How not to fix a malfunctioning oil delay valve

We upgraded the burner on this older American-Standard boiler at least a decade ago, and whoever maintained it thereafter did this:



I won't mention the oil company's name, but it's one of several Star Gas owns in the Baltimore area. We put a new valve on and upgraded the primary.

    I have done that just to get through the night if I didn't have a valve

    at least they could have gone back and changed it

    That delay valve was a good idea for a clean startup and clean shut down of the burner. Makes maintenance easier when the nozzle assembly is not all gunked up with black carbon coating everything. I agree with @EBEBRATT-Ed. In a pinch, you need to do what you need to do. Then the customer decides to cancel the return trip with the replacement part (now that it is working) and the temporary fix becomes permanent. You never know what the circumstances were.

    You did the right thing getting it up to today's standards with delay on and hopefully delay-off too.

    After you make that expensive repair and you still have the same problem, What will you check next?

    On that valve normally what goes wrong is the connection to the disk that gives the delay under the tape .We use to spin the two wires together ,which bypassed the disk and the valve works again, but with no delay .
