The sticky at the top of this category
and the external links in this are very handy, but I wanted to update this thread with some 2013 findings for me.
I've been replacing parts on my Airstream's Armstrong unit and wanted to post my findings on replacement parts so others can use it as reference and I won't forget either
My specific AC details are below.
Summer Air Conditioner
Refrigerant 22 2lbs 2oz
Test Pressure 430 high Side 150 Low Side
Compressor 115v (volt) 60cy (cycles) 1ph (phase)
Comp. 95FLA (full load amps) 45LRA (load rated amps) or RLA (rated Load Amps)
Fan 115v 60cy 2.2FLA 1/8HP 1ph
Fusetron 15 amp (cool name, pun intended)
I will add 48Y Nema mount is used on these.
Previous owner replaced the original motor with a GE 1/4hp 3-speed, but used the original capacitor
Motor is on it's way out as it runs for 10 min then over heats till the thermal protection circuit kicks in. Either Fan only or with the Compressor running
I've torn the motor apart and the top mounted sleeve bearing has a plastic retaining gasket that is shot. This bearing is a bit stiff and likely the cause of the extra friction. Not worth pulling it all apart to repair so i'm replacing
What I find for the replacements for this motor is.
1/8hp CCW (counter-clockwise rotation)
Century Ral1006 (aka AO Smith) 48Y Nema mount @ 100 - 160 USD
Fastco D751 Though I hear this requires a kit #200 to mount. @ 130 - 160USD
Both of the above use a Run Capacitor using 370V 5MFD (microfarads)
DAYTON 2MDV4 Motor Run Capacitor 370V, 5 MFD, 2-3/16" Oval
There is a 1/6 HP, but most advise about increasing the HP of the motor.
Additionally there are others, but the above are a good starting point.
I see a compressor replacement in the future too. My clunks sometimes. but cost on these is now in the 300 and up range. I blame Alt economics.
It's cheap... till I need it.
