    As an apprentice the knowledge you exude is invaluable. One thing id like to see is you walk through a system like this while also referencing a wiring diagram. Diagrams are very helpful when trying to understand the best way to help out on a job and it helps us new guys follow along to what youre talking about! Love the vids ❤

    Larrs, Lochinvar and Raypak all use the same Igniters, they just use different ends and In a pinch they work together universally, without any problems. If a boiler is firing with an igniter showing less than 3.5 amps consider yourself lucky. I see boiler's that won't run with anything with at least 3.6 amps. Also 3.9 amps is little low for a new Igniter, usually you'll see around 4.2 - 4.3 amps. A little tip, before you put the new igniter in make sure that insulation in the hole isn't rubbing electrode, hense the posible reason for the low amperage on the new igniter.
    Eitheway, I love your content and have learned many things from watching. Keep up the work my friend.

  • @joshhodges5688

    Thought I’d chime again regarding the last issue where it starts and stops. Last time I got that same issue, for me, it was the pressure switch was barely making contact enough to start, but then when the flame ignited, the change in pressure made it open. Haha. I searched for a while! Glad you found the issue!

    • @PipeDoctor
      @PipeDoctor  Год назад +1

      Yeah, so that’s why I was checking for continuous 24 V at the flow switch when there’s a call for domestic hot water or space eating and the flow switch will get power to the gray wire as long as our improving switches are OK and I never dropped out there ever

    @valenzaplumbing Год назад

    The igniter acts as a flame sense as well in this case, no? Like a Weil McLain GV? If you ohm out the igniter and it’s above a certain value, it’s bad and can’t sense the flame. Actually, after looking closer, it’s the same igniter as the GV90+
    Another tip is that you have to test resistance at like 70*F to get a proper reading. I’ve tested them fresh out of the combustion chamber and the reading comes back very different hot as opposed to room temp. I put them in the customers freezer for a few minutes to speed up the process.

    ive just finished a 3 day long ordeal with a Lochinvar Copper Finn II boiler. I had 5 issues with the boiler and they were all random. First i had Fan blowing constantly- proving switch replacement solved issue for 3-4 calls. next i had a stage 2 relay issue that wouldnt click over allowing power to low fan speed on start up so i had no fan power on start up. then i had an ignition module that was giving the DDC relay ghost voltages and also not supplying my F1 and F2 relay within the mod with 120VAC, then I found the flow switch was FUCKED worked 1/2 of the time. Then I went back to the fan and pressure switch. this was the kicker- the fan while plugged into the Molex connector wasnt getting 120V once you unplugged the connectors from fan to Molex you could see there was power waiting at the connector. I traced an alarm fault back to the pressure switch where i had originally put in a universal switch in. apparently the spring cap wasnt screwed in enough so the pressure switch couldnt reset. anyways good client understands shit happens and i learn everyday.

  • @MWestern-m4g
    @MWestern-m4g Год назад

    So if I read this correctly--The ignitor heats up and lets the gas valve open, creating flame.Then the ignitor 120 v input turns off and the controller needs to see a voltage (from the ignitor/flame sense) created by heat to keep the gas valve on. It would be much simpler to have two separate components ie-ignitor, flame sense than the combination ig/flame sense? Now on the next goofy system I would like to see what the peepee voltage is on the ignitor with just the flame creating it!! The controller you had wasn't seeing the weenie voltage from the original ignitor because it wasn't there. I guess next time you see 24 v that goes away immediately look at that stupid ign/flam combo pos. Why to beat this to death. been there done that. I was in the wrong room for 5 hours before we figured crap out. I'll never forget that one. Thanks
