With the new motor came a new capacitor, so the two capacitor set-up is now gone. He ran a jumper across the 2 and 4 on the relay (high speed fan) and the blower fan ran. Like I said though, the outside unit does not come on, nor does the aux heat coils. The thermostat is new (DEC 08) and has been working fine, I don't think it is the problem but I guess it could be. Thanks for the replies so far. So if they try to hand me a huge bill what should I say? I don't mind paying for a new blower motor and capacitor, I am scheduled to deploy to Iraq again this fall so it is cheap peace of mind. I don't want my wife to have to go through this without me here. It is just the apparent lack of systematic troubleshooting (i.e. parts changing) and the numerous trips back and forth that kills me.
If you don't want your wife to deal with this again. You need to consider replacing the unit. You're not doing her any favors leaving her with such an old POS.
Well, the guy came back yesterday with the boss. They fiddled around and determined that it was the transformer so they left to go get one. They came back about an hour or more later with what they described as a universal (110/208/240) transformer but they seemed to lack confidence in hooking it up. When they flipped the breaker I heard a loud pop, some scrambling and cussing. I let them keep working at it and an hour or so later they came and got me. They had taken a 110 volt transformer (my unit takes a 240 volt) hooked it to a plug, plugged it in and connected it to the heat pump. They explained that this demonstrated the transformer was in fact at fault because the system functioned fine when supplied with 24(+) volts. They declared that the other transformer had blown for reasons unknown to them. They said it could be a short anywhere in the system ( I know this is B.S. because there is less than a foot of wiring between the breakers on the unit and the transformer) or it could have been a defective transformer. I asked if they could possibley have wired it up wrong but they said there was no way. So they said they could uninstall the motor, capacitor, and relay and put my old stuff back or I could keep them and they would cut me a deal. I said the stuff is old, the blower works much better what kind of a deal are we talking about? They said $x plus tax. I said fine (frankly I just wanted them gone) and they asked if I thought I could order and install a transformer. I said yes and I can. Unlike them I understand basic electricity and I can decipher a wiring diagram.
So I have ordered a transformer that matches the original and I'll put it in when it gets here. I also went back behind them last night and soldered up the connections for the new motor and checked everything else over. Two days and over $x dollars and I still have no heat. Good thing I have a fireplace with blower and a couple space heaters.
More to follow.

thats sad to hear that even the boss couldnt figure something like this out. If I were you, I wouldnt have paid them anything as they haven't fixed the problem yet. Your still w/o heat. At this point, I would just find the orginial installers of the equip. or find another company. Good luck, and I hope everything turns out ok in the end.
I would also reccomend that you not install the transformer, leave that to the pro's.

Tell me if I got this straight...
They installed a transformer. That transformer tripped a circuit and shorted itself out. They think it may be something else in the circuit that has caused the transformer to fail. They then tell you that you can install a new transformer on your own, in the same circuit that caused the last transformer to fail and when the cause of the last transformer failure is still unknown...
It sounds to me like you need to call someone else in to fix the problem.
... And when that new company comes get them to inspect that 30 year old heat exchanger for holes and cracks. There is no point in spending money on this unit if the heat exchanger is no good. By the time you fix the no heat problem and a heat exchanger you may want to consider buying a new unit.
Just my two cents...
Quickly, I must hurry, for there go my people and I am their leader!
