywhere that I can possibly change, there's nothing I can do besides hitting breakers, so really somebody else will need to figure what the heck's going on.

Thanks all for responses, though 🙂

No call the AC repairman.

Edit: Doh didn't see update.

oh my...you actually posted the reason.

Brave man you are.

I knew that you guys would want to know. Argh, glad my parents were here - they offered to pay for it 🙂 Oh well it's better than something serious having gone wrong with it!
