Customer Question
I have a Dunkirk...

I have a Dunkirk boiler with a UT 1013-15 electronic control board. Sometimes it cycles without problems, sometimes the red purge light flashes on and off while it "clicks and whooshes" without progressing through the sequence. Had local HVAC out. They brought the wrong part. I don't know if the board is the problem, but I found one online and am looking for a you tube to see if I can change it out myself. So my question is, is the flashing purge light, click, swoosh, likely to be that control panel?

Contractor's Assistant: Are you an HVAC professional?

No I am not. And I had no intention of trying to do this myself, and yes, I can call someone else, but they have been out 4 times, it's costly, and I have the same problem.

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

I'm hoping to find out the problem so that when I have someone else out, I won't have to have them out a number of times to figure out what the problem is. It isn't really cold out yet, but it will be.

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

I took pictures and video of the panel when this is occurring. It will work for a few cycles and will suddenly stop working and get stuck on purge. I think that is the sum total of my knowledge about the problem.

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

I don't know what your whoosh noise might be (do you smell gas?) but a flashing purge light is a draft (fan) issue. Is the draft fan running? Check the tubing connected to the darft pressure switch (see attached). Is it blocked, kinked or disconnected?
