Any heating and cooling experrs out there

[Tribetime]

I had a brand new sheathing air conditioning unit for then in July and the furnace was working okay for a couple weeks and everything just stopped yesterday. It's like it has no power at all I changed the switch going to the furnace there is power getting to there. When you turn the thermostat up nothing happens if you turn the fan on on and not Auto nothing happens if I try to click on the air-conditioning unit nothing happens. I changed the batteries and the thermostat and that didn't do anything should I change the thermostat

1. Call a HVAC person. nt

2. +1

Coupd be a control board in system or lots of other things.

4. Yeah but the air conditioning unit and the fan aren't working either

That's the reason I asked on here until I can reach the guy who put it in in July in the meantime if there was something I could do I'm a service plumber and I've had helped people on this forum who had Plumbing questions so I was just seeing if anybody could return the favor

5. Not trying to be dismissive at all

Did you test wiring circuit at control board & after it in the circuit?

I'm not an expert at this, but one is sitting right here next to me

[SheltieLover]

6. Is there troubleshooting and/or schematic online?

[SheltieLover]

7. Both are controlled by the control board,

Which is connected by the thermostat wiring.

Possible fuse in control board is blown. There is a little 3 amp fuse in control board. Fuse is usually purple.

I hope this is helpful.

8. Thank you so much I'm just disappointed I can't reach the guy

Who put it in thank you again

[SheltieLover]

10. Yw!

I hope it is something simple you can rectify on your own.

My worst nightmare is for AC to fail.

[Tribetime]

12. Yeah I don't want to have to spend money on somebody else fixing

When I was just put in a few months ago I'm going to give the guy a few days he's been talking to other people customers within the last week so I'm hoping call he's okay

[SheltieLover]

15. For sure!

What brand is it?

They vary in how much customer support they will provide to consumers.

But worth a try to call troubleshooting or look for diagnostic videos online.

I would think the unit to still be covered under warranty, as it's really brand new.

[Tribetime]

16. Thanks for your help I just got it working I

I change the switch thermostat there is no fuse but I found where the wires came in and said 3:00 amp and it's like a switch and I pushed on it and the lights came on so thank you very much

[SheltieLover]

17. Congrats!

So glad you got it working!

[Tribetime]

18. 👍😁😁😁😁

[Tribetime]

3. Yeah the reason I'm asking on here is the guy that put it in

I have not been able to reach last night that's the first thing I did I was trying to see if anybody's would suggest anything in the meantime I have a plumber and I've helped people's troubleshoot things on here who have asked for help

11. If this was just installed in July, should be under warranty. Call the installer.

[SheltieLover]

9. Manufacturer might have troubleshooting dept you can talk to as well

The company who made my ductless unit does & will walk consumers through diagnostics.

13. This is a long shot but check the a/c float switch. nt

14. I have no advice, but a question

What is a sheathing a/c unit?

I just had a new furnace put in on Tuesday. I opted to not have the a/c unit replaced because where I live in Colorado evaporative coolers can do a pretty good job of cooling the house for a fraction of the price. Last year I only turned on the a/c unit one time, so I didn't think it was worth it to spend another $5500 on a new one.

I've never heard of a sheathing a/c unit. ?
