Langmuir just posted a thread about a batch of bad relays (their supplier changed relay suppliers). Just send them a note and they’ll ship out a new one.

We found that our wiring harness manufacturer switched sources for the relay and for whatever reason a percentage of them exhibit the issue described.
If you are experiencing this issue, please send an email to Support@Langmuirsystems.com and we will send you a new wiring…
