Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
Do you have electronic ignition or a standing pilot (lit all the time)? You'll need to locate the feed valve on the cold water supply line into the boiler (see attached for typical). It will also help if you have a multi meter to do some troubleshooting if the basic stuff doesn't work.
Ok there are a few things we can try to troubleshoot this. If you have a multi-meter we can do more but there are a few things we can do without one. First, is the vent damper open?
It's on top of the boiler in the exhaust vent. Looks like the attached pic. If the flats on the motor shaft are vertical then it's open.
Doesn't look open to me. Give me a shot of the other side. I want to see the shaft between the motor and the vent
Ok, damper definitely not open. You may need a new damper but we can try to rule something else out if you're ok with jumping (connecting them together) the thermostat leads at the boiler. But before you try that show me a pic of where they connect to the boiler
Give me a picture of inside the burner compartment (you'll have to remove the front panel)
You can but I diagnosed your problem. Is my time worthless?
I understand but you aren't comfortable doing what's necessary to fix this. All I can do is tell you what to do. I'll let customer service know you want a refund.
Ok, I need a picture of the inside of the burner compartment.
Yes, I need to see the wiring inside. The 2 series has been around for 25 years and has been through a few changes so I need to know which version you have. I may need more pics but let's start there.
Ok, this looks like a pretty new one. Give me a few to pull the wiring diagram. Be right back
Ok, the 2 yellow leads that disappear into that junction bow on the left look like the thermostat leads. Show me (or tell me) what's connected to them.
That's not what I said. From the multi pin connector there are 2 yellow leads that disappear into the junction box. These 2 yellow leads are shown as the thermostat leads so they should connect to a thermostat wire probably inside that box
You'll probably have to remove the cover to the box to see. Turn the power to the boiler off first
The whirring sound could have been a pump. It's the only thing on the boiler likely to make that kind of noise
OK, that last pic confirms these are thermostat leads. So what you need to do is turn the power off then disconnect the red & blue wires from the yellows and then twist the 2 yellows together (make sure they don't touch the sides of the box or put a wire nut on them) then turn the power back on and tell me if the damper opens.
If it's a crinkling noise it's the damper. The damper shaft should be up & down now not flat. The burner should fire up shortly.
Ok, turn the power off reconnect the blue & red wires (doesn't matter which one they go to) then put the cover back and call a plumber. Further troubleshooting is beyond your capabilities. I'll let customer service know you want a refund
