It's getting chilly out, so I decided to run the heat and make sure it's all working properly before winter. We have a single zone Buderus GB142 boiler (natural gas), installed in 2006 or 2007. It has an outdoor reset unit that has been, at times, a bit flaky (turned out to be a loose control wire, easy enough to fix). But otherwise, it's been a pretty good boiler.
In any case, I turned on the programmable thermostat and waited. no heat. So I went downstairs, and both the outdoor reset and the Buderus are dead. The control panel on the buderus does nothing when it's turned on (normally you get a simple status screen with error codes, etc). The LCD on the outdoor reset is blank - no power to that at all.
The main power switch to the boiler is on, and that junction box also has an outlet for the condensate pump. There's power to the outlet. I tested the outgoing wire from the switch with one of those cheap electric sensors (the kind that beep when you get close to a live wire), and it's showing there's juice coming out of the switch.
In the past (I think, it's been a while), when the outdoor reset had a loose control cable, the boiler didn't turn on. I can't recall if the unit was this unresponsive though. I'm wondering if the outdoor reset unit is shot, or if it's something bigger.
Any ideas?
Thanks!
