if you have a handyman tester use it to check the #2 rec and use a vom and check the snubbers on the spider block first.
The 2 rec's are notorious for causing issues like this, they will go out before the #1 does usually, this is why it is listed for the possible cause first before the 1rec.

When you use the handyman there is a test mode for hi voltage bleed thru , do that test and if you see the light light or even blip then replace the scr.

just make sure you double check all the connections before replacing any.

You've been swooped!
