Setting thermostat in the house I am able to feel air blowing, but the condensing unit outside is not working (fan not spinning - not "on"). I pulled fuses out and tested them - they are working - continuity. Installed 2005.
This will be a new adventure for me - (have totally pulled apart dishwashers and microwaves and ovens and a little work on furnace -- no a/c experience yet)
What should I look for next? For some reason I am a little intimidated at this one -- even though it looks pretty straight forward..Thanks in advance for the troubleshooting.:eek:

While I was waiting for anyone's input, I continue to investigate the issues. As I said, air was being blown out of the vents. Fuses working, but no sounds coming from the condensing unit outside. I tested the contactor and it did appear to have a "bug" in the contact. I replaced that and when I flipped power back on - I got that distinct humming sound - but no fan spinning. Which leads me to the capacitor. I don't know why I didn't do a visual check on this at an earlier time; but it is a little domed on top and I can now verify that there is power - so I ordered a new capacitor. Unless there is something additionally wrong with the fan motor as well, I think this will solve the issue. Will continue to update. So far only into this for about $35 for both parts and time...

The same problem happened with me when I was in Dubai. Then I contacted ac maintenance in Dubai. Then they solved my problem.

Unfortunately, I've experienced the same issue a couple of years ago. It's ended up I had to order a completely new unit from Lennox. We still had a warranty and it was covered so I was kind of lucky.

Talking about aircons... I'm allergic to dust, so I keep my apartment spotless. I do wet cleaning of surfaces few times a week. Recently, I've had difficulties with my air conditioner. I noticed much more dust in the apartment. I called a technician to check the aircon. He said that filters are dirty, so it needs replacement. I was looking for qualitative A/C dust cleaner. Long story short, I purchased a nice In-Duct Air Purifier and a guy from https://www.airconservicing.org/why-choose-us/ installed it in the aircon. Since then my allergy appeared much less. Also, I don't need to do cleaning so often anymore. Edited by user Tuesday, May 25, 2021 1:36:45 PM(UTC)

In general, this problem is caused either by a dirty condenser and fan or a clogged condenser. The condenser unit won't turn on: If your team doesn't turn on at all, you may have a faulty motor, or the unit may not be receiving power. When your outside AC unit is not running, sometimes it's as simple as an on/off switch being accidentally turned off. Most outside fan units have an on-off switch in a small box by the department. Circuit breaker tripped: A circuit breaker could have been the cause of your outside AC unit stops working correctly. Call specialists from airconservicingsingapore.com if you are unable to solve the problem. Good luck! Edited by user Friday, September 10, 2021 9:45:41 AM(UTC)
