Morning all,
On a call out to investigate the above chiller. I’m here to investigate further issues after changing a IGBT board at present. Goes through it’s VSD DC BUS precharge, compressor can be heard about to start then goes into the recycle timer then eventually gate driver too.
Circuit 1 say has gone into a gate fault error, as these common and any place to start?
Thank you in advance
