Installed Generac Guardian, model 0055040, ser 5405735 in Jan 2010, by
local elect. contractor. Done well until Jan 2011 when a 3-county power
outage occurred. Gen. came on but no power for house. Gen. did not shut off
so manually shut it off. Called Elect. Contr. next morning. He indicated it could
be a "fluke" but sent electrician to found breaker thrown in Gen. Retested
gen. and everything seemed okay. Gen. has only about 14 hours counting
12 min. test each Saturday. The yellow light came on after he reset Gen. I
got it off later. Still concerned however that Gen. could fail again and the
electrician never bothered to even open transfer switch or look for loose
connections, etc. Contr. said he would call company about it about 1 month
ago. Last I ever heard. The night it failed, the "snap" was much louder than
it ever had been. Does anyone have idea what caused this?
Is this the first outage since unit was installed? This could be a installation problem with the control wiring.
Is your electrician a Generac dealer,If not you might want to call a dealer and have them look at it.Unit is still under warranty
