Hello all
Wondering if anyone here could give me some pointers?
At the very least this post should show up in search engine results so that others trying to figure out what the hell E1 means can possibly have more usable information.
I have a Kelvinator KSV70HRA split system a/c that's started giving an E1 error after turning on for ~1 minute.
E1 is rather annoyingly essentially a "shits broke, yo" kind of error that doesn't really delineate much. Basically all it tells you is that the indoor and outdoor control boards are not communicating.
The user manual, as I'm lead to believe since I haven't been able to locate it (yet), states that E1 = call technician, as stated by other users on the net with similar dramas.
The fault seems to have coincided with a recent thunderstorm, that involved multiple downed power lines and trees everywhere remniniscent of an apocalypic distaer movie.
The problemAfter power cycling, the main unit will turn on and respond normally. The internal fan spins up normally, and the vents are clean.
Power cycling after leaving the unit off for a while has the same result.
The outdoor unit main fan does not spin, nor does it appear to even start. From what I can tell the compressors isn't starting up either.
What I've triedThe basicsPower cycling as above, but leaving several minutes in between.
Trying heating mode (in 34°C weather, a brave gamble) also had the same result.
non-basicshttp://www.filedropper.com/kelvinatorksv53hraincludesksv70hra which I snagged from manualslib
This is a diagnostic manual for my particular unit, and has very good information.
I have probed the signal/neutral wires, and see an oscillating voltage between 40-80V, which from the description indicates working PCBs. The outdoor and indoor PCBs both appear to be working.
All connection points so far have been snug. There is no obvious damage or dead insects/rodents causing a short.
The primary power inputs have continuity. The signal lines have continuity at least on the outdoor board.
There is a 250V 25A soldered-in fuse on the outdoor power board.
I haven't
yet probed the bridge rectifier, however I think I found at least one fault: the above fuse has no continuity, and appears dark on at least one side suggesting to me that it has blown.
I ran out of time at the moment, so I haven't probed the reactor or the internal fan capacitor, since it seems to be spinng up and blowing normally (ie not sluggish or intermittent).
SummaryIt looks to me like the main fuse on the outdoor PCB could explain the fault, since by all appearances the indoor unit is functioning normally and the outdoor unit plays dead, which logically the indoor unit is detecting as non-responsive and throwing E1 error.
Second question:
Any SE Brisbane folks know of a reputable a/c installer? So far I rang one bloke whom:
* Didn't care what model number it was, yet
* Was still able to tell me that parts are not available anywhere (I already found 2 sources for a replacement outdoor PCB of the correct model)
* Would be delghted to sell me a new unit
* Wanted my left nut for a call out
