    Greetings Ya'll,

    I Found this group, while trying to find a Wiring schematic for an Ancient Carrier Split, Md. # 38CKCO48370.

    I'm not happy withe the way replacing the Condensor Fan Motor, Dual Capacitor, & Contactor went.

    The Replacement Condenser Fan motor is a "Mars" 10728, which Corken Steel, in Cinti., Ohio (Milford), said would replace the existing "G.E., 1/4hp, 208/230V./ 1.4 A./ RPM 1100/ CCW Rot.

    The Motor that they sent is 25 rpm Shy (1075), which I'm thinking is not going to cause Tremendous Problems on this 15 Year old Carrier Unit that My Customer wold like to keep going till next Spring, & then Replace it.

    The Problem that I'm Wrestling with, (& I've never set a gauge, nor tool, on this unit, because the Mother, now Dead, who I initially began doing work for 20 years ago, didn't want it.), is that after the Install, the Data plate RLA is 1 Amp shy & "some change" >>> Data 23.9A, vs, 22.6A.

    Voltage Supply is 230, with no drop across the Supply/ Load of the Contactor.

    Rotation of the New Cond. Fan has been verified as to the Old Fan.

    Ambient Temp was 82 Degrees, as was the home. Supply Air at 1st Register is 61 Degrees F., with R/A at 82 degrees F., (After 15 minutes Op.), & 64 degrees at last register with same R/A with distance between Reg. #1 & Last Reg. approx 35 ft. I have a Damn near "Perfect Temperature Drop" with a 15 year Old, "Improperly Installed" Carrier Split A.C.

    What is "Brain Trashing Me", is that I have 128 degree Condenser Air Discharge (Via Lazer), & 365 PSI Head.

    Something, be it what I've done in replacing the Fan, Dual Cap, & Burnt Contactor, ... Ias Wrong.

    Problem is, I'm wracking my brain, to figure out "if" it's related to the Original Install, which was Screwed up >>> No listed pad & out of level by 1/2", Disconnect is at 12" above Grade, & not fused, Unit is not listed for Modular Home Use, Line-set goes underground, in order to penetrate Home Foundation (WTH?!?), & I'm suspecting that a Proper Evac/ Pump Down, was not performed Judging by the Work-manship exhibited.

    I'm finding it HARD, to wrestle with the possibility that this Unit has been Supplying Satisfactory Cooling, for the home, over 15 years, at a Head Pressure of 365, at ambient of, as well as a "Load" of 82 degrees, ... With No Problems.

    On the "other side of the Coin", I'm Beating the crap out of myself trying to figure out what I did, that could possibly have caused this. I Told the Daughter of "My Original Customer", everything, & she said "Wrap it up, Figure it out, I'm Happy, Let me know what's going on.", & She paid me.

    I'm not a DIYer, & I've been doing HVAC/ Electrical/ Refrigeration/ Restaurant Equip. since 1982, & at this moment, .... I'd Seriously Appreciate any Advice.

    Since you've been in the trade so long, what would you do to a unit with high head pressure and condenser discharge air?

    I think wiring a condenser fan motor should be pretty straight forward if you've done this 35 years.

    I like to spin the condenser fan motor with blade attached and pretend it will hover slowly to the ground...from five stories up.

    if your a 35 year tech you need to drag up and get a job at Wal-Mart because you have lost it.


    This is simple shit. Not rocket science. He's how ya run that call.


    Step 1. Pull the fan motor and capacitor. Wash the coil.

    Step 2. Put a 1/3 hp reversible fan motor on and new dual run cap.

    Step 3. Check proper rotation and adjust if needed


    Step 4. Check filters, check the charge and adjust as needed.


    Step 5. Make out the bill.

    temp via lazer lol

    dude simple stuff whats the refrigerant in the system - hint its on the unit label

    and what jamesbrough said lol this is 2nd yr apprentice stuff
    and how do you think you get operating pressures with out putting gauges on it. put the gauges on it and find out the suction/discharge operating pressures, whats the liquid line temp?

    lastly - always got up 1 size when using a generic fan motor instead of an oem motor match the amps not the hp
