YVAA DC bus voltage imbalance
So as the title states I’m having a fault code on a YVAA, I called York tech suppourt and was not pleased with the language barrier. I’ll leave it at that lol. After troubleshooting I changed the bleed resistors just to be safe.
The chiller will run for 15 minutes, then 5-7 minutes then eventually won’t even pre-charge. Is this symptomatic of capacitor bank slowly overheating as each start occurs? I’ve checked all boards, incoming voltage, ohmd line reactors and megged each line reactor to ground.
I’ve found no issues and kind of stumped. A new drive has been ordered but wondering if there’s anything I can do in the meantime?
Thanks in advance!
