Here is the latest in the saga of my A/C headache. Attached is a photo of a schedule I made of amp readings for both the front and rear units. The rear seems to be normal, 8 amps for compressor #3 and 11 amps for #4 when operated on high fan. The front unit is another story. Running at low fan, compressor #1 started at 13 amps, increased one amp per second, and shut down at 31 amps. I have to wonder why the 20 amp breaker did not trip. Running at high fan, #1 went to 23 amps and #2 went to 19 amps when #2 breaker tripped. In both low and high mode, after the compressors or breaker shut down, the amps were 4.6 until the thermostat was turned off. Note that the condenser fan makes a noise, but seems to put our sufficient air volume. Could a bad bearing in this fan cause the compressors to climb the amperage curve? Any help would be much appreciated.
