Reply to "Overheating Bridge Rectifier on TAS SAW Board"

Well, there ain't no way that 3.8ma is heating that bridge, are you sure that's not 3.8 amps?

Since it's a PITA to remove the triacs individually due to the construction, I'd replace all four and the bridge. What I do is reach under and cut the leads to all the triacs and then remove the leads from the PCB one at a time. I then mount the triacs on the heatsink and form the leads to slide into the PCB. Get the assembly all positioned with all the leads poking through, and then solder them all up.

FWIW, I'd also move the bridge to the bottom and bolt it to the heatsink as well.
