Hey everybody! First time poster, just trying to troubleshoot a gas stove that doesn't like to respond to the thermostat unless I jiggle the wires that attach to this black box (pictured) I gather that this device some how causes the main gas valve to open when the thermostat sends the signal - but I can't for the life of me figure out what this is or how to find troubleshooting advice/replacement parts for it.
Picture of the stove and nameplate also attached for reference.
