Re: HTP UFTC-140W Recurring Error Code 11 Issue
That’s a lot of unrelated perceived value you received. Flushed both sides being? Fire and Watersides of the heat exchanger or supply and return. No mention of condensate trap. 6 years of nat. Gas burning : poorly tuned could be a dirty heat exchanger.
I have found genuinely bad HTP boards. All else should be proven good. Assuming a bad board is different than witnessing / identifying evidence of a board fault. Assuming is flailing. It’s doing something because you don’t know what else to do. 15 tries to ignite and then it does and has a fairly close to good mixture burn would have me looking at the gas valve. Does it receive proper voltage and current during the cycle. Does it actually open with gas flowing when it doesn’t ignite? Looking inside at the burner around year 6 isn’t a bad idea. Cleaning the fire side heat exchanger before it clogs is good. Look for good insulation and a clean normal burner. Maybe there’s a small leak that fouls things and 15 tries dries it out enough to ignite. Is there actually a spark happening where it should? A good tech will be able to conclusively answer these questions.

comcast were pioneers in evaluating representatives in such a way that they are discouraged from solving your problem but everyone does it now.

Re: Basement radiators are hot when thermostat is not calling
Stuck flow valve. Turn up the zone to run the circ. Tap on the flow valve to loosen up and move out whatever debris is holding it open. Then turn the zone back down and wait a day to see if the rads. cool off.

Their strategy to keep customer support costs down is working.
Re: Humming to Hold Music
A lot of places are starting to use a call back option. You leave a message, and they call you back. If done right (sometimes questionable) its better, you can hang up and do something productive while waiting for the call.
Re: 24v HVAC control (US) - FAN (Green) always engaged when call for heat, is that normal?
As mentioned it is how the thermostat is programed .. I prefer to add a aquastat to the return pipe to turn on the fan when the coil is hot enough heat and will shut it off when cooled down ..

Re: Suntec A2VA-7116 Fuel Pump
I find a lot of oil pumps from the different manufacturers leaking from the pump seal. I rarely find any that fail to pump. I don't consider any of them better than the others.
Re: Periodic fail
If you do not have the Carlin 70200S PRO primary control (with a 5 year warranty) then you are just guessing at the problem. …and by firing the parts cannon at the problem, so far, you have missed the target. The Carlin 70200S PRO has many diagnostic features that can pinpoint the cause of the burner lockout in the Error History Log. You may find that the Ignitor had low amperage on the flame failure cycle. You may find that the flame failure happened during a run cycle. You may also find that the flame failure is a result of the high resistance from the cad cell indicating that the cad cell is pointed at the wrong place and does not see the flame very well. along with many other error codes available. Each message will point me in a different direction to the source of the problem.
When I get stumped by an intermittent failure, that never happens when I am there to see it, I recommend that Carlin primary control, so I can look back at each event in the log and find something like "No Ignition 34 cycles ago" in the log and address that problem, so I don't have to make an uneducated guess with a parts cannon.
