Capacitor installation mistake The fan in our condenser outside stopped turning, so a technician came over, and replaced the capacitor.

It was running again, but was giving off a burnt rubber smell never happened before. The tech told us our motor needed to be replaced. Then, after a few minutes, the motor blew out. When he took it out to inspect it, it was really hot to the touch. Then, he checked a couple of things, and realized he had crossed the wires when he put in the new capacitor.

After he fixed this, the condenser seems to be running well, at least for now. He did say the compressor looks good. Could he have damaged the motor irreparably somehow shortened its lifespan, efficiency, etc? He sure could have shortened the life of the motor he's lily he didn't burn it out seen it lots of times with customers trying to do the work themselves.

If you connect the compressor...

Could this have also harmed the compressor somehow? In addition to the burnt smell, the condenser was making a loud, 'bad-sounding' noise, too, before the motor tripped. Originally Posted by khsuhc.

People change from either desperation or inspiration. I mean that the fan just suddenly stopped again. I'm guessing the motor didn't 'blow out' as he got it back up running again, could've just been an internal overload trip from overheating,.

This happens when the motor overheats and is supposed to occur before the motor heats up enough to damage itself.

If left in this condition yes it would eventually ruin the equipment. As far as shortening its life, yes that is possible, but then what did more damage: To clarify, it's not making any weird loud noises now--only when it was still miswired.

Did he leave you with a written warranty? If that motor gives up in the next 30 days who pays to replace it?

Condenser fan motors are normally hot to the touch. Thats not an issue. Without being able to ohm your windings out and take a amp draw on your fan motor its hard to say if he damaged your motor.

What do you mean by "your motor tripped"?

How to Wire a Run...

If this is a hobby application where you can tolerate the capacitor blowing up or leaking in the future, then continue on and be more careful next. Unlike the RUN capacitor, it is NOT designed to dissipate heat When the back EMF has built up to a high enough value, referred to as You can always go higher on the voltage rating of a capacitor but you.

on the Fan side of the dual capacitor could make the motor run backwards. Connecting to %s. If you have a start capacitor with a PTCR (Postive Temperature let me know the model number and I will be able to pull up the wiring schematic.
