Not sure if it's Tango Uniform yet....
Earlier, I heard this loud BANGING noise outside. Discovered it's coming from the outdoor unit. Turns out a two-prong plug on the fan motor came loose, got caught in the fan blade, causing the racket. {This is not the wiring running from the motor to capacitor. Not sure what it is actually...)
Reconnected then zip-tied to pvc tube carrying 3 motor wires. Turned on A/C again, outdoor fan spinning. OK..so back to work.
After awhile I notice it's getting a bit warm in the office even with a desk fan blowing on me. I look at the weather station readout: 83°F inside! Indoor fan is running. Outdoor fan is not.
Pull service panel off and feel HEAT coming out! Turn off 220Vac breaker in service panel. Top of compressor too hot to touch but not burning hot either. Bottom is hotter but not burn hot. I slowly pour half a gallon of tap water on top to cool it off. Top temp quickly drops; bottom not so much.
I remove 3 wires to compressor: C (common), R (run winding), S (start winding). I measure comp. terminal resistances as follows:
C > R: Open
C > S: Open
R > S: 3.5 Ohms.
A view of the schematic reveals a thermal cutout on both S & R windings. Given the above measurements, my thinking is both windings are OK however one or both thermal cut-outs are open.
Q: Do these thermal breakers 'reset' when cooled off or are they one-shot-only?
I have a fan blowing on the compressor to aid cooling and will recheck in a bit to see if I'm lucky today.
