Hi everyone. I have a Triangle Tube Solo 110. It is about 5 years old. When it starts up, I hear a horn-like noise for about 15 seconds, then it stops when it ignites. I pulled the PVC off and the noise pitch changes and if I put a few fingers over the venturi, it muffles the noise. The fan appears to be spinning fine and it spins with no horn noise. Before and after the noise, I can still feel air being pulled in.
Any ideas? I've come across some posts where people have had a cracked venturi. Or a dirty venturi? Could that do it?
TIA!
