Customer Question
My boiler is not...

My boiler is not lighting. I can see that the pilot is burning. I have tried switching power off, and the system makes a noise like it is trying to light but does not. Noticed this this am as I was changing batteries in thermostat. What next?

Contractor's Assistant: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?

I don't suspect the thermostat.

Contractor's Assistant: Do you plan on doing the work yourself?

Our local boiler expert retired a couple of years back, so, yes, I'll be doing the work.

Contractor's Assistant: Anything else we should know to help you best?

I don't think so, Weil McLean gas boiler, is about 20 years old.

It is EG, for water, fired by natural gas.
HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

Does it have a vent damper? do you have a multi-meter to do some voltage testing?

HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

Ok, first thing to check is the spill switch which is attached to the open bottom draft diverter just below the damper. Push the small button between the leads. If it clicks you have reset it. If it doesn't click it wasn't tripped.

I have the cover off vent damper, what shall I test?
Customer reply replied 3 months ago
Only button I see will not move. There is a 2pos switch on the side that I moved to other position.
HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

That's not what I said. I said BELOW the damper on the draft diverter. Look for the 2 wires to it which are separate from the damper wiring

There is nothing below the damper.
HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

If you have a damper you have a spill switch. I need pictures of the damper and what's below it as well as all the controls.

Again! BELOW the damper NOT ON THE DAMPER! Back up, give me a much wider angle

HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

Ok, the spill switch is attached to that sheet metal box with the open bottom below the damper. Check the other side

Ask Your Own HVAC Question
Customer reply replied 3 months ago
There is nothing on the other side, no wiring, switch. Just sheet metal.
HVAC Technician: Rick, HVAC Supervisor replied 3 months ago

I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
