Argo Six Zone Control Switching Relay - Radiant Heat - Buzzing

We have an Argo Six Zone Control Switching Relay [ARM-6P] that is buzzing like crazy.

It used to just buzz for a little while then stop, now it buzzes a LOT especially before the furnace kicks on. The red 'priority on' light comes on when it buzzes. I have tried removing one by one the 6 little circuit plug-ins, but that didn't matter. We replaced the main relay but that didn't help either. Is the entire switching relay in need of replacement? Thanks.
