$20 if you count the handful of 3amp fuses I popped trying to find the fault, the extra crispy lizard was apparently not the problem.
was the capacitor wasn’t it?
that was literally the last 2 times. This time it was the secondary coil on the contactor, had a short. Well i guess it’s technically always short since it’s a continuous wire but it was even shorter. Was getting about 2 ohms across the coil and i guess 10-20 ohms is expected and the low resistance was popping the secondary fuse.
and a few weeks ago the compressor fan sounded like a t-rex stepped on a lego so i flipped her over, unfortunately she wasn’t old enough for plugs so i just slowly let oil drip down my shaft and cranked it until i was satisfied. Now she doesn’t scream at me when i try to turn her on. I use arch btw.
Recently fixed my home AC, pretty sure the contactor was screwed and the capacitor was done for. Just poor maintenance by the previous owner. Bought the parts, rewired the thermostat because it was a nightmare of cables in the furnace, and in the process blew a fuse and messed up the transformer in the furnace. I didn’t have a replacement fuse so I jury rigged a bypass for now, got a new transformer that I tested and validated the output on, along with everything else in the chain, new contactor, new capacitor, and a completely rewired thermostat. Took a few days to fix.
In the process, I picked up an extra contactor, and capacitor, for the next time these parts inevitably fail. I need to go back and re-test all the parts, I suspect some may be ok, given that the wiring was such a mess, but I have no idea. I know the cap was definitely bad (bulged and leaking), but the rest might not be broken, they may have been malfunctioning by proxy of the bad fuse and wiring in the furnace.
Apart from fuses, I have everything and spares, so if I can validate that the transformer works, or the contactor is fine, then I’ll have extra spares. No worries.
Does your magic words require a degree to understand and practice or my dumb ass can learn the magic of fixing ACs?
being an electrical engineer has its perks, but the couple youtube videos i watched didn’t require any technical knowledge, mostly just safety knowledge, like the one hand rule and how to safety squint.
I replaced the capacitor after hearing the repair guy won’t be available till the next day. I already slept in the heat and didn’t want to do that again. Best believe I was strutting around the house in front of my wife lol.
For me it was $24 for a new oven igniter. That was three weeks ago and it hasn’t worn off, yet.
I spent more than a couple hounded dollars on servicemen to install some kind of delay between turning on the fan and the compressor, because the fuse kept triggering. It helped for couple days but the problem reappeared. Finally, I managed to fix it my self by simply tightening the wire at the fuse - due to bad connection, the connection was heating up, heating up the fuse and, since the fuse is thermal, the fuse was triggering.
I felt like a smug … idiot after that.
The fact that the serviceman didnt check something like that first tells ya a lot about some of those guys.
We like to think they know a lot about this sort of thing because they do it all day, but theyre just as dumb and bumbling as anyone else doing any other kinda job.
Can … Can you help some teachers out maybe? https://www.woodtv.com/news/grand-rapids/1980s-computer-controls-grps-heat-and-ac/
Probably, i think they need to get some other quotes though, that price seems pretty high for retrofitting some control systems, granted I don’t know how many endpoints they are managing from this single point of failure.
Bro install some fucking breakers
