I'm stumped. Have a wood boiler manufactured by Northern Steel (out of business)
which was a copy of Johnson Mfg in Wisconsin 22 years old. Has a switch that shuts the blowers off and turns on light simultaneously. Uses Ranco aqua stat
One day, turned the switch off to load, blower keeped running, also found the Ranco no longer shut down the blower. There is a relay in the circuit.. replaced, same issue..
Replaced three way switch, same issue. Called Ranco, said unit reached useful life ,
replaced. You guessed it , same thing. Ranco goes right past set limit, still displays temp .
Can’t find an electric schematic. Anyone heard of such an issue or possibility of a schematic of similar design? Thanks in advance
