Hello all,
So I have a Icepower 250ASP module that is not working properly - the Status LED flickers orange. I know its in protect and wonder if anyone has any advice other than "Replace it". I have a few 500A, 1000ASP, but sold off my 250ASP a while ago, and want to see if this can be repaired before just replacing it...
Any advice? I do not see anything burned out...thinking first to check the Rectifier and caps, then output transistors...anything else? Hoping there was a protection reset dip switch (yeah, dream on)...
I put it on a variac, as I had a another Icepower module (different series) that for some reason only wanted to work properly at mains voltage under 110VAC (Overvoltage max is around 135VAC-ish?)...it did flash green/orange at main voltages around 90VAC, but no real help...Also notice the good 250A LED stays green for 15 sec then goes out after turning unit off, while the bad immediately goes from Orange to off...maybe power supply caps or rectifier is best place to start...

Bummer...oh well, though I would ask, but these Icepower amps are unknown......
I am looking for a single 250ASP...anyone have one laying around? I have a few 200AC and 500A modules to trade...among other items (trannies, output transistors, etc)

Ha! Fixed it. new pair of 200V 680uf caps and she fired right up...had a feeling it was something simple. Put a hair dryer on the pair of bad caps (lowers ESR) and she miraculously started working (green LED) ....
Now on to fixing the two 1000ASP modules I have ...totally different problem tho (smoked output transistors, diodes, resistors, etc)...
