Hi Folks,
I’m running into a problem with a Mikrotik CCR-1036 not powering on anymore.
The power supply makes a chirping/whirring noise and the capacitors look noticeably bulging with some leaking.
I already ordered a replacement PSU, but was wondering if anyone else ran into this same issue.
I’m hoping it’s not too far gone to be repaired.
Attached are photos for reference.
Why not just replace capacitors? Much cheaper, than ordering a new PSU… Such PSUs usually work fine after replacement.
Capacitors bulging/leaking (especially in power supplies) is common enough, but normally the issue “ends there” i.e. normally there is no damage done to the main board nor to the rest of the PSU circuit.
Personally I would:
Specifically the CCR-1036 PSU’s (it may depend also on model/revision) are known troublemakers, JFYI:
We’ve had several of those PSUs fail in 1036s. We usually just replace them. At least so far we haven’t had a replacement fail, but they might need another year or two of service to equal the lifespan of the originals. If those fail as well we might not have any choice but to repair them. I’m not sure we can get the replacements anymore. I suspect it would be possible to hunt down a suitable 3rd party replacement as well, but hopefully we won’t have to.
After all it is a “plain” 24V 4A PSU, not rocket science, you can also use external power bricks, they are common because quite a few monitors/TV’s use them, besides low voltage passive PoE, but really, replacing the capacitors is easy, cheap and works in most cases.
The original one should be 17x7x4.5 cm, so rather bulky, I think most reaidly available no-name ones are smaller than that.
