two boiler controld go down at same time?
Hello, I am stumped, got a guy with two Buderus G234 boilers, one with 2107, one without, they are actually not tied together control-wise, a tekmar set point control operates the second boiler. Anyway both of the L8148E controls lost their transformers. I have never seen the transformer go (not that that's a big mystery) but to have both trannys drop at the same time seems puzzling.
I rigged up a 24v trans yesterday and got #1 to fire without blowing my popper fuse I had in line. I wrapped my wire 10 times around the amp claw and came with 1.1 amps during combustion (it was 11.7 amps with 10 wraps)
I replaced the 8148E
I didn't have time to get the second boiler going.
Any ideas what may have caused this? My only guess is a stray voltage surge grabbed the boilers circuit. I did not look at the elec service to see if there were two breakers or just one. I was in a bad hurry.
