I got many atta boy awards over the years
Carlos, The centrifugal switch should be open when nothing is running (heat off ) remove wires from switch set meter to ohms and check an open circuit you get no reading. then start heat with wires
Carlos, What motor are you talking about???????? I was referring to the ventor motor ( removes flue gas ) that motor either runs or does not they turn at 3400 rpm so it would be easy to determine if
Raj, If your running only heat , you do not need Y and G at the t-stat hooked up. remove and tape bare wire ends those are for your A/C ( Y ) and G is for a air handler blower .you do not have that
Carlos, I would determine that the centrifugal switch is not stuck in the closed position first. Just because the ventor motor is running does not mean the centrifugal switch closes automatically
Raj, Just disconnect the low voltage wires from the t-stat at the boiler leave the transformer hooked and turn on power see if transformer burns up. If it does not your factory wiring is OK. Then start
