Learned a lesson, twice, in the last few days.. kinda 'wordy' post, point made at the end..
First time.. My AC wasn't working(outside unit wasn't kicking on).. everything inside was good, including heat(gas).
I'm not hvac but figured I could find the issue before paying someone.. suumertime isn't too far off..
Pulled the panel on the outside unit and 'looked'.. the capacitor wasn't puffy, the contactor was 'contacting', the motor spun freely, the 'freon' seemed to have plenty of pressure(no gauges, just pushed the schrader valve for second)..
I checked voltage at the contactor in and out( black to ground- 117vac, red to ground- 117vac)..
Replaced the contactor.. nope..
Replaced the cap.. nope..
Called my brother, 'did you check red to black on the contactor in.? nope.. 0vac
Turn out it was a bad .410 gauge shotgun shell looking 'slow blow' fuse on one main.. the 117vac I read was 'backfed' .. no 220/240
Second, just yesterday..
Alarm tech for my company said he has a bad wire or keypad on an install.. I went out to check..
Ohm'd out the 4 conductor, good.. checked voltage(why didn't he.?) 0volts
The new ac-dc transformer was bad..
Point.. lot's of members here offer help on so many things(mostly audio, but limited to that)
I read here everyday, post now and then.. AK is alive and well..!
Another lesson learned..
Pay attention to what you read..!!
