Hello,Recently, my air conditioner broke and I hired a man to come fix the machine. Unfortunately, he did not help my situation and possibly made it worst.Initially, he informed me that my transformer was broken and so said that it needed replacement. However, when he replaced the transformer, both the transformer and the circuit board blew out. Now, he's making me pay, not only pay for his services, but also for the two additional parts. My question is: Is is possible that the circuit board caused this issue? Or did he mess up on the wiring and blow both parts out, by mistake?I just need to know, so I don't pay for something, originally not of my cause.Thank-you.
Either its wired incorectly or there's a brief within the cooling circuit. I advise placing a 3A fuse in front of the transformer. Comfortably splice it within the 24 v leg between the circuit board and transformer with two feminine connectors and the fuse appears just like the fuses that go into your car underneath the steerage column. The brief might be in quite a couple of extraordinary places probably the most located place for a brief in the cooling circuit is rotted out insulation on the thermostat wiring going into the condensing unit.
The Sandshark nailed it. Tell your handy man he's on the hook for the 3rd control transformer AND the 2nd circuit board. Then tell him to hit the bricks. Now do what you should have done in the beginning; call a qualified, COMPETENT technician.
It's possible that the circuit board developed a problem that caused the transformer to fail. So when he replaced the transformer, the defect on the board may have caused the new transformer to burn out. It's not too unusual for things like this to happen, so I wouldn't blame him right off the bat. The next step might be to have him (or perhaps another A/C service person if you're confidence in this first guy is shaken) replace both the board and the transformer prior to powering up the system.
Transformers don't normally fail for no reason. In most cases, something caused the transformer to fail, so it is incumbent upon the person servicing the unit to figure that out first before installing another transformer and powering it up. If it can't be determined what caused the failure, it is best to install an in-line fuse so, if there is an issue, the fuse will blow before taking out the transformer and the circuit board. Having said that, in a lot of cases, the circuit board has its own built-in fuse to protect the board from cases such as yours, so the board fuse should have blown before the board became damaged. I don't have much confidence in what your man did, so I'm more likely to blame him for blowing out your circuit board and the new transformer, unless he can prove otherwise.
