CCR1036 temperature "issue" cause reboot.

Thu Jun 25, 2020 10:35 am

I want to share with you about a successful repair of a CCR1036-12G-4S.
It started with the power supply which had the original capacitors, the bad ones.
We installed a new power supply and everything worked as it should for two years. We started having temperature problems, at least what the router reported. This escalated as the router started to reboot due to the "temperature problems".
It reported very high temperature 100C for the CPU and 70C for incoming air, very high speed on one fan and low speed on the other. It also reported low voltage (~20v).
We started troubleshooting, in with a new power supply. nothing was changed.
Inspection of the motherboard showed that the capacitors C1442 and C1443 were slightly swollen. Okay nothing to lose, we tried to change them.
We soldered new ones with higher quality.
When testing the router, everything turned out to work properly.
I hope someone benefits from my story and don't discard their 1036-12G-4S showing this behavior.

Hi,

6 months ago we experienced exactly the same thing. CCR began to reboot and persisted even after the power supply was replaced. Optically, we saw that the capacitors C1442 and C1443 are inflated, so we had them replaced with new and better ones. Since then, everything is without problems.

Today, we preventively replaced another CCR in the data center. When we opened it, capacitor C1442 is inflated again, but it still works. As a precaution, we have the C1442 and C1443 replaced again with new and better ones.

Request to Mikrotik developers: if you use the same capacitors in today's CCR1036 models, please use some higher quality ones. It is a great pity that because of this the whole device stops working even in 1-2-3 years, while the device as a whole is of good quality. It spoils the good name of Mikrotik. Thank you for understanding.

I began to think we were the only ones.
Last week this happened again with an other router.
As you write, MT check your batches for those cap´s.

Hello,

If there are any hardware related issues, please write to support and provide at least device serial number.

Same problem on ccr1009, router rebooting every minute because of temperature error. 2 x 6.3v 680uf capacitors inflated. Also ether1 stoped working. After replacing capacitors all works ok.

Which ones did you get of good quality. Have a couple of 1036s with this issue that can be put to use.
