Expert:  Rick replied 1 month ago.

any flashing LED's on the boiler control?

Customer: replied 1 month ago.
I don't believe The exhaust motor is running but when I cut off electric supply I can hear a faint electric motor shut off.On the integrated power control, the power light is solid green and the start cirq light is solid red
Customer: replied 1 month ago.
No flashing leds anywhere
Expert:  Rick replied 1 month ago.

Turn the power off to the boiler wait a minute then turn it back on. Tell me what LED's lgiht up or flash. Does the exhaust fan start? does the limit LED flash or light up?

Customer: replied 1 month ago.
Power and start circ lights on solid immediatelyNo other lights come onNot 100% sure about exhaust fan but I see a lot or attached to exhaust pipe which is not running.I do hear some faint motor running when it powers up
Customer: replied 1 month ago.
I don't see a "purge" ledThere is a "flame" LED and a "pres switch" LED and a "limit" LED in addition to the other two I mentioned but none of these three light up
Customer: replied 1 month ago.
There are no flashing LEDs anywhere
Expert:  Rick replied 1 month ago.

Faint motor could be circulators running. The exhuast vent is connected to the draft/exhaust fan. The purge LED is on an earlier version of this control. If the fan doesn't run nothing else will happen. You need a multi-meter to troubleshoot this further. Do you have one?

motor
Expert:  Rick replied 1 month ago.

Ok, awaiting response to my last post

Customer: replied 1 month ago.
I don't have a multimeter. What specs do i need to look for on a multimeter when I get one ?
Expert:  Rick replied 1 month ago.

Any multi-meter will do the job. You need to test AC voltage. The possible culprits are a bad fan or a bad control. If you have 120 volts AC to the fan then the fan is bad and you should probably leave this repair to a pro who is familair with this boiler. If there is no voltage to the fan (when power and circ LED's lit) then you probably have a bad control. I suspect a bad control because you should have at least a flashing LIMIT LED at this stage.

Customer: replied 1 month ago.
OK it may take me an hour or so to get a hold of a multimeter should we just leave this conversation open in the meantime ?
Expert:  Rick replied 1 month ago.

Customer: replied 1 month ago.
Ok I'm back and I have a multimeter
Expert:  Rick replied 1 month ago.

Then set your meter to 200 volts AC scale (or similar) and unplug the fan connector leads at the control and probe the W & B terminals. Do ths after cycling the power off then on again and after the circ LED is lit. I'll be back in about an hour

Customer: replied 1 month ago.
Meter can be sen to 150 ACV or 250 ACV
