Air Condition Repair Man Comes To Fix A Problem Doesn't Fix It But Causes Another HELP!!!?
Ok here's the deal, the blower fan on our central unit ran non stop even after the air conditioner had cut off, so we call a repair man to fix the problem. I wasn't here when the repair man arrived so my wife told him that the fan ran non stop. Well when I get home he's outside with the cover off of the outside unit, which had nothing to do with the problem the blower fan is what ran non stop we had no problems with the air conditioning unit itself. Well he comes back in to the inside part and looks for like an hour and finally says its a relay that he'll have to come back and replace tomorrow. Only problem is now that he left the outside unit won't run however the blower still runs non stop. He messed with alot of the wires although I'm pretty well read on the wiring of an air conditioning system, I can't figure out which to twist together to get the air conditioning to come on. I've tried touch the yellow and red wires in the tstat together, that doesn't work so it must be something to do with the wiring in the inside or outside unit. Is there any repair man on here that knows what he could possibly done to mess up something that wasn't messed up before. I wouldn't be so worried about it tonight because he's coming back tomorrow however I live in Georgia and its about 90 degrees in my house right now. Thanks. 10 months ago i took a picture and wrote down how he had the wires configured and didn't plan on telling him i had messed with it, and put it back like he had it before he arrived, he claimed he was supposed to have it running before he left today either way like i said i cannot sleep its like 90 degrees so i have to do something
Answer:
If I were in your shoes, I would not touch the AC unit any more. If the problem was only with the fan running non-stop, a relay could be the cause. By attempting to run the AC, you could possibly do more damage to the unit; and there is the possibility that he has disconnected the ac for a reason that you can not see. When he returns tomorrow with the relay, he should return the whole unit to good operation. If he does not, he would be responsible to make it right since the unit was cooling when he arrived. Your "tinkering" could be a reason cited for NOT returning it to good working order. It doesn't sound like he knew what he was doing. He should have had a fan relay in stock on his service truck. It sounds like the control board on the furnace may be your problem but since you are going to have to pay for the repair call, let him fix it. If he can't fix it, then check out my source for a step by step troubleshooting guide.
