Utica MGB75HID boiler wont start
This boiler was installed in 2004, but I have only owned the house since 2008. Both winters 2008 and 2009 the boiler worked fine. It has a Honeywell Ignitor S86ooM, a on/off toggle switch and a dedicated breaker. The breaker is on and in the past two years, when I flip the toggle to fire up the boiler for the winter, it starts right up. This year, nothing. I have checked the breaker, and all of the other electrical and electronic connections, everything seems fine, except it makes no noise. It doesnt even appear to be trying to start up. I have also checked the thermostat red and white wires, both are connected.

Does the guage show that the boiler has any water pressure in it. Does sit have a low water cut off.

The gauge isnt reading anything. Not sure about the Low water cut off. How would I find out? (No owners manual)

May not have one. But if you do. they can prevent your boiler from working.
