I have, not immediately now, but recently enough to believe they're average clean.
Temp outside is now down a little, compressor is cycling normally, has pulled temp in coach down to 77 from 85 earlier. Current draw is down to 14-amps.
Couple things I'll try:
new filters in the morning
change capacitor
borrow a professional ammeter and see if it matches my HF cheapie
Also wondering this: I replaced the OEM Coleman Shroud with a MaXXair "TUFFMAXX" and the MaXXair has louvers in the rear, over the condenser area. The A/C kept running, pulled temp down, and amps dropped when I left the Shroud off. I'm about ready to get a tinsnips and take those obstructions out.
Beginning to think the Ole Mach isn't as sick as I feared...
