L8148a aqua stat trouble
I have that Honeywell aquastat and my boiler will not turn on I have no power at b1 or b2! What could be wrong? The circulating pump works though! Thank you!
Check for power at one side, then the other of the high limit and report back.0
I checked both sides of the high low switch no power on eaither side!0
The only thing else in the circuit is the relay.0
So I have to buy a whole aquastat or can I buy the high limit switch0
Not the hi-limit, the relay or connection at the relay. Pull up the instructions for that aquastat. It shows the schematic. I might be tempted to pop the board out and check the connections. If you do that, make sure you shut the power off.0
