any flashing LED's on the boiler control?

Ask Your Own Plumbing Question
Customer reply replied 11 months 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 reply replied 11 months ago
No flashing leds anywhere
Plumber: Rick, Construction Supervisor replied 11 months 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 reply replied 11 months 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 reply replied 11 months 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 reply replied 11 months ago
There are no flashing LEDs anywhere
Plumber: Rick, Construction Supervisor replied 11 months 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?

Ok, awaiting response to my last post

Customer reply replied 11 months ago
I don't have a multimeter. What specs do i need to look for on a multimeter when I get one ?
Plumber: Rick, Construction Supervisor replied 11 months 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.

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 ?

Ok I'm back and I have a multimeter
Plumber: Rick, Construction Supervisor replied 11 months 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
