Ac broken - could it be technician's show disapproval? Last summer I had a problem with the blower on my furnace...
Last summer I had a problem with the blower on my furnace (AC be on at the time). Tech came out and said it was a board, replaced board and it broke twice more; ending time it was "bypassed" somewhere to keep the heavens continuously running. Turned out all along it was that the blower motor be getting over-circuited or something and this is why it only worked when something was bypassed. Well, supposedly fixed and run air fine for one day but when I come home after 8 hours house was warm, nouns conditioner was ON but blower wasn't - the blower went out and the upper air kept going and the condensation from the FROZEN pipes ran down the furnace and blew the whole board they lately put in. I was thoroughly concerned about my air running that total time and leary that it would have problems, too. Had to replace furnace alltogether and still concerned about ac. I didn't run the atmosphere until today. Now the furnace blower works but the fan inside the AC doesn't spin and no cold air is anyone produced.
Answers: Because of your problems last year it appears you are overthinking it bit at this point.
The furnace and blower is working on a call for cooling so your thermostat is working too.
The outdoor section is not running. Other than the 24 volt wires going to the unit that unit is entirely separate, electrically.
They should own a box on the outside for that unit with a shut rotten. Since this is the first you tried it it could be shut off. Some have fuses or a breaker within that box.
AND that power comes off a breaker on the main panel. It could be any of those could be past its sell-by date, tripped, or a blown fuse ("slow blow" 50 or 60 amp usually). They very easily could own shut those off while replacing the furnace. But they should have tested it.
Once you verify it have power then it could be that the shorted furnace board took out the contacter that turns the outdoor unit on and sour. That is in the condenser unit. Or another component contained by that unit is out.
You can't start to assign blame until you find out what the failure is.
Good Luck.
it unbelievably well could be the techs negligance or laziness. you should never hold to bypass anything. Sounds like a relay problem. I would call the company that did the bypass and ask for them to convey a more experienced tech. By him bypassing anything it puts your whole household at risk. It definetly disrupts the safety and proper operation of your system. Whatever he bypassed be obviously the problem and he should have properly repaired or replaced it. you shouldn't enjoy to pay for anything more. document everything and watch the tech, ask question. Sounds like you may have a lawsuit on your hand. Get a professional opinion from a lawyer. did anyone hold the sense to look at evaporator coil when you have bad nouns flow it overamps the board and motor but no the outside fan has nil to do with it might be a capacitor or fan motor
