Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your
issue. First I’ll need some more info so I have a more complete picture of your situation.
What model boiler do you have? what type of radiation? copper baseboard? cast iron baseboard? radiators? hot water coil in air handler?
Ok are any of the zone lights lit on the relay?
Is the draft/exhaust fan running on the boiler? what LED's are lit flashing on the boiler control?
Ok, I need you to answer my last 2 questions
any flashing LED's on the boiler control?
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?
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
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.
The thread won't go away and I'll answer related follow up questions even after you rate me favorably. I'd appreciate a favorable rating.
All I can do is walk you through the troubleshooting which I've done. I can't gurantee an outcome if you do the work. I do take breaks. I'll respond as soon as I can when you get back
I'll respond as soon as I can when you get back.
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
Either one will work.
Do you have more questions?
Are you still with me??
I never "signed off". I spent a considerable amout of time with you and provided all the info you needed to trouble shoot this. I'd appreciate a favorable rating.
