Furnace blower runs all the time. Dissconnected thermostat wires, still runs. There's 2 wire harness that go to ecm, ones power the other is communication. With thermostat and communication harness disconnected the blower still runs. So I'm assuming there's a short in the ecm?

Any ideas

Sometimes I get 24 volts to furnace gas valve sometimes 10 volts. So obviously it won't fire at 10v. I'm leaning towards board. Can a faulty thermostat cause this

How do you test a hot surface igniter on a furnace or boiler. Do they all require different ohms or amps

Why take the chance

When I run the sink on the right, the middle sink ptrap gargles. If i take the AAV off problem goes away. Everything drains fine. Would that mean AAV isn't opening or it's pushing air instead of pulling or drain is partially plugged? Do they make more sensitive AAV?

How come trapping gas be an issue? It would circulate. Biggest question is why is trapped gas an issue?
