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
